Read Toni Clarks site on ignitions.......I have a G20 and use a 3cell NiMH pack. It is 1600mah and I get 5-6 10min. flights and only put back about 3-400mah. Can't complain with that. The secret is the cell count-if you haven't read his info you are sorely missing out!!!!!

BTW, I like the mag. G26 better-simpler
