RE: warbird ana or digi servos?
Buy witch ever you can get a better deal on, with that size plane it will not make a difference. I have JR DS821 in almost all my planes and even with my great planes revolver I get about 6-8 good flights off a 1200mah battery and still have good battery life left. I also have the DS821 in my Top Flite Staggerwing, H9 p-47 150.
