I will stick to Nicads for now just for the sake of saving money (my ulty has used most of it). I think i will have to go bigger. my voltwatch goes to the yellow when i move all the control surfaces, so it cant handle the current. Phew, good thing i didnt fly this. Thanks for all your help. Do you think 1100mah is big enough its almost double, but i may go bigger just to be safe.
