Replacing Rotor Blades on a Eflite Blade CX

I got an Efite Blade CX2 micro helicopter for Christmas this year and naturally I have gone through a few replacement parts so far, so I decided to start making Instructables on fixing the darn thing. I did this as a slide show as it is pretty much self explanatory. All you need for this repair is a new blade, in this case two, make sure you have the correct blade as the blades for the top and bottom rotors are different. You well also need a mini Phillips screwdriver, they give you one with the helicopter in the kit. I am changing the bottom blades in this case but the process is identical for the upper blades.

    I've gone through about a dozen blades. There are a few things you should know - First off, there have been a few different runs of blades and if you replace just one and the head is vibrating hard, you may want to replace the opposite blade as well. I had a few different packs of blades that seemed to vary a little in pitch and weight, even though they were all from E-Flite and all for the CX.

    CX, CX2 and CX3 all use the same replacement method. There are more details and photos here -

    Nice! I wish I had a remote control airplane thing, those are so cool. Haven't had one of those in years.

    Actually the CX2 which is the one I have comes with the aluminum upper shaft, but I well eventually get the aluminum swash plate and lower blade mounting hardware as well. I have the indestructible landing skids and carbon fiber tail boom from boom town hobby as well and those are great upgrades too. So far in the 6 or 8 times that I have flown it I have killed two sets of lower blades, the stock skids and the main gear for the upper shaft. I also want to try and make a custom canopy for it as well. As for helping you fly it I can't help you much there, lots of practice, I have been flying RC planes for about 5 years and this thing is a challenge for me. I want to get a Esky honey bee king 2 next but I think I well have to really get good at this one first.

    This would have been useful about six months ago...I had to figure it out myself. I highly recommend getting the aluminum shaft--it was the second bit to snap off on mine.

    Are you going to help me fly the darned thing next?
