Re: Radio controlled airplane

Postby montagdude » Sun Oct 13, 2019 6:16 pm

I've built and flown many airplanes of this size in the past. The key is to make them as light as possible. I will add some 1/32" liteply pieces at the front and back of the spar between the inner four ribs. Since it is so thin, it can be bent across the dihedral/sweep break without dividing it into two pieces. That should be more than enough reinforcement.

I'm not planning to add any type of gyro. Again, keeping it light is key. I also have a micro helicopter that I fly with the camera, without any electronic stabilization except for on the tail, and this will be a piece of cake compared to that. It will require nearly-calm skies, though.

yes, that should help.

All done. If the weather forecast is right, I should be able to do the first flights tomorrow morning.

Is this small battery pack at the left front all what it needs to fly it?
