i have been testing oils and oil percentages in my fuel.
i use jp's and run 16% nitro.
the questions are.
1- what oils cool.. the castor or the synthetic?..i use both in my blend..
2- using more synthetic as to castor gives me more acceleration..why is this?
3- when using 8% oil as to 10% oil, the motor revs harder but hotter.
4- i added 1 x .1 head shim (now using 2) and the motor cooled down by 20 deg.. why is this?
5 - i want the best run time, the best performance and most importantly.. i want my motors to last..
i do realise that i might be pushing sh#t up hill. i see the top runners always replacing rods after the quilifys.. i cannot afford to do this, but i still want to keep up with them...
any suggestions would be greatley appretiated.
