Default Reedy Mach 3 17.5 1C SS Tuning Question

Hi,

I recently purchased the thread title motor. I ran it last night for practice for the first time and had a couple of questions on how to get the most out of it. My gearing is currently 69/32 with a timing of 30, after 5 - 7 minutes the motor was around 140 degrees. Some people at my track have told me that the reedy likes to be around 170 degrees. What are some of your opinions? I can fool with the motor myself but would like some insight so I'm not wasting my time or potentially causing damage to the motor itself.

Thank you

I run mine in a 2wd buggy with the timing set at 42 degrees on the can (41 actual per motor analyzer). The track I typically run at is a tight medium bite clay layout where I run 31/69 gearing which seems appropriate. My practice sessions are usually 10 minute runs where my motor comes off the track at 125 degrees F consistantly.

My measured free spinning current draw at this timing is around 1.8A. I don't have the numbers in front of me but I seem to remember 44 degrees on the can having a free spinning current draw of ~2.15A. I wanted to keep the motor cool for my longer practice sessions without using a fan so I decided to keep the current draw lower. I believe for my motor ~44 degrees was about the ideal performance timing.

Personally I think 140 degrees is a good temperature to run at, I wouldn't run up at 170 but that is based on my preconceived opinion. Others may have experience that says running consistantly at that temperature is fine for the M3's.

I run mine with 69/34 gearing and 20 deg timing at 150-165F. Clay track high to medium .
bite. Fast in the straight and a lot of torque to clear the jumps.

I run mine at 42 degrees of timing, 12.5 rotor, 47/96 on my TC7, comes off at 120-125 after 10 min
