It'll go from fast to holey moley that's fast!
Yeah, that's for sure! I don't put a lot of stock in MPH because it's more of a marketing ploy than anything. Not directed to anyone inparticular, having the fastest rig does not equate to having the best or being able to enjoy it the most. I actually took the OS .18 out of my RC10GT because it became such a hassle to keep the wheels down that it wasn't fun to drive anymore, that, and I was spending money on new tires I would rather have spent on RPM arms, a new body and the like. At some point, you will reach the point of diminished returns on installing bigger and bigger mills into your rig. Keep in mind, a bigger mill tends to produce higher amounts of torque, which will eat a drivetrain up quickly. I upgraded the tranny in my 10GT, and while that was never the issue with the .18 in it, hard to steer when the nose is in the air!
I'm merely saying that, I've seen individuals drop massive mills into a 10GT or a Jato, gear them for insane speeds only to promptly drive that rig right into a tree or a parked car, basically obliterating their car.
The .18 is about as big a mill I WOULD PERSONALLY GO WITH (yeah, .21RC10GT puts bigger ones in his, but he also molests Collie's!) before it no longer is fun. You'll like that mill a lot! Very powerful, easy to tune and holds it incredibly! As has been mentioned, toughen up your drivetrain and consider adding some weight to the nose, and you'll have a speedy little machine for sure!
