I just got an Estes Hy Flier XL. Although the instructions don't mention it, someone that has one told me he had to add 14 grams of of nose weight to make the rocket stable. Has anyone else had to do that.
 
My Estes Hi Flier XL has a mass of 5.1oz w/o motor.

It has no additional nose weight and the model has been flown with D12 and E9 motors.
 
My Hi-Flier XL has flown fine with no additional nose weight.
You might be thinking of the small, BT-20 based Hi-Flier.
Fred Schector has reported the smaller one needs nose weight to be stable when using C engines.
 
Thanks for getting back to me. The first flight will be on a C11 just to be on the safe side.
 
I've got a High Flyer Xl and I've flown it over 25 times using estes motors, it's been a great rocket. Several times I've used a keychain camera attached to it and It's given us some great footage.
 
I had to add ballast to the front of mine, but then again I up-engined it for 29mm motors.
