Home made RC plane!!! Didnt work so well....

This is a great little video of Jon and myself, attempting to fly the plane we built in a few hours while drunk out of spare parts and packing foam.. Needless to say, it didn't end well

Enjoy!

Looks like you need to drop the control rates way down to begin with...

It's pretty obvious why it didn't fly properly.

You forgot to stick the little CG symbol on the side of the model. All the plans and instructions show one, and you go and forget the most important sticker.

You should always cut them off the plan/instructions, or copy them if you need to retain the plans/instructions in pristine condition like the model.

A good scratch builder will have a draw full of different size CG symbols ranging from the self adhesive ones to the larger four 6mm bolt on ones.
Warning: Beware of the clone CG symbols coming out of China, they are often gray and white, where a true CG symbol is a jet black and white.

You should always carry a few spare ones in your flight box as well, as often the sort of landing shown in the video could dislodge a CG symbol and the plane will never seem to fly correctly again.

As for your 'BSA' plane*, The logic was flawless, the launch impeccable, the flight seem to falter from perhaps a loose nut on the transmitter sticks.

Looks to me like not enough right angle in the motor. Plane seems to be torque rolling to the left.

You know, it actually looks like the kind of accident when people hook the ailerons up backward (such as when they are drunk) and keep trying to save it while actually making it worse. Yeah, check those 'rons.

x3 on airlerions.

Also The tail just looks too close to the main wings, I'm no expert but it seems to me that would make for extremely unstable pitch control.

It depends where you put the CG sticker, some flying wings have the audacity to to not even have a tail, the cowards.

So you're trying to tell me that building a plane from scratch whilst drunk is not advisable?!

Control surfaces were operating in the correct direction. I think we can chock this up to a bad CG.

Maybe it was just because it was so bad looking.



Cheers,

Nah, It's mandatory, that way every thing looks straight during the build.
