newbtoRC, Not sure what 4* you have but I have the 4*60 with a Mag 91 4c
with the APC 14X4W prop and my 4* hovered very good with pretty good
pullout, She K.E. pretty good also once I mixed the pull to the belly out...
My 4* was all stock except for C/F pushrods and large arms also on the tail
heavy side... But she stays home a lot now... Having a lot more fun, and all
is a lot eaiser to do with my UCD 46/YS63... It's a blast...
