Yup,
13.5ss in mine.

What about 17.5 ?

Yeh , ive seen one run , fantom version , looked very fast . I have no idea what ratio they were running though .

Not sure on that really,
I know a few racers that have ran a 17.5 in a wheeler, but that was for one race event. No idea what gearing they went with either. Most racers I know that run 17.5 2wd run 13.5 4wd for stock buggy racing, which is what I usually run myself. That seems to be the norm for the stock buggy classes for the most part (at least for the general area/region/tracks I usually run at). Only race event I know of that does have a 17.5 4wd buggy class is the OCRC Stock Nationals I believe. Might be other places that have that class, but I'm going to say I think that would be more of the exception vs. the norm.

I'm from Australia and our stock off road class is 17.5 for 4wd and 2wd. I have tried running the ss in my yokomo bmax4 and have had overheating issues so was seeing if anyone had some success with them.

Ok got ya,
Let me see if I can find some info on that.
Do you run a fan on the motor? I'm betting you'd almost have to in a wheeler.

I'm from New Zealand, i run the 17.5 short stack version in my losi 22-4 and 22 2.0. our races are 6 minutes + final lap, i run it around the same gear ratio and timing in both ( around a 5.5 FDR and 58 motor timing). I do run a fan with it as it does get hot, but have been running this set up for about 6 months now with no issues. If you visit countiesrc.co.nz you can see the type of track i run on and lap times in the race results

How have u mounted the fan in the 22-4 ?

Ok cool. Yeah im running a WTF windy fan but it still heats up so much what spur pinion are you using exactly BKH ?

And do you think you are loosing punch due to the heat of the motor towards the end of your races ?

My car pretty much dies on the last lap of a 5 minute race man it has cost me some wins lol

I'm using 78 spur 32 pinion which gives the 22-4 a 5.6 FDR, my motor usualy comes off around 60 degrees celcius ( 140 F ). When i first started running 4wd stock i had quite bad power fade in the last couple of laps but was using cheap low C rating batteries. I'm using Orca 4800 100C shorty packs now and that seemed to solve the problem.

is a certified version worth the additional $50. Anyone who has one able to tell a difference. The only reason Im looking is, I just burned out a sensor board after one day of use on my d4.

The sensor went after one day? What was the after run temp?

buy a new sensor board?

It was coming off around 160. Never higher then 165.

[QUOTE=RC*PHREAK;14144537]buy a new sensor board?



I did that as soon as the issue happened. Still, for 50 dollars more I'm wondering if the certified motors are worth it. After I replace the sensor, I still have to buy another motor for my sc5m, so I was gonna put the rebuild in my sc and possibly a certified or normal d4 back in my yokomo.
