I am scratch building some new cars in 1/24 scale. I want to use the parts from some D132 cars, like the motors and chips. If I use the control unit to reduce the power to these cars down to 60%, I think it might be OK to run them. But one time I put a 1/32 car on my 1/24 powered track and something burned up in the chip. It could have been because it was a defective chip or I had something wired wrong, but I want to know if this is OK before I put a lot of work in to this project.

I am building about 6 cars like this in 1/24 scale and want to run against the 1/24 GT-40 cars that Carrera makes.

So does anyone know if this will work or will I fry my chips?

My curiosity got the best of me. Running a 1/32 motor on the 1/24 power at 80% power worked fine. I think when I burned out the other car it might have just been the motor that fried and not the chip.

We recently ran on a 1/24 big wood oval 6 lane track with our chipped 29k slot.it powered 1/32's, he had it cranked to 15 volts 4 amps per lane, knock wood,,, didn't blow any chips after 4hrs but they did get warm, he runs 1/24 parma womp cars. Have had stock motored Carrera cars brand new smoke a chip in 10 laps out of the box on our plain ol roundy round 4 80' 4 lane Carrera track. We also have guys with cars over 2 yrs old of hard running with big 40k motors never have a problem.

We run 18 volts for D143 without any problems. Should be fine for 1/32 & 1/24.
