I have a Shuttler F-15 70mm ducted fan. Span is 1100mm, Wingspan 740mm. Flying weight 690g. Anyone have any idea where I would balance the plane at. I've look closely at the manual and it does not say. All is says is "if the plane flies like a wave after takeoff then the nose it too light Or, if the plane rises slowly or flies parallelly after it takes offs, it indicates that the nose is too heavy" Heck of way to adjust the CG. I like that word PARALLELLY . Any help would be appreciated.

The Shuttler F-15 is a few years old but the recommended CG seems to be here in the image below on the red lines...about 225mm measured from the back of the main wing. The red arrow in the back shows where to add the weight, if needed. Note the long wire on the left wing for the 72MHz receiver.

Good luck!
