RE: Engine for 18lb plane
I have a DA50, Brison 3.2, RCIGN 62, Evolution 45, Evolution 58.. and now a Brillelli 54 (similar to the new 366GT, just smaller jug)....
If not going with a DA...
I would go with Ralph's G62... Less than $500 shipped... best bang for the buck..
or Brillelli 366GT... (going by reports on the internet)....
The 3w's at our field a running great, and seem to be stronger than most of the others in there class... (They are heavier, but are on sale at Aircraft International)....
