hi, i just bought a yard bee , my first ele. plane. i`m not reallly impressed w/ the power or speed or it. it doesn`t climb well , but i did manage a loop w/ it.what can i do to get more out of it?? it has a stock 280 motor, 5 amp speed controller,7.2 v 600mah battery, 7.5 x 5 prop. i know it should have a 800 mah battery but that will only increase flight time? i have a 7 x 6 prop i`m going to try but i don`t think that`ll help & maybe hurt performance. should i just put a .061 glow engine on it? i`d like to keep it electric, but not spend $100 to make it faster. thanks guys, conk
