So I had it wrong too, it was raised to 80cc.
Ok no problem, but these are the ROAR rules. IFMAR don't have the class, so no rules and the EFRA rules is:
1/10 th I.C. Track cars
5.3 Fuel Tank
The fuel tank incl. filter and fuel pipes up to the carburettor may hold a maximum of 75 ccm. No loose inserts allowed
If you are a good engine tuner then it does'nt matter if it is a big or a small tank, but if you are a bad or not so good engine tuner, then it is better with a big tank.
You are right, I am right depend in which part of the world so let go racing.
Have a nice weekend
