  1. I want to build a rc plane and helicopter. Does anyone know how I could build the wings and rotors?
    Please put a link.

    • Building an RC plane is harder than you think. If you have never flown before, learn to fly first. Other than that, do you plan on putting the rotors on the plane? For building the rotors, I would jut recomend buying some. Its way to hard to build them out of wood, then balance them to perfection. For the wings, you can use foam (like insulation foam from Menards, or foam board from Target or Walmart) or you can get balsa wood from most hobby shops. With balsa, you will need to use “film” to cover it. Film is a covering you use heat to to make it shrink and stick to the balsa giving the wing lift.

  2. where can i get just the RC model of a plane?
    i’m planning of building a RC plane, but i don’t have the right equipment to build a perfectly balanced and a level plane ( the fuselage, wings, tail etc) so i wanted to know where i could get a TWIN PROPELLER RC model of a plane, can someone send me a link to a web page that sells just foam/ plastic/ aluminium RC model aircraft. thanks

  3. How should I go about building a remote control aeroplane?
    I want to build a remote control aeroplane. I have a good knowledge of electronics, but i dont know how the flaps would work and how to make the airfoil and all that stuff.
    I wad just going to use a remote control circuit from an old RC car or something.
    I dont really want to buy one, because it would be rather expensive, trickier to modify and might be a bit weaker.
    What should i build this plane out of and how would i get the flaps working and the airfoil?
    Or am I being a bit too ambitious?

    • Hmmm… LOTS of questions!! LOL

      I spent my entire childhood, teenage years, and 20s making various RC models, mostly of the flying variety.

      These days, most RC planes are made from polystyrene foam. Commercial Ready-To-Fly ones tend to be made with the polystyrene injected into a mould, but if you use the foam method at home, the way to do it is to use some resistance wire rigged up to a home-made H-frame and attached to a car battery charger (needs to be a decent high-current charger or it won’t get the wire hot enough).

      You make templates of the aerofoil – attach them to each end of the foam wing blank, and then run the taught hot wire over the templates. Then you veneer the resulting foam aerofoil wings with lightweight obeche veneer…


      …but, to be honest, it’s too much to explain here and your best bet would be to buy a kit, if it’s your first effort. Do NOT get into glass fibre techniques on your first model. Just don’t!

      You will actually find that it’s no more expensive to buy a kit than it is to buy the raw materials and make it yourself (I know you won’t believe that, but you’ll find out the hard way! Take it from someone who’s built numerous kits over the years and who’s made numerous own-designed models from raw materials, too!).

      I really would like to help you with pages and pages of informative instructions but I really am giving you good advice by advising you to buy a kit for your first plane. It’ll teach you a lot and you can then use that knowledge in the future if you wish to try designing your own (or making one from a plan).

      You can use the R/C gear from a buggy.

      Make sure the first model you get has plenty of dihedral on the wings (when you look at the wings they dip at the centre join, or to put it another way, the wing tips rise upwards from the centre. This will make the model very stable and forgiving when you are learning to fly it.

      Also make sure the wings are not too fat but not too long and skinny. Again, this will help make the model easier to learn to fly.

      Also make sure the wings do not taper much towards the tip. You want the wings to look quite rectangular. It’s not the most beautiful but it’s the most stable for you to learn to fly.

      Basically, tell the model shop you require a 2-channel or 3-channel ‘Trainer’ (if your existing R/C buggy radio gear is only 2 channel, then let the shop staff know that. PLEASE do not be tempted to just go for the most beautiful model in the shop – *YOU NEED A BASIC MODEL TO BEGIN WITH* with the characteristics I have described. If you ignore this advice, then your model will not be forgiving to fly and you’ll more than likely wreck it in no time, becoming disheartened, wasting your money, and your time.

      If you want a plane with a propeller (2-stroke, 4-stroke, or electric) then remember that you’ll need a minimum 3-channel radio because you always need a minimum of 2 channels for elevator and rudder (or ailerons). The 3rd channel is, fairly obviously, for throttle control. My interest was mostly in slope-soaring gliders, so 2-channel did the trick for me, mostly (elevator and ailerons).

  4. Where can I get free plans for an RC Airliner?
    Hi, I plan to build an rc airliner out of wood (From scratch) but all I need are the blueprints and the dimensions for a jet powered boeing plane. Would anybody know of any websites that give those free? I also need to know where I could get little hydraulic cylinders to power the plane’s ailerons.

    Any help is appreciated!
    Thank You in advance.

    • Have you ever flown planes before? If you haven’t, I wouldnt suggest this project. If you have, I would suggest using a regular toy foam plane and converting that into an RC. Wood seems pretty darn heavy to make an RC Airliner…
      Also, no, they dont give out free plans. You could buy an Airliner from E-Fliterc.com.
      The one on there should be much cheaper than if you were to build one yourself.

  5. What foam should I use for an rc plane?
    I am planning on building an rc 6ch private jet, however, I’m unsure what foam I should use. I want a foam that I can use for the body and wings of the plane. Also, I have a really low budget so the cheapest option would be better Thanks
