One suggestion here, get a pitch gauge, they're cheap and a quick way to determine what's going on. Measuring links on someone else's heli is a rough starting point, but not a good indicator of where yours is at.

Some obsolete nitro helis too...

Tryan,

I am using a brushless 3900 with a 10t (did my homework teehee!)
The rudder servo will be quite easy to figure out if the problem is caused by the pitch of the main blades.

when you say it does not move, how fast can you turn your tail left? CW overal? I am certainly ready to fly if tail does not move, have spent many hours on G4.

I must have move this thing 1000x by now, gyro inverted and back to normal another 1000x, belt tension another 10,000x.

will post the results later tonight, Thanks again!

Yea,,,,,,if he has no point of refferance, we need to get him at a starting point. Making sure trim tab is centered. Then when he turns on the receiver it will pull the servo back,( to neteral) at least close to whAre it should be, you say +15,and a starting point for ajusting the push rod. I have to go get a Deg. ajuster yeat. Standing at the back, and looking down, they sure looked at about zero Degs. push rod pushed towards the back, or - pitch.

Whats Gfor? I aint got G1,2 or 3 yet.

thats a lot of motor for a new pilot you should probably drop to 8 or 9.

As far as how fast my tail spins this vid will show you piros both directions.

Tex are you understanding hes talking main blades first not tail? unplug motor and go to idle up center throttle stick and eyeball 0 degrees both mains and flybar paddles. Then get a pitch gauge you can download ones for cardboard on the net.

To end confusion of my degree measurements heres some photos. No rudder input servo centered. I dont use trims I mechanically setup my heli so I dont need them. I apologize for the tailbox photo but you can see the yellow tailblade angle and guess about 15 degrees at center everything.

Now im confused............! thAre I go talking and not knowing anything im talkin-about. I took it as everytime he tryed tp spool up, the body would go CCW. I took it that the body wanted to go counter clock wise, thinking the tail pitch is to much, or to little."Sorry" Maby im to old for the new tec. stuff........?

Your on the right track tex I agree this fellow needs someone to check his setup from the main gear up. But If you go back to the title he thought his problem was the tail spinning due to the main blades pitch off. I found that hard to believe myself but it is messed up so we've got two problems confusing the issue. We really need to get back on track for one or the other. We are trying to convey total setup through typed word is not gonna work well for this one.

So Back to original poster this heli is not air worthy as is.

1Do like I said motor unplugged in idleup with the throttle stick centered 50% throttle Knobs hover and pitch at 12 O'clock. You can eyeball both blades and flybar paddles to 0 degrees.

2. Spool it up in normal if tail still spins CCW we'll go from there.

What is CCW? Im thinking CCR,so im way out in left field now.............!!! yr last post is what I would start with on the main, then go to the tail. Knobs hover and pitch at 12 O'clock. "Please" tell me why we have them, and how to use them........Please ! And yes, we did not make sure he was at zero on the main@50%.

I am only conveying what others have told me and I have read the radio manual I never had the pleasure of a stock radio. You have a knob called hover pitch this is what it says it will adjust pitch a degree or two on the fly you keep the same range it just goes up or down like -2/+9 up to +1/+10 for a more stable hover. The other is for Idle up or stunt mode so youll flip the switch and have full pitch control from around -9/+9 and adjust the throttle speed at differnt curves within those pitch ranges. thats a little confusing but If your doing stunts you want a lot of headspeed all the time and when you give full collective you'll want even more. A lot of 3D pilots run a 100% throttle all the time and the left stick only controls pitch this takes a programmable radio.

Thanks, I'll have my Futaba 6ex by the time I get to take it up in hover, but wanted to know just becouse thAre thier. I just got done watching the 2 vids of hovering in "The Green-Room". We Neaver could hover just inches off the ground. Nice Work. Wonder if the Gyro is helping ya......? The book I got with the King, tells nothing about the transmitter, thus "Smashing The King Into the Dishwasher-&- Floppin Around on the Floor", Spittin Out Pieces EverywhAre...! before I got close to blade tracking. By the time my radio gets here, I should have it dialed-in, and ready to jump it up in hover. Thanks & Nice Stick Work !

Thanks TEX the gyro is a pricey futaba gy240 Heading hold gyro. It keeps the tail perfect even with a inferior E-Flite S75 servo. Its not me my skills are average its just well setup. As far as manuals your right you have to go to the official E-Sky website and read the Radio manual heres the website.

Tryan,

Holy crap, I have control of the tail! Holy crap!!!

34mm and... well you will never guess what was wrong.. Charging up that battery and getting it out of a real test.

For you noobs out there: dont give up! it took me over two weeks to figure it out but I 'think' i did it!

I did not take it very far up for my first hover attempt, but enough to bite my lips a few times!

I think what really led me was when I remember you writing:
"those machine aren't that complex", so true once you find out the little problem causing the big one!!

Here is how it all happened, I started up the heli and about half throttle heard a big "vooooooffff" I thought it was the belt: checked... no do not look like it.
Try again: Vooooofffffff, I pick up the heli and it was that tiny piece of plastic coming out of the one blade from a previous very small crash in the backyard.

I removed the entire plastic and here it was: Perfect control, actually, too much CW!!!!! so happy!!! thanks!!! now patience is the key I guess
