I think I will try the Tiger moth.
GOOD CHOICE!!!!!
For Battery's I'm geting about 10 min full throttle on 300Mah Nimh packs.
Forget about the 150mah GWS Recommends.
Guys are also getting 20-30min on Lion batteries Ezone had some great threads describing how to make them from certian cell phone batteries also they had some good places to buy them pre-made.
There are some mods that I would reccommend
Use dental floss or thread to create flying wires for added strength or add some carbon fiber to the underside of the bottom wing to strengthen it.
