In regards to the retracts, the ONLY place the TT p/n appears is on the BOX LABEL ! No reference is made in the manual. Just a heads up. Not an issue for me.

Looking at the wing gear mounting struture, I believe that ANY good mech. gear can be fitted.

One of the really cool offerings from TT is their Pitts like muffler that has a pair of exhaust tubes that exit the Exhasuts stack areas already exisitng in the fuselage ! pic's attached.

Won't work for me with the FX-1.60 install but will use some sort of Pitts type muff.

More later.
