I don't remember how much I cut off but probably somewhere between a half an inch to an inch.

I don't know about the engine running hot but Friday was it's maiden and I flew it twice. Today I flew it eight times.

Never a burp or hiccup. The DA ran just fine. Took about 10 seconds to clean so I guess the stacks are long enough to exit the exhaust off the plane.

I guess I am just lucky.
