LRP Vector x12 Brushless Motors
#197
Guys,
does anyone know the diameter of the rotors on the x12?
I ask as Tamiya are bringing out 12mm rotor versions of their x12 (the current one's part 42125 etc are x12 aren't they?) but I can't find anywhere what the older motors had in, and therefore the difference in performance etc!?
I assume whatever a standard x12 is would also be the old Tamiya diameter!

@radwerx: kV rating is not affected too much by sensor timing, therefore we don't give different ratings for different timings. So you can go with 7100kV for 5.0t at -10° (oooo insert) as well.
@DaveG28: standard in all X12 motors is 12.5mm rotor, Tamiya specially requested a 12.0mm rotor in their new motors but ourselves we stick to 12.5mm as we feel this is the best allrounder!
We do offer optional rotors in 12.0mm and 13.0mm too, you found all part numbers at www.lrp.cc

@DaveG28: actually these questions you should ask Tamiya as it's their motor...
Generally speaking, a smaller rotor improves driveability (smoother) and gives more topend but the downside is slighly lower efficiency and less torque. Temperature isn't much different.

Will you recommend simply gearing higher (lower FDR) to gain top end speed then? 'Cos I am running an FDR of 7.0 currently on a relatively large track and the car still doesn't fast enough on the straights. Given the history of the X-12 i am worried about gearing any higher.

Dont be afraid to let them get a little hotter too. THey dont mind the heat!

I have dyno'd the 17.5 and 13.5 Friday and ran both today in TC. I found that even with the -10 block in them they dyno WAY better than any Duo or Duo2 motor Ive ever dyno'd on everything except EFF. They are about 2-3 points lower on eff than the others. Other than that they blow away the others currently available. They are closest on the -10 setting to the Duo based motors. I ran today with the -5 and 0 plug. I think they were best with the -5.

I got a chance to run them in *coughdirtcough*, but they were incredibly fast even without any timing assistance.
Interestngly, the instructions for the motor do not recommend using profiles 7 & 8!
There is also a set-up on the AE site from Mr. Cochran using the 13.5 with a pretty high FDR on profile 6 (FDR 6.3 IIRC).
