Title: Fuel for Cox engines: .010 TD, .020 Pee Wee, .049s.
Post by: Bill Little on June 05, 2007, 09:43:03 AM

Hi Guys,

I have a gallon of Coopers 20% nitro fuel.  It's great fuel, but it is around 20% all synthetic oil.  I have plenty of Bakers Castor Oil from Sig.

What I need help on is I want to "mix some" of this for my Cox engines.

Please give me a good ratio for mixing a quart of this to use in these engines until I can actually get some 1/2 A fuel.  (which could be some time from now!)

TIA!

Hi Bill and all!
The only time I fried an engine was flying a 049 TD with all synthetic fuel.
Always had better success with castor in Coxes.
It´s my own experience.......
Regards from Spain.

Just an FYI.  TD 09's and 15's run fine on Sig Champion 10% nitro 20% 50-50 oil.  I think the smaller engines will need more nitro to be real happy.

Hi Ty,

I *thought* I found a Kart Shop about 30 miles from here that I could get nitro from, but no...........  I even asked a buddy of mine who runs a 600+ cubic inch Pro Stock, and I haven't heard back...........The circle track guys don't run nitro and all the locals seem to have gone to nitrous oxide for speed.  No one around here running a Funny Car. :D
