So, what about these Kyosho Hype Cool Fire engines?

LOL!
I measured the carb throat and the insert bore in the crankcase. The carb throat was 0.550" and the insert bore is 0.510", a .040" tolerance fit!
No wonder it was such a bear to remove! I am convinced they had to use a press to insert it at the factory.
I machined the throat down so it is now a slip fit.

Before the EU was formed it was a hit or miss thing. I paid attention to this topic as I used to live over there. One country got it dirt cheap, and then one country paid exorbitant taxes, and then another couldn't even get it. I think Ireland was the country that didn't tax nitro, but don't trust my memory on this. We don't seem to have as many European fliers on the Internet now. The European Union thing probably unified nitro costs. We should ask Jaka the next time he posts something.

They are re-styled MDS engines, as were the RMX line sold by RipMax in the UK.
The carb shown is almost certainly non EOM supplied. It is a Webra slide carb. Probably why it was so hard to remeove. It's neck was not the correct 'drop in' size to fit in place of the original MDS carb.
