We have a problem whit the speed 300 motors (graupner).
The previous batches used to last for about 20 runs of 8 minutes.
The last batch we bought lasts only 3 to 4 runs. After that al the power is gone.
We tried this whit 4 motor. Al had the same life span.
The only difference I fount was the marking on the can.
The first batch was marked: Made in china Mabuchi 05 (green text)
The second batch was market: RK 370SD_5028 TD096Z19 (grey text)
Someone knows this problem?
Is there a solution for this?
