Jon:

I'd quit fighting the urge to save a buck, buying multiple engines that just do not do "it" and buy a Jett 60 LX. God I love this engine. Have you ever seen someone hover a race plane? Come on up> ENJOY Bro 119.

I have 2 OS.91s one on a Cermark F-16 and one on a Juno F-18. Both have Ultrathrust Mufflers and I use APC 12x8s. 15x8 is way too much prop for a short stroke engine like the Mag .91 and a speed plane.
