Hay guys, this is my second post, I am about to start a 60" funaero albatros II build up but i wanted to ask a few things on engine choice. I Looked over the build up of the Albatros III post that was done that has the 65" wing span. My plans call for a 91 4stroke and the shop near me carrys the OS type engines or should i have him order the saito. I do have a supertigre g90 in the box that was to be used on a p40 that i have yet to build but i do not think its a 4 stroke. Which make do you think? I know some just have personal likes and dislikes, but do they differ. If you like neither which one and why. Please be aware (if you suggest another engine) of the nose cowl of the albatros, so space and cooling is a concern. Thank you for any help guys.
