After breaking in the motor and running for the first time it was great, then after running it a week later the silicone that is inside the crankshaft blew out. Out of 2000 motors built mine was the 6th one that blew its silicone. Dont get me wrong the motor runs great it is being sent back to Trinity to get worked on and tuned again. The motor is still awesome and runs good! -//- This is a REALLY great motor! It came in great shape and everything worked perfectly. Break-in was a breeze, it was super easy almost easier than other motors that I've seen my friends break-in, no problems what's so ever. Run time on this motor was great atleast 10+ minutes. I can't wait till I can get on the track. A+++++++++ for A Main Hobbies!!!! THANK YOU THANK YOU THANK YOU!
