....which recommendation are you referring to ? Todays recommendation for the 2300 for instance is:
http://www3.towerhobbies.com/cgi-bin...FV80&P=SM#tech
REQUIRES: Propeller: 16x8, 18x8, 18x10
Glow Fuel: Minimum of 18% high quality oil by volume in fuel,
Nitro content should be between 5-15%.
SUPERTIGRE Recommends Fuel with 18% oil MINIMUM.
The plane is a Joe Bridi Big Dirty Birdy. It was an early 2 meter pattern plane. They are rare now, possibly obsolete. I have a new header and long pipe for it now.
