Been toying with a TSR 13.5 I picked up 2nd hand, at the moment, on a large outdoor track I'm at 40 degrees endbell geared 2.93 FDR 3 Stripe rotor, not even getting warm, 35-40c but a little bit of fade after 4-5 mins. Where do these want to sit?

Have you tried the 4 line rotor?

That's alot of gear for a 3 line rotor.
Have you tried less gear and a few degrees more timing or dropping to 38*?

Just got my 17.5 the one

Switching from Trinity and super pumped. Question, my new Tsr rotor has zero play as I got it.. I am so use to shimming rotors to my desired wants but was hoping to start with my TSR out of the box.

SG1 do you think I should take it apart and re shim to have some play before I start running it? Thnx in advance

It sounds like the bearing didn't seat.

Hold the can in your hand and gently tap the pinion shaft on a table

With brushless motors only a tenth... brushed motors 2 tenths...lol

Picked up a used 21.5 what sort of starting area for a very large outdoor track (I gear the Trinity Monster and Fantom Type T 21.5's at 2.78 FDR around 50 degree actual timing)

Data from the bench so far:

Team Scream 21.5 Motor (TSR The 1 first version 2nd hand bought $60 USD)

3 Stripe Rotor

Igauss 1420/-1439 (Using Trinity I-gauss meter)

Stator Resistance 33.8/33.9/34.1 (Using Racing Machine Systems MM2 Meter)
Stack Length 19.4mm

How large of a track is it??

That's alot of timing and gear...lol...

That 3 line rotor seems pretty weak. Typically they are mid 1500's on an I-gauss.

Maybe try slightly less timing 48* and less gear to start. I'm not sure that rotor can pull that much gear.

I think a lot of people now use a fantom facts checker or similar to check gauss ratings, I find the older i-gauss is usually 100-200 less than those on most motors.

For example

Fantom 21.5 Pro Select Rotor (Kept Race Motor)
Actual Timing 48 (44, 51 49) 4.5A 22686rpm 2835kv
Rotor 1365/-1346
Stator 34.2


And that motor happily pulled FDR 2.76 without getting over 120-130f

If anything at similar timing I need to gear this a bit harder, lower rpm and higher gauss rating

Timing Set 48 (47/48/50)
2474 kv 4.9A (18557 rpm)


But a loaded dyno run is next.

I like the Trinity I-gauss

I didn't realize the other rotors were weaker.

I use a 9.5v power supply with mine, I noticed when the battery drops so do the readings.

Let me know how the dyno test goes.

lol..

I ended u taking it apart and pressing the bearings with my Much more tool. Still tight but it seems dependent on how tight the three can screws are. I backed them off slightly and gave me some wiggle room.

Tried the motor yesterday in my typical 17.5 and even run the same car in mod and it was flawless in both classes. Great motor, literally screams and put's out lap after lap. Ended up running it at 40+4 notches - 40 + 4.5 notches which put it at 5.6-6.2 amp draw off the top of my head with some solid 26-28,000 rpm pulling range

Thanks TSR for a great product. Need a 21.5 for my Usgt sooner then later

I am borrowing a new 25.5 TSR from a fellow racer that I am going to run in VTA. We have a small track. I have been running a 24K with 3.87 gearing.

I tested last week a 3.88 then bumped to a 3.96. Performance was OK but I would say the motor felt a little flat pulling the infield and off the corners. Top end was fine. Not sure if I should tweak gearing or timing. Motor came off at 140 degrees.

Chassis is an Awesomatix A800

Where should I start with timing and gearing on the 25.5 TSR?

At our track we are 88x40 and we run 42 to 44* of timing at a 3.5 to 3.6

If you have a much smaller and tighter track and a 3.96 felt soft off the turn you may have too much timing. Where is the timing set to?
