I don't know what your experience level is, but for me, I'd have a good pilot on hand to get it down if needed.

Your stall speed is going to be much higher, so keep that in mind and land fast. With that motor and prop, I'll bet getting in the air won't be a problem. Dedicate your first flight to trimming then plan for the landing. See what and how fast the plane acts like when you drop your speed.

Make sure you've got plenty of roll out room after the plane touches down. I'll bet that bird is gonna come in fast!

Just an idea: Y'know it wouldn't really be THAT hard to add another 6-8" to the wingspan if you had too......... just a thought. Do some calculations and see how much it'd help.

Besides, anything will fly with enough power. Fighter jets are proof of that.
