How smooth are these motors compared to the D3 and the X12 17.5's.

Whats the ''gauss on a the rotor''......

Ran this motor yesterday boosted. Ran very cool and was very fast. Power was very predictable and I would say it was smooth. I had my delay at .5 I lowered it to .2 which made the car even easy to drive on my track. At . 5 the boost would kick in at two locations on the track where it was not wanted that late. Still messing with set up but so far very impressed.

I've been running this motor for the past 5 practice sessions and a few races.

17.5, no timing with the Blue Mid-torque rotor. Motor timing at 34 degrees and FDR at 3.541.

I was running 3.674, motor temped at 125 after a 7 minute run then I bumped up 2 teeth to get to 3.541 and now I temp out at 140 after 7 minutes.

Track is West Coast RC, high grip asphalt. Lap times 13.9 avg.

Anyone have any input on gearing with the torque rotor? Seems the standard rotor likes to be at 4.1 or so FDR...is this normal to be a 3.5-ish with a mid torque rotor?

The gauss is the magnetic strength of the rotor, you can use a piece of equipment to see how much magnetic strength it has.

I run a Black Diamond speedo which doesn't have turbo etc, so I need high torque rotors.
If you have a speedo with turbo etc. it isn't as important as you can make the motor rev using it's settings.

Is anyone running these in boosted 13.5 with a Tekin? How are they performing?

Default Z3R

Ran a 17.5t Z3R with +40deg timing with a non boosted firmware hobbywing Xerun esc on a Xray T3 with a rollout of 55mmpr. Car was super quick on the track! Motor lasted about 10 races of 6min, usually came off at about 70-85 deg c but decided to go up in smoke. Personally I dont think +40 deg is to far advanced, is it????

85c might be a little pushing it.

I am running on a Carpet Track Similar to the Snowbirds Setup this past year. What 17.5 Thunderpower rotor does everyone suggest for 17.5 Boosted? Also, what gearing with that rotor would you suggest?

+1 85c (185F) is a little high. I try to keep keep my motors under 165F. I have at least 10 race days on the same 17.5 stator. what is your FDR?? sorry rollout doesnt mean much to me because all tires tend to have different diameters. I never run more than 37 degrees of timing either. What rotor are you running?

If my backwards math is right, you're running about 3.1 FDR which is high, you might be able to pull it off when its cool out, but I would gear up to about 3.5 and see if you actually loose any time, or take out 10dg of timing.

Thumbs down Thunder Power Z3R

I have not had nothing but bad luck with this motor. I'm on my 3rd. one and I have not over heated any of them. 2 Laps and up in smoke, they go Faasssst when they run but the races are 5 to 7 min. long. I started with a FDR of 3.9/ 20* timing, fast it was. Bumped timing to 30* FDR 3.88. on pace with the winner. Non boost Class. Sending it back to Thunder Power again so they can put the smoke back in it for the 3rd. time. LOL missed my main again.

Maybe try gearing up without adding so much timing in it? It sounds like most people are sticking around 20 deg of timing.

Hope that helps!!!

What up Web, long time no see, not sure if you have been to WC lately but if not they did manage to change some of the bulbs over the track so it's much brighter now. Yep Korey is correct, I too think the issue is with you adding mechanical timing to the motor while gearing up at the same time. You could also try either our green or blue rotor as well if you want to add gear and timing. But they seem to run best around 20*.

Default Z3R 17.5T with boosted ESCs

Hi has anyone tried the Thunder Power motors with a boosted ESC in 17.5T class? Would like to know how well the motor reponds to timing.

Thanks.

Mike Haynes won the 2011 Snowbirds 17.5T boosted class w/ the TP motors -- i'd say its good
