Flying R/C Model Aircraft

Contents

Stealth B2 Bomber, from AirTech

  • Purchase Price: $79.99 cdn. from Toys-R-Us.
    • Comes complete with controller, NI/MH battery for aircraft, and charging station.
  • Other costs required before first flight: aprox. $30.00 cdn.
    • Requires 8 AA batteries for remote control
    • Requires 6 D batteries for aircrafts' battery charging station (I use a generic quick-charger instead)

Some Stats
Weight: 120g
Thrust: 25g x 2
Battery: 300mAh, 4.8v, 4-pack of 2/3length AAA batteries, configured in a 2x2 matrix.
Wing Span: 700mm
Propellor: 75mm x 2
Material: EPP
Class: Park Flyer
Controls: Throttle, Ailerons, Elevator (through differential thrust - so aerobatics are not possible) Homepage: Interactive Toys - Replacement parts and information.

NOTE: Mine was shedding stickers even before the first flight. But that's ok, a B2 should be solid black anyway :-) As you can see, the profile of the wing is not flat, it has angles along its' length. But when it's in the air, you'd never know. It looks like a perfect silouette of a B2 as it flies over you. There are no stickers on the bottoms of the wings, but there are stickers on the sides of the lower body. They are not visible as it flies over.

The aircraft is built of strong EPP Foam. It can withstand nose-dives from insane altitudes (I've tested it myself several times). If you *DO* manage to break something, all it takes to fix-er-up, is some "white glue", such as the stuff used in public schools. Then after it's dry, tape the area (with black electrical tape) for extra support, and off you go again! Note that this model has a very gentle glideslope, and has no elevator, so you really have to look ahead to avoid potential disasters. If you're getting into trouble, it's a long glide before you can land it.

E-Starter, from GWS

  • Purchase Price: $79.99 cdn. from local R/C Hhobby Shop.
    • No controller with this one - you must take the leap and purchase a generic R/C aircraft transmitter. They will run you anywhere from about $80 to $500+ if you want computer assistance such as mixing. A mixing feature allows you to, for example, add more rudder as you use the ailerons (for automated co-ordinated turns), and many other things. On the bright side, once you've made this purchase, you will be able to fly many other model aircraft with the one transmitter.
  • Other costs required before first flight:
    • Glue (optional - the kit did come with some mystery-brand glue, but I didn't use it)
    • Standard R/C aircraft parts (reciever, servo's, ESC, etc. )

Some Stats
Weight: 15oz
Thrust: (Unknown)
Battery: 750mAh, 9.6v, 8-pack of 2/3length AA batteries, configured in a 3x3 configuration.
Wing Span: 37.8 inches
Propellor: gws 7035
Material: Foam
Class: Park Flyer
Controls: Throttle, Ailerons, Elevator, Rudder.
Homepage: GWS

The aircraft is built of strong foam. It can withstand some pretty rough landings, but the landing gear is often liberated from the fuselage. If you do manage to break something, all it takes to fix-er-up, is some more glue to slap'er back together. Foam is easy stuff to fix :-) unless you manage to crash at such a rate of speed that the foam shatters into too many small pieces. I've not done it, but I'm sure someone out there has found a way.

StickPlane, (my experiment)

  • Purchase Price: $cheap.
    • This thing was thrown together with some foam, 2 servo's, a motor, and the Rx and ESC from my E-Starter. I built it to see if I could build something light enough to fly. It did! But it sure wanted to do left turns a lot! (not well balanced, but then I didn't spend long balancing it). It made 3 flights total. 1st flight was really squirly, and ended in a rough but ok landing. 2nd flight was much better. I flew several nice circles around myself (to the left), and finally landed it gently. 3rd flight took the path of a lawn dart. (the elevator linkage had come off but I didn't check before pitching it up into the air with full throttle)

Attitude 3D Profile, (Todd's Models)

