I am in the same situation. I have the WH Sukhoi on order. I just bought a DX7 to go into it and I am using 5955tg servos 1 per aileron, 1 per elevator half and 1 per rudder. I am also worried about the high power draw that I have heard about. I am thinking of fromeco electronics and batteries and using the deans connectors. My biggest question is using the deans connectors, you still have a standard servo connection between the batteries and rx right? Smart fly is supposed to be working on a 50cc size power expander..... Needed? Not needed? I lost an H9 Sukhoi due to to many flights on a weak battery.... Thought it had more power than it actually did. I had flown it 6 times the day of the crash, asked a better pilot that flys more aggressively than I do and think we hit a low voltage dropout/overheated regulator. Don't wanna go that route again. Suggestions welcome.
