ok I got everything so it's working the way it should. so how do I set up my pitch curves and what menu do i have to go into to set them up? I'm sorry for all the questions but i'm new to the computer radios for the aircraft, and the manual that came with the radio doesn't make a lot of sense when they try to explain how to set things up.esky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

I looked at your radio manual. Your radio is a bit different than what I'm used to.

I looked at the manual for your radio.
You should have C3PF or C3PB depending on your heli.
You need to make sure that you have the servos arranged per thier diagram on page 76

It looks as if you select the correct type of swash (C3PF or C3PB) AND you arrange the servos as they describe then all you do is reverse the servos until you have the swash going up and down then the cyclic should work.

yeah I switched the plugs for the pitch and ail servo and everything started to work like it should. I even got my pitch set. now the only question i have is will I have to set up the throttle speed and pitch for stunt mode or do I just have to set up the pitch once? so now all I have to do is set up my tail rotor to hole the tail steady and I should be good. anyway thanks for helping me and putting up with all my dumb questions. this is the first computerized aircraft radio i have ever owned. I have and Airtronics mx-3 radio for my truck but it's a lot simpler that and aircraft radio.esky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

once you set your max pitch range mechanically with the radio at 0-25-50-75-100,all further adjustments are done with the tx,you set all of your flight modes independant,once you get the hang of it making adjustments is easy.

oh and the airtronics is a nice radio,good choice and good luck,you should have a much better time now,dont be afraid to try some expo too,makes hovering in the beginning easier

any other ???? just ask

I would start out with linear throttle cruve for

Normal 0 25 50 75 100 and 40 45 50 75 100 for the pitch.
If you think you need more head speed you can adjust throttle curve point 2 to 4 I run (0-65-90-100-100).

Idle up ( stunts ) mine is set Th 100 100 100 100 100 for pitch 0-25-50-75-100.

Did you set it up mechanically so that you get 0degrees pitch at 50% pitch on the Tx?

SOOO much of how well a heli will fly is how you set it up mechanically and the curves.

Ice, this also worries me, because you said nothing about mechanical setup and probably you should have questions there.
I will even make Mel's statement even stronger - if setup mechanically wrong (i.e. not perfect), heli does not fly, extremely for beginner. Well, not true - it flies, but very short time (1-3 secs) before crash. Been there...

what do you guys mean when you say mechanical setup. are you asking me if I went through the head making sure that all the links are the same and everything level? or do you mean setting the pitch with the trim on the radio and a pitch gauge?esky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

Yes, that's mechanical setup, including setting pitch at 0 at 50% throttle. That links are proper size, everything properly level, etc. Yes, head setup. If you did this, that's perfect, sorry for pinging.

40 45 50 75 100 for the pitch.
Nothing wrong with these numbers.

However, this needs to be verified with a pitch gage.

For normal mode, I like;

-2 degrees low
+7 mid, this is good for hovering
+12 high

You NEED to do this before any test flights.

Others might prefer slightly different pitch curves, but they will be close to this for "normal mode".

okay thanks for the help guys, I got everything set up and like how the heli lifts off now but I can;t get the tail to hold no matter what i do. and no matter which way I have the gyro switch on the tx flipped do you guys have any tips on how to set up the gyro so that it will hold the tail? and which way should the gyro switch on the tx should be flipped for rate mode up or down? I'm going to try putting my hs-65mg servo on the tail just to see what happens. but any tips you guys could give me would be great. thanks again.esky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

What gyro do you have? There should be somewhere so called 'gain'. If gain is too low, then tail does not hold, if too high - it wags. You may need to find how to set it up on your Tx, if gyro allows this (4 wires from gyro to Rx, 3 for gyro itself, 1 for giro gain control). If only 3 wires from gyro to Rx, then there should be dial on gyro, which is for gain. At least heli does not spin like crazy?

Good comments KV

There is also a "shake test", to be sure things are right.

This is in addition to everything else.

