I persume that is at zero pitch hard to say from pic. I had to shorten the longer one from the swash to the washout arm. On the manual it is link "C" and the inside should measure 37. Mine is 35.1. At zero pitch and 50 % pitch everything is bang on level and square including the servos. Another thing is are you sure your Jesus bolt is tight it looks loose. I also just noticed the link on you elevator arm looks very loose.

Edit.....if you have to tighten that link on the elevator level the swash again of course.

jesus bolt was not tight in the pic as i was pulling the head on and off..good eye! I am guessing by your statement that i was not supposed to use the link on the elevator arm as part of my leveling process? learn new stuff every day I will fix those 2 things and start adjusting link lengths. What are the other lengths you have for links on the head Valkman?

What I ment was the link is not tightened all the way in your picture. When you tighten it the swash will tilt forward. See the picture of mine. All other links are as manual. ALso if you look at the picture on the top of the carbon frame, on the right, I moved the brace rod into the inner hole and filed down the edge of the frame. Mine was hitting the inside of the canopy and starting to cause stress cracks in the paint and fiberglass. Yours might be ok but keep it in mind. Attachments:

OK so I tightened the link on the elevator control and re-leveled. Thinks were not as far out of wack with the swash being lowered some. I will have to check into that front brace thing, thanks for the tip! Mucho Bueno!

Now that looks better! Make sure all your servos are the the proper levels at zero pitch. Then you should get + - 10 deg of pitch. I run mine on -5, 0 ,5, 7.5 ,10 degrees in norm and idle 1 and that works out to be 25, 50, 75, 87.5,100 on the TX. If it was mechanicaly correct this would be the settings and it's correct with the pitch gauge. I don't do 3d so this is ok for me.

WTF...so when I started all this today I decided to start with a reset on the TX. Went through and reprogrammed everything before starting. Now when I hook everything up I have issues. First of all I had to trim the throttle down or it would just spin at bottom stick. Then when I try to spool it up it just seems to accelerate really fast. I have tripled checked the throttle curves and every thing is at zero at bottom stick except stunt mode. I don't get it I'm lost and spinning blades at zero throttle input is really sketchy. Glad I didnt have the blades on, fly bar paddles are enough

It will spool up quicker with no blades on. Let me get this right. You turn on your TX then your RX and the thing spools up even though its at zero throttle?? Are you sure you throttle trim is not up? If not that try re-bindig the RX. Then ESC reset if that does not work.

Rebound like 10 times...how do I ESC reset? 1 click down on trim stops it so its not too far off. I went out and spooled it up and you were right it was fast because of no blades. However, now I have gyro issues. I thought I had the tail all setup before I went out, as soon as it got light on the skids it wanted to yaw left real hard so I let off immediately. Now I've entered the setup mode and got everything messed up somehow. I guess I need to figure out how to program this gyro. I have the gt-9. I also have a JY401 I could throw in if this thing pisses me off too much. Seems like it's a better gyro though if I can get it to work.

what radio are you using , Futaba needs the esc in the radio or channel 3 reversed. as i found out on my first 450 build , it comes to life fast . never mind , i read a few pages back dx6i . not sure how spectrum is set up .

My advise is to start over as if you're re-programing your radio for a new model. I had this happen to me once before on a 450 and everything was wacked.

I am not sure if there is some kind of reset button or something...sorry, I know this is not much help. Maybe when trying to re-program the radio, you can go through setting all the parameters again on the GT9.

First of make sure you tail blades move in the right direction with stick inputs. Then make sure the gyro is not reversed. I think we covered that part. You siad you reset your TX so maybe these are off. Before you do any reset again make sure you copy your settings to another model profile on your TX. If these are all ok, and the model turns to the left when hoovering, move the tail servo DOWN the boom a few mm at a time. This will give it more right pitch. When it is nearly hoovering without turning use the links on the tail pushrod to " fine tune " it. Then when all is ok, turn off everything and restart and make sure it hoovers ok. This is the setup for some servos I have no experience with the Gt9 but if after doing EVERYTHING and it still turns try this. Most gyros nowadays you just setup equal throw each way and thats it. ALso if you do above make sure it does not bind the servo in each direction. And most important............. DONT GET ANNOYED !!!!!! Your nearly there and the more you do the more less likely something will go wrong and the more you know.

Whatever I did to the gyro isn't allowing me to turn at all now. The rudder servo doesn't move except twitching. I gotta figure out the gyro programming tonight.
