about to throw it all out the trash :)
Is it normal for the heli tail to go left when giving pitch/throttle to it?
I need to apply the rudder fully right to compensate and hold it straight.
Same on both helis. Caliber30 and Hummingbird CP.
I have a PG-03 Gyro on theHummingbird and GY401 on the Caliber30.
Its driving me insane getting these things set properly.
How can you tell if the gyro is planted wrong? Will it spin left really fast, and if its not itll spin left slowly because of torque in the motor?
What does the gain on the gyro do exactly?

RE: about to throw it all out the trash :)
Well I had my second few flights yesterday & throught tank1 I was having real problems keeping the dam thing from spinning round. So when I stopped to fill it up I noticed I has knocked off heading hold mode on the tx, switched it back and all was good!

RE: about to throw it all out the trash :)
Hi Velcomrob,
Yes it is normal that it spins counter rotor way, if you're flying in normal mode and if you didn't set a curve (or %) of compensation of you radio. If you did all that, I cannot explain, but if you forgot that, look in you radio menu for this curve and give it a little slop first and try again. Repeat the step until this effect disappears and you won't need to compensate anymore.
The normal mode is useful to trim your rudder right and set the link correctly so that you use as less trim as possible on your radio, then the servo works properly around its idle position.
When you switch to HH mode, don't forget to cancel the curve (or %) of compensation, otherwise you will notice this effect again (but on the other side).
Have fun

RE: about to throw it all out the trash :)
What do you mean didnt set a Curve %?
Do you mean pitch and throttle curve?
Right now its
P1 0%
P2 25%
P3 50%
P4 75%
P5 100%
This is the same for pitch and throttle. Im using a 7C Radio. Do I need less pitch more throttle or vica versa?
Isnt it better to learn without HH mode first? Also if your not in HH mode is it normal that your always trying to keep the tail straight?
I also noticed when I hit the rudder in a certain direction the tail will go crazy and keep going that way. What causes that?
The GY401 when its a constant red signal that means it is HH mode correct?

RE: about to throw it all out the trash :)
No they need to be diffrent.
Ok here is how my rappy is setup for learning! You only really need the normal mode for setting it up, just fly in hh mode to begin with other wise, yes you have to constantly control the tail and you will have enough going on already learning to hover.
Throttle position (Start it at 20% just about highest tickover without engaging the clutch)
1. 20%
2. 40%
3. 50%
4. 60%
5. 100%
Pitch position (% on tx degrees on the blades)
1. 0
2. -
3. +5
4. -
5. +9
The -'s you need to work out a nice smooth pattern so enter a valus inbetween. Watch the flybar against the pitch gauge as you increase the setting on the tx, when it lines up your there.

RE: about to throw it all out the trash :)
Its not your curves, as I assume you are hovering only and not throwing a lot of pitch chance in. If the heli is holding well when you remember to use HH but constantly wants to piro (spin) in rate (normal) mode you dont have it setup right mechanically. In rate mode the heli when turn in to the wind (weather vane) but should NOT piro with pitch/throttle changes (it may swing just a bit, but should be easy to compensate for). If you are having to hold in a constant correction to keep the bird from spinning even in an otherwise stable hover, you need to make adj. to the links. ALLWAYS setup the linkage in rate mode toget the rudder centered. Try this-
Training gear with free-spinning balls.
IN RATE mode, get the heli light on the gear, but not airbourn.
A spin during spool-up is OK, but when full speed is reached, the tail should react to any spin and stop it. It wont return to specific heading, its in RATE mode, but it should be steady if you arnt making collective changes.
If heli still is spinning, look at which direction the NOSE is turning. Let's say it is turning to the left (CCW), and you have to give constant right stick to stop it.
Throttle down and stop blades, engine running, TH on.
Look at tail servo. Is the horn at right angles to the push rod? It must be if the stick is centered in rate mode.
Now, put in LEFT stick, commanding a CCW turn (same direction the heli was spinning!).
Does the servo PUSH the linkage, or PULL it to transmit this command to the tail?
Whichever, it is doing this ALL THE TIME. If it is pushing, the linkage is too long. Pop the links and turn them in 5 turns each to shorten. Opposite if the servo is pulling.
Repeat the ground-hover test. Piro tendancy should be reduced, eliminated, or even reversed.
Make further adj. as needed until heli will sit light on the gear with no spin in rate mode.
Now you have a centered linkage. In rate mode heli should sit weathervaned into the wind in hover with only slight self-limiting swings in response to your inputs, and weathervane with direction of flight in FF. Flipped to HH, should remain locked on heading regardless of inputs/wind/flight direction. If not, you will have to play with other parameters like gain, but at least the basic centered linkage is good. Without that, your chasing the end of the rainbow.

