thUndeadMod v3.4 - openLRS S**T just got real :)

Splashy u got any problems with the latest version ?

[Splashy]

Hmm something is seriously wrong somewhere in your setup. what antennas did you use ?

I'll do a range test tomorrow with the the latest fw and see how it goes.

Ok guys just back from a practice and a range test

Lost control of the plane at about 300m (flew beautifully inside 300 might I add), and inside of 300m the motor kept cutting out about every 30-40 secs and then starting up again after about 1 sec.......

after recovering plane (didn't crash thankfully just landed softly again) I gave my spotter the Tx and drove off about 600-700m...and nothing.....everything still powered up and can still get Vtx picture but no signal (red light on Rx).

This is on the NEW Rx I got today!

came back cause I was starving  :(

The antennas are exquisitely handmade antennas (like yours) and are 459 Mhz ones.

No .. but have not done a real range test yet. I am just taking the RSSI and putting it straight into the RVOSD. As you know, if there any glitches then it pops into RTH mode. On the previous version it was glitching, on this version the RSSI looks very solid. If you switch off the TX then RSSI drops to 0.

The PPM is working perfectly on pin 1 and connecting 2 and 4 does correctly turn it into PPM mode.

I will get my daughter to run over the field next door holding my Zephyr II. That should be good for a 1.5 km range test. I'll even put the goggles on so I can direct her from the comfort of the patio (and keep an eye on the RSSI).

Trev

I lost total control of the plane for that second...every 30 seconds or so...then nothing but the power was still on at the plane....I have the standard kit for the ez*2 ESC and its a 20A

The Rx is being powered from a 8.5amp BEC and powering 4 micro servos

I still keep picture and all displays from the EZOSD mate

it just seems the further away the plane gets the less control I have.....but full picture and display from OSD

[Cat695]

I'll stick it in my quadcopter tomorrow and see if I get any problems with that (I can see the rotors better at a distance)

And I'll stick the other Rx in my twinstar

Least that we can either blame the easystar or not......

[papa_lazerous]

Cat695 is it possible there is some interference based on where you are in the country? Salisbury plane and all the military activities are there any large antennas nearby?

[Cat695]

I thought that but our radio's don't constantly broadcast (DF hazzard) and it would only be random cut outs as someone pressed the pressel and stayed on the net talking/sending data so I reckon because I only get a 1 second cut out and its pretty much at 30 sec intervals its not that mate.

[Splashy]

But you did say that the motor cut out .. Do you think that this was due to a loss of comms causing the failsafe throttle to be set?  When you say loss of control does this mean that you did not have any control over the plane during this cut out.

Don't suppose you could see what the RSSI did during this cut out .. obviously this would let you know whether it was down to the RX.

[Cat695]

I don't have RSSI connected mate.....I only know what I'm getting when I connect a multimeter, hence why I just fly rather than bench test, that way I know I'm getting and giving real world facts to you experts rather than lab conditions. (i'm no electronics expert by any stretch).

I think its a loss of comms.....like its resetting itself....it lasts for a second maybe 2 max...and I lose everything...literally every 30 secs or so then past 300m nothing.

I will fit it to my quad tomorrow and just hover....walk away and see what happens...if thats fine then I will look more towards the ezstar being a sh*t build.....also have a twinstar I can test on to...

BUT Ian had the same thing happen to him today,,,but he restarted and it worked again.

[papa_lazerous]

I think I'd hold back on putting it on a quad mate, if you get fail safe with the quad it might not end as well as it did with your plane.

[Cat695]

also could it be my PPM output from my DX6i?? if I remember rightly when I tested it from the trainer port (how its connected to the UHF) many moons ago it was about 2.9

[Cat695]

I think I'd hold back on putting it on a quad mate, if you get fail safe with the quad it might not end as well as it did with your plane.

WHat I'll do is set the quad down....walk away and then arm it (a naza has to be armed before it will fly) so the props will spin.......if after 300m they don't spin (i'll take binos) then I know its the Tx and RX and not the easystar

[Cat695]

Ok I'm back as been searching the net......have you guys seen this antenna for UHF (has been used on openLRS) You antenna'perts might try out out!!

Build IBCrazy's 433MHz Turnstile antenna for FPV

[Coyote]

I built one and even on my 60" wing it was far too large. If you think about it the uhf range records are done with mono or dipole antennas, all to silly ranges. So I don't see its practicality at all imo
