Corally motors are ballistic straight from the packet but in my experience can let rip without warning. Im not a big fan of trinity motors anymore, they used to be all i used but the last 3 i had were very inconsistent. The epic based motors used by tuners such as brood are a big improvement. Have you looked at one of the team almighty Jimmy Maddison motors? Jimmy works at Almighty as a motor tuner as well as a factory driver and I run the 19 turn version - jimmy builds awesome motors! Just my $0.2 so nobody flame me!
