I am running 48 pitch gears in a Tamiya 415MSX MRE and I was looking for a sixty tooth spur or 38, 39, 40 and 41 pinions.....

I switched my TC4 and TC3 over to 64 pitch. 88 spur works great, but i may check into something a little smaller.

I am curious how many of you guys are running motors below 100 degrees. The lowest I get after 8 mins of runtime is around 125 deg F. If I read the temps on the top of the can where the sticker is i noticed temps 120-125 deg F. If i temp in the area where there is no sticker I get really low temps like 88-95 deg F. I noticed that its the shine of the can that is throwing off my IR Thermometer.






Are you guys getting your sub 100 deg temps from a part of the can that could be possibly giving the wrong temperature?

My set up is a Cyclone TC, FDR: 3.55 , Cirtix Club Racer esc, Cirtix 17.5, ambient temp of 68 deg F.

Just curious because i noticed a lot of guys mentioning how cool this system runs but it seems about the same as any of my other stock setups.

Silver colours will not read properly with an IR temp gun. You need to put a pice of black insulation tape or duct tape on an area where you will be reading to get a good accurate reading. Or, find a piece of black or dark label that isn't metallic

The silver or shiny sticker will give you different temp readings as will the top of the can versus the bottom or end. I generally will check the motor at 3 different places, (not just SP 17.5R). If I think the reflection is giving me a bogus reading then I will put a piece of non-reflective tape on the can and then use that spot to check my temps.

Okay so I finally just switched to 64 pitch gears. Seems like the easiest way to go!!!

I use a raytek laser temp gun. super accurate after our last club race I zapped most of the cars around me in the pits(aprox 5 cars) and all were in the 126 to 155 deg temp range depending gearing. the hottest part of these motors seem to be right in front of the wire harness on the top of the motor. that is where i do all my temping now. i run a 3.67 and most were geared at 3.4 to 3.75.
the temps were after a 8 minute run in RCGT mine was 137deg
our outside temp was about 89 deg. F , at night. hot and humid

Ran my car with the Cirtix system at the first race in OC Circuits series. I must say this speed control/motor combo rocks. Some of the guys were very close in speed to the regular 17.5 class!! I geared at about 3.4 on a large track, and It was very nice!! I am sure I could have geared up a tooth or two, but I wanted to play it safe, being the first time I ran the combo!

Default SP GT2.0 stock

Does anyone here know how this ESC compares to the GT2.0 with the Stock 508 no timing software on it? Would the FDR's be about the same?

Thanks

The GT 2.0 will be smoother and cooler because of better hardware. Depending on your motor, the FDR is pretty close.

Thanks for your help, I think I'm going to run a 3.7 on the GT 2.0 with the 508 software.

finally got to get a good run in with the 17.5 combo this weekend.
im running a 3.72 fdr in my tc4 and i got 60 degrees each run (2 decent length runs around our local track)
that converts to 140f i asked the other guys what temp their motors usually run at because i was wondering if this was high (after you guys saying you were getting about 110f) and they say as long as you are under 70c or 158f you are fine, is this true for the speed passion too?

as for speed it seemed great! im completely new to the touring car scene and im fairly new to RC in general and my mate with a new advanced timing hobbywing wasnt catching me around the track!

Hey guys, I had a chance to race mine Friday night and it is a very smooth and linear combo. I had my car geared at a 3.8 and found temps around 180f, track temps were 130f and air temp was 109f at the start and dropped to 95 by the end of the night. I would recommend this system for a club as it has been reliable and efficient for me for app.25 packs...
