I appreciate the view on the DEPS, I will see when I get to that point and I may just engineer something myself.   I like the idea of an arrow shaft, and it is classic.  Would I be correct in my thinking that a side mounted elevator servo would eliminate the differential?? 

 Here's one to all of you who may be looking to thin out your engine collection.  As I said I have an OS RE engine, and I am considering using it in the Tipo.  Well, that was before I came across Carolina Custom Aircraft selling the T2A MkII which really needs an RE.  My point is, if anyone as a Webra or a YS 2 stroke that they don't mind getting rid of and one which will go to someone who truly appreciates it let me know.
