TRX-4 vs SCX10 gearing help.
 

I've forever ran a 56t spur / 10t pinion on my SCX10's. I'm working on a new TRX-4 build and would like to run whatever is comparable? I have a single speed TRX-4.

What size spur and pinion should I run that would give me the same speed?

Thank you in advance. "thumbsup"

SCX10 or SCX10II?

56/10 on a SCX10 would be about 42.5:1 which would be between a 16T and 17T pinion with the 45T spur and a single speed on a TRX4.

56/10 on a SCX10II would be about 54.6:1 which would be a 13T pinion with the 45T spur and a single speed on a TRX4.

I'm not sure. I've ran a Toyzuki V2 for the last two years. So I'd say SCX10 II.

I'll grab a set of pinions and a 45T spur. Thank you!

I'm running 13/45 on my Sport with stock motor and 1080esc. Great crawling set up. Decent trail speed - fast walking pace.

Likely a SCX10II then, 45/13 would be a near identical ratio for the TRX4.

The 45T spur is the stock one for all models but the Sport so you likely have the right spur if you have a TRX4 trans.

Mind sharing what turn motor you run?

Thanks.

That's correct. Mine was TRX-4 Tactical edition and I've since converted to a single speed.

The Sport manual has all the gear ratios and FDR's on page 27....since it has the single speed, should have all the info you need. Basically (spur/pinion)*15.8 ...Comes in handy...
