459MHz UHF legal Tx and Rx - Arduino based programability.

More than enough for me Nigel, Looks like it performs well,Have you had chance to fly with it yet?

[Devonian]

Not as yet, been on holiday!

Im very close to getting this, As soon as I hear your report on it Nigel I will make a decision, but its very tempting.

Yaaay finally got my 11dbi patch antenna for my vid syatem.

Now waiting for some good weather to do another flight.

In the mean time, Im trying to build a diy antenna tracker.

Flytron email today saying the LRS Futaba transmitter module back in stock

Yup :) thinking of getting another rx module myself.

I also got the email and ordered a set, plus the Futaba adaptor.  I'm looking forward to giving this stuff a go.

I also ordered one of the Turnigy 9x radios which can be re-flashed with an open source firmware.  The OpenLRS will fit right into that.

I also ordered an Open Pilot Copter Control yesterday as well!  Yesterday seems to have been open source day for me!!

Now where are the details of the programmer jobby I need to go with the OpenLRS.  In this thread somewhere I believe.

[thundead]

Haha very nice :)
you will need a 3.3v FTDI cable. Think u can gwt one cheap from coolcomponents or even ebay.  I'll post a guide on how to program the thing later on :)

Just a point on this kit...

If it's not truly LRS and the range is no better than a Futaba 2.4 system, what are the advantages of using it ?

[thundead]

Well it is a uhf system freq wise and it is still being tested.
The adv would be it is legal in the uk, cheapee than an ezUhf and has telemetry built in.

Apparently someone trsted it up to 3km.

I went 1183m and my sig was rock solid

So you'll be basically limited by your video range (that's if you are flying legal haha)

Plus being UHF it is a LOT friendlier for handling situations where you 'may' end up with your plane accidentally going behind something like a group of trees, a haystack, a building..... with 2.4 you can almost guarantee the radio going into failsafe.

Haha happened to me a few times. Another adv I see is you can have 2.4 for video which should be better than 5.8. Anyway.

That's the only advantage I could think of, however, if the range is only 3km then 5.8 will do fine anyway, the last thing you want is video range exceeding rc range isn't it ?

Interestingly I have the FY21AP autopilot on one of my planes and it is quite a laugh trying to fly it out of LOS range using my 2.4 GHz FrSky moduled Futaba transmitter as I have the failsafe nicely set up for RTL.

Its like having it on an elastic band....

I fly directly away, loose 2.4 signal, failsafes to RTL and turns and heads back, I get control back, turn round to fly away, loose 2.4 signal etc etc (you get the picture)

If flying FPV on 5.8 (as I have) and you are fortunate enough to still have good 5.8 video (through good antenna selection and luck) its quite amusing having the plane suddenly turn round when you were enjoying flying away !

I've got the frsky 2.4 aswell but never did a range test on it. I was on 5.8 when I did the lrs range test video. Fy1ap in there aswell haha. Im currently messing with my shiny new ardupilot mega and I can say it beats fy's butt. No more vibration problems. I had an unbalanced prop in my fy21 plane and at full throttle the ailerons would go mad. Found out that a good way to dampen some of the vibr is to mount the fy using velcro haha.
