Post by: Ronald Eshleman on April 20, 2015, 01:11:58 PM

What fuel mix should I use in a Fox 40 I just purchased on Ebay?

I know there are a lot of guys who will disagree but I have had a great deal of success using Brodaks 10/23 in my Fox 40.  I bought it new from Fox about four years ago and mounted it in my scratch built Big Tiger, a Claus Miklas design and I have absolutely no regrets.  It's the only plane I've ever had it in and the performance has been wonderful.  When I first ran it I was using the Brodak 10/29 for probably the first 36 flights or so then I changed to use the 10/23 because I wanted to reduce the oil residue on the plane and cooked on the head.  Again, I've been very pleased with the Brodak fuel.

What type Fox .40? Not that it really matters as I would probably suggest the same for older or late model.

Powermaster GMA 10/22 or 5/22.

Works beautifully.
