Hello!
Is copying modes reversible? I think I have by mistake in my old Genius 95 copied mode 4 to mode 5 with pc What can I do? Software 0.9.

I believe the only way to reverse is doing a factory reset.
Check manual on how to do it.

9.5/10.5 T motors

they are designed to meet efra regulations -> changed magnet + the 9.5T features a fan on the magnet to bring down temps

the 9.5 is between the blue sport 9.5 and the purple sport 9.5T in matters of feeling and power

the 10.5 seems to be pretty good but i have not tested that one myself


regarding the reversibility of the mode changes, please do a factory reset -> have a look into the manual how to

Default Graupne sport 9,5

Martin is there any other differences between the blue and purpla 9,5 motors beside the different rotor sizes... blue 12mm purple 12,5mm

the reason is that i denmark in the series we run only the Graupner blue is allowed in 9,5 and not the GM purple... you are allowed hower to change the rotor?

the same goes for 13,5 where it is only the red graupner version allowed, but it allready has the 12,5mm rotor, so i guess it is the optimal motor from gm so far..

So it's efficiency and temperatures are not very similar to Evo3 and Pro series? There are quite a lot of old dr speed motors in our shops whith old, low prices, but I'm not sure if one should not pay extra and buy Pro with Evo3 rotor(because of fan)?

Look back a few pages. Martin has posted his setups for speedo and which programs he runs for what...

program 8 i think is not suitable for a touring car regardless of gearing

i use program 6 and 3 for stock racing with 5 cells and offroad with lipo.

but again take 5 mins and read through the earlier pages.. it's all there for you

Hi Anibal,
Here you have some important information given by M. Hofer:

Stock racing HOW-TO

firmware 0.x

Most likely you will want to use mode number 6 with the following important values:

amplimit: 200 - 250

brakemin: 5%

brakemax and fullbrake should be set to the same value! (I use 95%)

frequency: #3 (16kc'/adj. current..)

reserved: 22 (new brake software feels a lot nicer)

maxreverse: 100

softstart: 50

powercurve: linear

auto throttle / brake: 0

timing w/o sensors: 30°
timing with sensors: 30°

voltage cut-off: 3.6V


firmware 4.x

amount of timing
least: mode 6/7, mode 3, mode 8 :most

even though all modes are programmed with timing set to 30/+30


mode 6/7 should be programmed as mentioned above

mode 8 has A LOT of timing an thus huge amounts of RPM

BUT most motors drop of after 3 laps or even less when using this mode, so be careful!

mode 3 is originally a modified mode
to make it Stock-ready do the following:

- pick mode 8 via transmitter

- read out the esc data with the PC-software (v1.1.5 or higher required)

- go to advanced settings

- pick mode 3 in the "controler mode" flipdown

There will be a window showing up saying: sure you want to copy the
background information?

click "yes",
then klick "no" when it asks you if you want to set the standard values
finally click ok as you know you will use the same batteries as before :-)

- send data to the esc

- read out the data once again

- read through the log-window (just received data of course) and check if
value 33, activediodemaxtime is now set to 110 (original value is 50)

if you successfully set the new value: congratulations

if you still have the value set to 50, simply try again



Some general information:

Brushless is opposite to brushed:

less frequency = softer, less precision and power
more frequency = more punch/precision

I usually use 8kc, but or stockracing 16kc sometimes gives you just the little extra bit :-)

I personally always use mode 6 or 3
mode 8 is too much for 9.5T racing

5cell with 9.5T GM Purple motor geared to 5.1 - 5.6 on any track (indoor carpet of course, as it's the indoor season right now) using mode 6

for mode 3, multiply your gearing with 1.2!

i.e mode 6 gearing = 5.1
mode 3 gearing = 6.1

of course all stock modes require sensor wires to make use of the software timing



the speedpassion motor can be geared pretty similar to the gm purple

gm blue need to be geared around 0.2 shorter

lrp 9.5 needs to be geared around 1.1 shorter

cs 9.5T needs the motortiming to be turned clockwise to nearly middle of the c-solder tab

I hope this helps all them stockracers out there to do it like me and my teammates do :-) rule the straightaway and try to not lose too much in the infield *g*

one more VERY IMPORTANT thing:

you can see your transmitter values in the "advanced settings"

fulltrottle should be around 1.9xxx ms
neutral around 1.4xxx ms
fullbrake around 1.1xxx ms

if your values are far off, you need to do a new transmitter setup!

and use the transmitter to switch between modes, not the pc software if not specificly mentioned (like above)
otherwise you'll copy program data from one mode to another
Anyway, some careful with the chose ratio should be take. Otherwise, you may notice some “Ampere” smelling from motor…

Thumbs up

Thanks Miguel
I will try 3 and 6 mode, i think it is the most friendly for the motor.
