Blade Inductrix FPV build working, and it's awesome!

Wonder if you can set return to home at x charge do it comes back before the battery dies.

With FPV OSD you can see the battery voltage to know when
you need to return.

I suppose if you don't have FPV OSD it would not be difficult to
add a battery monitoring circuit and MCU connected in series
with the Flight Mode Channel could place the RX into RTH on a
low battery voltage that you could
choose.

Problem with auto return-to-home is you may not have enough battery to make it back, particularly if you are far away and down-wind when you decide it's time to return.

That being said, none of my birds are large enough for this to be an issue. But with the larger one's that Jerry flies, yeah - auto RTH is a good idea so long as you trigger it in time.

Just noticed that they make a 5.2 Ghz transmitter module that fits the RunCam. So you have a quality video recorder and an FPV camera all in one! Kinda heavy though, so it's not really appropriate for a 250 racing quad. But for a larger bird, it seems perfect! Wonder what the latency is like...

I hear what you are saying... but if you fly out of line of sight I
would definitely have OSD to at least monitor the flight battery.

From what I've seen I wouldn't use a Mobius or RunCam for FPV
image flying.
The latency is a bit high for a speedy 250 quad. They would be
OK for larger slower flying planes.
It seems that board cameras have a much lower latency for FPV
flying and are smaller and lighter.

BTW...my BG 25mW Cam/Xmit units came in yesterday. Wow they
are small. Need to find some time to play....

Oh, I agree 100%. In fact, even on my 250 guad I have both an on-board audible and visible battery monitor/alarm *AND* an OSD to tell me the battery voltage in my FPV feed to the googles. I'm kinda paranoid about low battery levels after loosing my first 250 quad to the Dead River in Florida last March! (D'oh!)

My point was merely that a return-to-home won't always save your bacon unless you set it to be really conservative. But yeah, if I ever got into beyond visual range flying I would want RTH as well as OSD for battery voltage just in case!

Ah - OK, that makes sense since it's a digital system. The conversion to Analog prior to broadcast is sure to introduce latency, and that's definitely bad for high-speed FPV flying. It's my understanding that this is also the reason no one has bothered to come up with an app to use something like a Samsung Gear VR headset for FPV flying... In that case the conversion is from Analog to digital (to get it into the phone), but the latency issue is still a problem.

Yeah, they are all analog, from the camera straight to the transmitter. And it's crazy how small and light they are! (Especially considering how good the video ends up being.)

HAHA! Cool deal. Chris (Lazerjock) is using those same cameras from Banggood on both his Inductrix quad and his RC car. I'm running the Quanum Elite camera from HobbyKing which is a bit more expensive, but is otherwise basically the same rig. I just figured since my goggles are Quanum, I'd be better off sticking with the same brand. But yeah, at SELEM I was able to use any goggles to view my video, so it wasn't an issue. (In fact, my Quanum Cyclops goggles have a hard time locking on to the 25 mw transmitter. Takes a full minute to lock in for some reason. But it locks in almost instantly to the big 600 mw transmitter on my 250 quad. Go figure!)

I flew 5 batteries last night at work. (Had to pull a night shift to cover for someone on vacation, so I brought my Inductrix in and flew it around inside the control room building.) Tons of fun! Freaked the hell out of the cleaning crew at first, but one of the guys really got interested so I sent him a copy of the message above with all the parts listed. Might have just created another RC convert!

I know you'll have fun with that tiny camera, Jerry! Post some pics when you get it mounted!

PS: I removed the plastic housing on my camera before I mounted it on the Inductrix to save a little more weight. You can probably do the same thing with your Banggood camera if you need to...
