I have for sale a gtb speedo.
It was used in a B44 but then changed to a losi22.
I reset the speedo and the reverse stopped working but forwards was fine.
I don't have the manual to go with it hence i have been unable to get it working correctly again.
The cap leads have been extended to fit my 22 (on motor cover).
