Little more work tonight. Designed a 3D printed battery tray with some brackets so I can use a strap plus velcro and the velcro is then glued onto the plastic so it shouldn't peel off.
Also decided against using the back wheel setup just so there is no force on the rudder when I land softly so I added a little extra foam as the skid.
Then for the landing gear another 3D printed piece which will sit flush to the bottom of the plane, the wheel setup is a spring loaded friction fit and even in a crash won't come out
And here she sits on her new legs, getting close to be maidened, I think I will paint it after it flies.
