I recently aquired a Fox 35 Red Head.... I personally have never heard of them.. what is the Red Head designation? is it a speed or combat or stunt engine?

New Info... i just looked at it again.. is a Rocket....

It was a "Sport" version of a Combat Special. Basically a two-stroke (only) engine, unlike a Fox 35 Stunt. It was much worse about vibration than any other Fox, other than the Combat Special it was derived from. But that didn't deter anyone. They were $10.95, according to the lore I was taught, when the Fox Stunt had just gone up a dollar from $14.95.

Yep It is a ROCKET, I have 2 new ones here in my FOX collection. It was a low price sport/ combat version from the Black head 35
FOX made a lot of 35s y1
from the FOX history web site
1958
In 1958 Duke Fox figured a way to get more power from the combat special. He improved the intake port timing, he improved the piston and baffle, and he painted the cylinder head black so that you could tell the difference from the first combat special since they both look the same except for the above mentioned changes. Also, in 1958 Fox introduced the new .29X Racing Engine. It looks just like the black head .35 except it has a new style cylinder head with machined fins and is aluminum color. This engine has only "Fox" and a circle on the bypass and has a bore of .738.
1959
In 1959 Duke Fox introduced a "low price series" of engines and called these engines "Rockets". The first model Fox .35 "Rocket" had a red head and the name "Rocket" and a rocket design on the bypass. The intake venturi was made smaller than the previous combat engines and it did not have a removable insert. Aside from these minor changes, it looks like the first and second Combat Specials.

Had one on a Debolt Jenny RC plane----looooong ago.
With the best throttle available at that time, it was a two speed engine: full blast and stop!! ::)

Jim, your mention of the DeBolt Jenny sure brings back memories. In the early 70s I built one, in which I put a Heathkit 4 channel system that I built. It was a big airplane, and it seems like I had a Merco 61 in it. I had no instructor, so I made several very successful take-offs................Glen

Glen,
I still have a DeBolt Patternmaster kit-------don't know why, but I do.
Got lots of rc stuff I need to dispose of.
