Pro Master I and Pro Master II are different hardwarewise. I donīt remember exactly but I think the Pro Master I had a limit of 10 turn (brushed) and the II could go below this. I think the II had a sticker on the backplate.
My own dyno is a version I but anyway I didnīt test a motor below 11 turn.

Jev,
Have you done any more pulls? I'm just waiting on a PS for my TD45 to start work. So far I have a GTB, GTBSS, XBR and Super Sport with Novak 4.5, 6.5, 7.5, 8.5, 10.5, 13.5 and 17.5 to work with. I've also got several different rotors and an LCR meter to work with so hopefully I can find something interesting.

GTB vs GTBSS will be interesting. Also power/rpm vs magnetic strengh by using the gauss meter
.On thing I will probably be is testing is 13.5 motors with sensorless esc's. There is a new stock brushless class for the bikes and a lot of racers want to run sensorless esc's.
Why can you not use a large 12v lead acid battery to run the dyno? That is what I use.
I was thinking that for the lower winds it would be best to drop down to around 4v, then would still be able to test the whole rev range without fraging the rotor.

Thanks for posting this! I was beginning to think my TD45 is a big paperweight!

Anyone have any idea about a correct inertia setting for the flywheel?
ProMaster II software is windows based. (needs to be bought)
The other version (ProMaster I if you will) is Dos based and free.
Indeed there was a hardware change for the Robi with regards to brushed mod motorlimit like stated before.

Hey JevUK,
I just bought a Robi as well as a TurboDyno 45 just for testing Brushless stuff so once I get setup I can start posting stuff. I have a couple questions for you on the Robi. First, were there two versions the Pro-Master and Pro-Master II? And if so do you know if I can still get recalibrations or upgrades for them?
Thanks,
Frank

Hi Folks,
After success with a Robitronic pro master dyno to analyze brushless systems, I thought it would be good idea to pool our information.
Here is a brief explanation how I operate my dyno with a brushless setup.
1. Install brushless motor into dyno as you would a brushed one.
2. Connect a brushless ESC to the motor.
3. Connect ESC to Receiver as you would if it were in a car.
4. Connect 4.8-6v supply to one port of receiver(I use 4 cell 150mah battery pack)
5. Connect Power Output from dyno to main battery input of the ESC
6. Turn on transmitter.
7. Apply full throttle on transmitter at the same time as starting dyno test routine.
8. Upload plot to the Internet and post results here.
This method tests ESC as well as the motor. By using the same motor different ESC can be compared.
Here as some comparison that I think many racers would love to see:
Various ROAR spec motors
eg, 10.5, 13.5 & 17.5
Brushless - Brushed
10.5 - 19t
13.5 - 19t & 27t
17.5 - 27t
21.5 - Silvercan
Various ESC.
Novak GTB/XBR, Speedpassion, GM, Tekin etc
Efficiency of low wind motors for use in 5 cell modified racing
eg. 2.5 - 4.5 turns.
If anyone is generous enough to post dyno plots could they please add text of various data incase we lose the picture.
Regards,
Jevon
