Micro Newbie Questions About A Micro Heli

Hello everyone,

I'm new to the hobby and a new owner of an XK K100. As suggested I proceded to take it apart first to check all the components and screws. Unfortunately I accidentally opened up one of the servo's and was unable to get it back to a working state. I have ordered a new servo, but in the repair process also removed one of the servo arms of a working servo.

I have tried to center the servo by finding both ends of the range and made sure the middle of the range became the 90 position of the servo arm. Is that enough or should I use an actual servo tester for this. (It's ordered and on the way)

Also, do I need to check the pitch of the blades and perform a blade tracking procedure on this micro heli?

Thanks in advance for any advice.

Cheers,
Vincent

All you need to do, since that helicopter was setup from the factory, is level out the swash. You can do that with a simple zip tie, and I will post an old video of mine from years ago where I show how to do it. You can also do it off of the blade grip if you don't want to tear the head apart. But a zip tie is way more precise than a swash leveler IMO. And, best of all, it's free.

As for blade tracking, when you get it up into a hover, just get it to eye level and have a quick look. If it's tracking pretty close and you don't see any vibration, you should be good. If you do notice some off tracking, put a dot or red and a dot of blue nail polish on the tip of the blades. Make sure you try to use the same amount and in the exact same location so you don't throw off the balance of the head.

So the XK K100 story continues....

Although I have ordered a new servo I wasn't ready to give up on the old one and today I decided to give another try getting it working again. I had a clear head al lo and behold, I did get it put together again and it seemed to work ok.
So I proceeded to set the servo's to neutral, made sure the arms were attached closest to 90 as I could and attached the servo links to the swash plate.
Next, I was going to take off the head to make sure the swashplate was level using the procedure tony suggested in the previous reply. But darn....the screw that the head was attached to the shaft with broke off.
I have never drilled out a screw and am afraid to try it on such a small screw. So I have now also ordered a new shaft, a new head and a set of screws. I also added a set of linkages because I'm sure I'll break some of them also. This is getting to be an expensive little bird.
For now, the head is fixed so I went along trying the swashplate leveling method with the head attached, but suddenly the "fixed" servo went crazy. I do not trust it so I guess I'll have to wait some more for the new one.

Smaller, micro sized helis are more expensive than people expect. They will nickle and dime you to death.

Just like my wife does LMAO

Those XK helis are awesome little helis. I’ve got two K110’s and two K120’s. I’ve beaten the snot out of them. I’ve been able to do back flips with them giving negative pitch and no negative pitch to them when upside down. They do just about everything a full sized heli does. The only thing I’ve seen is they are a little unpredictable compared to a full sized heli but they are awesome to learn on. I’d suggest flying over grass to keep the parts count down Incase of a crash.

I think I have a K120 on the way

They’re actually good helis. They’ve got a K130 now that I’d like to get. They’re kind of simulator type helis in competition with Blade micro helis. They’re decent quality and have a beginner mode and an advanced mode. They basically do all the acrobatic stuff the 6 channel helis do. I’m more focused on my Oxy 2.
