Evfast,
No matter what airplane you buy get a good 50 gas engine. BME, ZDZ, or DA. Light weight and awsome power leaves you many choces of airplanes to use them in (wish there were even more) Don't even consider a 40. Not worth it when you consider the 50's available weigh the same and cost pennies more. The Patty is the best looking airplane I own. I wish I could build that good but even if I could there is no way I could have bought a kit this big, built it myself and paid less than the $379.00 I paid for my Patty. That includes shipping from Chief Aircraft. Mine has the fiberglass wing tubes also. Very sweet!! The performance with my BME 50 is awsome. I only use a 21X8 Airwild prop and you woulnd't believe the vertical performance. I may switch to a 22X8 prop in the future but I really don't need it to go straight up any faster than it does right now. Good luck with your choice.
