I have two of these models. Both have suffered the same transmission problems. The carden shaft is made of steel whilst the two transmission lugs on the shafts are plastic. I found that these were spinning around the shaft and therefore not transmitting power. My solution to this was to rough-up both ends of the shaft and superglue the plastic lugs. I also took out one end of the gears & removed the carden shaft. Its a bit fiddly, and I had to cut two wires to get to the bogie, then re-solder the wires in place...but its been worth it. Both run perfectly; faster and slower when needed. I feel that there is less snatching & undue torque with more control on the motor now... but you need time and patience to do it. Dapol would do well to change their design and replace the carden shaft with a solid plastic type, like Bachmanns, and to re-gear to a single bogie on the Bubblecar.
