I didn’t get to circle back to this subject over the weekend. Please see the attachment. There are 60 motors plotted on this chart. One red line limit is 56.5mm the other red line limit is 60mm. Simply look what falls in-between. The ProBoat data (orange circle) is slightly skewed due to the fact that bearing protrusion was included in the measurement to capture a worst case scenario. I am relatively confident that if those motors were remeasured they would fall at/or under the 56.5mm limit. And for the record, I am not campaigning that 56.5mm needs to be the limit. I simply started there because that’s where we started way back in the day. Our need to go faster, and continue to push the limits of the power system forced us to look bigger, longer, better (motor the fuse mentality).
What does the attachment show? It shows a several things
• The addition of the weight limit last summer was a stop gap solution to keep a particular motor out and curbed another level of pandora’s box being opened for this class (which worked).
• I would also say that weight isn’t necessarily a predictor of performance as the CORE brand/s of motors being used weigh less than their longer and heavier counterparts.
• Look at the sample size; The AquaCraft and Proboat motors is what the majority of racers are using…. still.... I know, I know, discontinued motors, Horizon purchased Tower yada yada yada. But at face value Tower still has 2030’s and 1800’s in stock. HiMax still has the 1500 on their website (same PN listed in the NAMBA rule book).
• It shows what adjusting the lower limit to 58mm allows the TP motors.
Here is my pitch…. Set the limits to whatever you feel is appropriate. Provide the membership enough information so when voting time comes they can make an INFORMED decision.Comment

Haven't looked at the chart in a while. Thanks for posing it again Mike.
60mm sure picks up a lot of motors. Raiders, all the Proboats. I think 60.2 would pick up the Turnigy but I don't have my heart set on that.
Currently there are only a handful that are over 265g. Does a 60mm limit achieve what we were trying to dodge with the 265g limit? I know that weight limit squeezes out a couple TP motors.Noisy personComment

We’ve had a few running the Turnigy and they have all burnt up one or more of them.. again this is my opinion on the size.. it leaves the door open for a bunch of motors..which can been seen 2 ways.. as for the 265 weight limit.. I’ve shown u guts my pics of the 1415 cut down that is 259 grams before I cut the shaft..I’m hoping things go well as the namba list is pretty much obsolete at this point..mike ball I haven’t heard back from you yet.. I responded to ur pm.. anyways guys.. off to skies.. hope everyone has a great dayComment

Ray, you got it down to 265. Was it still over 60mm?Noisy personComment

Here ya go terry.. with wires cut and shaft cut it’s now at 247
This is at 61.5mm. No way could u get this down to 60mmComment

Guys, like it or not the ONLY fair way to normalize motor performance is to list just one or two legal motors. Nothing we do will make everyone happy, it has to be a limited compromise. This is just like the old ROAR motor classes, impossible to make it “fair” for all. Limited classes suck if you desire true “fairness”, it’s always been that way, always will be.

I'm okay with a limitation versus an IROC kind of thing.
Equality isn't really possible unless one guy builds all the bosts, sets them up the same, same battery, same prop with the same exact prep work.
Sure sounds like 36.2 x 60 is pretty good. Not hearing a ton of whining on my end. 36.something.Noisy personComment

Hey Ray,
Personally, I don't have any further topics to discuss at this point. I only wanted to make sure you comments elsewhere with regards to the IMPBA and P-Limited wasn't misleading others. Secondly, there really isn't a need to have a discussion about NAMBA and IMPBA working to commonize on P-Limited because NAMBA is already moving forward with a proposal. Several months ago Brian and I had a few short phone conversations, but this most recent proposal was never brought up. It seems to me the #1 priority of this proposal is the shear quantity of motors it allows. If that is the objective, and your previous comment about the 60mm limit allows 20-30 motors, it seems you've succeeded.
Later,
BallComment

Come on Darin. This is a kid friendly forum. I've never seen them in carbon. When did they start that?
Some things I didn't think of before. Imagine you actually did have to tech one for a protest.
Guy standing there with a a motor in hand and it's over a tic but still has the connectors. "Yer over" He then clips off the connectors with side cutters. Taking with them the solder and a blip of wire in the cup. Now he's under. Oh but he was supposed to de-solder not cut. Is he legal? Then what if he did de-solder but didn't flick the solder off the ends. "Go back and flick the solder" Ugh......Do you write the procedure to wick solder into the book?
You guys may have convinced me on the weight thing here.Noisy personComment

I find it odd that, in EVERY OTHER CLASS in NAMBA, where motors are WIDE OPEN and people can spend as much or as little as they want, nobody is complaining about the balance of competition, or that there are TOO many motors available. And, people are TRUSTED to be able to decide for themselves what motor they want to run. Some go WAY overkill (Terry?? Ken?? Mike??
) and others go with the "enough" power method (did you know I set the RC Boating's FASTEST EVER 2-Laps for ANY OPC Tunnel ANYWHERE using 4S1P and a mere 3640-sized TP motor? In other words... JUST enough power... 
)... BUT, we are all able to decide for ourselves in these classes.
Here, for P-LTD, the members involved in the Proposal, who are working to actually SAVE this class and keep it viable in light of the FACT that motor supply is truly drying up, are trying to put a cap on just how much power you can employ, and have come up with a REAL limitation, and for some reason, the racers suddenly can't be trusted to make their own motor choices within those parameters. Somehow, for some unique reason experienced ONLY in P-LTD, the "balance of competition" is somehow going to be disrupted if there is more than one or two motors to choose from?? Really?? Not the case in ANY OTHER CLASS, where things are WIDE OPEN, but here, with a REAL limitation, the sky will fall??
Just can't wrap my mind around that odd dichotomy.Darin E. Jordan - Renton, WA

Holy crap!! All kidding aside..I couldn’t have explained it better..that being said I have been being bombarded with people who just can’t seem to understand the size thing and or want a bigger size.. which we have tried..even some saying well what if it’s cold and my motor fits but when it’s warm outside it doesn’t..I get people will always push the limits.. that’s a given.. but a simple go no go measurement.. if it fits it’s legal.. if not it’s not... also on the namba side if a club decides to run a different size that is their right.. have at it!! That’s how we can keep growing.. this is for a national rule.. which by the way is just bragging rights as terry says and trophies..I truly hope the 2 organizations can come close to being on the same page. And maybe people will race more or travel to some races more..that being said��.. winter warmups in beautiful Arizona in February!! Sorry had to��Comment
