    They were legal at the club level.. and the 2000 was added for the nationals in Dallas.. the proposal being submitted both of these motors will be legal..

      Terry u still need to sell me on the weight thing.. I just don’t see why it’s necessary..I see both sides.. but nothing has been proven to me why it should be added..if the size is right why have to pull and weigh?? To many variances on what are the rules for the weight... wire length.. plugs on or off... I’m not 100% against it.. just trying to figure out the thinking behind it

        36X60 would surely open up the current list and should eliminate the need for a weight limitation. My question is will there be any grace on dimensions? 36.00-60.00 exactly or a small percentage say 1/4-1/2% for manufacturing tolerances or calibration discrepancy?
        1/2% - 60 X 1.005 is 60.30. 36 X 1.005 is 36.18 (1/4% would be 36.09 X 60.15mm) Hope this doesn't create to much discussion.

          Consider this Ray..... New motor comes along with a rotor made with some unobtainum core. Same size but more power because it's simply more dense. Retooling the fleet.......ugh....again? Keeping someone from coming up with something nutty is the only reason for the weight limit. Is it possible? Sure. Is it likely? Doubt it.

          We've been through the HOW to do the weight thing already. Bare motor with no connectors under 265. Build accordingly. A motor is not it's connectors, or the jacket, or the coupler.

          All THAT said..........lose the weight aspect and it does become crazy easy to tech forever and ever amen. I have a gauge I keep in my toolbox to check.

          The truth of the matter on the motors........we've had the loosey goosey rules for nearly a decade. Despite the rule being very nearly un-techable we didn't see or hear of guys trying to skirt the rules too bad. There was modifying the shrink wrap on the gold motors and that a was about it. Did that myself till asked not to by Dave. I also water cooled the wires. That worked sorta.

          So is someone going to spend a lot of time finding a rotor of high density frankincense and myrrh? Proly not.

          Tolerances is how we ended up at 62. That's when guys went crazy with machined motors from the next size larger family of motors. We all need to just find a dim that makes sense and live with it. If it's 60.1 x 36.2 then so be it.

            No leeway.. it will be 37x60 for namba proposal.. either it fits or it’s not legal..I get what ur saying terry btw..

              Curious, what motors fit in the 60mm limit that doesn’t fit in a 56.5mm limit AND is currently being raced on a regular basis?

                Well, since no one else wants to answer Mike. Or maybe I'm the only one without a life on a Friday night

                TP 3630 - Being raced in many boats. And a great option at $85.
                OSE Raider 3660 - Not sure on how many being raced, but I'm sure some. And a great option at $75.
                SSS 3660 - Comes stock in the TFL Pursuit, so probably is and/or will be in many. And a great option at $55.
                Leopard 3660 - Not sure on how many being raced, but I'm sure some. And a great option at $53.

                And at 60mm there is some room to play for future motors in RTR boats. That way you all don't have people spending $400+ on a boat and then having to change out a motor in order to race.

                  From the data that was collected, the TP motors ranged from 59mm in length down to 57.6mm in length. Another note: these motors are significantly heavier when compared to the standard ProBoat and AquaCraft motors.

                  Yes, this motor is a bit on the longer side of the motors currently being used. I've never personally used one, but I do recall others suggesting this motor wasn't quite as good as the others.

                  Got it, didn't realize this came in a RTR Pursuit. However, if the limit is set at 60mm MAX if they are slightly over they will be illegal.

                  I think it was found out very early in the process the Leopard's don't cut the mustard. I couldn't and wouldn't recommend one to a new boater with a good conscious.

                  So they are going from 62mm to 60mm. Does that REALLY get the class into a safe place? Just trying to understand how 60mm was established and what criteria was used to determine it to be THE dim.

                    I REALLY want try and stay out of this, but I can't resist answering your questions.

                    1.) Does 60mm REALLY get the class into a safe place? Unknown.
                    That will be a matter of opinion which voters will decide.

