HFAY 70-turn Season 6 Spec Motor Tests

PN Racing HFAY 70-turn Season 6 Spec Motor Tests

EDIT... - GUYS, MY MOTOR MASTER MAY NOT BE WORKING PROPERLY SO THE AMP DRAW READINGS I GOT BELOW ARE PROBABLY NOT ACCURATE SO I REMOVED THEM. THIS IS BASED ON A COUPLE OF OTHERS TESTING THE MOTORS WITH DIFFERENT EQUIPMENT. READ ON FOR OTHER TESTS.

I HAVE A NEW MOTOR MASTER COMING AND WILL RETEST WHEN I GET IT.

THANKS,

GREG

I recently purchased 5 of the Season 6 Spec motors and did some initial bench testing on them. All motors were broken in on a Much More Platinum Motor Master in Break-in mode.

Step one was done with the HFAY motor on slave mode driven by the master motor on the PN Racing Motor Test Stand. The Motor Master was set as follows:
  • Low Voltage 1.2
  • High Voltage 3.5
  • Profile 1
  • Duration 8 minutes
  • Cooling period 2 minutes
  • 2 cycles

Step two was an 8 minute Break-in powering the HFAY motor directly from the Motor Master using the following settings:
  • Low Voltage 1.2
  • High Voltage 3.5
  • Profile 2
  • Duration 8 minutes
  • 1 cycle

The bushings were oiled at the beginning and end of the break-in runs. Additionally a drop of VooDoo fluid was used before the powered break-in.

#1 HFAY 70-turn Spec Motor
4.8v RPM 23,730

#2 HFAY 70-turn Spec Motor
4.8v RPM 24,300

#3 HFAY 70-turn Spec Motor
4.8v RPM 24,180

#4 HFAY 70-turn Spec Motor
4.8v RPM 23,730

#5 HFAY 70-turn Spec Motor
4.8v RPM 24,750

For Comparison my Season 5 Spec motor delivered the following after I removed it from my back up car. For what it is worth I never used this motor in actual HFAY races. It was certainly faster than the stock motor I ran but I was not as consistent and ran a lap or two less over 8-minute tests.

Season 5 HFAY Spec Motor
4.8v RPM 36,960
.95 Peak Amp draw
.92 Average 4 step (1.2v, 2.4v, 3.6v, 4.8v) Amps

And a couple of Kyosho Stock motors I used over Season 5.

4.8v RPM 33,800
2.55 Peak Amp draw
.85 Average 4 step (1.2v, 2.4v, 3.6v, 4.8v) Amps

4.8v RPM 32,350
2.93 Peak Amp draw
1.17 Average 4 step (1.2v, 2.4v, 3.6v, 4.8v) Amps

Question: 4 of the 5 motors have an average amp draw of 2 Amps or better. This is quite a bit more than spec at .481 amps and about double a stock Kyosho. Does anyone know the original spec test conditions?

Question 2: If you had the choice to pick one of the 5 which would you choose and why?

Now, on to the track tests!

Thanks,

Greg
