First let me preface this by saying it's now going 8.5'/s
OK last night I got some answers, but it's still not clear. The original setup had the 2005 motors in it, and transmissions assembled such that they made a little noise but not bad. They weren't greased yet. Just a student slapped together out of the box kit. But from a distance it all looked right. So we performed the tests and it ran slow - 5'/s.
Over the last few days we removed the 2005 cims. Milled and faced off some gears and Also added a gear to mate with the FP's
Then installed cims from 2003 and 2004. They now weigh 8.5 lbs with motors.
Last night I tested the output voltage to be 12v
then we put a zip tie on the wheel letting it whack a piece of plastic so it was loud and ran it for 20 seconds (up on blocks) with a stop watch. I counted in 4-4 timing marking on a sheet while keeping the beat (I gots rhythm). I counted 108 revolutions/20 seconds x 3 = 324 rpm at the wheel (and I got the same results twice). Which on a 6" wheel works out to be 8.5'/s
So what happened?
I did notice the students had the gearbox assembled incorrectly "After" the mods. So it's possible they we're incorrectly assembled prior to this and during the original testing. Also I saw that the cables were all hastily crimped loose and the connectors were not screwed tightly on the controllers.
Analysis:
1. Either our 2005 kit cims are bad.... Nah...
2. Our transmissions were assembled incorrectly.
3. Teenagers in a hurry wired it up.
Answer:
SLOW DOWN YOU CRAZY KIDS!!!!
Why are teens always in such a big hurry? Where's the fire? Why does everything always have to be done in a nanomicrosecond?
ok off my soapbox
After all this, we don't plan to use these on our competition bot. But it's turning out to be a great sparring/practice system.
