The reason I ask is that I may be moving to the UK, and will bring my small nitro planes with me. I don't want to spend $70 a gallon for 25% nitro glow fuel. I do want to keep the response and power "crisp" though. Is there any way to increase the compression ratio?
I'd love to convert all the way to gas, but it just isn't feasible for me right now.

I'm fairly certain that the power gain with nitro and reduced compression is greater than with low or no nitro and increased compression. The problem is that nitro broadens the acceptable needle setting, while no nitro fuel makes needle adjustments more critical. Just what the instant gratification crowd does not need. Still, it would be nice if they offered a few of their engines with the old high compression ratios.
Hobbsy pointed out a while back that his modern Saitos run just fine on 5% nitro, just not as crisp. If I was worrying a bunch about crisp, like for 3D flying, I too would be using high nitro fuel. So he may have a point that this is not really a problem.
