hello from France,

My 12Tr T-spec 2004 run now 10 liters of 16% nitro fuel (EFRA specs).
There's no differences between my engine and the JP or Rody's...
We run only on very large permanent tracks.All italians brand refuel at 5mn and I at 6mn and the t° is lower....

I just change the rod after 2 liters and the engne is like new.

The new machined piston is so good.

Enjoy it
