Blueprinting UL-1 Motor Wires

[Doby]

I wonder if the color of the heatshrink helps?

I've heard blue is faster than red.

SHsssss... I thought we were going to keep that a secret !!

Well - I just cut the small black over-shrink off the motor wires from an old and very used UL1 motor. I could clearly see where the tight over-shrink was squeezing the 3 wires together during heat occurances, was eventually going to lead to shorting out the motor. I will now be removing the black over-shrink from the 3 wires on all my UL1 motors and putting a dab of silicon in this location to keep the 3 wires seperated and from rubbing on the can opening.

I was warned about this issue during my last race at Michigan but it didn't really sink in until this thread. Thanks to Tony and all the contributors for bringing this issue up. Our motors will now run longer with these simple preventative measures.

THRUST BEARINGS! Anybody got one?

Incidentally, when I needed to run a UL motor on a Hydra120 I contacted Grim to find out what the timing is on the stocker. I run one degree less because I'm not confident that the two manufacturers are identical. The AQ is metric. HAHAHA. Works okay.

Just kind of curious. Just what is your interest in this subject? You both are IMPBA members and not NAMBA members. IMPBA currently has no P-Limited rules on the books. You have no dog in this fight. The 2011 NAMBA Nats was in your back yard and neither of you attended. Please tell me you are not "popcorn posters"!

What we are discussing here are preventative measures to take to lengthen the life of the spec motors allowed in the NAMBA P-Limited classes. This seems to be consistent with the goal of the class - entry and affordable.

I am a member of both organizations and travel extensively to both venues to race. Therefore I consider myself to have a large dog in this fight.

My only intent was to warn Tony that someone may question the legality of his mod in a trials event. That's all. Despite all the ridiculous comments about bullet connectors, heat shrink and cooling jackets, you won't find any opinion by me on in this thread because I am not a NAMBA member so it's not my place.

Tony stated he doesn't do the mods on his trials boats so the point is mute anyway.

I did find some useful comments on this thread that will be helpful when the IMPBA composes its own set of Spec ("limited" if Smock has his way) rules in the future.

Have a safe holiday weekend folks.

This whole Spec P-Limited thing baffles me. The P-Limted classes are an evolution of LSH and LSO. The only thing speced was the motor. Nobody gave a hoot about the esc, the connectors, the wires or the shrink wrap. Now it seems there are a hand full of guy's that think a lawyer should get involved and write up a 100 page document.

Fellas - go racing with your friends. It will be OK.

I am a Namba as well as Impba member and therefore have a vested interest as well. But I don't see how calling out Smock has anything to do with the issue. All he did was merely point out the once you went to a 240 esc, you popped two wires on your motor. This was nothing more than noting that theoretically, the AQ motor can ask for more than it is capable of and a larger speedy will oblige until something gives. He supported the idea of shrinking the wires in his first post on the subject.

Actually, he entire question regarding shrink on the motor is moot because the connectors are allowed to be changed. At that point, shrink can obviously be applied regardless of the application being for heat racing or trials. Simply shrink the wires all the way down. There is no restriction in the rules regarding shrink at all, but surely you can shrink the new connectors.

Common sense is all that is required to come to that conclusion.

Mirriam-Webster defines FORUM as : " A meeting or medium where ideas and views on a particular issue can be exchanged"
Tony

Dang Doug you're still chewing on this?

Drive on sir, like you said, it's going to be ok!!
I do want to thank everyone for the friendly discussion, lots of good information here.
Have a great weekend!

Bill I don't recall mentioning the ESC thing at all in this thread, nor did I mention Mr.Peterson smoking his equipment. But since you brought it up, you would think that with his extensive travelling to races etc., those kind of mistakes would be a thing of the past. Obviously the timing thing is much easier for rookies.
Looking back I think all of my posts,(and Chilli's) were of a positive nature.
I think Doug must not lke the way we comb our hair.
Have a good one fellas!!!

bbill1, Hard to tell how much experience a guy has on this forum. I did not smoke 2 motors due to switching from a yge to a hydra. It was the advanced timing that smoked the motors. The esc feeds the motor what the motor asks for. Again - the UL1 motor does not like advanced timing. It was definetly a rookie mistake on my part and very stupid of me.

Doug, I didn't know you had hair. :) My anguish is not of a personal nature. It is with rules. Over the last 10 years I have rebuilt my race fleet 3-4 times chasing technology and the rules that followed. A couple of rules that I consider to have been major mistakes (2P and length limits) has takin us into the area of running mainly P-Limited classes. OK - Fine, lets play with weak, cheap and badly engineered Chinese equipment. OK - Fine, we have rules that are working. So anytime, rules or issues are being discussed that may effect my racing and or my race equipment I am going to get a little cranky. I will not be re-building a race fleet again.

Got 3 big race venues this month. See you there.

Never said you smoked two motors, I repeated that you stated you burnt two wires on a motor. The point is (which is kinda off topic) that if the AQ speedy was used instead of the Hydra 240, the timing issue would never have come up. Thus you would not have burnt the motor.

I consider the P-Spec tunnel class a jump off for nitro tunnel heads like myself. Considering that, the Namba rules of allowing any esc in P-Spec tunnel can potentially cause a person new to FE to burn up equipment due to the lack of knowledge. I'm kinda playing both sides of the fence here because although I use an AQ speedy, I do believe that people run a 120 speedy in the p-spec classes simply because they believe it gives them an edge. Personally, if you want to run a different esc go right ahead. Cause all I wanna do is race. Since I am a Namba and Impba member, It made more sense for me to use the AQ esc so I could run anywhere and be legal.

As far as experience, I have only been into the FE thing for about 8-10 months. Racing nitro boats, 6 years. But six years here in Fl. is like 10-15 anywhere else. You will not find a more densely packed group of world-class racers anywhere else on the planet than here in Fl. On any given one day race here, you could be stacked up against multiple us1, and world record holders.

And That could be the easy heat.

[DPeterson]

OK - good to know where your coming from Bill. Wish I had got to Florida for the 2011 Nats. Schedule did not work for me.

Here is my take on why new guy's will burn their equipment in order of cause. 1. Running their boat way too long. 2. Over-proping 3. Running the boat wet 4. Cooling system not working. 5. ESC timing. These are the causes I have seen the last few years for equipment burning. Sure - specing the esc may save number 5 a couple of times. How do we save number 1 through 4?

Later - Doug

Oh yeah I still have hair.LOL
I understand Doug, no doubt about that.
One more oval race and two Time Trials left for me this year.
Good luck at the races!!

PS The answer for us on 1-4 had been education. Still zero failures to date.

[DPeterson]

Doug - We really do need to get together and race sometime. These thread discussions just don't cut it. :)

Fair to say then that education also takes care of number 5.
