I was talking with this young man on another chat room. he usnderstands what and where all the swtiches are and we went over some things. The basic problem is what I had. Spool it up and the heli spins around and around. All I did on mine was put the gyro in "rev " and that was it. Not working for him. He would appreciate more help if you know.

hmmm, i was also thinking it was a gyro issue (it may still be a bad gyro but we'll check some other things). other than that it may be the tail servo is not centered.

check the position of the slider on the tail shaft and see if you have full range of motion when moving the rudder stick back and forth on the tx. the tail servo should be positioned such that the arm on the servo is at 90 deg and the slider is at the mid point on the tail shaft.

i'm just hoping that your problem has a simple fix...to see if you have a simple tail rotor rigging problem (as druss described) just feed in a lot of right rudder as you increase throttle and attempt to get light on the skids...if the right rudder stops the spinning, your problem is probably mechanical instead of electronic (which scares the heck out of most beginner eheli pilots.)...btw, if you're trying to lift off on a slick surface, with after-market heavy plastic or carbon blades, the spinning problem will be worse...just trying to help...ken

Pearl City eh? I remember the good ol' days at the PCT. Now it's gone forever. Sorry for the out of topic reply!

A question in conjunction with this thread - on my HB King 2, the servo horns have 3 holes across the top, and 5 holes down the middle shaft. On my 3 swash servos, the link rods are connected to the center hole out of the 3 across the top of the horn. On my tail rotor servo, the linkage is connected to the third hole down the middle part of the horn. 1) Is this the correct set-up, and, 2) wouldn't connectong the tail rotor linkage to the center hole across the top give a little mor range of movement? Is there an adjustment that should be made here? Thanks, Ken

hi ken...the center hole on the swash servo arms should be fine...if for some reason, the servo output shaft splines can't give you level arms at idle1/50% collective, i suppose you could try one of the other holes to get all 3 links the same length (since the stock xmtr doesn't have fancy settings, like subtrim)...the esky servo is kinda wimpy in torque...you're right about using a longer throw to get more tail movement...the problem is running out of tail authority because of the weak servo (made worse if you have binding in the tail mechanism)...in fact some guys have better tail authority by shortening the servo arm, thus increasing the power of the servo...you just have to experiment...or get a good gyro and tail servo, and be done with it...fwiw, most guys try to get as much servo throw and control movement as possible, but you gotta make sure that you don't 'hit the stops', stall the servo, strip gears, etc....hope that helps...another ken...

aaaah yesssss...the monkey bar...waitresses dressed in kimonos...bonsai tree garden upstairs...it's a chrysler/dodge dealer now...

here's a pic of my hbk2 with tail mods, and one of my logo10s...amazing technical similarity...

JUST SLIDE THE RUDDER SERVO FROWARD A LITTLE AND PLAY WITH THE RUDDER TRIM VERY LITTLE ADJUSTMENTS IT WORK FOR ME!!!

all right i got it to work thankx to you all expecialy Cyclic Hardover. THanx

Interesting to see that I'm not alone with the spinning problem. I have the gyro in Reverse. Tail rotor is neutral. I start the left spin while on the floor (carpet) and if I lift off I have an amazing spinning top in the air. I have tried by passing the gyro, looking to control it manually for a test run. No difference. I moved the tail servo forth and back. No difference. Belt is tight and rotor turns counter clockwise. Using right cyclic during lift doesn't help. Everything else on the bird is set carefully to tolerance. It should fly as well as my T-Rex 450. This has me totally wiped out!

The only thing that I can come up with for a fix at this time, is that I am planning on swapping out the belt. I recently applied a lot of pure silicone lube to the belt. Although it seems tight, perhaps there is slippage. However, in watching the rotor as I am running it up, it appears to be moving fast enough. That is....it appears to be.

My guess is that the problem relates to tail authority or that is the lack of it. After playing around with the gyro setting I don't know where or how to set it properly at this point. There doesn't seem to be any mechanical end points on that setting. But then again, I don't think that the gyro is my imediate issue. Or is it??? I welcome your thoughts. Thanx.....Rich

one quick test...it's normal for the nose to swing left as you spool up...that's because the main rotor blades are turning the other way...pull your motor wires, hold your heli in your hand and quickly torque the nose left...the tail servo arm and pushrod should move forward, thereby increasing pitch on the tail rotor blades to resist the torque...even without mods, the amount of pitch in the tail rotor blades (spinning over 8,000 rpm) should stop any yaw...ken

one problem you might want to check is the tail pivot assembly.the ball links to the tail blade holder needs a little play in it if you tighten the screws to the ball link connector it binds up and you only get a small amount of travel instead of full travel.with the bird on the ground and motor off go full left and right on rudder and makes sure the pivot goes all the way across the shaft

Thanks for your responses guys. I did what you suggested and all was OK in those areas. Today I was lucky enought to have an experienced pilot give it a go. After thoroughly checking it on the bench he spooled it up on the floor. First thing was his amazement as to the high head speed. He could not believe what that ESKY BL was doing. He dialed down the throttle curve a whole lot before he found it suitable. He also did some trimming and added expo. Then he was able to do a decent hover and pronounced it flyable. All during this test run the tail remained quite solid and he said that the gyro was doing OK for a rate gyro.

