I have A 66" extra 300S and it flies great except when I do a knife edge it wants to
go toward the belly....do I need to adjust something other than the pilot!?
Also Its just a bit on the balancing of being tail heavy (lightly).
2 others flew it and one says add weight to the tail & the other said add nose weight?
I am Stuck?

it has a 90 2 stroke and weights in arount 8.5 to 9 pounds.
Here is a pic of the model..

Thanks
