I'm sorry I commented. I've run dozens of Fox engines in the 70s only because they had the lowest sticker price in it's day. They were mostly dogs. I never ran a .50, didn't want to. I had enough. They are heavy, ugly, convoluted to tune, and why have unpleasant experiences in the hobby more than necessary? I switched. Thanks. The Castor content is a proven practice among competent fuel mixers of vintage engines abroad, not favorable to the keyboard experts that never tried? Thanks for your edit, but 28% works.
Finally, a .35 C/L or a .50, or any other displacement, WILL have heat problems with Cool Power in a vintage application, if it doesn't just sieze up first. Heat in a two stroke could be other things, but from cyber space, the comment on fuel used stood out to many as a problem, and it is. Correcting that first allows one problem to be resolved so further test and troubleshooting can be done. At least it's not stalling.
I've owned and have run hundreds of engines. Most I've kept over 30 years, and I eliminated every Fox I've ever bought, with a smile. Today people will spent $60 on a OS LA .40 engine, with cheap features as a bushing crank, plastic remote needle valve, and fly something even slower than a Fox. So from that perspective, yes, the Fox has power. But some of us fly SX .50s, Super Tigre .51s, and even Magnum .52 engines and never come second to a Fox .50. In fact, they are a lap ahead. Aside from smaller displacements, Fox hasn't even been in Towers stock, because it's crapola.
You are wrong about the 28% oil, most of my iron piston engines run fine on 20% oil and will tolerate a 50/50 mix of castor and synthetic. The C/L stunters are running the OS LA control line engines on 25% oil because the extra oil helps give it a good 2-4-2 break. My Enya and .15 Fox do not need such high percentage of oil. The Fox stunt was made for that high oil percentage to the point of not having enough cooling fins for lower percentages. That was such a good engine for its application that OS cloned it and it is still a favorate with C/L people today, though mostly with ABC cylinders and hemi heads hop ups.

You have never run a Fox in your life! Or else you would know they are always light, some are slow, but most are powerful for their size. If you had actually hit on their faults I would believe you, instead you insulted their very virtues, and missed their faults entirely.