RE: about to throw it all out the trash :)
If you are using gy401 it should not spin even when it it starting to lift off, just make sure that the red light is on and steady that means its on heading hold. if you cant make the light steady then your in trouble dont fly it. get an experience pilot to set it up. gy401's are very good gyro's you dont even have to trim the rudder it will compensate by itself to make the tail steady. no drifting no nothing steady like a rock even with a wind. trust me I have one on my caliber30 gy401 with 9254 servo.
cheap gyro's make your learning process a little bit harder because you are always moving the rudder stick going up to compensate any movement. trust me I have one of those cheap gyro's s
and they end up in the garbage.

Well I was trying to learn with HH mode off since someone said that was best
Let me turn HH mode on and see what happens.

RE: about to throw it all out the trash :)
you may want to check to see if REVO mixing is active. REVO mix should be disabled with the GY401 .
with the humbird cp this may not be the case, but im not familiar with the PG 03.
to set the tail rotor machanics. a good place to start is to center the servo and put the arm on at 90 degrees from tail push rod, ,move the trim all the way to left. and set the tail rotor as close to 0deg pitch as you can. then center the trim and you should be set close
to fine tune start in HH mode take off and hover switch to NORMAL mode and trim so the tail is steady. then land and stop the heli. turn off and back on in HH mode. now leave rudder trim alone.

RE: about to throw it all out the trash :)
lol 
what do you mean set switch to normal mode? Do you mean fly without HH mode on?
Also to set a rudder I should set everything at 0%?
Another question on gyros what do both dials do?
Gain 1 and Gain 2
Some gyros only have one gain, what does that do?

"Look at tail servo. Is the horn at right angles to the push rod? It must be if the stick is centered in rate mode. " What do you mean by horn at right angles to push rod?
When I set the rudder up shouldnt I center the servo arm to 90% and then the tail at 90% also? Isnt the proper way?
But yea im constantly using rudder control to keep the heli from spinning. I always try to set it up in Rate Mode as thats what I was trying to learn in.

RE: about to throw it all out the trash :)
This is for your gy401, turn off your revo mix, put your rudder servo in the middle, put the gyro on heading hold( this means that you can see a steady light on your gyro gy401), fire it up. Don't touch the rudder trim!!! or you will turn off the heading hold if you did this by accident switch off the heli and turn it back on. This are all done with the transmitter on. Now fly it, if the tail will not hold steady then there must be something wrong on your set-up either on the gyro or your transmeter. get an experience pilot and have him set it up.

RE: about to throw it all out the trash :)
Im trying to find a experienced heli guy down here.
When I set the heli in HH mode, I dont need to use rudder to compensate when lifting off?
Quattro, :P yes I am. Ive always been trying to fly and trying to keep the tail straight.

like i said bring it to me
just jump on a ship we will have you flying in no time
if its working in hh mode leave it there till you gain enough expeirience to set it up without it on oh and just to anoye you heres mine
with hands off hover

RE: about to throw it all out the trash :)
YUp, when its on HH your not gonna compensate on your rudder when lifting off if there is its just a little itsy bitsy tiny winy. but on mine no compensation at all, all I have to worry is my aileron and elevator. this only works on gy401, don't know about other exp. gyros.

RE: about to throw it all out the trash :)
Well im able to fly my Hummingbird CP now since I stuck the gyro from my FP onto it and it works.
Its all about he gyro. Im able to hover.
I think my rudder linkage is not setup right. whats the proper way to set it up?

RE: about to throw it all out the trash :)
Just make sure that there's no binding or it will take up a lot of juice from your battery. just put that servo horn in the middle and the gy401 will do it all for you, just make sure that it will move freely and if your using futaba 9253 or the 9254 turn on the gyro in digital mode so that you will get the most performance out of your gyro. Good luck and have fun

Some reason right rudder goes further then left rudder.
Im using the digital servo that came with my GY401.
