How fast is a TC with a .21

[Monster19]

Does anybody know relatively how fast a Terra crusher will go with an Hyper ofna .21 engine and what is the diffrence between a OS . 21 RG-X ?

Also, Today someone told me they JUST released a 3 speed transmission for the terra crusher.. has anybody here heard about it yet and if you did... where can i get it

OK i have the crusher with the hyper,was very happy with it stock gearing it would fly.Hit good wheelies with a little help.The os is in my maxx.I,m experienceing popping sound from my hyper.If i can not find the problem quick os here i come.Had no problems with my maxx even seen 325 temps and still runs strong,23/72 gearing and pulls wheelies from a dead start.But the crusher is my favorite.People love to see this big truck run.Where did you get info on that 3speed please let me know.

I'll let you know.. 2 other guys with crushers told me it JUST got released very recently..so it will still be a while till we see it.. but it sounds insane..
We will be killing mad forces with a 3 speed tranny and a .21 OS :)
