For a friend I did take the gearbox apart but could not find a reason so I suspect the springs are maybe temperature sensitive.

Maybe it is already solved in later production series.....

Ok, so here's my findings in comparing the Xray gearbox springs to the Kyosho:


Height :6.80mm
Dia: 4.53
Number of Coils: 4
Color: Silver
Coil thicknest: 0.60mm


Height :7.00mm
Dia: 4.83
Number of Coils: 4
Color: Black
Coil Thicknest: 0.70mm

The tension bolts are exactly the same.

So considering the shift point problem with the Xray, I will be using the Kyosho springs instead. It fits perfectly!

Will keep you all posted on the results.
