I’ve been looking for a quad that’s as small as possible, but that can carry a Vista set up. Walksnail and HD zero have got on this quickly and both have tiny whoop sized 1S stuff but Caddx (and now RunCam) don’t seem to have got there yet. There’s a couple of options out there but they’re all skywards of £300 (e.g. iFlight Alpha 75 and 85) or not in stock (like an awful lot of things still atm - e.g. Tmotor Tron 80 HD)
So I took a punt on a kit from UMT on a ‘CineFlea 2’ which is basically a not-constructed HappyModel Cine8. £85 - and it’s a bit of a bargain at that price (with a couple of caveats! - see below) and I’ve had a vista vtx and polar nano camera combo sitting spare which I bought as a back up when Caddx and DJI fell out. Thankfully, RunCam have now continued the line so my bloody expensive V2 goggles now won’t be a brick anytime soon.
First thought was genuinely oh f********ck. What did I just buy! 
But tbh, it went together pretty sweetly. Barring one minor and one pretty major snafu. Thanks to some top pointers from @GunjaFPV in an earlier post, I knew that 2 of the motors were reversed and were marked with red dots.
Only one of these has a red dot. 
Fortunately really simple to just reverse one of the motors and it then flew pretty sweetly straight away.
Major problem arose though when I then plugged in the VTX. It shorted the main FC and prevented it from booting. Very very lucky it wasn’t a magic smoke moment.
At least one of these wires is not where it should be… 
I shall definitely let HappyModel know as I’d has been seriously ticked off if I’d wanted to actually run this on analogue and it arrived in that state.
Fortunately, I didn’t actually need any of that so I removed everything except the GND and 5v lines and then soldered wires on to RX2 and TX2 for telemetry data from the Vista unit.
The Vista is 25.5 x 25.5 so is a perfect fit on this frame. I 3D printed a mount for the vtx and moved the battery to the underside.
The whole thing comes in at bang on 100g.
I thought it might be too similar to my ProTek… but I don’t think I need have worried!
I’ve only had a chance to do a couple of flights, but it flies really smoothly. I turned down the rates a wee bit as on 3S it was pretty lively and certainly no way underpowered. Just cruising around I was getting just about 5mins on a 450mah 3S lipo.
It’s clearly a whoopy thing and not designed for extreme acro, but to get HD vid on something that weighs 100g is pretty 
in my book.
I finally 3D printed an antenna mount and a small protector cage for the Vista as it’s a bit exposed on the top. All in all I’m stoked at how well this works and am looking forward to some decent calm evenings to try it out properly.
Couple of quick test laps… (It was way too windy for this little thing when I was out by the church, was gusting to about 18mph)
