Default Mod racing with T2 009

Hey guys got some modified racing coming up and was just wondering roughly what a good roll out is to aim towards with a 5.5t Novak. I was running it yesterday for a few minutes with 26 degrees positive timing programed into the ESC (not using a sensor cable so no timing in the motor due to motor playing up when using sensor cable but works fine without it) with 24mm rollout and it got to hot to quickly for how long I ran it. I since have put the timing down to 18 degrees timing and havent changed the gearing.

Ill run it again this afternoon but if it runs cool/hot with the current setting what would you recomend to change? (timing up/down or up/down in gearing) Obviously I would like as much speed as possible with the motor still staying under 75-80 celcius after 5 mins.

Also Ill be running it in the day which is generally around 25-29 Celcius so I have to allow for that aswell.

Thanks for any advise or help

Wat the hell! Ive got a 86 tooth on there at the moment and if I went any bigger it would sit out the bottom of the chassis and scrape on the ground. Even with grinding dont know how you managed to do that!

I'm pretty sure his 118 is 64 pitch and your 86 if 48p.

Aim for FDR ~ 8.5 to start, so if you use a 86 spur, then try a 19 pinion to start.

Yeah thanks for that. I started at 8.5 FDR but have been told by a highly experienced Mod racer to go for between 7.5-7.8 for the track and weather condition we have here. And if use a 19tooth with the 86 tooth then I get 7.69, not 8.5 as mentioned above. So ill try that and see how I go. Thanks

u must be using internal ratio of 1.7 instead of the more common 1.9. If your track is large with flowing corners, then u can gear it more aggressively.

moreover , for mod motors , u dont want to add too much timing to the motor and the esc. too much timing will cause heat but the car will not go that much faster. it is better to put less timing and play with gearing.
