Thanks, Chipwhich, this is very helpful.chipwich said:Hi, this is my first post, so greetings and salutations.
I've had two Phantoms, P1 and currently a P2 v2. I used a Futaba T8FGs which will bind directly to either P1 or P2 internal receiver. If you have a P1 with the upgrade board for the H3-2D, it is really easy to bind because the reciever's bind button is reachable inside the battery compartment upper right hand side. For P1 without the upgrade board and P2 owners, you have to take the top of the shell of to access the bind button.
However...now I fly with an X9D for everything.
FrSky Receiver conversions for Phantom 2
Since I've migrated my fleet to FrSky Taranis, I removed the internal receiver on the P2 and installed a FrSky X6R. You don't really need the X8R, but OK to use if that is what you have. I have done 3 X6R conversions now, so can do one in about 20 mins. You actually don't need to remove the internal receiver either, but why have the weight and clutter.
Need: 25CM FrSky antennas (available from you FrSky dealer) and double-sided tape
1. After pulling the top shell, you remove the four screws holding down the Phantom's main board. That will allow you to move it around slight to get to the two screws holding the internal receiver. After removing the receiver screws, save them in case you want to revert, especially since they are different lengths.
2. Remove tape on the stock antenna leads and pull them through their applicable holes.
3. Disconnect the two servo cables at the RX. They are hot glued so go gently. Scrape off the bits of hot glue on the ends that will go into the X6R or X8R. I use channel 5 on the Taranis for gimbal pitch, so I connect the NAZA's X1 to port 5 on the X6R, and X2 to the S-Bus port.
4. Pop off the X8R or X6R cover, gently remove the stock antennas, and replace with the 25cm ones. They seem like they don't fit, but with a firm press while gently rotating side to side, they will pop on. They are a tight fit, but I add a little hot glue, because that's how they come from the factory.
5. Use some double-sided tape to stick the X6R to the side of the NAZA so that they are side by side with the servo ports on the receiver on the same side as those on the NAZA, because you will be using the short servo cables that are already in place on the NAZA X1 and X2 ports.
6. Thread your new antennas through the same ports as the stock antennas. Tape as needed.
7. Put the Taranis in bind mode on Page 2 (Model Setup) and while pressing a hex driver on the bind button of the X6R or X8R, power up your Phantom. I'll assume that you didn't install your props because the top shell is still off.
8. After about 10 seconds, let up on the bind button, and power cycle your Taranis. The RX status light should change to green indicating bind.
9. Put everything back together except for props, run Assistant and go through the stick and X1 calibration as you do with any new NAZA install.
10. Optional (I do it). Open your Taranis and convert the throttle side to center spring mode so that hands of your Phanton will stay in position in GPS mode. Takes 5 mins.
How to get smooth video:
1. Add 40% Expo to Aileron, Elevator, and Rudder on the Taranis Input screen (page 5). This will greatly smooth you inputs just off center points.
2. On the Mixer screen (page 6) add 8 sec to Slow Up and Slow Down on the channel that you are using for gimbal pitch.
3. On the Servos screen (page 7) set your Subtrim to place the gimbal in the position that you want when the rotary is at the midpoint or detent. I like to use LS and -25 for this, but of course this is personal preference. Play around with the end points to get the desired motion and max/min pitch.
4. Use a 3 axis gimbal if you can afford one. The H3-3D is not perfect but getting much better with latest f/w.
Hope this helps.
Cheers from Atlanta.
Regarding the antennas, why use the Fr Sky 25cm antennas instead of the stock DJI antennas already in place? Sorry if this is a stupid question, but they look very similar.
Also,I was easily able to set the throttle to spring center, but there is some slop in it and I can't figure out why. The other gimbal is totally tight.
Any ideas?
