Guys i have an ASP 40 in my worldstar 40 ... with fuel is there any reason to choose a nitro mix over a 4 to 1 castor/methanol mix ???? The motor is one of the "beefiest" .40's at the range and i was wondering if there was any need to run nitro ???????

I realise that castor is a little harder to clean off the model once the days done. Is there anything other than that ???????
