Yes, I think its possible to use in a CARF Mustang.
Three Blade shure. - with the 1:1,6 ratio
Four Blade - with 1:1,6 - I don't think so - the three Blade is a 26 x 20" - so you'll have to use a 24" 22-24 4 Blade ... -probably this small diameter looks silly on that machine.
maybe with a ratio of 1:1,8 or 1:2 . . . ?
-a ME 109 was flying with that 1:1,6 youi se above. The pilot says: half throttle is enough - the full throttle is for fun! - But it is damaged in a start run by a pilot -mistake.

The price is 800 Euro.
The BFM 80 must be here at Heger Technik to modify the housing for the Gear-bracket.
