Oh man I love that MT2 with a big block! Funny thing is that was the other idea I had for the MT2 I converted to brushless. I was bored of the CVR I had in it so I wanted to either go big block or do a brushless conversion and the brushless idea won.
Do you have a 2 speed in that one? I always ran one with the nitro setup and it helped out so much with the topend.
I'd have to run 4S and do some gearing changes to have a chance against yours but I'm a little worried about running 4S to the 1410. I might do some soft runs and monitor the temps to see if it's at least be able to make a few passes but Im really digging just having this one as a basher.
I'm working on a Rustler speed car right now which is getting out of hand, but there's just something fun with the high speed thing.
