Maby I'm overt thinking this one but I just put in new rivets(3.1,4.5) and also a Bender 51/43 heli. Everything works great when it's cold but after a few hundred yards the primary gets way too hot and belt slips. Secondary seems to be cool. Would the secondary spring not being set right cause this? What's your thoughts guys.
Everything was working fine before I started tearing it apart.
