Gearing for an Evo IV

Gearing for an Evo IV
I just got a Tamiya TB Evo IV with a GT7 esc, matched Fusion GP3300 cells and an Orion Revolution V2 12x1 motor. I was wondering if anyone has used the V2's and what they think of them and also if they can offer some gearing advise.

5.7 to 6.0 should work with a V2 12x1.

You should start gearing at about 7.8 to 1 ratio and adjust from there based on your track size. A ratio of 6 or less would most probably fry your motor.

Depends on the track. If it is a huge track that sort of gearing would work. I've run an 8x1 V2 at 4.5 on an oval track and the motor looked fine after a 4 min run.

Use about 2 teeth less on your pinion than with a normal 12x2. Gearing really depends on the track. Example : this week end at the BRCA nats, I can predict most people will go for a gearing about 6.2 on the V2's, because the halifax track has a 200m straight.

I drive on a large track, 19 s laps, so my recommendation was based on that. And the motor holds up great with that ratio, 10-15 runs before you have to do anything with it.
Of course, a smaller track needs a differant ratio.

At the Tamiya track or a track similar to the Nats track in Portland, I would start gearing a 12x1 somewhere between 7.1-7.5

stock gearing
what would you guys suggest for an evo 4 running a silver can in stock? I bought the 72t tamiya spur looking to run a 45 tooth pinion with it but there isnt enough adjustment in the motor mount to reach the spur, 72, 45 works really well on the evo 3, obviously not on the 4
thanks
