... The motors when set up correctly run great. if you have any setup questions you can go to the YS page on RCU and Troy will be glad to help. He knows the engines inside and out and can help with any weird setup questions you might have. Follow his setup and you can't go wrong,
You might need to call YS parts and service for questions going forward, according to Troy's thread [link=http://www.rcuniverse.com/forum/m_7552701/tm.htm]here[/link], he has no more time to help supporting this space in the future.
