I now have the full set of Blade copters Having just obtained the daddy 4003D. I purchased this used with a boat load of spares.It has only flown once as a demo when purchased it is as new. But seller looks like he has had a play with settings on tranny, linkages etc.So if any one is familar with this helicopter and can spare an 1 hour checking it over it would be appreciated.Im in the Leeds area. vinny