When I got home I powered it up and.....surprise!. The gyro would not lock in. The light flashes very, very fast for a few seconds, then goes into flashing about each second with a strong flash. That's it. No steady light. My guess is that this gyro is a bummer. Perhaps has been intermittent? I can get a replacement under warranty. However, should I upgrade this now. I am just a beginner and perhaps not able to appreciate the finer performance of a quality gyro anyway. But reliability is important. So, do I just replace with stock and see what happens.....or put more money into it now? What do you think???.....Thanks again for your help...Rich

hi dutch...all of my helis have futaba gy401s -- except the hbk2 which uses a gy240 that i had laying around...both are heading hold, and really lock the tail, unless you give input to move the tail...wind, turbulence, or the normal wishy-washiness of helis won't move the tail --unless you command it to move...sooooo, imho, you should seriously consider a good heading hold gyro...do some research because there are quite a few satisfactory ones that hbk2 flyers use...you should be happy about this 'upgrade opportunity'...most upgrade opportunities require ordering a lot of repair parts, and cause you to regress until you regain confidence to try whatever you were doing when you crashed...lol...ken

Ken, it sounds like the thing to do is to get something decent. I do have a GY 401 on my T-Rex 450 SE2 (which I have only just begun to fly). However, I have just learned another thing. Oh woe is me. I'm too old for this. But I found out that when my buddy flew the Bee today, he trimmed the rudder. I just learned that this lil ole rate gyro doesn't like trim. It will not fire up properly unless the trim is centered. So, my appologies to the E Sky mfrs. as there is nothing wrong with this gyro. However, I think I'll get a decent HH and then I can adjust it with the Tx too.

Thank you for your efforts in helping me!..........Rich

Hey Ken, you just totally sold me on the HH gyro. Just one question. Is it a straight swap from the stock to a HH gyro?? Or are there other adjustments that will have to be made to accomidate the new gyro??......Thanks.

it's a straight swap...the reason the 401 is so popular is the simple setup and cost vs. performance...plus, with a good transmitter, you can adjust gain with the transmitter...gain on the 240 is adjusted with a tiny screwdriver right on the gyro itself...it's just a hbk2, so i wouldn't go out and get a jr g7703dgyro w/ 8900g tail servo combo (i have one for one of my bigger nitro helis)...bottom line - find a good hh gyro and a fast tail servo (like a hitec hs-50 or fut 3154) and you'll be set...still gotta learn to fly though...lol...ken

Thanks Ken...So, a Futaba 240 hh gyro, with a Futaba 3154 tail servo should improve my tail control, for when the day should ever come, that I actually get to try my second flight?? Really appreciate your patience and understanding with me. You have great answers and you keep it simple.....rain

hi rain...good choice...however, as you do your research on gyros, notice that the 401 doesn't cost a lot more than the 240...and it's capabilities over the 240 are worth the cost difference imho...the 240 is great, but i suspect that software engineers can afford the difference...lol...before you snap the pushrod to the 3154, make sure that your tail linkage moves like silk, and your slider has full throw without binding...ken

EDIT: gosh darn (expletive deleted)...i forgot that you're probably using the oem transmitter...if so, you need to do more research and get more input from the guys who are using the esky transmitter...(maybe druss will jump in - he knows the 2100t gyro and stock transmitter)...sorry...ken

I agree with Fly to Chill. The tail servo needs to be adjusted forward or backwards to correct tail wander. If you are interested in hearing more about this there are some nice HBK set-up videos on Youtube from subzzzzzzzero. Here is a link to the first one you can eaisly find the rest. Good luck.

Ken...no worries brother. My very next question to you, was what kind of tx do you use for your HBK2. I am trying to get my setup as close to yours as possible. Two reasons. First, I know that it must work, cause it works for you, and second, you are really, really great at answering questions, regardless of how many times they have been asked before or how stupid they may be......Thanks..


Software engineer??? LOL....I wish...You know how hollywood has these guys with certian backgrounds, considered to be experts, consult with the directors and producers to make the movie more acurate and/or realistic. That is kinda what I do, except with video games. I couldn't program my vcr.....lol. Most guys in my field are contracted. I was blessed with the oppurtunity to be hired directly on. Thanks for the ego boost, though....lol

hi rain...i use a futaba 9chps to fly all my helis...it's 72mhz, but a lot of guys are switching to 2.4ghz...i have a futaba 6ex2.4 which i use to fly a giant super sportster plank (81-in wingspan, 17x10 prop, yadayadayada)...here's a link for my futaba 9chps...

however, imho, if i were in your shoes, i'd seriously consider a spectrum dx7heli w/ micro servo...like this one...

http://www.heliproz.com/prodinfo.asp?number=155781

your hbk2 will fly just fine with the stock transmitter, so unless you've already become a heli-addict, i'd do just like you're doing -- learning to fly and fine-tune the one you got...that in itself will take a lot of time and $$$...ken

here's a promotional video of the stock hbk2...this might be what got it all started...the brushed motor probably burned-out after that one flight...it's like a kung-fu movie...lol...ken

Thanks Ken....Think I will follow your first sugestion and go with the spectrum dx/w micro servo. I think my little one is gonna have to get a scholarship, cause after I done with this hobby, there ain't gonna be no college fund.....

As far as addicted?? I went to my LHS to buy a pitch gage, and walked out with several tools and another heli. A coax that I can practice with, while I wait for parts for my HBK2. I am getting ready to post another "how to" on my thread. I thought I would so people how to bling up their stock E-sky canopy, for people that don't want to spend money for some mass produced prepainted one....lol.....Its kinda cool.


That video was pretty funny......I will have to see if I can find it agian, but there is another one out there, that I swear, is a bunch of crashes spliced together to make it look like some kind of 3d flying circus.

....very funny!!!![sm=lol.gif]
