7300 rpms with an 18 x 8 is approximately 18 lbs. of thrust according to PE Reivers prop chart, and probably around 65 mph or more level airspeed.

My usual recommendation for any gas engine plane is nothing less than 1000 square inch wing; for sure not less than 900 squares if you are experienced and it is an aerobatic plane with a farily light gas engine. For a Homelite I would stay at 1000 squares or above due to its weight.
