So, what about these Kyosho Hype Cool Fire engines?
They look great in their red paint. I like the shape of the head, reminds me of old dirt bike motors.
I stumbled across one of these while searching for something else. It piqued my interest and so I searched for more information on Google and I could not find anything except ones for sale on ebay, in Germany.

I did see that Kyosho are suppling many of their planes with engines and servos fitted and ready to rumble.
Know doubt these are the engines?
Knowing the manufacturer, I'm sure they'll perform absolutely perfectly.

Looks like a GMS block.

-----------------
The area where the exhaust bolts pass through looks a bit like GMS. But after looking at the webbing alongside the front of the crankshaft, I'm not sure. I don't have one nearby to compare it to.
My McCoy engines ran great, once I didn't ruin them during break-in by running them too lean. No, they don't last very long, but I used to get quite a few control line flights out of them. Never actually wore one out, usually sold it on the model or gave it to a kid wanting to start out in modeling, along with lessons on how to hand start it.
I had a McCoy .29 R/C engine (Bluehead) for a while, but never got around to flying it. I did fly the dickens out of a friend's McCoy .19 R/C (Bluehead) on a Sterling Fokker DVII that he built. Beautiful job. First and only control line model that I flew with a spring loaded throttle control with a third line. It was a bear to hand start. But it ran fine otherwise.

ORIGINAL: More HP
What's all the hype about? Sorry... had too!

I would venture a guess, that "Hype" in their eyes has nothing to do with our definition of hype:
Main Entry: 3hype
Function: transitive verb
Inflected Form(s): hyped; hyp·ing
Etymology: origin unknown
1 : PUT ON, DECEIVE
2 : to promote or publicize extravagantly <hyping this fall's TV lineup>
But rather may have been a short synonym for "hyper performance" or something like that.

If you disregard the red paint and focus on the shapes of the parts it is a very cool looking engine. There's definitely a Retro thing going on. Much, much better looking than Evolutions and the latest O.S.'s that seem to have been influenced by video games. They remind me more of Hotrods than alien spaceships.

I think the carb is a strange thing on this engine. The barrel is held in only by a rubber o-ring. I also cannot remove the carb, it is in so tight. I have tried heating the crankcase around it. I will just keep working at it.
I got the rest of the engine disassembled. I wanted to check it out. It actually is really well made. There was no swarf inside, and all the machining looks excellent. It is a true ABC engine. The conrod has nice oil holes drilled in it. Schnuerle ports.

The head is shaped perfectly for high Nitro fuel. She’ll probably really howl on 20-30%. Usually with a head shaped like that, the timing will be a bit advanced. I’d not prop it real heavy if it were mine. I’d measure the timing though, but only because I’m a nerd like that.

Trumpet/funnel shaped heads and narrow squish bands are designed for high Nitro use. Bowl shaped heads with wider squish bands work better with lower Nitro fuels.

I am a fan of the Webra Dyna Mix carb, it is perfect for the Webra .91,that may be the reason the Hype .91 is wearing one. Contrary to popular lore it works well with just muffler pressure.

I got the carb body out today. It is the toughest carb removal I have ever encountered.
It has a liner pressed into the crankcase, some sort of plastic material. The carb throat is pressed into that. I almost believe they must have used a press to push it in during assembly at the factory. I heated the case and it would not help. Now I understand why, because of the liner. Well, maybe it helped a tiny bit. I have strong hands, and it took all I had to work it back and forth while tugging it upward. It took a long time but eventually I got it. Whew!
