Are you still racing Serpent 720?
I am thinking to pick up a MTX4 as a used roller.
The Serpent i bought it used, and did not use it much as the clutch bell keep sliding out; so i put a flange bearing to prevent it from happening! I do not see this is a permanent fix; well we will see. A local 1/8 nitro guy taught me to do so as he said some 1/8 are using this method, too.
Are you guys still racing the 720, what do you think in regards to the overall 720 performance? Thanks
