How to replace a Blade CX2 inner shaft
Fortunately, E-Flite Helicopters are easy to work on and the inner shaft isn't too difficult to replace. I was able to take care of mine in about 20 minutes start to finish. Read on for a picture tutorial showing how to do it.
(Notice the hub has broken off the inner shaft on my CX2. It needs to be replaced)
Start by removing the full canopy. If you haven't done this before, just pull off the rubber stoppers from the plastic rods and then slide both the rods out. After the rods are out you must remove the landing skids. All that's required is to pull them out of their sockets. They are only pressure-fit.
(Front canopy removed)
Take out a very small phillips screwdriver and loosen the two screws on the bottom gear.
(Loosening screws on bottom gear, doesn't look like much of a helicopter now)
Now grab a hold of the upper hub assembly and pull. It should slide out without too much resistance and the gear will just fall off the bottom.
(Just pull!)
Insert the new inner shaft and line up the screws attached to the bottom gear with the flat parts of the shaft. With the shaft pushed all the way in and the screws lined up, tighten the screws until they are fairly tight, just a little over thumb-tight.
Unscrew the flybar retention screw and remove your old flybar (if it's still straight). It should just pop out. Installation is opposite of removal so just pop the flybar into the new hub, clip the linkage on and put the new screw in to thumb-tight.
The new hub will also need rotor blades. To transfer your old rotors, just unscrew the screw on each side to remove them and they should slide away from each other to separate. Slide them together on the new hub and screw in until tight. There can't be gaps between them or the helicopter may wobble.
Put your canopy back on, re-insert the landing skids and you should be ready to fly!

Hi i saw2 your tutorial on replacing shaft and stuff on blade cx 2
I have a question, does the top blade motor, run hotter than the other, like mine is doing ?
John
I think it might. I installed the heat sink on mine to get a little more life out of the motors but it would make sense that the top one which spins the flybar uses more power and puts out more heat. It has to work harder.
can you just replace the top of the shaft. Because i bent the blue thing
Hi. I saw this post after looking at how to change the main gear (lower of the two). I am having trouble loosening the screws on the bottom of the shaft. Any tips?
Thanks.
Thanks for the DIY instructions and the guide to R/C Helis. I just bought a Blade CX2 and trying to get a hang of it, and your DIY guide helped me change the rotor blades.
I am trying to replace the plastic lower rotor head and can't seem to figure out how to get it off the shaft ??
Hi,
Great article, thanks. I'm having the same problem as Larry Edgar: want to replace the lower rotor head and not sure how to get it off the shaft. Any ideas?
Many thanks,
Steve
I was able to replace the lower rotor head, but now I'm having trim issues. I can't prevent it from forward and to the left travel
