Wingdragon BL Motor too Powerfull?

ookid · Jan 07, 2010, 12:05 AM

Hi, a while back a got a 2212/6 Brushless motor to use in a plane and it has been sitting on the bench here for a while now. My question is, would it be too much for my poor humble WingDragon? I would run it on a 3 cell battery with a 6/4 prop attached. If it does work and not rip the plane apart, would someone with reasonable flying skills, such as myself, be able to fly it? Thanks for any input, it is greatly appreciated.

I currently use TowerPro 2409/12T motors in both my Wing Dragon's/Begin Air planes. With a 3S2200mAh lipo and 7x4 props I get around 190w or so. Both have heavily reinforced wings, tails and motor mounts. I have one with an onboard GPS logger and I got 86mph in a dive. It should handle the power with proper mods. DO IT!

Thanks for the response but I don't think that you realize that the 2212/6 is a motor with almost twice the Kv of the motor that you listed as using. It is a 2200Kv motor and I think that's way to powerful for the WD. Again, thanks for the reply.

I don't have a Wing Dragon but I do have that motor and you should be fine on a 6x4 or 6x3 prop. It is seriously powerful, though. Make sure the airframe is up to it because you'll be going over 50mph easily.

Remember, prop pitch governs speed and diameter governs thrust. The biggest prop this motor can handle on 3S is a 6x4.5 or 6x4. That'll give you a lot of speed and I don't think a stock Wing Dragon will handle it. Reinforce it a little or just go with a small prop (5x3 or 5x4). When you have a motor like this you've got enough power to rip your plane apart, but you don't have to use it all.

I say bolt it on and experiment with props, starting small. Find one you like.

Edit: Road Rascal, where do you fly? I see under your username it says "Twin Cities Parkflyers". Is that a club, perchance?

Thanks for the response! I did not know about what the pitch and size affected, that's really good to know. I think that I will try it out.
