GM Genius 75 ESC
Schumacher have announced the release of the new GM Genius 75 ESC. This hotly anticipated speedo has already won the EFRA 1/12th Euro’s earlier in the year. Especially designed for smaller applications such as 1/12th pan cars, it is equally at home in Touring Cars with stock 9.5T motors and above (2S LiPo) 3.5T (1S LiPo).
Features:
- Cooler operating temperature due to complete, light aluminium housing and special PCB design with extra-thick copper wires and optimized switching flanks. The flat design provides an extremely low centre of gravity.
- Top efficiency thanks to the new, even faster 16-bit processor and optimized software with newer, simpler operating software; providing longer operating time and greater performance
- For brushless motors (see operating voltage) and motors with brushes (up to 7.4V)
- Telemetry functions
- Automatic Hall sensor detection
- Storage/read-out of max rpms, maximum current, and temperature
- New brake and power programmes
- 10 user-programmable modes
- User-updatable firmware
- Soldering socket for easy replacement of wires
Specification:
- Recommended motors: >= 9,5T (with 3,7V >=3.5T)
- Excess temperature protection:
- Weight incl. leads: 85 g
- Weight excl. leads: 50 g
- Cell count, Pb: 3 – 6
- R DS on der FETs bei 25°C: 0.0008 Ohm W
- BEC : 5,8 / kurzz. 4 V/A
- Pulse frequency: 0,25 / 0,5 / 1 / 2 / 4 / 8 / 16 / 32 kHz
- BEC max. power loss: 2,5 W
- Voltage drop @20 A: 0,017 V
- Continuous current at 25 C: 75 A
- Cell count, LiPo, Lilo: 1-2-3
- Cell count NiCd, NiMH: 4 – 10
- Dimensions (LxWxH): 34 x 31 x 18 mm
- Operating voltages: 4,8 … 12 (3,7V with rx)
Programmable functions:
- On/off function with button
- Low-voltage cutoff
- Automatically adjustable for Li-/Ni batteries on in 0.1-V steps
- Automatic brake, minimum brake, maximum brake, full brake, ABS braking function
- Maximum reverse; various reverse modes
- Automatic throttle
- Soft start, soft braking
- Current limiting, start-current limiting, turbo
- Transmitter lever positions: full throttle point, zero point, full braking point, zero point width
- Timing, variable timing functions
- 16 power curves for 3T – 21.5T
- Settings for temperature shutoff, sensor mode, braking mode, motor type
- Frequency 0.25 – 32 kHz
- For other functions, see PC software.

A shame that this speedo still needs a receiver battery for 1S

But there is no problem with this :)
You can use booster or rx battery, but main thing:
IT WORKS!
I tested gm 90 with 13.5T/1S lipo and ;) what to say …
is only too big for E12 :)

…but is it as fast as the Black Diamond, or the Tekin?

The result at the 2010 1/12 stock Euros would appear to suggest yes…

heh :)
old GM 95 with X11/13.5T and 1S can do up to 46krpm
when my F1 car was on table, the same gearing and only
new one GM :) and 62krpm. On old one after race I charged
my 1S about 1500mAh, and on new one ~ 2500mAh.
It is big difference, it is really good speedo, if set right,
you don’t feel WHEN and HOW it switch to high revs :)
At race time, when I use my old one, I reach max speed and I
can’t do nothing to 13.5T/2S lipo/F1car, when I switch to V2,
same gearng, battery, tires, on stright ;) it was fast like 13.5T/2S.
But remember, when use rx batt or booster, set switch to OFF.
Regards and good luck!
