Rear Loading Battery Cage on V400D02
I did'nt like that you had to take off the canopy every time you want to change a battery. It is very time consuming when you really just want to be up in air. With the Metal Tail Boom Support from RTF-Heil, it makes it possible to swap batteries from the rear and not have to touch the canopy.
I also moved the ESC to allow the use of bigger battery packs, but is also better balances the heli as well.
