Actually when in flight the arms are very easy to lift as the weight of the center body is actually lowering and the arms are just holding the craft level. So really the weight of the body makes it very easy. Its actually harder to lower the arms as it must push the center body and frame up. Using the 360 degree servo with my other 3d printed Inspire clone on 6v does a very nice job with little effort.





I do have a question regarding the needle bearings. Do you think using a printed nylon split bearing in the outer arm joint would save some weight and allow for a tighter fit instead of the metal needle bearings? I noticed on the DJI Inspire they use a split collar with a stick on rubber shim to tighten arms enough to not allow any wobble.

Nylon or PTFE would work well I think. And I agree the bearings do increase the weight.  The actual movement is limited, it was the stren. gth of the bearings I was using. Only one way to find out :-)

Were you thinking of something like... http://www.bpfonline.co.uk/show_product.asp?id=15945&catid=11068

Yes something like this.


I have STL if you want. I cant post it due to size being over 2000kb, Im sure with your talent you can probably make a better one. Im new to this stuff.

thanks fella, never tried printing nylon. I will have a read to see if my print will manage it. :-)

Well, after I managed to fly mine into next doors conservatory (on purpose of course.. lol) It fell from about 5 meters up.. Broke both inner arms, an arm link and an outer top leg housing. I've been waiting on some pla to get it rebuilt which came today. So I've printed the outer legs but added a bit more strength to them and I will print the inner ones tomorrow.


Attached are a few pics of it stripped down a bit which might help you in the build process.


What I would advise is always have a spare set of inner joints / arm links and outer housings.. this way you can be back up in the air in no time, then reprint more spares.

Steve or anyone is it too much to ask you to explain how the movement of the arms work since i do not seem to understand. Thanks

I will try to explain it.
The 360 degree servo sits on top of frame and will spin a threaded rod that extends thru the frame and thru the 608 bearing mounted inside the frame. The threaded rod passes thru the arm lifter block, which has a nut attached to it. SO as the rod spins the block moves up and down. That block attaches to the arms via leg links. So as this block moves up/down so does the arms. They are stopped by the micro switches positioned at the upper and lower positions on the frame. Hope thats helps you.

Heres a video of my other Inspire Clone while I was building it. It shows the lifting mechanism which is based on same idea.

HI, I have two questions:

And has which position as it should be must put the tube 22mmOD in the outer leg housing?
I have end up printing pieces and I wait for some elements to make final assembly.

About the gear servomotor, do you know if I need a PPM encoder with my Turnigy TGY9X beca

Sorry that I do not know. I've got mine run with a Futaba 10c radio and frsky reciever. I am using a channel to control arduino and it works fine.
