Heli loaded but no response

[aucmax]

Just received the Phoenix CD and downloaded the updated version "j" ? I assume this updates the drivers, video and sound. Calibrated my Futaba 9CHP. Loaded the Trex 600e sport by double-clicking and it appears on the field ready to go. Only one problem. Heli doesn't respond at all to my TX, no sound, only slow rotation of tail. Where did I go wrong? I tried going through the help file, but I'm stumped.

I don't know if it the setup is the same for a Futaba but, for my DX7 I had to set the swash to 1 servo. Not sure if that would cause no response like your experiencing. Just something to look at.

Well, I solved some of my problem. Needed to switch my new model to use in the sim to PPM mode. Recalibrated the TX. Had to reverse the throttle in TX. Now when I apply collective/throttle, heli does spin up but remains on the ground and just rolls/tips to the right and crashes.
I have a relatively blank model for the sim. Is this the correct procedure when first starting? I chose the Trex 600e sport which I assumed would be ready to fly, but I was wrong, again.

[zagiman]

That is pretty much what I did. I created a new model. I then set pitch curves linear and throttle curve to 100 across. Also set the swash to one servo (not sure what that is for Futuba).

Go to this thread and post #29. That is what I went by.

Also found the following in the downloadable manual:

Transmitter should be set to PPM (which you already did)
Disable any CCPM or swashplate mixing prior to using tx with Phoenix

I've read a lot of the manual. But I can't remember if I read how to disable CCPM or set the swash. I will check again. Thanx for the Dood link. Flick all switches? but not Idle-up or throttle hold? What were the Phoenix creators thinking? I wonder how the Dood new about these exceptions? I think they were mentioned in the manual but were vague. Directions to fail... Just what all noobs need. Go figure. I'm gonna try this set-up. Hope it works. And many thanx again!

Also found the following in the downloadable manual:

Disable any CCPM or swashplate mixing prior to using tx with Phoenix

Per manual:

"Make sure that your transmitter does not have any CCPM or swashplate mixing enabled"

How do I check this on my Futaba 9C? Does anyone know? How about setting that swash to 1 servo as in the above post? I am not sure I understand that one.

The "1 servo" setting just says that collective pitch is controlled only by 1 servo. Even though your real model uses 3 cyclic servos to do the job, the sim does its own mixing, so the transmitter just needs to send a single collective pitch value to the sim.

Thanx Alan
I understand. Makes perfect sense to me now. But, how do I set this on the Tx or in the sim?

The sim should already expect single channel collective pitch control. I don't know anything about your radio, though. Sorry.

I did a Google search. From the 9C manual, this is what you want:

HELISWH1 Type: Independent aileron, pitch and elevator servos linked to the
swashplate. Most kits are HELISWH1 type.

Also from the 9C manual:

I assume the 9CHP uses similar menus to the basic 9C.

SWH-1 is an "example" For the Trex 600, it's SR-3. And I have that parameter set in the new sim model. But thanx for the legwork. And I thought Saturday nights were boring? Maybe you do to. ;)

What I'm saying is that you should be using SWH-1 for the sim, even though the real 600 uses SR-3. SWH-1 is equivalent to the 1 servo swash setting on the DX7 and that's what I use in the sim. It will send the unmixed collective pitch, elevator, and aileron to the sim, which will then take care of mixing them together.

[aucmax]

I waited on the edge of my seat for you to tell me that! I baited the response. Sorry. But you are the man for all of the help you have given me. At least this now explains that "1 swash servo setting" (it's a DX7 description)
I can't thank you enough for spending your time. Bob should give you a sticky with a gold heli-freak medal for support. :thumbup:

[TheBum]

It took me awhile to figure out that the number of servos in the DX7 swash setup menu was referring to the number of servos that are mixed together for collective pitch, as opposed to the number of servos connected to the swash. Once I figured that out, it started making sense.
