6.8-7.0 FDR for 17.5 in a 2wd buggy
8.1-8.5 FDR for 13.5 in 4wd buggy

Timing 45-50 ish

i got the trinity X factor team spec, and it came out of the box with 50 degrees timing seams to much got to gear it like a mod motor its only a 17,5 on a small carpet track doesn't spool up quick enough maybe try 45 timing ?anybody any ideas

I go 6.1 - 6.8 fdr (AE) for a 17.5t o motor on a std. to large track.

How do you guys change the timing of your revtech xfactor? seems like I cannot turn the timing up or down because I cannot lock it down in place due to the ridge design of the timing plate.

I did this and its easy to turn now... thank you so much.

Mine at 53 deg loses its top end.... went back to 49-51 degrees and the torque is back. My sensor board across A,B,C has zero variance.

Mine is the team spec version $114 one (upgraded to ceramic bearings)

Just wondering if it makes a lot of difference if I replace the stock rotor with the certified rotor.... has anybody done this?

51 deg is 5.4A .. I ended up running 50 deg pulling 5A
