Question: Hi Prof. When I pick up my re-re Boomerang off the floor and run the motor, the front wheels and arms bounce up and down quite madly! I have tried swapping drive shafts fton to back and have made sure my bearings are seated properly in the wheel hubs, I've also double checked that the monoshock is installed properly. I've run out of ideas now so am turning to the God of vintage knowledge in hope.....
 

The wise one answers:

Hmm a number of possibilities. You could have a bent drive cup or buckled wheel. Try it without wheels on the front. If it still does it then you've eliminated all options really apart from the drive cups/axles?
