IMO OPS Motors are the best motors you can buy. This is my second one and the first one was sick fast and lasted for ever. They are a little funny to tune but once you figure they like to run a little lean on the bottom your set. Check out the OPS RADICAL thread there is some good info in it. I dont know any one that has run the new OPS/RADICAL Motors who wont tell you they are one fast motor. Good luck

fast to the point of undriveable from what i have seen of them . most refer to them as light switches :nod: they run cool and make a buttload of power for sure :nod: i am not knockin' the engine by any means but they really dont have a useable power , you give it gas and it goes :D

Light switch power ummm no there power band is very smooth. They run cool with very good fuel mileage. I get over 10 mins of run time with my Hellfire with radical 621T. My RC8 gets around 8 1/2mins

I know someone who'll sell it to me for like 130 or so, but I don't have a kit, or anything.