  • Purchase Price: $79.00 CDN.
    • This aircraft may look a little funny, but it is VERY powerful. It can stand on it's nose, and hover on the prop thrust alone (and that's only at 1/3rd throttle, too!) It has a "profile" fuselage, meaning light, strong, and very low drag. It has full-span ailerons with 45' throws, allowing it to loop within it's own length, as well as a giant rudder and elevator. All this adds up to more power and control input than the aerodynamics of the aircraft can handle, thus the term "3D". It's possible to do unusual aerobatics by flying on the boundary between "in" and "out" of the flight envelope. An example being hovering, where the aircraft is fully stalled (it's not moving anywhere, so there's little airflow over the wings), however, there is enough airflow from the prop-thrust passing over the control surfaces, for the pilot to continue controlling the aircraft and keep it balanced in the upright position. Alas, Todd has discontinued this amazing model :-(

Some Stats
Weight: 19oz
Thrust: 47oz
Battery: 2100mAh, 11.1v, TP2100, 16amps static.
Wing Span: 34 inches
Propellor: 11x4.7 slowfly
Material: Balsa with SoLite covering
Class: Park Flyer
Controls: Throttle, Ailerons, Elevator, Rudder, (Flaperons).
Homepage: Todd's Models (Attitude is discontinued)

The aircraft is built of balsawood (mostly competition quality), and has a very light and strong frame. The wing spars had a built-in jig to assist in the building process, and worked very well. The plane can do everything I hoped it could do, and will last me a long time, I'm sure :-)

XF-11 (My second scratch build)

  • Purchase Price: No idea :-(
    • This plane was inspired by an accident I had with my Attitude. I settled on a P-38. Mid-way through design, I saw the movie, "The Aviator", and was very surprised to see a plane that looked like a P-38, but had a more square tail rather than the egg-shaped thing the P-38 had. I like squared-up tails much better, so the design quickly changed. It's taken about 2 months of planning on the computer (and learning CAD), and another month or two of actual building time, but it's finally complete. It's a FAST plane :-) 30kph stall, 70kph max speed. Scares the snot out of me when I fly it.








F-15, (jetset44's free plans)

  • Scratch Build - cost of parts: $20.00 CDN, (plus electronics).
    • What can I say. This is an absolutely brilliant design. I looked at it online, and I read the newsgroups where other people discussed their build, and their first flights, and how some had less than successful first flights, and I feared this whole jet thing very much. But I built it anyway. And WOW, am I ever glad I did. This thing was easy to build, and flies SOOOO NICELY! And it looks absolutely stunning in the air, especially going vertical. It has enough speed to scare me when I crank up the throttle for a low pass, and it can slow right down for a very gentle belly-flop landing. It's a lot of fun to fly something that knocks people's socks off when they see it, and jets seem to do that every time. What more can you ask for, and it's FREE!!!
  • Additional parts needed: 3 HS-55 or similar servo's, motor, reciever, and a bit of scratch-building experience.

This model is made entirely of foam-board (the foam with paper on both sides, that you can make signs with). Soak it in the tub for an hour, and you can peel off the paper. No glue was used to apply the paper, so it comes off cleanly. SoLite Covering was used, to create the color scheme, while also adding strength to the leading-edges of the wings. I also added balsa strips to the vertical tail, for a touch more rigidity. The nose art and tail markings were created by printing black&white clip-art and numbers, and then peeling the backing off some black covering, and sticking it to the back of the printed paper. Then, I carefully traced the printed items with an exacto blade. After cutting out, separate the paper from the covering again, and apply the covering to the aircraft. Black makes very nice decals this way. Some other colors are too transparent on their own. Yellow can be made more opaque by putting white behind it. Anyway, on to the test flights. On day two of flight trials, I had just finished a high speed pass, and was going vertical when something flew off the aircraft. That freaked me out pretty good. I cut the power, and coasted around for a quick landing, and discovered it had shed the (taped-on) canopy. I found the canopy, but had no idea where the tape went. Until my buddy pointed out it was stuck to the leading edge of the right vertical tail. (The canopy is removable since the battery is under there). Now it's held in place with a screw.

