Convert Typhoon H to PixHawk 6C Flight Controller

[1midniterider]

Is it possible to convert the Typhoon H to use the HolyBro PixHawk 6C Flight Controller? If so, has anyone attempted such a feat?

My initial thoughts are to completely remove the electronics and leave just the motors. So I'm thinking that I will need at a minimum for autonomus flight.

1) PixHawk 6C flight controller with GPS module
2) PM07 Power Module
3) PWM I/O module (two)
4) Lidar module
5) I2C splitter
6) cables

Eventually, add

1) Camera
2) Receiver
3) Remote ID

It's probably overkill...

I don't know if it is possible to add SR24 receiver to PX4 FW by settings. PX4 autopilot software has a subsystem for SR24. If so, you could reuse ST16.
In any case you will lose the ability to pan the camera.
To use another flight controller is of course possible if you replace ESCs and sensors. It gives you a lot of freedom.

Thanks for info... Right now it is still in the idea phase... The other option would be attempt to install the thunderbird firmware...

Your better off just repairing it, and keeping it Stock, rather than trying to Stuff 6-ESC's & Flight Controller under the Hood, that won't operate the Retract Modules, Sonar Modules, GPS Module, Navigation Lights, Status LED, Realsense, etc. The ST16 won't be compatible, and the Camera won't have Pan or Tilt... Other than that it should work fine...

I'm all in to help, I have several home builts and the parts are much better than having a mainboard with all the electronics installed. There are some very small escs, mostly 4in1 but there are so many advances today, I would use canbus on everything, holydro have good canbus escs, I think I will join along if you get started, except I would build on the H+ platform, that might eliminate you and your project. The platform is so good, the corp attitude straight stinks and downright screws you over, how anyone would purchase an 850 from them I just dont know. Terrible company and support

Possibly, but what is the fun in that.

Thanks for the info... I'll keep that in mind. I already have the H, which has gotten long in the tooth...

According to other another post on here the TH SR24 receiver is supposedly compatible with the PixHawk FC. I wonder what else maybe compatible.

Question... What is the difference between the PixHawk 2.4.8 and PixHawk 6C? Is the 2.4.8 a clone?

Hi I've striped out all the electrics apart from the motors fitted 4 Beatles 30 amp speed controllers and a mini pix FC kit from radio link. I've got it to fly but I can't get cgo3 4k camera to work yet. The biggest problem is ardupilot for is very complex for me

 

[1midniterider]

Nice! Did you get the landing gear to work? Have you tried using the SR24 receiver?

How did you connect the 4 ESC to the 6 motors?

 

[gibbo]

Hi , the q500 I've has only got 4 motors,I'll take a photo and post it..it's all carbon and ally no body work. I'm all radiolink, radio, reciver fc board etc. I don't what a Sr 24 is ?

 

[h-elsner]

SR24 is a ZigBee receiver 2.4GHz.

Here are two versions of it (the versions are exchangeable).

Ahh... I was wondering... The TH has 6 motors... The SR24 is the receiver in the TH. Which receiver did you use, if any?

Just for the sake of clarity the original receiver in the Q500 is also an SR24.

Did you attach a receiver to your Q500?

Today I ordered the:
1) PixHawk 6C flight controller with GPS module
2) PM07 Power Module

Let the fun begin...

 

[1midniterider]

My PixHawk 6C with GPS and the PM07 arrived today. So now where to start. Since posting this question I've read many of the other posts regarding the TH... I think I'm suffering from information overload...

1) The SR24 supposedly will work and hence allow reusing the ST16.
2) The Thunderbird firmware is an open source fork of PX4 that works on the TH, but... So that would indicate some of required components should work.. The landing gear works automagically.
3) The TH ESC's should work with the tap_esc functions, with some tweaking, in PX4.
4) TH GPS module may or may work..

So let the fun begin..
