Hi Albert,

What we need to confirm is if the listed CG point is truly accurate. A couple of ideas here - is it on the spar or not? Does it call for a point that is 30% from the leading edge.... more or less than that? Run a search for the Tiger plane and see what others have done. I'm assuming you mounted the battery and receiver as far foreward as possible. Why don't you give Goldberg a call? Often we go through what you are going through only to find that it will fly like a noseheavy dog and then need to move the CG way back...!