Clever Boy ARF, (Green R/C Models)

  • Purchase Price: $200.00 CDN.
    • This lovely little 9oz aircraft was a prize I recieved at the local fly-in, one sunny afternoon. I couldn't believe my luck. Credit where credit is due - Racing Devil Hobbies of Richmond BC supplied the prize, and I cannot thank them enough for it. It flies like a trainer, and with enough power to loop, or climb aggressively at about a 45' angle. This model is an ARF - meaning "Almost Ready To Fly". Open the box, and find an aircraft that's mostly built already - just need to glue the tail to the fuselage, mount the servo's of your choice, add a reciever, and you're ready to go. It is already covered, with some sort of plasic shrink-covering like I use on my other models, but this stuff is much stronger, and would likely resist a puncture if it encountered a tree.
  • Additional parts needed: Glue, 3 pico servo's, and a reciever.

Some Stats
Weight: 9oz
Thrust: unknown
Battery: 650mAh, 9.6v, 8-pack of 'AAA' NIMH batteries, in a 2x4 configuration.
Wing Span: 36 inches
Propellor: "Tower Pro" EP-1030 slowfly
Material: Plywood and Balsa, with unknown brand of covering
Class: Park Flyer
Controls: Throttle, Ailerons, Elevator, Rudder
Homepage: none known

The aircraft is built of plywood and balsa, and has a very light and strong frame. The motor mount has a spring-action, so if you nose-in, there's a chance you won't bugger up the model. I hope never to test this feature. The wings have quite a bit of dyhedral, making the plane naturally return to level flight if you stop steering. Stalls are the one drawback of this model. The model also sports some nice little carbon-fiber landing gear. This is the only model I own which can taxi on the grass (which is of very poor up-keep) at the local flying field. AND, it sports a tail-wheel tied to the rudder, which is really nice! In flight, a stall with this model means one wing drops REAL QUICK, and you're in a nose-down vertical position before you know what happened. It's a real floater though, so you have to kill the throttle, then hold the nose high as it slows down, to even induce a stall. As long as you let it glide itself (without power), it's happy. I think this plane needs to acquire some lights, for a little night flying, sometime soon :-)

MEMORABLE CRASHES

Death Spiral 101:

Heading for the forest at about 80 feet. Don't want to go there. 3rd day out flying. What to do? Hold maximum left throttle, Captain! The aircraft tips over on it's side. It's a B2! There's *NO* lift when it's sideways, Captain! The aircraft drops into a vertical spiral, and within about a second, has accelerated to an ungodly rate of speed (I'm *still* holding maximum left throttle). It then nose-dives into a loose-gravel area surrounding a (vacant) swing set on the edge of the forest. Damage? none, to my total amazement.

Fencing:

There's a chain-link fence down the center of the park, separating the baseball diamond from the soccer field. It's of average height (4-5 feet). I'm all over the place, seeing as I've only been out a few times and am still getting used to simply turning. I've crossed the fence a few times and returned it successfully, but one time, after completing a turn on the other side of the fence, I find myself dropping in altitude as I approach the fence to return to my side of the field. As I see my plane drop below the line of the fence, and see that it is, indeed, still on the other side, I decide to floor it, in hopes of 'hopping' over the fence. No such luck. The plane rises, but just as it's about to clear the fence-line again, it instead, meets the fence. As it skids over the top of the fence, something catches on the underside of the plane sending it cartwheeling end-over-end through the air. When it finally lands on the ground again, I pick it up and inspect it: minor foam separation on a funny foam bump in-front of the on/off switch. I suspect that foam is there just to protect the switch anyway, so no harm done.

