its all done up to the point of covering now if you are to do all the mods put the gear closer to the leading edge of the wing cause imne if major nose heavy and use a smaller engin all that power is not needed. as for the elivator i desided not to because on my stock eagle it seemed to have more then anuf behind it to pull of all manovers assuming you set high and low gains. ah and strenghthin the wing at the tips to provent any chance of a wing strike i did it i just didnt post much on the wing.
