Ahhh, the first bearing Fox Combat Special. Two needle bearings on the crank. 1961?  Can break the crank. There have been comments about that issue on SH recently.  Would look great on any period combat plane.  I think mine was on a Giant Killer.   TS

Not being a combat guy, thinking it would fit the Umland Super Combat Streak.

The pressure fitting in the rear; how does that work?

Beautiful example of Duke's first needle bearing Combat Special. That engine also introduced the square intake that Duke stayed with for the duration of his combat engine involvement.  "Front loader" was my nickname for these when they would come in for repair back when I was at Fox. We didn't have any more .35 cranks to repair with (if crash damaged/etc), so I would fit them with a 36X crank and the result was a "stroker" engine.

As for breaking the crank: Not a problem if you don't go crazy with the nitro. The engine SHOULD outlast you.  %^@  For sport flying and the general health and longevity of it, I would suggest 10% nitro and only castor oil.

Attached is an engine review by Peter Chinn from back in the day.

Enjoy!

I  agree with Andre. Back then we were 'pumped up' on the nitro..... and, they broke. I think us kids wanted to be like LS! I would be confident running Sig or Powermaster 10/22. Combat Streak would be a great ride!  TS
