Really enjoyed our first year racing the M05's. Considering me and my lad hadn't even used an RC car before we were chuffed to end the year in 4th and 5th respectively for the local league outdoor.
Anyhow we seem to have dropped right off the pace indoors. Our cars were fast outdoors but all we seem to be doing is fighting them indoors. I have raised the ride height on both cars. We have fitted mini pins which seems to be the choice tyre (Polished floor, village hall type thing).
I think I know the problem but want advice on the solution. I fitted 3 racing geared diffs to the 2 cars in the summer. Mine even got thicker oil to make it stiffer but in comparison to the stock diff our cars are way stiffer. This isn't going to be very good indoors.
So do I put thinner oil in both diffs? If so how thin?
Or do I just put the kit diff back in. It seems to work well enough last year.
Any other suggestions appreciated.
How are you fighting them? Sounds like a serious lack of traction to me... polished floors?
My MINI racing experience is all on indoor high grip carpet. The initial struggle on this surface is a car with too much entry steering and traction rolling issues. Eliminating rear droop and ensuring zero bump steer solves most guys initial issues. Never forget to CA your front tires side walls too.
As far as your diffs... I have run open diffs all the way to very thick oil filled.
In your situation I would think it 'safer' to run the stock open diff. With a lack of traction a thick oil filled diff could make your car a handful.
And also, ask the fast guys what they are doing. I should hope they would be very helpful getting you up to pace.
I hope that helps.
