I’ve been using an eachine tx06 with my 2" quad. I was going to use the same with the 3" quad I’m planning.
But having spent several hours messing with the tx06 getting the camera to work (the osd and tx worked fine all the time) I’ve decided that really I want something a little more reliable. And also something where I can mount the antenna at the rear, so as not to get in the way of any HD camera I may mount.
I don’t want to spend much, but I’m looking for suggestions…
You can’t go wrong with the TBS Unify pro32 nano for smaller builds. With the camera what size does the 3" frame accommodate?
If it takes a micro size (19x19) then you can’t go wrong with a caddx ratel, they also do that camera in a nano size (14x14) called the baby ratel. I’ve used both in some of my builds also the runcam nano racer I used in my light weight 5inch build that does a decent job as well.
But like everything at the moment the unify pro32 nano VTX is out of stock everywhere I’ve looked I’ll still drop some links for you but just note they are out of stock
That’s a mini FPV camera (22x22) my only concern with a 3inch quad is weight, ideally you’d want to keep the weight as low as possible. So better suited to a nano or micro rather than the mini. I guess depends on what motor and battery voltage (1s 2s 3s) you’d be running and what 3inch props you choose a heavier quad is going to need more thrust to keep it in the air.
As for the VTX I don’t really have an experience with the pro nano as I’ve only ever used the pro32 nano and it’s amazing upto 1w of output power (check your local laws, I’m in no way suggesting you should use a higher power output than what is legally available )
As for crossfire, you should definitely look into it as you will never have to worry about failsafes ever again
Totally understand - crossfire is an alternative to flysky but more focussed on longer ranges.
So because of that, you get fewer crashes (failsafes) due to being out of range.
The theory is that a standard VTX will lose signal before a crossfire RX will.
The sixty9 combines crossfire VTX and RX in one so better signal from both for longer range but will of course need a compatible TX such as a tango 2 or a crossfire module.
I now have 5 drones and one in build that all use the same tx & rx so made sense for me.
I think the main purpose of a failsafe is to cut the motors when the rx is out of range.
In most cases you would set it to drop or to trigger gps rescue so that you can recover the drone without it flying away out of your control.
