ENGINE HELP NEEDED
 

I just got back into on road racing and purchased a REX RE12S3 Engine. They have a special page devoted to fuel and break in. Is says to use 5% nitro for break in and then use 10 - 25% nitro after break in. Anybody have any suggestions as to what to do? I am having problems finding 5% nitro fuel. How many tanks for break in? What should the head temp read? Thanks

Hi, The only real reason that they r saying to use 5% nitro is because 5 % gets the engine MUch hotter then say 10 - 30 % will .So naturally 5% will get ur engine hotter for proper heat cycling. u dont necessarily need to do u can just go and grab some 10% and it should do the trik . Hope this helps mate , Harawong:D

Just run the fuel you are going to race/drive normally with.
