I have the Cmodels MB339 (2x2) and went for all electric retracts/brakes and LADO actuator option. So far only good experience, both in setup and operation. the electrice gear/brake setup, uses just over 100mAh per flight (timer set to 6 min)...which is far less than I expected
Only problem now, is to remember to refill the air system air on my other jets, before each flight. The all electric option is great imo.. (I know it has it´s cons as well....)
