PAW 55BR prop tests

Testing my PAW 55BR (.03) with different prop loads. Fuel is home-brew: 1/3, 1/3, 1/3 plus 2% IPN. I've had the engine for a few years, done considerable bench running. I'm looking for a suitable C/L model and thinking about a SIG 'Mini Zilch' or a Baby Ringmaster.

Interesting video, good to see the diferences, thanks

Great video - quick question - Does "IPN" stands for Isopropyl Nitrate or something like that ? Have you tried to use Amsoil Cetane Booster instead ? Last question - is there any other outlet to get Ether besides John Deer's premium Ether starting fluid ?
I will appreciate your feedback. Thank you.

Charles Bovalis, You are correct about the IPN. Cetane booster should work, about 2%. Currently I know of no other source for quality ether, unless you know some F2C fliers. Otherwise buy fuel from Dr. Diesel or Aerodyne. Davis fuel has propietary mix ratios so I avoid it. I like to know what im running
