RE: Best engine
Windcosmic;
If you have to worry about money and prices, stay out of the game until you can afford the Nelsons and other $400.00 engines. You can't compete with the high dollar guys. You can fly the OS or other sport engines with a home built Viper and learn what goes along the way and not break the bank. Become a super pilot and learn how to set up a bird correctly from the fast guys, and ENJOY. MHO
