7chp Helicopter programming

[oxyfx]

I am not new to the flying hobby, however I had problems with programming my transmitter for the helicopter. My previous 6XEH was working fine.

What I am trying to achieve is to program the transmitter for 3d heli flight - which is not basic, so the manual does not describe this in details. Please do not send me to the manual - pages 67-69 do not contain any specific 3d programming information - just shady descriptions.

The following is needed:

1. Idle up switch set up for all 3 settings: lower position - basic heli flying (just hovering - if you advance the throttle the pitch is going positive and increasing from -2 to +8 degrees), middle position - throttle held at about 75-80%, up position - throttle at 95-100%.

2. For Idle up switch lower position the pitch of the main blades to be from -2 degree - to +8 degree, -2 is on the bottom of the throttle lever, +8 on the top.

3. For Idle up switch middle position and top position is the same from -8 to +8 degrees with 0 in the middle.

I did what I though was right, and connected the transmitter to the realflight G3 interlink adapter - enabling all 7 channels for the trainer and still could not do 3d. I was able to set constant throttle on the middle and top position if the idle up switch, however the pitch seemed frozen, it did not change.

Could somebody please send me step by step instructions on how to set the above up?

The swashplate type is H-1. I need step by step instructions on which menu to go in and what to set. I've read all related threads, but nobody seemed to get a straight answer and straight instructions.

Your help would be greatly appreciated.

Thx, Ox.

Have you gone into the Throttle Curve menu in the advanced menu and enabled Idle 1 and Idle 2?

[oxyfx]

Yes I did. It is enabled, and if I swith the switch it will throttle up accordingly.

[oxyfx]

Ok, maybe I am missunderstanding something here.

If I leave the Throttle Curve in the advanced for all positions of the switch 100,75,50,25,0 then the pitch works well.

However when I change the Throttle Curve for positions 1 and 2 to 80,80,80,80,80 respective for 2 - 100,100,100,100,100 it will nto change the pitch.

What am I doing wrong? I would like to have constant 80% throttle from the bottom to the top of the throttle lever - respective 100% on switch position 2 - the lever changing only the pitch of the blades.

I must be doing something wrong but what?

Your positive it is the throttle curve your changing and not the pitch curve?
With what you described, it sounds like your setting the pitch curve the same across the 5 points.

The Throttle menu should be labeled Tcrv and the Pitch labeled Pcrv.
Also you have to have transmitter in the Idle 1 and Idle2 conditions to set the throttle curve in each of those conditions.

Yes I am positive. To underline that, once I put the Idle up switch into position 1 or 2 the heli throttles up, and it will take off because it has a positive pitch - I don't know from where, adn moving the lever will not change that.

If I reset this model back to factory settings which are the things I have to change to achieve the above?

Thanks./

[DavidH]

Well here is just an example.

If you have the throttle curve in Idle 1 set for 80% across all 5 points.
Then the pitch curve in Idle 1 would look something like this. 0, 25, 50, 75, 100
Point 1 at 0 may be - 8 degs and Point 5 at 100 % may be + 8 degs.

The pitch curve should move regardless how the throttle curve is set up. If the pitch curve is not changing in Idle Ups. Other than how the pitch curve is setup. I have no idea what would cause it not to change.

Thanks.

There are actually 2 TH-CV and PI-CV setups. One is in basic mode, each of these have a (N) beside it - which I would assume is the normal mode, when no Idle-up is on.

Then there are THR-CRV and PIT-CRV in the advanced menu. Here I can set the 5 point curves. I go under THR-CRv and make sure mu idle up is on 1 also set on the top 1 - for switch position and I start setting the 80% all over 5 points. Same with Switch position 2.
I never touched the PIT-CRV (which by default has an (A1) beside it - no idea what that means.) - PIT CRV is the same over all switch positions.

Is this the right setting I should go with?

[DavidH]

Just for a Test.
Change the 5 points on the pitch curve in Idle 1. Make all 5 points for example 80% all the way across.
Then leave the throttle/collective stick at the very low position. In Normal mode, you should have negative pitch in the blades. Now flip the idle up switch to Idle one. The blades should change to positive pitch without moving the stick if the Idle up pitch curve is setup and working properly.

Trying to help you figure out what is wrong. It is difficult to do without seeing the radio.

So it is for me without doing this on a real heli. Did I mention that the transmitter is conencted to the Interlink of Realflight G3 - and I am simulating this on the simulator?

Do you think it is working in real but it gets translation problems whith the simulator?

Not to discourage you, but, I was never able to get my 7CHp to fully work with G3, while it does work very nicely with real helis. As a side note, I was always a little paranoid about using it anyways due to the fact that having it on with the antenna down is not good for TXes. I realize the the interlink doesn't feel the same, but it's better than blowing TXes.

[oxyfx]

Thanks, that makes me feel much better. I will go home, connect a receiver - and a few servos and see if it works that way.

David, thanks for all your help, I will get back to you guys after I did my in a real environment.

[oxyfx]

So, the radio works well in real environment - but it does not translate well to the G3 simulator.

Again thanx for all your help guys.

I dont like the wear and tear constant sim time has on my flying radio anyways.

[sky-t]

having it on with the antenna down is not good for TXes. I realize the the interlink doesn't feel the same, but it's better than blowing TXes.

Why would it be bad for the TX, what can happen to it, i have quite some sim time on my jr radio, have not noticed anything bad while actually flying for real, if it's bad, i'm going to stop using the sim?

[BarracudaHockey]

Some transmit some dont. If it transmits and the antenna is down the RF energy has to go somewhere so its disapated as heat, this is not good for the final output stages of the transmitter. You can pull the module or ensure its not transmitting when its plugged in but as I said earlier, thats a good bit of wear and tear on the switches and gimbles thats not needed, the interlink controller is fine for what a sim is designed for.
