The Big Red .28 has insane torque, as seen in the video... on pavement it is uncontrollable... I know that because that Revo is mine
I am sure the LRP is a very good engine, but I don't see where the extra $55 go for. I don't see why you would need more power...
In the video I removed the shim, put a hot plug, and run on a 5% nitro fuel. I can't imagine what it would be like with a 30%
