I'm not sure who made the plans yet, they're being sent to me and should be here in about a week. Should I be hoping for RCM plans?

I think I should be okay with the weight of the engines, I like the idea of the simplicity of the gas engine. And I think multiples of any engine will sound good. And a little more power will be a good thing as long as the prop will be fitting. Isn't there a saying somewhere that you can never have too much power?
