Went and flew at 60 acres today. only had time for a 20 minute test flight. the camera was out of focus and it was getting dark. This was flown with a foxtech 370 kv motor , two 5000 mah 6s lipos, APC 12x8, castle ICE 50 ESC, minum OSD and APM2.5 (data logging only for now)

This is from the logger on the ESC. and full log from ESC from the looks of it I am good for well over 3 hours flight time.

Thanks

Batteries capable of 3 hour flights tend to cause cameras to go out of focus, all free time to be taken up but 20 minutes, & they attract sasquatch after the camera goes out of focus.

From this test, I assume one 6s 5000 mah battery should last for 2 hours? One may not need three hour endurance for aerial mapping cos the camera battery won't last that long,

That is simply amazing what you've built here Wayne!

What amount of useful load can this configuration carry for 3hrs?

An important question, no point for it to fly for a few hour but do nothing.

@jack

 I guess you missed the 'squatch in that out of focus area.lol..

@keeyan

 ya thats what it looks like. I could have flown 4 hours.

@R_Lefebvre

Thanks, Its been a massive amount of work.

@Michael

 It carried an APM, minum OSD, camera, VTx, In all about .75 lbs worth of payload. and It could have done 4 hours possibly. Of course you could fly with less battery and more payload if you wish.

Wayne: I'd like to see more information showing how orthogonally oriented payloads can be implemented. I think you would do yourself a great service showing off just such an arrangement. There are a great number of FPV RC airframes out there, and yours is unquestionably suitable for that purpose. There are fewer orthogonal/NADIR ready airframes. 

Personally, I think you'll get more interest emphasizing a down-facing camera in an autopilot community than the forward facing FPV-style camera. After all, three hours is a workhorse but if you are cruising around with FPV, then you want to fly, not be along as the passive passenger. On the other hand, with an autopilot and a purpose (which is likely to be down-facing) the FPV capability is good for orientation, mission monitoring, and takeoff/landing. But the application is in showing off that payload flexibility...

Wayne, how well will this fly in a wind?  I'm worried about the cruise speed being a low-ish 30 mph, with a max of 55?  What happens if you were flying in a 20mph wind?  If you need to go upwind, could be a bit of a chore for it?  How much power would it take fly at 50mph airspeed?

Also, do these ship out of Australia?

Robert - per the website, for Australia, contact admin@boltrc.com 

For your purpose, I believe you'll find they ship from Washington State. Lynnwood, if you are interested.

Oh, OK.  So you have distribution in America, that's basically what I was interested.  I saw that comment about Australia, and wondered if it meant they were all shipped out of there.  I couldn't find info on it.

It might also be helpful to people if you did something like outfit one with 3S or 4S 5000mAh battery, carrying a camera, and show it doing a 1 hour mission.  Something like that that is more of a typical mission.
