How big is your track and what surface?. I basically see that the 21.5 and 17.5 motor fdr's are usually pretty close.

I'm running a hobbywing V3 with my SchuurSpeed 17.5 with a high rpm rotor for boosted.

Let me note that I'm running this setup in my 1/10 dirt oval EDM.

I'm running mode 7 stock 17.5
1A. Forward/brake
1B. (3) reverse speed 75%
1C. (5) voltage cutoff 3.2v
1D. (1) esc overheat 85*C
1E. (4) motor overheat disabled. SchuurSpeed motor temps don't register.
2A. (50) punch switch point 50%
2B. (30) 1st stage punch rate max 30
2C. (30) 2nd stage punch rate max 30
2D. (1) throttle curve Linear
3A. (11) drag brake 10*
3B. (9) brake strength 100%
3C. (1) initial brake = drag brake
3D (50) brake switch point 50%
3E. (20) 1st stage brake rate max 20
3F (20) 2nd stage brake rate max 20
3G (1) brake curve Linear
4A (51) boost timing 50*
4B (10) boost start rpm 5500 rpm
4C (29) boost end rpm 17000 rpm
4D (1) boost slope linear
4E (2) boost by throttle no
5A (1) turbo timing 0 degrees
5B (1) turbo timing activation full throttle
5C (2) full throttle delay .05 seconds
5D (10) turbo timing start rpm 17000 rpm
5E (2) turbo timing engage slope 6 deg/0.1 sec
5F (3) turbo timing disengage slope 18 deg/0.1 sec


I'm not sure how these will work with on-road but its pretty decent on the oval. Now its indoor season so the tracks are smaller. I would add turbo for longer straight away outdoors tracks.

Hope some of these help

Roger

Just a note regarding the timing. This motor zero timing is actually zero, and many motors zero can be any where from 28 to 34 degrees. You mention LRP and the 2 dot which is approximately 32 degrees.

For 17.5 Blinky start at 36 degrees timing and gearing will depend on the weight limit your using, along with the track size.

To answer the heat question there are several items to discuss. The first is that this motor will typically run 15 or more degrees cooler than most others. So if your gearing for motor temp (which i do not recommend) more than likely your past the optimum performance gearing/timing. As stators (any brand) get hot the resistance of the copper wire increases, and performance drops. Racing in southern california is not unusual that our ambient temps are over 100F in the summer months and after a run motors will come off the tracks from 160 - 185 and experience and results show we have done extremely well.

If you have support questions I actively support through email, both inquiries from the website and direct through support @ schuurspeed . com I welcome calls but am often at a track and its difficult to hear at times so email is preferred.

I appreciate all your support and look forward to assisting as possible.

Hey Roger thanks for the assist!

Yes as I mentioned in a previous post the timing comes at 20 Degrees, and we run each motor prior to packaging. Zero was set to zero as some racing requires motors to be run without timing.

But for the other racing purposes this is not the best place to begin and is vehicle and track dependent. But a general rule please increase the timing to at least 30 degrees for any blinky or non-boosted racing.

For example for 17.5T I'll list some starting points:

2wd SCT - start with 32

2wd Racing Truck start with 35

2wd Buggy start with 38

12th scale start with 30

10th Touring Car start with 38

Again if you have questions please email support @ schuurspeed . com for quickest reply.

That shows the track and size I run at it's a very large flowing track

our VTA Weight limit is min 1500 grams (as we don't run driver figures)

I am running a Serpent S411 TE with Exotek deck

On that size of a track, I would start at a 3.4 fdr and timing at 34 degrees or even 38. I could see the fdr going down a littler further because it looks like you can carry alot of speed through the corners.

that's good info, thanks Ron.

just curious what you might suggest for 13.5 blinky for 1/12 and wgt? there was an earlier post about 36 for wgt. would you try even more timing than 36 for 13.5 1/12?

Thanks Ron. Can you share some points on boosted 1/10 TC 17.5?

Thanks

With the stock rotor being a long 12.5mm high torque, you should consider increasing rollout combined with the lower timing OR you can certainly bump up timing as high as 38 without the increased rollout.

For Boosted 17.5 TC start the motor timing in the 20-25 area to start off. Then adjust the amount of boost and rate of increase, with Turbo to give you some kick down the straight.

The motor comes with our high torque 12.5mm rotor which is really suited for Blinky racing. For boosted you may want to consider a 12.3mm long rotor, or our short 12.5mm rotor for better RPM.

Default bearing sizes

Hello,

Can you supply the bearing sizes used in your motors?
I cannot locate this information in the product specs.

Thanks

The V2 motor can not be run at zero timing.

For On-Road you'll generally be above 35 degrees timing. If you could contact SchuurSpeed at [email protected] with details they'll help you sort through this.

I am running my schuur speed 17.5 and 13.5 in my Tamiya 419. It has run very cool at 120 degrees after a 6 minute race at the Tamiya USA facility. I have great bottom end rip and plenty of top end.

I gear the 17.5 at 3.5 and the 13.5 at 4.3 Fdr. I do run a fan on the motor. I run the hobbywing v3.1 speed control. I run 40-45 degrees of timing on the motors.
