XK K110 and 120, this is what I use when replacing head spindle

[@CloudyFlyerRowdyNiemira]

THESE ARE STILL MY FAVORITE AND THE BEST MICRO HELI OUT THERE ...LOL I HAVE 4

[@jigarpatel1978]

Hey I'm new to all this. Crashed it on maiden voyage years ago. Now picking it back up. I only have one of the black o-ring to put on one side but not the other. I also don't have the two washers. I do have the two nuts that go on either side. I have the stock version falcon k100. What do I do to repair it? Easily available to buy online or at an rc shop? What are these pieces even called? Glad I saw your video.

Go to motionrc.com they have spare parts for this heli www.motionrc.com/products/xk-k110-with-gyro-244mm-9-6-rotor-diameter-helicopter-ftr-wlt-k110b?variant=605770383385#hash-tab-3 I guess you are referring to the rubber ring and the metal part that goes on the heli head You have to have all the parts for the heli to fly it. If not it would create vibrations This heli is been discontinued, so, hard to get parts for it. If you are committed to learn grab some parts as they would not be available later on

I see there are no bearings used, did it use bearings from the factory or not?

[@helifan2346]

Factory Nothing change, just what I show in the video

[@Rockmixerstar]

@@helifan2346 Thanks, my XK K110s has bearings plus spacers and it looks like mine will be a close fit as the feathering shaft doesn't seem long enough. I am waiting on the bearing as I lost one when the screw came out of the shaft and I lost it and the spacer.

[@helifan2346]

@@Rockmixerstar And I just got rid of a lot of of spare parts and helis, k110. If not I would send them to you Make sure that you get the original spare parts as there is some cheap material used lately Good luck!

Where do I get the screwdrivers to fit the blade grip screws?? I found one that fits. Can I have the measurement? I take it you hold one end with one and unscrew the other one right? Thanks

[@helifan2346]

Yes, you need 2 screwdrivers, one to twist and the other to hold the other side screw The screwdriver is JIS size #0, I would recommend you one from moodys brand www.zoro.com/moody-tool-precision-screwdriver-tri-point-0-2-12-in-round-76-2334/i/G3290594/ Look up for JIS screwdrivers as they are not regular Phillips screwdrivers the one that this heli or any other rc toy uses

[@stevejohnston8543]

@@helifan2346 Thank you very much for the quick reply. Could I get those at a hardware store or the like or do they have to be ordered? Any advice on changing the boom? What you have to remove to pull the wires out, how you clip the zip tie etc. Appreciate it. I’ve got several on the shelf that only have a broken blade grip. I guess there is a screw at either end, they don’t come with the grips it seems. Thanks.

[@helifan2346]

@@stevejohnston8543 very careful when pulling the boom out, very gently try to pull it without twisting the boom as is very fragile and may break, just unplug from connector first and you may need to use some force and be aware as when it comes loose the wires may come off from heli body. Try to look how they run the wires so whenever you are ready to install it back to run it the same way or on one side of the heli and use hot glue to keep wires in place and away from main gear. You have a screw on both sides of the blade grip, yes, that’s why you need 2 screwdrivers I don’t think that you will find JIS .0 on the regular hardware store If you are replacing the tail motor or if the tail motor wires comes off, just twist around the boom from the outside and run it thru the main shaft and servos as before, don’t sweat to get it thru the boom as you have to cut off the stock plug and then re-solder. Just run it on the outside of boom and twist it, no fancy looking but works Forgot to mention, I guess there is a screw holding the boom in place. Unscrew the 2 top screws that are closer to back servos and check for it, take it apart so you have a better view

[@sauldelbarco6361]

Hi!, where do you buy the red o-rings that you use?. How well these o-rings work? Thanks for advance Regards!

[@helifan2346]

Saúl del Barco to be honest with you, they don’t work, at least not for me, they don’t take any slop out, they are loose. Forgot to remove them. They should work on other helis, but not on this one.

[@RealThirdy]

hi sir the rotor clips is made of plastic? i see metal upgrade i just want to make sure if the stock is plastic

[@helifan2346]

Ecoi Villesis yes, it's made out of plastic

[@RealThirdy]

thank you sir! im planning to buy this

[@sharkshoe369]

why do my propellers keep flying off while flying. please help.

[@helifan2346]

They come off while flying? The whole head comes apart? Or just the blades and you loose the set screws? If the head comes apart while flying, use 2 screw drivers on both ends of the head as I explain in this video. If is just the blades that means that you leave the screws too loose or the blade grips hole thread is gone, make sure that blades are not too lose or too tight as I show in the video, if you can make it too tight, the screw that holds the blade in place, that means that the thread still good. One way to know, take blade off the blade grips, use the screw on each blade, one screw at the time and check which blade grip is bad or it may be the screw Let me know your findings
