P-Limited Motors - Im going to jump on the hot seat.

[ray schrauwen]

Thank you for your hard work Darin! Several times I almost bought one of the NEU's but, balked. I'll test the SK3-1900kv motor I have.

----

The SK3 can't be taken apart unless people know more than me. I can still measure the rotor length and field length.

[ray schrauwen]

Turnigy SK3-1900kv

Rotor length 39.6mm

Winding length 46mm

4 poles

D wind

35.8mm Can OD

60mm exterior Length

This motor is packed with copper compared to an AQ 2030, 1800 or PB motors I've had.

keep us updated darin...

Most times the end bell is glued on. Hold the motor in your hand and tap firmly on the shaft it will come off. Then put the motor back together and carefully drill and tap threw the can to the end bell.

Most likely Randy. I don't want to take it apart unless I really need to. If I tap out the end bell it may damage the bearings.

Ray,

Greg Schweers is going to send me one of these motors to add to the test pile.

I agree with testing..they need to be equal..or very close to it..be thankful we font have the legality testing that we do on the car side..here is a pic from motor tech at roar nationals this past week in california

If it ever gets that anal in the FE world, I'm outta racing...

It's probably the most even and fair racing in RC. Lot's more people involved and many fewer classes.

[Doby]

Probably true...but really, to what extent do you take things before it becomes "not fun" and more of a PITA for the race organizers and competitors. Toy boats...toy boats.....

[raptor347]

Not arguing. It's the big sanctioned races need that level of scrutiny. Some of the problem comes from the technology available in FE. It's easier to stray outside the lines with what is available today. You have to be pretty creative to cheat in most of the IC classes, it usually requires a conscious choice to combine parts that will put you outside the rules.

With regards to FE inspection:
For club races, no real need unless there's a problem with cheating in a particular club.
Nationals, probably should but usually don't.
Time trials, definitely.

Honestly, it's with regards to record trials and records where we hear "was it a legal setup?"or it was "special team motors". Even then, it's online afterwords by non-participants, not at the event.

its still fun racing..its a pre qualifying racing inspection..then motors are sealed...it makes for very even and close racing..top 10 qualifiers in stock were all within 3 seconds over a 5 minute round..cant get much closer than that

IIRC all of the noise stemmed from the lack of answers when asked about the procedure for technical inspection of the limited motors. I imagine the noise makers that are still interested (if any) will continue to have questions unless there is a clear procedure technical inspections adopted.

Darin is collecting some internal data now. I imagine putting some of that in the rule book would be a good start. Or, we can keep doing what is being done and expect more of the same.

Just my .02 FWIW

OR we just eliminate P-LTD from record eligibility.

Do you have any idea how much hand wringing this would make go away? I would support this 100%.
