Default Ducted Fan fuel??

I'm getting into the ducted fan scene and need help with fuel questions. I have a BVM aggressor with bvm motor. They recommend Wildcat jet A which I cannot get locally. I wonder if anyone has good experience using other brands and what oil addition (still castor?) that they add to get the magic 23% content for ducted fan motors. I can get access to Magnum, Sig fuels. Thanks.

I have used normal 15% nitro with 1 oz per gallon of turbine oil added. This was recommended by Larry Wolfe of Jet Hangar Hobbies. The logic being that turbine oil do not evaporate at the glow engine temperatures.
I know other people have used 30% nitro helicopter, which is close to 23% oil.

Good luck,
Edgar

What Edger said ! A little turbine oil works just fine. On inspection my d.f engines have vary little carbon in the combustion area and the bearings are lasting longer it seems. I noted a 200 rpm gain and a drop of 50 *F vs a ducted fan fuel. I'm about to test run this on on some sport motors too.

Thanks,
It seems that the concensus is to add a popular turbine oil lube, 1 oz per gallon to 23% blend oil mix using 5-10% nitro and the key being to keep motor on rich side, leaving a little trail of smoke. Fuel brand seems less critical, as guys are using Wildcat, Sig or even Powermaster without wiping out the motors as long as they avoid a lean run. I found a couple sites to try out that BP 2380 turbine oil they raved about.
