Yeah . I found my max today and ran a tank on the ground. My idle to WOT was smooth so i took her up and had a blast. I let her cool off for 20 minutes. Flew her for another 10. Let her cool off for 30. Flew for another 12. She was beautiful. Starts up with a flip or two now. Don't freak out about new motors. Just run them 6-8 click rich of max lean, and you'll be fine. Just look for a consistent exaugst and you won't burn out your motor.
