someone has told me I neede a little reflex in the elevens on my too. Can anyone advise how much is needed?

I think it's 2 or 3 MM.

Yep.....

Original wood or composite? The composite one balanced correctly needed 1/16”

All the Kangaroos from day one have a airfoil with reflex on it.. so if your cg is in the sweet spot and you fly it at full throttle most of the time there is no need of added reflex . However as the instructions and common sense points for a conservative CG as well initial moderate speeds, anything around 2mm up is ok.

Voodoodb,

Thats about right on the reflex, I also sent Vernon some pic's of the speedbrake and C.G. info.. You'll have fun with the Roo !! See you next year at Afterburner !!
