Back in June my son and I started running in The Porsche Cup Cars, which uses the kit torque tune motors. Yesterday was our latest race and we were in top place for the A main. My car died right after go.

The torque tune called it quits and spit out one of the brushes which buried itself into the tub lol. Motor has a fan and the case / end bell temped at 100°.

My son finished the race in first but also told me that his car faded at the end of the race.

For gearing, we were running 64/29 the max per TT02R manual, using Tamiya mod 06 / AV gears.

For Tamiya ProSpec class it's not an issue with the 21.5. For CupCars using the Torque Tune I’m surmising that it’s too much gearing.

I took a peak at the TT02R manual and noticed Tamiya had highlighted 64/27 as popular. I’m guessing that could be the max with this motor? 🤔
