RE: h9 p40 and 91 4stroke.
I agree. I have the OS 91 in mine w/o the fuel pump and it is way more than scale power. Another plus is if you keep your engine reasonable, the plane will be lighter and will be much more enjoyable to fly. I.E. easy 3 point landings.

just finished mine with a 91fs used a 90 deg close pipe to a 45 deg. stock section and silicone exhaust deflector to exit the rear of the cowl no muffler out the side here the cowl looks to good to cut out a hole other than for the needle. its raining like crazy in San Francisco so haven't test flown her yet can't wait.the gear was a bit of a pain in the a@#$ it takes a bit of tweeking to get it just right
