Love this airframe.Bought it as a kit this time. Decided to make another one (#3), but this time a little more visible color scheme. AD 4B model from China Lake Naval Ordinance Training Station (NOTS) seems to fit the bill. I used Dymond D90 digital servos for ailerons(which turned out to be overkill) and Hitec m65 on the rudder, and elevator. Bomb drop of course is mandatory and is an Adam Bomb
http://dropadambomb.com/mechanism teamed with Dymond 3.7 gram servos. ESC is a Eflite Pro 40 and motor is a Durafly 850kv Stuka motor flown on 3s. I used one of my RC Custom prop adapters on a 12x6 two blade prop which proved on my Stuka to be the perfect combination. This plane is faster then my stock powered 750kv Skyraider on a 12x8 prop. I have also added metal trunnions from PW-RC and they have made the gear very reliable. This is my go to plane. I don't know how many flights (hundreds) are on her, but the wings are actually showing some stress cracks now.
