Hi, I have a nice OS46fx in my Spitfire and was wondering if there is a dummies guide out there for engines. I know the bigger the number the larger the engine..right?

A OS .60 is larger than a .46 etc?

What besides OS are good. I have 2 trainers that need engines in them and I dont want to go all out for them. My CAP 232 40 series needs an engine too and was wondering what you guys suggest? Budget is an issue also here.

Your thoughts are welcome and appreciated gents. :stupid:
