I had a good old test run of both cars, or basically the bodies and chassis without the interiors over the last few days. From the box the slot it Datsun was faster than the Revoslot with original tyres etc by a fair margin. 
So I decided to upgrade the motor on the Revoslot to a 35k rpm SRP short can….which made quite a difference and narrowed the running difference with the Slot it quite considerably. 
But then I thought to improve the Slot it Datsun by changing the motor to a Flat 6 25k rpm and change the tyres……..now I have the same difference as when I started 

I like a challenge so I will see what else I can do in the new year with the Revoslot version.
