Does anyone have any ideas or how tos to replace (and with what type) the servos on the HobbyZone 3 channel Aerobird? I kinda unexpectedly turned it into an amphibian! (1/2 mile of an irrigation canal) :( It seems as if there must be some type of replacement without having to spring for the entire fusalage ($50.00). Since I'm a beginner any help will be greatly appreciated. Trooper Hook
