Funny my DA 50 swings a 22x8 at 7000 or more I think. The FPE 3.2 will pull harder than a Brison 3.2 IMHO as I have flown both in the same airframe.

I would always go with a lighter engine overall. I think the DA 50 or ZDZ 50 are great. I also think the FPE 3.2 and the DA 50 seem about equal as far as power and transition. I used the same 5925 servo also for my throttle.
