A while ago I purchased a Boomerang from Flo.
Yesterday I fitted new wheels and tires for now.



First part task is to see if I can restore the wheels.
Tires is hard as solid plastic so they was no hope for


Tires was easy to remove, cut a knob of and cut across tire with a flush side cutter and then peeled like a orange.


After 24 hours in grafitti remover, 99% of the paint was gone.
I did scrub them several times with cotton sticks during that time.


Only one outer ring was good enough to keep so I decided to sand them off. What a mess!


My el chipo lathe lol!


Also did the backside. The outher ring was good enough to keep.


That is how far I managed today.
 

Luv the lathe.  I've done some small scale stuff with Dremel 

Forgot I had a thread on this...

As you may have seen I have done a few snowruns with this the last few days.

Today I wanted another run before the snow turns to slush.
Was -10C today so both my body and the Boomerang was not happy due to the coldness. Yesterdays -7 felt warm compared to this..
But the car was nearly dead at 7-8min mark, should go for 30min easy.

I had two suspects.
First the on/off switch which was very easy to slide, like no snap stops.
Suspected due to this there was a consumption loss, so I swapped it out for another one.

My next suspect was the vintage Kyosho K-Speed 21T motor I recently installed.
And there it was!
Brushes was nearly completely gone!


Here is the motor


Cleaned and installed a set of these.


My lipo alarm says 7.80V still left and now the motor works good again.
I will also order some bearings for the motor.

If you missed it, here is the driving video.
