Michell91

Mine weighs 6lb9onz dry with a Jen 56 and pipe in it the performance is stunning, how much does yours weigh? it must be very heavy if a 91 does not do it for you.

EDIT: just a thought what prop are you using, I have a 14.5x4 Graupner Cam prop specially designed for IC 3D, it may be you need a different prop to get the thrust needed for good performance on these things, I would have thought you would need something in the region of a wide blade 15x4 or maybe 16x4 at least.
