Blueprinting UL-1 Motor Wires

[ray schrauwen]

Actually our club has had very good success with a "spec" N2 Sport Hydro class. All motors are the same, and the club bought identical S&B props which everyone has to use as-in, no tweaking. If that ever becomes an issue in the future we'll just collect all the props after each heat and randomly redistribute them - problem swolved. We have three different hulls running very close together in speed, that means very close racing. Would this work in the P-Limited classes? Probably too complex, especially since the current formula is so successful. We developed this "club class" to allow our older LSH hulls to still race since P-Limited power was too much for the smaller hulls. Speeds are still upper 40s....

That's how it is today, although the original LSH class was designed to be a beginner's class. From the 2006 NAMBA rule book: "Experienced racers are strongly urged to consider the skill level of the opponents when running in this class, since the intent is to encourage less skilled racers to have success." .

What motor and prop do you guys run in N2 spec' Hydro??

I'm in the northwest and I've burned up six UL1 motors this year. I do think the quality of the motors has changed. At the beginning of the year I decided to change the motors in my LSH and my spec rigger -- both boats ran the same motor all year long (13 races). The first race of this year, the third heat, the motor burns up in LSH. The second heat the motor burns up in the rigger. Race two: new motors in both boats, running the same props as last year, both motors fried. Third race: Bill and I decided to try the new Castle Mamba 2 car controllers. We thought this controller would work good because it's waterproof and has a built-in fan. I set the timing to 8. First heat, the motor burns up. Bill's boat comes in and the temperature is 165. He runs it the second heat and his motor burns up. So, for the hell of it, I put a 240 ICE in the LSH, now I'm running the timing to 6 (I'm a little gun-shy now). First heat the motor comes in at 145, pulled the controller out and stuck the Castle 120 back in the boat and I also depitched the prop back to 3.0. We had out Gold Cup Race a week and a half ago; we have two lap time trials. I decided to stick a 447 to try for two laps; the boat goes 1-1/4 lap, the motor burns up. What bugs me is that I ran all last year with the same motor and prop without any problems. I've sent back 11 motors so far this year; they did replace three under warranty and a discount on the others. With the motors I've run this year it's like a new learning curve. The problem is I run six boats and five of them have UL1 motors and the 1/10 scale has a Pro-Boat.

Greg - are you serious or are you pulling our leg?

Doug, He's serious... I've seen some of it. It's very odd...

If you guys recall, the same thing happened to Pro Boat a few years ago... BJ26 motors were burning up left and right... Manufacturer changed the process for assembling the stators... essentially SKIPPING epoxying in the wires to the iron... They had shortened the magnets in the rotor as well. Luckily, I disected one and caught it pretty quickly and they (Pro Boat) were able to get them made correctly again.

All that said, it's still a decent and fun form of racing, locally especially. It makes a good place for those with off-the-shelf equipment to have a fun, competitive day, and in most venues, I think they can be reasonably successful, or at least enough to try to learn to race. At a National level, the purpose builts have the obvious advantage, but a well setup and driven RTR can still be competitive.

If this economy would ever get back on track... I think that more would venture from the RTR/P-Ltd formula into more open classes, but until that happens, I think this may have helped keep the hobby alive a bit.

Just my view from the lense I have available. :)

Looking forward, Doug, to seeing that new Trailer of yours parked next to Haines next year! Should provide the rest of us with some nice WiFi, Hi-Def, surround-sound entertainment! :)

When Greg said he stuck a 447 on the boat i thought for sure he was kidding. As aggressive as I am I can't imagine a 447 on a 2030. Must be really - really worked.

Darin - Looking forward to meeting you finally at Michigan. My trailer will be mostly set up for hauling as 3-4 of us travel together. However once we get the RC stuff out we will have fold out couch's, beer cooler, disco lights and a stripper pole. :) I expect our pit to be a popular area. :)

I think that his props are generally worked and reduced in diameter. Not too sure beyond that.

...and a stripper pole. :) I expect our pit to be a popular area. :)

I think you just one-up'd Ken there on that one... :)

Hey Doug, Be careful on the pole, it's bad for your back.

Hey Doug, At your age I'd be careful on the pole, it's bad for your back.

[DPeterson]

LOL Tony. I have been working out so I will be in good shape for the pole dance. Can't wait to show off my tight under cheeks and such.

I am traveling all week living in hotel rooms and working weird hours. We'll hook up by phone next week.

I wish that there was a born on date or lot # stamped on each motor so we could tell what batch a particular motor belongs to... Similar to ammunition lot #s.
