Drum spinner battlebot remix

This is a remix of AlexKorvin's drum spinner (thanks!), customised to use an EMAX RS2205 CW motor. It uses the original drum, mirrored. However, simply mirroring the original body did not work for me, as the mounting holes for the CW motor must be rotated by approx. 90 deg. to have the wires oriented the right way.
While at it, I've also widened the rear to have more space for the battery and an on/off switch.
I use a FlySky FS-i6, and a Simonk 30A ESC for the drum motor.

Update (2023): added a stabiliser piece to prevent the bot leaning forwards when the drum is spinning at max speed. One needs to drill a small hole in the main chassis and use a tiny screw to secure the piece in place. Note: mirror print the part for the rhs.

N.B. I use now a Malenki-Nano, and shortened many of the wire connections inside, but the bot still weights ~180g.
