Why on earth would you convert the king over to a motor driven tail. That's just a major step backwards...

Remember a few months ago, when all King`s owners try to figure out the tail-vibrate problem with a Brushless high speed main-motor...

I think that`s why..

I did this because the tail shaft drive train couldnt handle the HS that Im running. It broke and if it didnt break, it would make a strange noise on spool up, then it would finally break.
If there was a way to slow the tail down through a larger tooth counter gear than this would maybe fix the problem for a while.

Im also able to run different sized blades from the CP2 240mm all the way up to 300mm, since there is no shaft or belt in the boom I can slide it back and fourth to accomodate the clearance needed. The aluminum main shaft has been replaced with a Trex hardended steel unit. The HS on this king is over 3000 and even more with 240mm blades. I have taken the mechanics of a crown gear, a tail shaft, a tail rotor shaft, a PC lever, tail rotor grips, linkage rod, and servo, and replaced it with a single 20mm motor, that will probably outlast any servo or part mentioned above. Sometimes you need to take a step backwards before you can leap forward.

The heli has never flown better before this mod.

wow how fast were you running the headspeed? Many people are running it up to 2500-3000 rpm no problem with the tail but at 3000 you are really pushing the structural integrity of the head. Even a t-rex is not suggested to go over 2400-2500 on the plastic head.

E-sky also just released a completely new tail for the king/cool.

I still would never go back to a tail motor. No way. I would have just switched over to an MX-400 or 3D Pro with the belt drive and ran the king with the lower headspeed. It's not a t-rex

Hi L0stS0ul, about the completely new tail-boom, supposed to be steel instead of carbon drive-shaft with 4 bearing instead of 2... is it really true or a rumor ? same part number and Esky is speechless about it...

Hey, Martin - haven't heard from you in a bit!! As for the new tail for the King, I haven't heard anything about the extra bearings, but I'm pretty confident that Esky has modified their tail booms - I just think they're a bit apprehensive about saying so due to the problems before. As you know, I have had my King spooled up pretty high, and it hasn't shown any vibrations at all; even more, all the new King owners I have talked to haven't had any vibe issues, so I think this is a closed case with new Kings - problem resolved.

As for you guys who are running super high head speeds, you may want to jump on the all CNC head Esky will be realeasing - supposed to be this June, from what they told me - message below.

Dear Larry:

Thank you very much for your email and choose our products. the upgrade parts will be released after 3th shanghai model exhibition(June 3-5th) . So it will be available in June.

Best wishes

Linda zhang

Martin - did you receive my last few e-mails? Haven't heard from you in a few days!

Gobe bless - "Rare Bear"

Overseas it looks like E-sky is giving it away as a free upgrade. It will be interesting to see if the vendors over here do the same.

L0stSoul,
I didnt want to invest in a 400 class machine like the MX400 or the trex. I already have 2 QJ8s. many of the parts I have on the king I already owned like the CC35 and the 3500kv motor and the GY240. A trex or an MX400 wont run for 8 mins on a 1000Mah lipo. The tail isnt as good as it can be but its beter than it was, my tail would simply piro on a whim, causing a crash, and it would do it again and again even after fixing up the entire tail box with new parts, new servo new shaft, new tail, I almost threw in the towel with this heli until one day out of bordom I decided to graft on the tail parts from my CP2. The HS im getting is only possible because there is no parasitic drag on the main gear other than the rotor head, combine that with a mini raptor head and a one way bearing and you have one extremely agile machine. This king will roll and flip while in hover, and its still only slightly bigger than a CP2 but substantially smaller than a TREX which makes it more fliable than any other machine out there for me because I fly it more often in small spaces.

Isn't the TRex shaft shorter than the original one? How did you deal with this?

Finally got a little video of my heli. Nothing to special just doing circuits around the field. I'll try to get some more advanced video next time. I just redid my programming and didn't want to push the heli to far till I knew how it handled. Happy to say it handled amazing

Here's the link to the video

Man thats nice and looks very stable. How fast of a head speed you running? And are you running the esky blades? I ask that question because in my readings I have heard the esky blades are not that good and using blade cp ones are alot better. This has to be true in some sense because when I tryed esky blades on my blade cp it flew like crap and I took them right off and put back the blade ones back and flys so much better. I am having a problem with my rx and may have to send it back to futaba. I can't get any servo movement from the reciever and its a brand new one. Took it to a hobby shop and the guy couldn't figure it out even using a diffrent rx so I'm currently grounded. Gotta love the trials and tribulations of this hobby Jimmi

I'm using the stock King blades. Mine came out of the box balanced almost perfectly. They also weighed exactly the same. I think the Blade blades on this thing would be way to small. E-Sky will have some CF blades out here in the next week or 2 and those will rock. I've not had any issues with these though. Once I set the pitch to be equal on both they just tracked true. No issues at all with them.

I don't have a tach so I don't know for sure what my head speed is but from the calculations it's between 2100 and 2200rpm.

Oh I know very well the trials of this hobby lol. Sometimes I think vendors send me their defective units just to see how I'll react
