Tekin are coming out with a new series of Redline motors soon. I have a Redline that i've had for 2 years. That's the time it's taken most other companies to come out with 3 generations of motors, and the Tekin is only just starting to fall off in comparison.
I have a Duo3 in the post to compare, but I doubt it will have much trouble out-performing the 2 year old Tekin. The new ones will be another story.....

My car just hit 88mph. I hope it comes back soon....
