True... That one guy ha da 7700kv motor on 4s, so I think it should stand up to a few runs up and down the street. Unless he is really lucky and I'm really unlucky I think I'll be ok for a few runs.

The 5700 castle motor on 3s in a 1/10th TC will be plenty, I get 60mph no problem, gearing up will get you even more. If you really want 4s, just use the castle 4600 motor, 80 should be no problem for that set up. But as other said, a 1/8th scale would be a better bet. Once I started getting my TC up to 60, finding any asphalt smooth enough becomes a problem. The 1/8th stuff can handle a bit rougher terrain (most asphalt around here).

Metallover, I'm definately in the speed lovin group

Wander over to isc.com & have a look at Nic Case's thread about setting up for 100mph. He explains a lot of what you're asking

I intend to use a MM/7700 combo I got from linc in my TC5 & will start with 2S & work my way toward 4S. Mods will be required to allow things to fit & I will run 32p (with bore reducer if I have too!!) but there are gear manufacturers outside of RC who I hope will produce 1/8 bore...again lots of links at ISC

The body you use will also determine how your setup handles, I have 3 HPI (2 x 190 & 1 x 200) waiting for trials & I hope the 7733 Stiletto with some vertical stabilizers will work best of the 3...?

have you got all your electrics e.t.c yet?
i am thinking of making a speed car out of my tc4 i was trying to work out what kind of speeds it could acheive e.t.c with the speed calculator but i didn't what values to put in for the 1st 3 boxes
i was planning on using a tekin 6200kv motor on 5s with a mamba monster speed controller
have you decided on a voltage e.t.c yet?
