OK, as nobody else has replied yet, I will.
I have never used a Hacker A200, so I can't comment on that particular motor.
But I use a Plettenberg Predator 37/6 in a 3.2 meter (126") wingspan own designed IMAC model.
Equipment used is Jeti SPIN 300 ESC, 12s batteries. Engel 30x14 or 30x16 propeller at about 6000 rpm.
Initially flew with 12s18Ah (3x6Ah Turnigy Nano-Tech) at 18.5 kg (40.7 lbs) flying weight. Performance was good but battery capacity marginal for two large IMAC Advanced sequences. (Old packs nearing the end of their service life.)
Later changed to 12s24Ah (3x8Ah Turnigy Nano-Tech) at 19.7 kg (43.3 lbs) flying weight. Excellent performance and plenty capacity for IMAC Advanced.
Electrics definitely works for large scale aerobatics, particularly if the airframe itself is light weight.
Good charging equipment is mandatory, though.
Regards,
Magne
