Shane/Bart,
As I have said before, the Tucano flies OK with the C of G at the factory setting, but is a completely different plane with the 12 OZ of weight in the nose. I have over 200 flights with Tucanos and have maidened quite a few including mine where the C of G was set as directed and it flew as if it were tail heavy. 12 to 16 ounces transformed it into a completely different bird.
Watch my videos (and keep in mind that they were made with a less powerful engine than I have now) and if your Tucano flies like mine...well...you did not balance your plane correctly and have it set forward like it needs to be...not where the book said it should be.
Cheers,
Beave

Why Jan??
My Tucano has had heaps of flights and is perfectly balanced, rotation is a non event and landings are just sweet, why would you want to move away from factory specs is it works!!! If you are so convinced that YOU need the 12 oz then do the cg as per factory then stick the 12 oz on and then do your maiden flight .
