This might be a really dumb question but, the Manuel recommends breaking the engine in on the plane and in the air.
Why so much time breaking it in on a stand?
Not a dumb question at all.

Two reasons for me.
First :I've always performed the break-in process for engines; glow and gassers on the ground ,even if the manual states it can be done in the air. If the engine is going to give me fits I'd rather it do it on the ground than in the air. After burning enough tanks were it seems to run reliably then I'll fly it and continue the break-in process where with this particular engine it will take a while.
Second: There is 8-10 inches on snow here and when I maiden the plane I don't want the engine to quit where I have to dead-stick out in the lower 40 and schlep through all of that snow to fetch it !