Girlfriend Gets the Controls:

I'm stupid. But only because I picked the *DUMBEST* spot to give my girlfriend a chance at the controls. Small park, lots of fencing, trees, pools, etc. etc. very near by. No people near by. NOT GOOD ENOUGH :-) I show her the controls, tell her to hold full throttle, and then I give it a throw. The plane rises, and banks off to the right, and then BZZZZT. Stuck in a tree. Fortunately, it happened so fast, it was just barely out of reach. I got a hoola-hoop I had in my trunk, and tried to snag it, but couldn't :-( I also tried bungie cables from the trunk, still no luck. I could reach the base of the branch with my plane on it, and bounce up and down and shake the shit out of it, but the tree just won't let go :-( At this point, some nice people come by with a big pole they had in their trunk, and I was able to poke the plane out of the tree. They then advise me that there is a HUGE open park just over that rise. sheesh :-) Off we all go to do a little more flying :-)

40-feet and climbing:

I took my plane out to a nice park I found that is completely enclosed by trees, and seems to always be virtually devoid of people, save the odd BBQ'er around the edge. I go to the center of the field, and give it a throw, fly it around a bit, then practice a landing over near the corner of the field. I walk over, and pick up the plane. At this point, two kids intercept me and ask if I'm putting on an "air show". I tell them I'm still learning, and then launch the plane again. Notice, I forgot to go back to the center of the field :-( It flies out over the field, then I bring it back around to me again. Unfortunately, I'm not thinking far enough ahead, and when it gets to me, I'm screwed. It's way up high, and I realize as soon as it's close, that it's destined to go into the trees. I just watch helplessly as it does just that. Getting this one down took about 4 hours of my life, and most of my sanity. I must have thrown various things into the tree 40 times. Then I got rather warm, so I removed my coat. I eventually got the plane down by throwing a hammer (with a string attached) over the branch which was holding the plane. Once I'd finally accomplished that, I tied an extension cord to the string, and then pulled that over the branch and down the other side. Now I had something strong enough that I was able to bounce the branch vigerously, until the plane was released. What a project. I was SO happy to *finally* have my plane back, that I forgot my coat at the tree instead :-(

Things that go "PING!"

When an aluminum bat strikes a baseball, you hear a sharp PING! sound. Today, I discovered that my styrofoam stealth, when striking an aluminum pole, produces a remarkably similar PING! sound. It also induces an uncontrollable tumble that would cause even the most extreme pilot to black out. Unfortunately, the subsequent collision with the ground caused the right wing to be severed about 2 inches from the wingtip :-( This is a very thin part of the wing, and only time will tell if glue will hold the wing together in this area. This may be the beginning of the end of my first aircraft :-( Preliminary test-flights seem to indicate the repairs will hold just fine :-)

Things that make you scream "NOT NOW!!!"

For one, if you're hovering your plane just above head height, and the battery cuts out, that's a good time to scream "NOT NOW!" Because that's about all you can do while you watch your plane tail-slide most of the way down, then flip over just in time to crater into the ground. That little accident caused the nose to bust clean off, whip around and use the spinning prop to chew the first two ribs clean off the left wing. The right wing didn't get away unscathed either, it lost two outer leading edge ribs as well. During the impact, the tail bent over so far I swear the tail almost touched the ailerons, then, remarkably, sprang back streight again. I couldn't believe my eyes. I was heart broken. My beloved Attitude was done for the day. I contemplated buying a new kit, but then a week later, gathered the courage to try to fix my (first) balsawood kit. It turned out to be really easy, even building new ribs!!! I just scanned the originals from the plans, printed them on paper, and made sure they printed at 100%, not 97% like my printer wants to do by default (WHY!?!?!?!), and used them as templates to cut and sand new balsawood. It took all of one evening to rebuild the leading edges of both wings, I was very surprised. Things went so well, I was inspired to try to build my own aircraft from scratch. The XF-11 was the result! And yes, my Attitude still flys just fine :-)

War Wounds

My stealth has seen some pretty harsh crashes. Here's it's current condition:

My XF-11 after test-flight #3. I stalled it with the flaps down and not enough throttle. I have re-built it from the parts, it went back together like lego. I will not likely fly it again, but keep as a static model.

My Attitude has been through many an accident. It has had it's nose snapped off 2 times, as well as broken most of the ribs across the leading edge of the wing at-least once. But it keeps on flying :-)
