Hi All,
I am new to HO drags racing. I have spent most of my slot car time on 1/32 digital. Recently though I bought an HO set with 4 gear drag cars. One was going fine until I held the rear tyres up of the track to warm the engine to see if it made any improvements. As I was doing this I noticeably heard the revs drop and they wouldn't go any higher than mid range after that. The car was slow where it had been quick before. So I changed the brushes (not knowing what else to try) and it is fast again.
What would have happened?
Also, I bought an XTraction car which was going really well straight out of the box and keeping pace with my fastest (all non modified) 4 gear Mustang. It did about 15 runs and now it is also slow. Not super slow like the car mentioned previously but instead of matching the Mustang's pace it finishes about 10 inches behind every time.
Is this normal? Do you have to replace brushes constantly? Is there some simple maintenance that will help? I know people speak of lubricating the armature and I presume they mean where it's shaft fits at each end but is there something that will keep the brushes alive? What would cause an instant drop in performance like this?
Any help, much appreciated!
Cheers,
Damo.
