Remove the body shell ( it slides off after removing the front and pulling off the landing skids the inner shaft is quite easy to remove
loosten the 2 small phillps head screws on the gear collar and pull the inner shaft out from the top use a good 00 size phillips screw driver
like a WiHa (german good tip most hobby shops carry them) to avoid bugging the screw heads I think the size is either 2 or 2.5mm
I plan on replacing them with hex head allen screws there will be an aluminum head upgrade for this quite shortly. One stunt is to wrap
thread around the piece that goes over the shaft and use a few drops of CA on it this makes it a little less likely to break BE CAREFUL do not get any CA in the flybar pivot or anywheres else martin
