Spoken like a true pro. I guess I shouldnt talk though, I spent a bunch of money to have my plane pimped out by Tony. Well it will sure look nice though.

I would think one 4 cell lion would be fine for hard 3D. I only say this as I have flown dozens of flights on 28% planes using one 4 Cell lion pack and 6 digi servos with no problems. I am talking about from take off until landing nothing but rollers, walls, slow knife edge flight. Oh yeah that was also with no power expander and a really small PCM RX.

If you wanna save weight with the ignition setup get that trick built in reg switch from Duralite. I just wonder if it will put a load on the battery when off.
