You over geared it. We had to drop 2 teeth 64p with our cars ......

 

Spur or pinion, or both?

Maybe .047. Many start the race with .690 tires. What do you think about 12/38 64p?

I built a 4.5" stock car with one yesterday. Geared it 12/37 64p with .790 tires and it runs really well on our 155' Hillclimb. It is fast, has good punch, but brakes were soft. Going to try an 11/36 next, but it is very easy to drive as is.

What gears are people running with this motor in something as heavy as a 4" Flexi? At the local track we've been struggling a bit trying to find a ratio that the motors consistently survive a race. We're also noticing significantly more brush wear than the 4002fk that we've been running. (Please don't take that as trash talking ProSlot, just looking for some answers.)

 

The track is a G4 Gerding King, and we're running 4" Flexis with various bodies. (LMP, DTM, Nascar, etc.) Tires are Wonder rubber, up to .760 diameter, and we're running 64 pitch gears.

My wing guru, Michael Iga, ran one on my King 3 Wednesday's ago, in his Group F wing car.

It was geared 11-40, 72 pitch.

The motor ran icebox and the comm looked great.

Lap times were like a good 4002FK.

Michael said it was wound out before the Bank.

We skipped last Wednesday due to the Sano, but came back this past Wednesday to racing.

He was geared 12-40, again 72P.

More bank speed, still good low end.

Michael ran a lap or two off of the lap total record which wasn't surprising since the track was in great condition from the Sano.

The motor ran warmer, but by no means hot.

A few times between heats, I put my finger on the laminations of the armature.

I wouldn't want to leave it on there for any length of time, but I was able to touch it without a problem.

After the race I went out on Orange, and full punched, I went 15 or 20 laps in a row 3.12-3.13.

I finally stopped when I ran a 3.141.

One thing I noticed is the comm started to get a slightly weird comm track on it.

I'll try to describe it in a little graphic below, but it was almost striped, where there was a great looking comm track patch, and then there was a less great looking one and then back to great, almost like tiger stripes.

G4 Gerding King, 13.6 volts, running 4" Flexi with DTM bodies. Tires are Wonder rubber, .760 diameter,  64 pitch gears (10/36), 2 minute segments.
My new Speedball almost made it thru 2 whole races before it went up in smoke. 3 other racers had the same thing happen tonight.
I'm DONE with the Speedball!

Why did they go up in smoke?

 

Had they been prepped in any way before racing?

You will have to ask Pro Slot.
We have had a much higher failure rate with the Speedball vs the discontinued Pro Slot FK4002.
As far as motor prep, some run as is, some change springs & brushes.
When I pulled mine down, the brushes & comm looked OK; the arm was cooked.

Bobby,
Was the 9000 motor, at 10-36, faster than the 4002FK at whatever ratio you ran it at?

If so, I suggest trying 9-36 and let it sing.

We've only had 2 on my King, but they have run well.

As mentioned, my King is 13.6V, and I am fortunate enough to have real high end, well filtered, power supplies, which seem to be easy on motors for 13.6V and 10-10AWG, staggered, positive and negative taps.(IOW, 20 total)

Yes the Speedball was .1-.2 tenths faster than the 4002.

 

One of my fellow racers geared his brand new Speedball at 9-37 and only got 7 segments out of it before it burned. He tried another at 9-37 and got 10 segments before it burned.

I can't speak to the power set-up on our local track, but we can see a real difference in the longevity between the two different motors, running on the same track power set up.

I might add that some racers are still running leftover 4002FK's in the same races as the Speedballs, without issues...

Tore down my smoked 10-36 Speedball. I'm no expert, but it looks like it threw a wind...

Could be a less than ideal epoxying job at the manufacturing facility.

Man I don’t think over ever seen one quite smoked like that
Did the fire brigade have to come and put it out?

The epoxy is destroyed by high heat
I’d say the arm shorted somewhere
