ST Giants
I recently broke in an ST-3000 with 64ozs (4 tanks) Wildcat 15%/18% oil. I ran another 16oz with Tower 15% cut with 50% Methonol ($2.00 per gallon) -- no problems.
I finally flew my H9 Cap with another 16ozs of Tower/Methonol and had great idle, hi end (7000+ with 18x10 prop), and excellant transition.
Tower 15% cut with 50% Methonol gives you a fuel that is 7.5% Nitro and 9% oil.
I've seen posts on here and RCONLINE that recommend 5% nitro with 5% oil. The Byron's ST fuel I purchased had 10% nitro and 10% oil.
