Hah! Bruce. Ya grab me dude! LOL

The article in RCM is exaxctly tyhe one brought to attention by the cropped page from RCM.

Nope you are 100% RIGHT ON. This thing is S-L-O-W ! .049 I don't care which one you have -- it's still a small engine

This was RCM 7/81

I'm still bangin' out FULL SIZE PLANS with that old ENCAD PRINTER that I bought back about 2002 -- or so

Specs on it call for 18 oz. Mine came in at 22.25oz ?? !!

Off topic a little.

Q) How can different .049 engines be more or less powerful. Is it not all the same displacement?
