I've got an Aerobird and now want to get the GWS Tiger Moth. I've heard that it's worth going striaight for the 4ch rather than getting 3ch now, and 4ch later. I was wondering if there was anyone who has had one before and could list ALL the things that I will need to get it flying. How many servos, what size, what type of ESC, carger & how big batteries can be (I've heard of 30mins+ flight times and that is what I really want). I have two servos from a futaba attack 2ch set (they're about 4cm x 4cm x 2cm, not including the servo horn) could I use these? Money is a big issue for me so I want to be able to shop around, knowing exactly what I need.
