Omarko, Freestyles etc. Don't worry. There are lots of set ups for these cars around now. For all kinds of conditions too.
Firstly, and my apologies go to those who already know this:
It all starts with a good build of the car!!
Ensure suspension parts are free to move and do so smoothly and without binding through out the parts FULL (!) movement.
Make sure, on assembly, there is no "extra" slop in parts. The top front A arms are renown for this. Also the axles. Get rid of as much slop as possible with out creating any binding any where.
Ensure when the suspension moves, the shocks start to move at the same time.
No leaks anywhere.....shocks and Diff's need to be sealed properly! I would only fill diff's upto the "spider" shafts ...everytime you fill them. Always build your shocks the same way.....everytime!
Before you start talking and altering set-ups. Decide first....what are you after from the car? What is it you want it to do that it is not doing at that time?
And alter ONE thing at a time.........this is really hard to do ....I know!!
Now. If you want to run the 4mm chassis. The already stiff G4 construction is going to be mae even stiffer! You will need to come down on spring strength!
Actually, you need to alter the spring strength/ to oil ratio.
In other words keep the same oil and just go softer on springs. The stiffer you make a cars chassis the softer you will need the car's suspention to be.
Thats why it's hard to run a stiff chassis on a bumpy, low traction track!
I have specific set ups for different tracks and traction conditions. If you need them, just say what the track conditions are
Get your motor and the excelent clutch we have on the car working well, and you'll have a race winning car on any track surface
