I fly many 049 planes I have built up from plans such as the American boy and the Ambush (049) 24" wingspan amongst many other control line planes I have built from scratch. All for Cox 049, surestart and TD engines. I have been playing with building from scratch RC Air Cars and was wondering if an RC plane with a profile fusualage and slab wing like an american boy would fly as an RC plane if I fitted micro servers to the rudder, elevator, and I have good working throttle control on it.? Basically I figure the craft may have a very short life, hence profile fuse and slab wing would be a great way to go if they will fly as an RC not a CL plane.

Thanks,

Yea Yabby , from what i have seen people use foam or built up wings , It would probably fly very fast to keep the slabby in the air on a profile fuse . Easter Bunny Maybe you can bee one of the first to experiment with it ? Easter Bunny

yep, Eric, its almost built, im right now modding one of my very small 13" flat wing 2.5mm and profile fuse 2.5mm and usually a TD on them and 42 foot lines, they go like crazy and are really hairy to fly. Im taming it down with an 049 surestart. Just glued a rudder on it, and am mounting the two servos for rudder and elevator, and will need one for throttle. As a CL plane we can hand launch these with someone holding it and pointing it upwards vertical and just letting go and it climbs straight out of their hands. Lol. Weighs nothing. So Im thinking of trying to fly it by launching it from one hand b y just letting go, and the controller in the other. Lol. sunny cheers

Hopefully fly it tomorrow or next day. might be a very short flight. Lol. But thats not new to me anyway. So, as Eric suggested I will find out for myself. I suspect if it works, it will be very fast and very difficult to fly and probably need ailerons to have half a chance. Find out soon. HaHaHa.

Thanks Eric! lol! Thumbs Up I figured if a Cox engine on a rag can fly, then if I put some rudimentary control surfaces on a plane as Im using it should behave closer to a missile than a plane but with more control than a rag. Lol. Im going to have to ask a local cocky if I can fly it in one of his empty wheat fields as Im a bit concerned about flying it at the local sports Oval/Park. RC Plane And I can walk to the beach in a minute which is a huge remote beach but that is a guarantee of sand in everything, the local Cockys padock will be fractionally better at the moment as wh have not had any rains and the sheep have eaten all the stubble. I kind of figure, even if I can fly it and it is flyable, its going to result in a broken plane and a possible engine strip down and clean. Buty thats better than embedding the plane into some 12 year old kids skull dowen at the sports park. lol! Mind you.......... Old Bugger

Bloody hell, servos, even micro, and really small battery and receiver are heavy! Might end up with a TD on the nose of it yet to negate all the extra weight! Im going to have to do some research on much smaller servos! I bet I can get them on the Net. My local hobby store probably just has what it calls micro servos that are not really!. Lol.

Gotta do some test runs of the receiver failsafes and the carby shutoff. That might be important yet!!! Lol. They have been tested and work well on my RC Cox cars, but want to be real sure with the plane.

yep, thanks Eric, looks like they are 'alleged' micro servos. Not what I would call 'micro' but still. It is what it is. The plane weighs nothing, so they will be ok. and I can use them to balance it a bit better maybe. Lol

Yabby what you need is nano servos and a 400mAh NiMH battery that will not overload even a 010 powered RC plane. I have built and flown various 010,020 and 049 COX powered RC birds and the above electronics fit them all. Where you want to use micro servos is some larger 049 powered planes and all larger up to the 0.15TeeDee powered ones.

Thanks Andras!! Thumbs Up cheers

I figured something much smalledr must surely exist. My little plane is looking like a servo with wings! Lol.

after this brief adventure, I will purchase some servos as per your suggestion!
