What is a good fuel to use in LA 40 and Brodak 40

I have had good luck with Powermaster 10/22 1/2 castor, or SIG 10% 1/2 castor
They both run well on either...

Sig Champion 1/2-1/2 castor/synthetic, nitro 5-15% per your engine, plane, altutude conditions.
I use the 15% nitro as I fly at 5K' altitude but 10% is acceptable, if thats all I can get at the time of purchase.
Also I also boost castor up 2-4% if engines are not behaving  like they normally do.
Powermaster is good stuff, if you can get 1/2-1/2 castor/synthetic blend locally.
!0% nitro should be right at your location but if you go to a flying site a more than a couple thousand ft. altitude, bring 15% nitro also.

Hobby store here sells power master but has synthetic in it.  That ok or should you use castor.  They also have Sig not sure what is in that

You just want a 10% nitro, 20% or 22% castor synthetic blend.  Both Powermaster and Sig are good, and available most commonly in those blends.  Both have the mixture on the labels.

Hey Bill,
Did you ever put that double Star 40 in a airplane yet? You know the one I sold you.
