Got a quick battery question for you experts. Im currently working on converting one of those $15 guillows balsa kits meant for rubber flight into an rc plane using a gws pico flight pack. Anywho, its a fairly small plane with 24 in wingspan and a full fuselodge (not a stick). My question is, would there be any problem using a 6 cell 7.2 volt 900mAh battery in this little guy? Im guessing that would put me in flight for over an hour, its the same battery pack used in aerobird challenger, is there any obvious problems with using this battery? I saw some people who built a similar sized plane use a 6 cell 7.2 volt 230mAh battery in theirs, same battery setup, except its 670mAh less than the one I'd like to use. Any problems with using this battery in a smaller balsa plane?

The biggest issue with the 6-cell, 900mAh NiMH pack is weight. It is about 4oz.

Consider a 2-cell [link=http://www.hobby-lobby.com/thunderpower.htm]Thunderpower[/link] 860mAh pack that can deliver 8.5amps continuous and up to 13amps burst at only 1.5oz.

A 2.5oz weight reduction in your small plane makes a huge performance upgrade!

What motor/prop/gearbox will you be using?
