Hi Pete,
Ditto the welcome. I have let many friends sit in my Four and HR2 over the years, the largest of which was
6'5" and 225. Realize the sitting height in the RV4 is directly proportional to the seat cushion thickness. Sitting height varies by the individual as well. The bigger the pilot, the thinner the cushions to clear the canopy when lowered. My friend (and former Van's Engineer) KK is your size exactly and flies a nice 160HP RV4 every day. My F16 bro Tron is your height and fits fine in his RV4 that has a cool seat back modification allowing him the "F16 recline" in his RV4. Needless to say, where there's a will...
Several things help:
1. Thin lower cushion. Thin rear cushion. 1" NASA foam on both worked for the 6'5" dude.
2. Lighter/smaller shoes (I like NB minimalist)

3. Move seat aft by attaching a second hinge point aft of plans.Does change back angle to more upright.
3. Switch to a Clarity aloft or other non-overhead head set.
All that said, I have a friend in Owensboro with a nice 4 that might be able to hook up with you, I'll email him.
