I dont mind that the tread is a little off track, I want to make some rewinds for my four gear cars anyway. Sooo... back to the stuff at hand... gotta get back to the rewind at the bench.

Yea sorry about that I may try to do some rewinds myself. I have some wire available and a balancing
tool.
There was some challenging going on and we were discussing it some. They want me to come and play in their playground. Might just take em up on it but the time to redesign a chassis is short for the next race.

I don't remember any of the 2 gear inline FED hybrids making enough noise in this class for me to want to change from the 6 gear builds that the class is based on  Do you mean a 6 gear is going to be competitive with my 2 gears? |

What Sam is talking about is my failed attempt at putting a can motor in a 4 gear chassis. It was fun to try but never really worked but I hadn't really giving in on it till it got outlawed.

Peter Yes that screws up all my hot arms since the timing is different as the extra gear causes the need for reverse rotation.

Does anybody know if Wizard dyes the wire after wrapping their green wire arms ?
Sounds stupid to me but heres why I ask. I stripped an arm today that was giving me fits getting wire off of. One clump of wire changes color from one end to the other , green to copper. Under magnification it look like insulation is dryed and falling off. Just came to me perhaps arm was smoked once. Got it in lot sale, both brushes were broken and when replaced car always overheated fast. Buy arm did still run.

Sounds like it was overheated. I have seen some wire that just flaked off from too much heat.

Thinking it was overheating......... lighter color green dust was present. All the wire seemed as if bonded together. Like each pole was wrapped with a solid piece of wire. After using cut off disc to remove end of wire bundle. Stood arm upright by dropping shaft into hole in wood. Then used small screwdriver and a hammer to drive tip between stack and wire. Did this on each side of all three poles. Could not remore otherwise. Already tried every thing else I could think of. Never saw this before, perhaps just not to this extent.

Well, the rewind is 2.9 on all poles, and it runs. I popped it into a beat up four gear, it runs. Now I need to go through the chassis and set it up for some higher amp draw... this arm was quite noticeably faster than the 6 ohm Tuffy arm it replaced. Now I need shunts, stuff, more stuff...  |

Peter I have seen that and it happens when an arm had been run with severe drag on it. Melts it into one piece. |

Just used that link again.............
Wound pancake with 34g wire (36 was covered). 5' on each pole 90 turns apiece. Using resitance link : 5' of 34g wire is 1.305 ohms.
LETS MAKE THIS A GAME !
WHAT DO YOU THINK THE ARM WILL OHM AT (pole to pole) ? When soldering is done. :-)
