RE: Flap servo options.
Rob,
Go with the JR, i know that others would argue to the contrary but i would not trust Hitec in my jets and at £80 for the 8711 it does not make sense to go for Hitec. Buy with confidence, fit and forget!
Looking at what the 7955 is going for which is about 60 ish quid, the saving is not really worth it when you compare it to what you would have spent on the airframe and turbine.
