Blueprinting UL-1 Motor Wires

[properchopper]

If it isnt legal to reinsulate your wires...... that make this sport kind of a rediculous joke. Really.

Really ? The spec (or P-Limited) classes specify certain motors. If, say, I was going for a 2-lap record at a NAMBA sanctioned race I'd know through testing what the most agressive prop I could run before melting the motor leads on a stock/spec motor. Then someone shows up with modded wires to allow a more agressive, faster prop. He goes faster and gets the record. The idea behind P-Ltd classes is to have motor parity, as best as possible.

In the now defunct LSO class, section 28/g/jjj/vi of the NAMBA rules state : " No modifications may be made to the motor. Except for normal wear, it must be run as shipped from the manufacturer."

In the Electric 1/10 Scale Unlimited Hydroplane class in NAMBA (which allows Himax HB3630-1500,Blackjack A3630-1500, or AQ 36/56), 28/C/iv/b states : "No modifications may be made to the motor. Except for normal wear, drive flats or keys,electrical connectors, and water cooling, it must be run as shipped from the manufacturer."

I don't have the rules for P-Limited motor specs but I suspect it will follow the 1/10 class specs.

I await further more learned input.

Well if you used the same color heat shrink how will anyone know

STEPHEN !! The point is not to break the rules.

So LSO doesn't allow water cooling or the addition of connectors? most motors come without connectors and are not water cooled.

[CHIEFY_44]

I understand that tony and im all for rules and will & do abide any rules, all I was pointing out was like every rule/law there is away to scheme or bend rules. The answer to one is aquacraft need to use better grade heat shrink, or make a ruling for a spec prop and have a specific timing everyone has to run, thats mpo anyways.
For the record I dont believe in cheating at anything and if namba or anyone turns round and says this is not allowed I will return my motor to aquacraft for it to be repaired, no biggie, but I thought the reason for spec class was to make it cheaper/easier for the beginer to race competively so adding some extra heat shrink to help stop motors burning up imo is no biggie, whats up people dont we want more people to join our great hobby or not, but like tony said in a earlir reply darin or someone needs to step in and sort this out ASAP.

It allows for water cooling. These motors come in RTR boats that have cooling jackets on them stock.

[Boaterguy]

I see, it requires motors from RTR boats.

ive put new covering on my motor wires but never that far in. I will be now. Thanks for the pics showing how you do it

+1. Good advice, thanks!!

It depends on the CD, If it is me I would say that the pictures tell the story! Maintenance to prevent future problems and in my mind acceptable.

Randy, my fear is that reinforcing the insulation could allow the motor to better survive being pushed harder and be interpreted as creating an unfair competative advantage. No problem with sport running, but in spec racing all motors should have equal survival potential. I have a bad feeling that I goofed up here by illustrating a "mod" that very likely can be construed as outside the rules.

There was a very protracted and learned discussion regarding insuring parity in spec motors and the "teching" issue before spec was introduced as a NAMBA class. The overall consensus, as I recall, was that above all we must all be honest in conforming to the rules. I think that reinforcing the insulation opens the door to the teching thing, and I don't want to go against what's already been agreed on and start another reason for re-opening that discussion. I hope my flogging will be over quickly.

Or you are fixing a deign fault. Neu motors have chaged the way wires exit their motors because of past faults from wire vibration.

There is a point to which these motors fail that your mod will not help anyway.

Ray, you're on the money there from what I've experienced in toasting lots of spec motors. The stator windings will likely fail long before the lead wires, and the rotor will let loose before the leads as well.

I have added additional heat shrink tubing to my motor leads for 3 years now. I do this right after I solder new 5.5 bullet connectors on, and just cut the heat shrink long enough to cover the bullet and to extend into the end bell. It is quite easy to nick the OEM insulation and tear a hole in it. This is more of a general maintenance item IMHO. Worn spots can also develop quite easily on the insulation in out board applications too. I wouldn't worry too much about this violating the current rule set for P-Ltd in NAMBA.

Gotta love FE rules...ambiguity at its finest.

I have done this as well in my sport boats, but have not needed to in boats I raced as last year was my first year and our local IMPBA sanctioned club didn't have any races this year.
