3gx

If your Raptor uses NON-CCPM swash control (a single servo for the roll axis, a single servo for the pitch axis, and a single servo for the Collective pitch control), leave the setting at H-1, as you will need to continue to control the swashplate in this manner.

If your Raptor is one of the newer breed of Raptor that has CCPM mix (three servos working in unison to control the swashplate and collective, then you'll need to select the H-3 (or 120 degree CCPM mix).

When you go through the initial setup of the 3GX, it will figure out how your heli needs to have the swash controlled, and will set itself up accordingly.

You do NOT want to enable 120 degree CCPM mix out of the transmitter if your swash is a NON-CCPM setup.

-----

I'm not sure where you're seeing the information to switch to "H-3" -- I've looked several times through the 3GX PC step-by-step setup screens, and a couple different printed versions of the setup, and see no reference to changing from "H-1" to "H-3". Maybe it's in real small print.

3gx
I watched a few videos from freddy can fly on the 3gx and he states that the swash must be in a 3 servo/120 setup

Good luck with that. I know I wouldn't try flying a non-CCPM heli with my transmitter set to fly a CCPM heli.

Your heli will NOT want you to move all three servos simultaneously when you raise or lower the collective.

I don't think you really want all three servos to move when you command a left roll or a forward flipping maneuver.

If you set your TX to H-3, when you move the collective, all three servos will move. For a roll-axis maneuver, two of the servos will move. For fore/aft cyclic, you'll have three servos moving, one opposite direction from the other.

None of that sounds like it will bode well for your non-CCPM heli.

-----

Freddy might be able to fly, but I'll bet he couldn't fly a non-CCPM machine with CCPM mixing enabled in the transmitter.

-----

Before I supplied my original answer, I dug out a spare 3GX controller, hooked it up, and set my transmitter for a standard 1-servo per axis heli like your Raptor. I ran through the DIR mode setup, and the follow-on "teaching" portion where you show the 3GX what kind of transmitter setup you have. After all was said and done, with my transmitter set up for what is the equivalent of your H-1, all servos moved as expected. One at a time per axis.

I can guarantee that if you set it up as a 3-servo, 120 degree CCPM heli, your heli will not survive the first flight attempt. But the video your friend might shoot of the attempt would be a real laugh on YouTube.

There is no reason not to use the 3GX in your Raptor. It doesn't know what kind of heli it's in. As long as you set it up correctly and have adequate servos and power, it will work.

Set your transmitter for 1 servo per axis control, NOT 3-servo CCPM.

Follow the rest of the installation instructions. There is no reason it won't work.

Lets try...

Ok... Since ccpm is a channel mixing between aleiron, elevator and pitch... My concern is that pitch servo is going to move when moving ciclic... Not by radio but by gyro in 3gx...

Well, lets try...

Simple. The 3GX responds to your transmitter setup for swash control. It does not make it up on its own.

If your TX is NOT set for CCPM the 3GX won't override it.

Set your TX to ONE SERVO per axis control.

No Run...

Well, checking for 3gx installation, I can't get a right place to put 3gx on raptor.
Nose place is hi vibe location.... Boom space , narrow for receiver plus 3gx...
3gx on boom space and receiver on nose, we need to Run several extensions ....
SBus could be ...

Any ideas?

If this is a Raptor 50V2 -- it seems the ideal spot is the flat spot just behind the main rotor shaft, where you'd put the gyro. There's nothing wrong with that spot.

I assume you are using a Futaba radio, since you mention S-Bus may be an option for you. There's nothing wrong with that, either.

So you might need to run servo extensions from up front to the rear. Big deal. Secure them properly, go fly. Insure you have good, solid power to the FBL controller.

The reasons you give are not unique to a 3GX FBL controller, you'll have the same problems no matter what you choose.

As for high vibes -- I have four installed, two on a couple of 600 Nitro Pros, one on a Trex 700N, and one on a Gaui NX4. All front mount, all work just fine. You can deal with most vibration by the judicious application of mounting tape and perhaps a metal damping plate.