                    2.) How was 60mm established and what criteria was used to determine it?
                    I'd assume the years of discussions that have been taking place. I think it was deemed 62mm was too much based on easy modification of larger motors to fit but yet this still allows the widest range possibles for current and future motors with the least amount of possible Frankenstein motors affecting parity. The weight limit is the other safe guard against Frankenstein motors.

                    Mike, at the end of the day there is no silver bullet in this discussion. There are probably many good points to what you will obviously be lobbing for which is a 56.5mm limit. Why don't you plead your case on why you think it should be limited to 56.5mm instead of 60mm and then let the NAMBA voters make there choice.

                    Your never ending desire to find the silver bullet answer doesn't seem to exist since no one including yourself has figured that out over this many year process of discussions. These questions have been asked and asked. Time to let it all go and let progress pursue.

                    I think what you (as IMPBA FE director) need to consider is that motors in the 60mm area are not out performing the ones under 56.5mm. So why not include them so that there is less chance of having to revisit this down the road and less chance that RTR purchasers will have to change out motors in order to race?

                    But that's just my 2 cents as I've been closely involved in most of the motor discussions over the past few years. I do think it'd be great to hear from Ray and maybe even Newland with answers to their process and if they maybe agree with you and don't really see a big enough reason to push to 60mm and maybe 56.5mm is enough.

                    I do see where this is going thou... and I see your point. There are 2 choices here (probably in your point of view):
                    1.) Go with 37mm x 60mm with a 265grams weight limit to protect against a Frankenstein motor that would affect parity.
                    2.) Go with 36.5mm x 56.5mm with NO weight limit which will basically eliminate any chance of a Frankenstein motor that would affect parity.

                    I'm again REALLY going to try and back out of this discussion. Sorry for getting involved at all. Did my best to stay non confrontational and I look forward to all this stuff getting voted on so the questions and discussions can end.

                    Have fun with that....

                      Mr Ball
                      Testing has been done and I don’t remember where the big list of motors that fit the criteria is in these forums.. the reasoning for the 60 mm is to keep the higher power neu 1415s out of the equation.. and also to not limit to too few motors..talking with a lot of people here on NMba side this is a consensus of what we have come up with.. and on December 9th we will vote on it here in district 19..with the assumption that it passes it will be forwarded to the BOD to approve at the national level..Is it going to be perfect?? Who knows yet.. but we all know the 62mm was too long.. as for the weight idea being talked about.. most we have talked to agree that for ease of tech to just go with simple size..something has to be done on the Namba side as we are basically down to one motor now..I’m Not saying this is the perfect answer but we are moving forward..it would be great to have both organizations have the same rule set for limited.. heck even all fe classes.. maybe that would help more people travel to different races..sorry for rambling.. hope this explains a little..

                          A while back I did a test with a 29" Mean Machine cat. Hitec radio with GPS and Castle ESC for data logging. Older AQ (good ones) 1800 & 2030, SSS3660-2070, TP 3660-2200,Leopard 3660-X2 2340. leopard 3660-2050. Same Batteries and prop. Maybe 2 MPH difference and watts also similar. The Leo X2-2340 fastest but that's higher KV with the same prop. Just an FYI yes I have seen some Leopard failures with 40mm motors. My LEO 3660's at $53 are in my spec mono and cat plus my grandson's spec boats. No problems yet and going to the races. The 2340 LEO runs very well in a Kep's rigger spinning a cut 1450.
                          Looking back at Darrin Jordans testing with 36mm motors it appears they are all similar. Some better but marginal. Trimming the hull and right prop will be the challenge as it should be.

                              Nothing personal Ray. That's all I can muster now without offending anyone.�� It's all been said. Hopefully they won't count the votes in Fla., Az., or Ga. LOL

                                You went to 60 to eliminate the 1415 and eliminated the Turnigy in the process. Some guys were digging that one. Cheap fun.

                                You could have dumped the 1415 with a 260 gram limit. Or there abouts.

                                What club has been running the 60mm limit? I'm not saying its wrong by the way. You mentioned "been tested". The only club besides MMEU I'm sure has an official rule set for ignoring the list is Puget Sound. I never read their club version. Did they go 60?
