Hi Martin
The new "how to" is super.
What gear ratio will You suggest for GM 17,5T and Graupner 17,5t for indoor racing, with rubber tires and 2S LiPo.
And how much fixed timing for these motors?
Thanks a lot in advance

Advice on setting up G90
Hi there fellow rc enthusiasts,
Yesterday I have tried to post a message, but it still doesn't show. I think I must have done something wrong? So I will try again;
After reading this forum and keeping track for a couple of weeks now, I’ve purchased a genius 90 speedo. Due to the weather I've only been on the track once and have done about eight charges.I liked it a lot, the increase in speed and punch over the lrp spx that I have been running is just phenomenal.
There are just to things I want your advice on;
As I come off full throttle and go to half throttle the decrease in speed is very drastic, just like an over-exaggerated drag-brake. What can i do to reduce this feeling, other then not coming off throttle....?
Also I was wondering how to get a more linear feeling, now the first half of the throttle range feels pretty much linear. (more or less the same as with my old speedo, although more punch). But the second half and especially the last 3/4, is just like you launch a rocket. I think that unchecking variable timing will do the trick, but don't want to be heating my motor to quick.
The speedo is installed in a T3, together with a GM Pro 13.5T, FDR 5.7
So far I have only been running std mode 6, motor temp ran up to 99C and max rpm recorded =533333. This is recorded over a run of 10min.
Thank you in advance for the advice.

Just fitted new gm motor and its cogging from a stand still. Why would that be? Motor manual says set reserve 6, Where? I see reserved, reserved 1, reserved 2, reserved 4 on telemetry page but no 6!
#1895
Give this a try. Next time out click on 'high speed timing with switching point' and set to 5000rpm
#1896
what would a good starting point for a TRF 416, GM 90 and a LRP v12 13.5 with a 12mm works rotor?
was thinking of starting with about a 6.3 fdr

yeah around 6 sounds good, start on mode 7 and go up from there if safe to do so.

Does anybody know if the new CS Electronic CSX is the same as the GM Genius 75 #97163? Will the GM PC software work with the CS Elec. CSX?
#1899
the gm 75 is now available so why bother with the clone/rebranded CS?

It's cheaper and saves me having to order equipment from two different shops (twice postage costs)!
#1901
now running mode 9, fdr 5.7 LRP X12 Motor temps at around 75-80 and is fast!
now the tweaking begins!

2. for a more linear throttle feeling (as posted in the how-to) untick "variable depence timing"
6.3 sounds allright.
set the speedo according to the stock how-to:
fixed timing 19, max timing 20 (this equals 29/30 with any other motor!!!) as the LRP motors have got 10° MORE hardware timing than gm / graupner / speedpassion motors.
enable the switchpoint (HST with switchpoint) and set it to 5000rpm or it won't start properly
reduce the timing to what is written in the how-to. this will give you a much more consistant performance! and will make it run better in the later half of the run where you can really make up some time!
once again:
THE LRP X12 FEATUERS 40° HARDWARE TIMING EVEN AT THE MINIMUM TIMING SETTING!
THIS IS 10° MORE! THAN ANY OTHER BRAND OF MOTOR USED IN RACING ATM
DO NOT RUN TIMING VALUES ABOVE 20 WITH THIS MOTOR! AS 20 WITH X12 EQUALS 30 WITH REGULAR MOTORS! AND THIS IS AS LOT!!!

mode 7 is definately not save! as it is more timing than you should use with this motor in any case!
this is cause the motor has got a temp sensor and the speedo limits the power! (the motor cannot get any hotter than 80° in any case!)

if you only see up to 10k sw-rpm then you have the software set to =>7.2 fw
click version and set it to >=10.0
then switch point can be set to 5000