Is your gyro mounted correctly?

guys,I have the esky head holding gyro, and it has the signal wire and the normal 3 corded wire? so I plugged in the gyro according to my rds 8000's manual but the manual doesn't say which way the switch has to be flipped for rate mode and which way to flip it for head holding mode? and the gyro also has the limit and delay adjustments on the gyro itself. I have the gyro set to 100% in my radio? also how much pitch should the tail rotor blades have to hold the tail? thanksesky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

I do not know your radio, so I cannot comment on it. In any case 100% is way too much. Tail should wag (bounce from side to side) like crazy in this case. If it is not, then your 100% does not have effect probably. Rate vs HH mode is switched by gyro gain. Usually if total gain range is between 0 and 100%, then from 0 to 50% is rate, from 50 to 100% - HH. 50% means in this case - no gain (as if no gyro). There are cases when range is between -100% till 100%. Again here, lower half is rate mode, upper half is HH mode. There should be indication on gyro, when it is in HH mode (kind of light on), although you do not want to tell the model of your gyro. There are at least two esky HH gyros, which I know of.

Usually there is no switch for rate vs hold - though on some radios it can be programmed, but principle is the same as above. Gyro gain is important. I have no idea of your Tx, so cannot comment. (That's what I warned way before - limited community support, because no one knows your Tx).

I'd recommend you to try the following - disconnect signal wire (usually jack with one yellow wire) from Rx. Usually in this case gyro gain is controlled by dials on a gyro and see how it goes. Maybe gyro will be in HH mode. I do not know, but easy to try. As far as HS65MG is slow servo, set some delay - not much important for hovering. Set it to the middle of dial. Delay is controlled only from a dial, not from Tx.

Tail blade pitch - maybe around 4-6 degrees, but it does not matter for you, because you will never set this, unless you are super-pro and squeese everything out of heli. Generally neutral position is set in rate mode by adjusting servo position so heli does not rotate in hover. Then when it is set, gyro is set to HH mode. This is not for every gyro, but should be in your case. This sets proper tail blades pitch.

What's the model of gyro? For example: EK2-0704A.

Does heli spin or tail does not hold? More details please.
Please note, gyro should be properly mounted on heli. It is possible to mount it to be reversed or in a way that it does not feel rotation.

If you have two dials on gyro and it is esky one, probably it is Ek2-0704B.

That's what written about it:
Installation:

The EK2-0704B headlock gyro must be installed horizontally (LED faces upward)
the headlock gyro (3pins) cable should connect to the channel 4 on the receiver
the tail servo should connect to the headlock gyro

you can choose not to connect the single orange cable to channel 5 on the receiver. if the gain of the headlock gyro > 50, it is in the head locking mode. If gain < 50, it will be in the normal mode

Try to follow this instruction without connecting orange wire to Rx.

If it works, then you can try to program your radio.

yes my esky gyro is model number ek2-0704b. and yes the body of the heli will spin when it is off the ground. which is what i'm trying to solve. I will try flying it with the signal wire of the gyro disconnected in the morning and see what happens. so it doesn't matter which way the gyro switch on my radio is then?esky belt cp 450, just built exi 450 pro, trext 500esp, trex 600esp

Ok. Stay with wire disconnected for now, then Tx has no effect.

Disconnect motor and do the following:

1. First check if tail reacts proper from Tx. Left stick to the left - heli nose to the left. Without launching heli, look how tail rotor rotates and how it deflects. Try to figure out if tail reacts properly. I especially do not tell you direction, cause you may have reversed tail rotor direction.

2. If it is Ok, then rotate powered on heli by hand (disconnect motor) and see how gyro deflects tail blades. It should counter interact with your rotation. If not, reverse gyro (there should be switch).

When you are sure that 1 and 2 are OK, connect motor, then try to set gyro gain say at 70, launch heli and see how it goes. Tail should stay or drift a bit.

We'll continue from that further.

Please let know how is all going.
