Just thought I'd give this an update.
I finally ordered the parts about 2 weeks ago (my gf's anni gift for me) and finally put it together today.
Everything is almost good. I got it up in the air, but the rudder has a lot of slop. I think i can fix it but double-ing up the bearings.
also need to fix the vibrations. or learn to better tune the gyro.
But the idea works. it's super cheap and it works great. The most expensive part of the project is the servo holder, and the tail fin holder which is holding up the motor.
