I have a Fox 36X that I bought at a swap meet.I'd like to use it on a Super Satan once it is finished.I need some info on fuel. Should I run all castor or 50/50? I'm thinking 10-15% nitro. This will be an ocassional flyer, I'll use the Pyschos for tearing up the sky. I do have one other question; When using these new engines( os .25 Tt 36) for combat, are you setting them up for a solid 2 stroke or do you keep the 2/4 break. My OS35 fp launches rich, after 10 laps or so it goes somewhat lean and runs the tank out that way. I'm using a plasic tank with hardlines(no clunk). Doesn't give the REAL lean laps at the end, just quits.Am I correct in thinking a solid 2 stroke run needs a higher oil %? My current fuel is Byron 10% w/ 20% oil(traditional mix?). I'm considering some Brodak fuel( higher oil %) or might wait and see what is available at the Nats
Thanks.

I will let the experts chime in on this. I myself just try to run the old engines a little richer than normal. I am putting a Super Tigre .35 on my Equalizer. H^^

I only tell you what we did in the 60s and 70s with these engines. Back then, we used castor of at least 25% content with much higher nitro content than you plan to use. They ran well on the hottest days and I never seized one up. The 36x, as you know, has ball bearings and I never had to replace them.
Fast forward 2008- I flew my Larry Scarinzi hopped up 36xBB on my Sneeker for the first time since 1976. Yes, it required some afterun oil to free it up from the dried varnish, but the engine ran great on a pacifier. After two flights, I decided to let my engine guy look it over.
After cleaning the interior varnish, he was amazed at the condition of the internals. No rust or wear and great compression. All due, nodoubt, to castor.
It's messy, smelly and not popular at any level (R/C or U/C) except with some Ukie flyers who swear it gives the the best protection.

Hey Doc
Which Super Tigre .35 are you using on the Equalizer...........the lighter .35C or the heavier, but meaner G-21 .35? Although I have two G-21 and used them in competition, I found that the .35C was a pretty good engine. At present, I have four .35C Tigres and tend to use them more for sport flying the old combat designs of the 1960's and 70's because I am getting too old and slow to keep up with the G-21's any more. I've never tried that thing of legend, a Nelson .36!!!!!!!!!........TDurrill #^ H^^

Found the C-35 was thirstyer than the 21/35 in a stunter, Same for Combat ?
-
Terrence I think it is the old 35C. Used it on tank pressure back in the day. Now have an insert to run on suction. H^^
-
even the infernal Stalker engines are recomending 22 % , Syn. with 5 % or 1/2 castor . to taste.
Ya dina go lean on the Castor if theres heat about .

Was working on the plane last night and looked at the Tigre. My mistake as it is a G21-35. jeh H^^
-
Doc, speaking from experience, that old G-21 .35 Tigre will be plenty of power for that Equalizer. You are going to get some really hair raising flights with the right tank, fuel and prop..........TDurrill #^ #^ H^^

Meant the ST .21/35 ! just a leg pull, though . allways thought a 21/29 RV on a 11 x 4 d do it !
Digressing further (a 21/40s NOT a fox 36 ) wottle it do with the 9mm intake in something like a demon,
a ST 40 BB ? (got two ) .
