Hi dudes! A few weeks ago i aquired a remote control aircraft . Although the main airframe was in good shap, i decided to wreck it and build a new one from the parts. Now i have a problem. does anyone know what the rule for wing-shape-to-lift is? I'm going for a flying wing design powered by an internal combustion engine, but in order to find out what it'll fly like, i need to know how much lift i will get out of it. Any ideas? Thanks in advance.
Akula.

PS. By the way I dont know if i've put this topic in the right forum. Never seen a forum about RC planes!

Hi... another RC pilot. I'm not too sure of your wisdom in buliding one unless you have flown before. I fly a zagi, so go to www.zagi.com to see 'em. Flying wings.... I wouldn't try to learn on them. we don't have a RC Planes froum here ( I keep trying to get one! lol). Try RC Groups.

Dan's right. If you've never flown before buy a good trainer and attend a flight school at your local RC club.

I fly a Hobbico Avistar which is a good well rounded trainer.

I still haven't completed my Vmar Tomahawk. Lesson learned Vmars uses cheap parts.  

Building an airplane is a lot harder than it looks. Wether it's balsa and plastic or steel and aluminum, it requires complex math and precise measurements. I've got two scratch builds nearing completion but I don't know if they'll ever fly.

RC Groups is a good one. Also try RC Canada. www.rccanada.ca They've got some good info on the main page.

Speak to hagar or rifleman both are very knowledgable in this area.

My advice would be the same as Dan & Iroquois. I wouldn't recommend a flying wing to learn on, especially one you designed yourself. Join a club & get advice from the members on a suitable trainer. Most RC clubs welcome junior members & have reduced fees. They will also have their own flying fields where you can fly safely without annoying the general public. Make sure you have proper 3rd party insurance. This is usually included in the club membership. Take advantage of their training programme. All decent RC clubs will have one & many have their own equipment - trainer & buddy box so you can try it without spending out on your own.

Please remember that model flying can be dangerous. Never fly alone & treat powered models with respect. I've seen serious injuries caused by comparatively small I/C engines. Electric motors tend to be more dangerous as they will keep running unless they're switched off. The motto of the BMFA (British Model Flying Association) is "Safe Flying is No Accident".

I'm not trying to discourage you. This is a great hobby. If you try to go it alone I can almost guarantee the result. First time out on the field you will smash your pride & joy to pieces & give up in despair. If you start out properly you will probably enjoy model flying of one sort or another for the rest of your life. You will also meet a lot of interesting people & make plenty of new friends.

Imagine yourself standing in front of a 12 foot tall ladder.........you want to be at the top, thats natural, as you know you are going to enjoy the view, but there are two ways that you can see to get there.......just jump up and grab on to the top rung, or start climbing from where you are - the bottom -

Yeah I once looked into it and was advised that if you want to waste your money do it alone. So I left it there. My Dad always wanted one too and couldn't get his hands on one.

Unlike the other posters I'm going to assume you have RC experience (probably not a good assumption, but I feel like being different).  If that's the case then you've probably already learned to fly and probably have some experience building your own plane and are simply looking for info on wing design.

If that's the case than let me tell you: there are no easy answers.  You can go to school for years and still not be an expert.  That said, in RC you can make just about anything fly.  Some kits are little more than a pizza box, engine, and some control surfaces.  If you're a good enough pilot you can fly it.  But that's not what you're asking.  You want to make something that flies and flies well.  Assuming you've mastered every skill except wing design, try your local college library (it's a technical subject that a small public library may not have) for books on wing design.  You may even be able to find one specifically addressing RC planes at your local public library.  Warning: you may need to brush up on your differential equations!

Thanks, dudes!

I've seen serious injuries caused by comparatively small I/C engines.

Yeah, same here. google search for "Guy being hit by RC plane" and you'll find some gory stuff. Thanks for all your advice, and i will be reading up on a load of stuff. But also, how big do you think i should build it? My best friend thinks it should be around 1m wingspan, but i reckon it should be more like 1.5m or maybe even 2m. Please advise!
