I need to know what to do to make my Death Stars run with the rest of the pack. I've tried gearing , Brushes, straitening the brush holders etc and my cars are twice as slow as most of the others. I could see if it was one but I have 5 of these set ups and they all run the same.
Hmmmmmmmmmmmmm , could be some cheating going on ?
This is the same delima I am up against running 4.5'' Nastrucks. Sucks being passed down the straight like i'm standing still. I know these motors are not suposed to be opened but
their is way to much variation. The shaft of the arms should be straightned and the comm.
trued up and the timing adjusted all the same, for this to be a fair type motor to use in what should be close compitition.
In the 90's we used to have the same inconsistencies with the Parma 16D. The Parma S16D was better, however many of us ended up going to the "super wasp" (it was a green wired arm, not even sure who the manufacturer was). The price was about the same, the motors were slightly higher revving, less torque, but very consistent. Are they still around? Not sure.
Its all coming back to me now. If you are allowed to open the can, it sometimes helps if you true the commutator with very fine sandpaper. Sometimes the tension on the brushes are too low or the brushes need to be replaced (sometimes with a larger version if allowed). You may want to experiment with that as well. As for the motor themselves, I found that there is always one or 2 gems among a batch of ten or so.
Have you tried discussing this with your race official? It sounds like your problem is very obvious since closed can racing should make all cars fairly equal in a straight line. Perhaps you could explore the possibility of each driver buying the motor from the track just prior to a race ( a new motor that has been broken in) ..... then relinquishing the motors after each race and then draw from the same batch for next race.
Excelent idea. That is what I was discusing with a guy on the phone this morning.
The track owner should go through each motor as I stated earlier to get each one equal and then hand them out before each race. Like picking a # out of a hat and turn them back in after each race. Everyone have same gear ratio also.
I have talked to the track owner about it only to be blew off . His majority racers have these hand grenade motors. He doesn't realize that he isn't making a dime on these motors. Slot Tracks are a mean buisiness. He'd rather loose me and a few others rather than loose the Outlaw bunch.
If you choose to try and tweak and you want to keep the can closed, then experiment with the brush tension and brushes. I have seen big improvements just by increasing the spring tension. However the motor will run hotter.
