The plane is big and as you said power is way more than enough..... but......Do you think you would consider a can or pipe later on?
Would you have enough ground clearance for a 28 inch prop?
Those control surfaces are so huge just imagine the thrust vectoring that could be had at lower rpm's with a large diameter prop.
I will NEVER do a pipe, just does not fit my flying style and I can't stand the "jump" in the middle when doing low and slow 3D. No need for a canister anywhere I fly so it just costs too much money for a changed exhaust tone. It will need a 28x9 prop after I get a couple gallons through it. I understand they are ripping a 28x9.5 even at elevation. I will have clearance, but I will likely change out the gear regardless, it is nice gear but I don't see it taking lots of harrier landings with an extra pound on the nose.
