Rick,

Thanks for the input. I do have the aileron servos outboard in the wing. It's only the wing mechanical retracts and the flaps that I need to drive from center section servos. Your mods sound pretty extensive. I'm sure the inverted engine and partially hidden pipe cleaned it up a lot. I did take pains to keep the engine opening snug. Just big enough to get the engine and mount out if I need to. This wing center section issue may be the last sticky issue I need to resolve. I did notice on another post that the wing had two servos lined up parallel to the chord line. I'll have to consider that as well. Everything else should be pretty straight forward. BTW.. am playing around with making my own decals. I've made a bunch of varieties, but my AMA number with flag pattern is my favorite.

Why was your Tipo "retired" from active flight?
