Some fantastic engineering work there
Cheers for the comments I’m happy to do it
The amount of help all you guys have given myself and many others is really appreciated and without you guys passing on your knowledge I wouldn’t know where to start building a quad lol so if this build thread can help someone else out further down the line happy days. If not, atleast I will have had fun doing it
Next I have cut down the motor wires and pre-tinned the ends then soldered them to the race wires.
I then used the wire offcuts from the motors to attach to the otherside of the race wires ready to connect to the ESC’s. I used small cuts of heatshink to loop the wires around the stack screws to try and keep it neatish before soldering to the ESC’s.
Also fitted the Caddx Ratel Mini camera which is just 4 tiny screws through the side plate
Next I fitted the Unify Pro 32 HV to the back of the base plate using Extreme Odyssey Thermal Pad. They are used in PCs to help dissipate heat. They conduct heat but not electricity so this will insulate the VTX from the carbon plate while at the same time helping to dissipate the heat generated by the VTX. They come as a sheet which you can cut to size. They are sticky top and bottom but not enough to hold the VTX by itself hence the cable tie. I don’t know how well this will work but I’ll report back after using it for a while.
I have soldered the 9V and Ground for the VTX Power and soldered up the Tracer nano receiver to Uart 1 on the flight controller. I am running the camera direct from the VTX instead of through the flight controller (no soldering required just run the cable and plug in). The VTX uses a filtered 5V output which helps keep cleaner video feed.
Then I have soldered the rx and tx from the VTX into Ch1 and Ch2 of the Tracer nano receiver (apparently it give you better control of the VTX settings through Agent lite on your Transmitter than using SmartAudio)
Note* I plugged the flight controller into Betaflight via usb BEFORE soldering it up to make sure it was functioning and update to the latest version of Betaflight just incase there was any manufacturing fault (potential warranty issue if its been soldered first)*
This means you won’t have an OSD. Wiring the camera direct to the VTX is normally only done if the model hasn’t got a flight controller like a fixed wing plane.
You can still power the camera from the VTX if you wish but for the OSD the video wire will need to be soldered to the video in pad on the flight controller and the video out soldered to the VTX.
Oh bugger lol didn’t know that Deano. Thanks for the tip Gonna have to rewire now
Love the work so far @SirGunner. Did you solder in the capacitor?
Now I’ve seen that I’m considering doing the same to make more room on my build
Some times the camera has it’s own built in OSD that will display battery voltage but that will only work if you’ve soldered the VTX to VBAT or directly to the power pigtail. As you’ve soldered the VTX to the 9V reg the built in OSD of the camera if it has one will just read 9v permanently lol
I use these:
With one of these:
Looks nice and neat.
Thanks @Howard78 yes I’ve soldered the cap to the terminals of the XT60. You can pop the back piece of the connector off to reveal the pins but it’s a bit fiddly as you have to feed the legs of the cap through the back of the connector with the main wires. Keeping the legs short and soldering them is difficult. You also have to insulate the cap legs as if they touch n a crash you’ll have a dead short. The way I understand it, the cap filtering works better the closer it is to the board so if you can fit it direct to the board that is best mate
Thats cool cheers Deano. I want the full OSD so I will rewire mate
These look great Deano, might have to invest
I used some silicone sealant on the back of the little board to insulate the solder joints. Works really well on tight builds. As you said before if you have space it’s always best to solder to the board where possible though.
Also the 3D print is optional. It comes with heatshrink but I thought the 3D print looked alot neater
Thanks chaps , I’ll leave where it is for now
Fitted the VTX pigtail to the holder.
Fitted the tiny Tracer Immortal T antennas to the modified 3D printed GPS mount from of my other quad. Not ideal but will do for now.
Connected to Blheli_32 suite and checked motor configuration and direction (I’ve set to props out as after watching a video @DeanoG60 recommended on prop direction, I think this is the best option). Video link below
Gone through basic Betaflight setup, enough to get her up in the air at least. Now just need to rewire the camera to the flight controller so I can have full OSD and then she’s ready for her maiden crash lol
I use something similar for fitting heat sinks to VTX’s ESC’s etc. And it holds really well
Cheers for confirming Steve. I thought it looked pretty good to help stop overheating thanks for confirming mate
I have now rewired the video feed through the flight controller as @DeanoG60 recommended but have kept the power supply from the filtered 5v on the VTX. Tested and all looking good with the OSD cheers Deano
No problem glad to help out
