Got an Ultrastick 40 from my sweetie for Xmas and am gettin it ready to fly after I warm up on my Avistar but I am perplexed by the nose heavy set up I have it looks like I will have to do surgery on it to put the battery back far enough to get a good CG. has anybody had this problem? And does naybody have some suggestions on how to fix it without surgery?I am using a ST gs45 engine on it.

easysport:

Do a search on "Ultrastick." There was a very active thread on this plane, telling the weak points to address.

Replace the aluminum ingot of an engine mount with a fiberglass mount, and tuck the engine as close to the firewall as you comfortably can.This got mine much closer to the desired CG.Then again, I don't know if your engine is heavier. I still had to add an ounce to the tail to get to the aft side of the specified range.

Good luck

Thanks for the info JJ and Avistars also float upside down very well too and don't ask either

A similar question that I answered, Look for my posts and pictures to help you out, adding weight is the last thing you want to do. Good luck
