Align TB70 V2 upgrade step by step

[@HeliShed]

v2 upgrade Gabor and all the upgrades that has been required just so that it doesn't fall out of the sky. When are we gonna call this what it is? An early release by align, certainly not ready and needing patching consistently. A shambles. Thumbs up for the effort as usual pal.

12mm motor belt was insufficient, over on Helifreak everyone knew this, even the 15mm belt is smaller than the belts on the SAB and KDS 700 size helis which use 20mm belts.
