Which air retracks best fits this model and thinking a 180 four stroke ?

Standard 9-12lb sized air retracts will work just fine.

The problem is with the bend in the strut... you may want to look for struts for other Texans, etc.


The ideal situation is to shoot for retracts for a model heavier than yours... e.g. a 14lb model, so that the retracts are more "robust".

I regularly apply thin epoxy and install tri-stock extensions to spread out the torsional forces on the gear mount areas. I suggest you do likewise.

The plane is rated for a 2C 1.60, so a 4 stroke 1.80 will work, but it will be fairly scale like... e.g. no unlimited verticals.

A 2 stroke 1.60 would be closer to the performance of a 4 stroke 2.20.

My four stroke Magnum 1.80's are closer to say a two stroke 1.40, or a 26-30cc gas engine, in terms of performance/thrust.

I'm not well versed in retracts or 4 strokers, but I'm flying my CMP AT-6 at just over 15 pounds on an O.S 1.20 with a 16x8 two-blade prop. Not a screamer by any means, but good, solid control with enough power to do what you need to do with a WWII trainer. Hope this helps!

Probably should have been a little more specific. That's an O.S. 1.20AX two stroke with a 16x8 prop. Apologies.
