BTE Delta Vortex/ Saito 1.00 or OS 91 FX
 

I am going to remove my Jett .90L from my DV and save it for something that is meant to go fast. I have two other engines in my box of engines, a Saito 1.00 and an OS .91FX. I was originally thinking the .91FX but got to thinking the Saito is a bit lighter (helps with less nose weight) and may swing a higher pitch prop like a 12x10 or 13x10. Just looking for opinions on which one might be ya'lls choice between the two.

Thanks

OS 91 and a 12x8 prop with tower muffler or jett stream muffler

OS .91

APC 13x8 works well, a 12x10 might do the trick too.

a 10 " pitch would be to much a 13x7 might even be a better choice for this aircraft. lots of drag in the plane so need lots of thrust lol

This is easy, the OS 91. I wont add to the prop list LOL.
