RE: Cox TD 09 Fuel
SIG make a 15% nitro with 20% pure castor oil blend that will work fine. Like most steel cylinder/piston 2C engines, they really like 100% pure first press castor oil as there lubricant in a ratio of 20-25% of volume, and nitromethane of between 10-35% per volume, the rest is pure methanol.
I mix my own....
My standard summer mix is 20% nitro, 25% castor, and 55% methanol.

I run Sig Champion 10% nitro, 20% oil 50/50 castor/synthetic. Couple thousand flights on Shark 15, Jr. Flitestreak, etc. I have run higher nitro fuel but I find the 10% to run fine. Run a Cox 7 x 3.5 or APC 7 x 3 and turn loose at around 15,000.
