More limited motor discussion

[Jeff]

Outsiders summary
1. FE spec rule proposal sent to IMPBA
2. 10 pages of suggested changes to rules already submitted. Namba officials weighing on IMPBA
rules.
3. Approximately 12 people involved in discussions representing many others.
4. IMPBA board of directors see you do not have rules right. People can’t even agree if they want classes eligible for records.
5. Board decides you should get rules right and run them for this season. Decides not to except rules submitted as changes are already being discussed.
6. People get mad, stomp their feet and start holding their breath. Disparaging remarks are made about the board.
7. Thread further derails to esc questions and set up information. Strut depth is discussed. What’s next, chocolate chip cookie recipes?
Insulting the IMPBA board of directors will not further your case for rules, just saying because it obviously needs to be said.

Well,

We had our club meeting on Saturday and there were a few people that brought motors. I didn’t get the variety that I had hoped, but I don’t think it would change the trend/s we are seeing. We have 44 line items some have several samples from the same manufacturer and others we only had one sample. I am confident that we captured several samples of the currently being used. I have attached a PDF that lists the motors and their measurements. Most importantly I wanted something charted making the relationship more visual.

Couple of quick notes;

The NEU motors listed under 14XX (Blue Diamond) – include all of the motors we would “expect” to fit in the 36X62 size limit i.e. (1409, 1410, 1412)

There is a “normal” 1415 listed in line item #40, but I narrowed the X/Y chart limits to exclude it.

The “modified” 1415’s have their own symbol (Green Square). I felt that giving these motors their own cluster was needed.

There is a slight difference in the Dynamite cluster, because of the measurement method. I am going to assume those that provided the length measurement to me didn’t include the bearing shoulder on the output side. I included that when I was personally measuring.

Go Nuts!

Mike, I would keep the measurement STANDARD. Extra words/language for "bearing shoulders", etc., are just going to add "gray area"...

Hey Mike , great work....thanks for your diligence.
Darin certainly knows the intricacy of these measurements thx for your work too.
I did notice the Super EDF 3659 motor from Turnigy appears to be missing, or it could be
called something else. We have had some race successes with that one so it probably
needs to go through the process too. I can send you one that I smoked last year at the Cup if you want.
I did just measure it with a caliper. It is either 60mm or 60.6 depending if you measure the can, or
actually on the raised mounting edges (easier to understand what I am referring to if it was in front of you)
It is 35.8mm diameter. I do not have a small scale here but I may take it to the Post Office today.
My bathroom scale says it is 0.0.....rather odd because it always reads heavier that I believe when I get on it.....hmmm

Hope this helps and lets keep the positive stuff going
I think these efforts will pay off.

I think this is the motor that Ken is talking about;

I still have one collecting dust.

It's such an interesting design. The stator coils are like a 2 pole, weird.

Yes Larry, That is the same motor I am talking about.
Just purchased a new scale from the office store.
That motor weighs 255 grams.

Mike,
I can simply give you one of those motors in Atlanta
for your growing collection....:)

[Doug Smock]

Nice work Yer FE Lordship. Thank you sir!

[rayzerdesigns]

So why not go back and just change the dimension to 36.3 x 58 or 59

Thanks Ken,

I will add to the list. There is no need to give me the motor. I am simply interested in the actual length, diameter, and weight.

Later,
Ball

Hey guys. Just caught wind of this, good for you trying to make a National set of rules for P Spec., it seems to be one of the most popular motor classes.

As an outsider and CD for an IMPBA race and two record trials a year can I ask you to please, please, please keep it simple enough so a guy like me that routinely lets the magic smoke out of anything electric can easily tech it in the field. When it's dark, pouring rain and 40* out!

Thanks in advance!

[Terry Keeley]

Not sure what's going on behind the scenes on this but I can tell you from experience that National rules tend to evolve from local rules that work.

The change to the "three boat length" passing rule I submitted a few years back is a perfect example. Guys were using the "shall not impede" at the local level for several years and it worked well. When it hit the Board there was little discussion as they knew it was already working in the field...

[dethow]

Why are the moderators removing posts which break no rules? Can you say censorship?
I'd appreciate an explanation from whom ever has deleted multiple posts of mine.
Next time... I'll just run my motors and say nothing. I put my money and neck out on the line here for the better good of this hobby and the potential classes. What do I get in return... censored????????? And yet HE persisted.

Your' welcome guys.

Purely proved my point... THE GOOD OLE BOYS CLUB!

[Doug Smock]

Perhaps because you don't stay told David..

The IMPBA BOD is drawing on 69 years of experience. This will work out fine...

At this point I think Id like to see this thread die in peace.

We are all adults and can/do respect each other. So I'm asking unless there is something very new to add to this thread, please let it go for now.
