I just ordered the Goldberg Super Chipmunk. Came here to check on an engine for it. Seems like it will fly on anything from an O.S. 46 to a .120 4 stroke. Big difference. If I was into unlimited verticals, I'd buy me a rocket!

Anyhow, I'm an average flyer but I want my chipmunk to have enough power to get it off the grassy runway easily and fly more scale once airborne. I can always throttle back. I love the sound of the 4-strokes but on the other hand I have a new Super Tigre .61 2 stroke new in the box. I wonder if I should order an O.S. .91 4-stroke or go with the .61 super tigre?

And also, does that chipmunk have any nose over problems while taking off or landing with the wing mounted gear? Just wondering.

Any advise would be highly appreciated.
