Hi there, I'm having trouble with setting up my new Spirit Pro in my T-Rex 550E. I have DSMX Rx fitted and it's bound with the Tx. Collective stick works fine but the cyclic stick doesn't.

None of the options in the software seem to give me the desired functionality.

Thanks in anticipation.

Hi,

welcome in our forum!
To make it work properly, you will need only to reverse channels (Aileron and Elevator) in your transmitter.
So then stick movement will correspond to the movement of the cyclic.

Direction of movement in the Diagnostic tab does not matter. Important is only final result.

I tried this and it still didn't work properly.

First from all, you have to be sure if your Collective Pitch stick is moving with all 3 servos together.
From your description it looks like that you are at this point.

Then when you move with the Elevator stick, the swashplate should tilt forward or backward (other movement should not be present)
Is it true?

If not, did you disabled CCPM-120 mixing in your transmitter?

Thank you for a quick response. The CCPM-120 is disabled (Single Servo - Norm). Note that the Tx is at its default settings.

I know which directions the swashplate should move. It is not following the correct stick commands. None of the movements are logical and all servos are moving to some extent.

OK, so we have to start from the beginning.

Connect Elevator servo (servo that is in the middle) to the CH2 position in the unit
Connect Aileron servo to the CH1.
Connect Pitch servo to the CH3.

Actually CH1 and CH3 may be swapped, so important is only CH2.

Then you have to use Servos/Reverse and reverse CH2, CH3 or CH2 & CH3 to achieve servo movement so that during collective stick movement swashplate will go up and down (direction does not matter yet).

Can you get there?

Hello, sorry I had to do something. I'm not with the helicopter, it is in my workshop and there is no internet there. I can't bring the helicopter here until Sunday.

Thank you for the opportunity to go through it with someone but I must try again on Sunday with the helicopter here at home if I can't resolve it in the workshop beforehand.

Sorry, I'm not sure how to use this forum. I guess the question can go to anyone. When I flip the rescue switch, my SpiritPro does everything it's supposed to do. This brings a question I hope may be clear to one of Spirit's developers.

The Positive, or negative pitch depending on the situation during rescue is absolutely instantaneous. I mean no measurable delay at all. However, even though I now have the "Pitch Pump Booster" set to zero, the pitch response is quite slow.

Once again, upon rescue activation, full pitch is immediate and totally in control. In fact, it's so fast it's taking some time for me to get used to it. Being that the pitch response is so extreme, and so instantaneous, I'd say that proves my set-up to be very sound. If the pitch response was slow in rescue also then it would make sense to go over my set-up. That is not the case though.

I think that the pitch response improved as I lowered the "Pitch Pump Booster" to Zero. It's subtle though.

Help!

Hello,

if I understand your question correctly, your pitch is slow while flying, but with rescue there is no delay.

Can you measure angle of the main blades with enabled rescue and then in the normal flying mode with max. collective pitch?
Then we will see if there is any problem.

O.K. Yes you do understand the problem correctly. As soon as I read your reply I thought, WOW!, maybe that's it. I did check my 6 degree setting and my negative and positive pitch just to find they were where I thought I had set them. I did NOT however check to see what the pitch was when I activate rescue mode. So if it turns out that my rescue pitch is a few degrees more than my max pitch for normal flight, do I simply increase the "normal" flight pitch? I think the answer is yes I do.

I can't actually check until late tonight, but I bet you've figured my problem out for me. As soon as I find out what the rescue pitch is I will let you know. Thank you very much. Kirk.
