NAMBA P-LIMITED Motor List - Pro Boat Motors NO LONGER AVAILABLE

[Darin Jordan]

And, I too agree that it's silly that this rule-set is NOT in the rulebooks for IMPBA. HOWEVER, I think it was wise to NOT put the CURRENT NAMBA Ruleset into IMPBA rules. Too Vague, as we've found out, and not sustainable, as the subject of my post proves.

Defining the class based on a motor dimension, however. Rock Solid, sustainable, TECH'ABLE, and COMPETITIVE. Rule is BLACK and WHITE. No inarguable reason why it shouldn't be official, especially since it's sustaining FE Racing in both organizations.

But, I'm just a member. I'll let the powers-that-be sort all that out.

There's no down side to a weight restriction either. Keeps honest people honest. The likely hood that someone will protest a motor and force weighing it is so slim it's virtually non existent.

We've had the "as manufactured" in the book since inception despite the fact that very very few people even COULD have verified it. "Well....... it's in a gold can must be legal" Guess how many protests to verify "as manufactured" there have been since limited was penned?..............ZERO! No motor protests. Ever. So all the tech fear is unwarranted. The weight would simply be a point for builders to stay under. You know if you're out there on the edge. The type of racer that would max out that part of the spec is versed well enough to build accordingly for easy tech.

It's like the 65% trans rule. You rarely have to check that. When you're building a sporty though.......you use that as a guide.

Just me speaking, and I don't have anything to do with the current proposal that's in the works, outside of all my initial testing and research, but the weight thing makes people "feel good", but really adds a lot of "gray area" to the rules.

I'm for keeping it simple, and not requiring that a boat be torn-down to verify legality.

[Darin Jordan]

Then again... I've been wrong before...

[T.S.Davis]

Wouldn't the time required to build those monstrosities be better spent turning laps? Or maybe getting a boat to run free and clear?

Certainly... or understanding how to prep and tweak your own props...

There are negative side-effects to all the above... like, how do you effectively water-cool them??

As Darin has already pointed out; they will need to be cooled... Those showed up on IW a while back. The more I've had time to digest it the less those scare me. The core group of motors being used are far shorter and lighter than any of the current limits.

The weight thing was a temporary solution to a permanent problem.

In retrospect, the thing I find funny now is we immediately made the jump to 5.5mm connectors on the motor side.... why? more, more, more It sure would make things interesting if we included a specification for a max diameter on the motor connectors and a requirement to leave one solder joint exposed. LOL we are using connectors that accept 8-10 gauge wire, but the stock controllers (we started with) used 12-14 gauge wire? Just an observation.

LOL I'm out!!

I don't blame you sir.

Anybody live near Doby!?!?!?

Me. I'll take care of him. He flies planes mostly now so it will give me target practice with my pellet gun. :)

Thanks Ray!

The proposal should be to allow the "NAMBA BOD" to make changes to the "Approved List" based on the criteria already in the rules. The Electric chairman can recommend what motors should be added to the list. That way they can be updated on an annual or bi- annual basis. Real Simple.
No other guidelines need to be added.

JMHO

I think to maintain "The motor is the fuse" mentality the connectors had to be changed to keep the failure inside the can where it belongs. Just playin fellas, I couldn't help it, sorry...

For the record.. yes the proposal is written.. will be voted at d19 year end meeting with the assumption if it passes that it be sent to national ASAP.. I see both sides of the weight thing.. but the size limit is a clear black and white. No need to even pull motor out and weigh it.. it either fits or not..the weight leaves a lot of grey area..will it be the solve all?? Maybe not.. but in NAMBA land.. we have one motor available now..in all fairness to that.. one motor is honestly the only way to make p limited 100% fair.. but we’ve had that discussion..I hope the new proposal passed and the bid at NAMBA will pass it.. and maybe even impba will accept it.. would be great to have both organizations have the same rules for some fe classes.. might make traveling to more races for all seem more doable.. and for those of you asking about me Newlands whereabouts.. trust me he is here watching.. lol.. and I credit him for the wording of the new proposal

Slew of things wrong with that.

You have to keep revisiting it.
You have to cater to brands.
You may well need to test new motors.
We already KNOW they can be rewound. Can ya tell a factory from a rewind? On site, at a race, with normal humans tools?
Can you tell if the bearings were changed? Check the bearing serial numbers I guess.

Adding to the list just perpetuates what was wrong with the rules all along. It's whats wrong with scale in both orgs. Untechable nonsense.

Length x width x weight doesnt need to be interpreted, updated, reviewed, revisted........ever.

The limited rules held up for a long time but not because we got it right. It held up because we had or heads in the sand.

BTW, the 2000 motor that comes in the Veles and the UL19 is not NAMBA legal but is still available. Although they look the same, the motors from the list are not manufactured by the same company that makes the 2k for Proboat. The company that made the old 1500/1800's is not making motors any longer. My understanding.

I thought this was judged to be NAMBA legal, earlier this year. A couple of us switched to it for local club racing. Runs great and comes back cool. So, we couldn't use it for a NAMBA event at another club, eh?
