beastx

[mr magoo]

Hi guy wondering if anyone has had a beastx reset in mid flight.
I was taking a turn and the beastx done it up and down looked like the smallest tic tic then down it went.

on the bench all was fine then the beastx went off

[crash-test-tomo]

I did once on a 450, a few years ago!
I lost all control then the pitch started to jump each way, it never got chance to fully reset as the motor died literally a split second later.. Blades stopped and down it came.
Turned out my esc had failed and after I replaced it I never had the problem again! No fault at all of the beastx

I've never had a problem with beastx , at one point I had 7 heli's fitted with them , now got some on spirit

[trex flyer]

I have four helis all fitted with Beastx, 3 are in scale fuselages one is a trex550dfc.
One of the scale helis had a slow creep on the elevator, in the hover it would either nose forward or roll backwards, very slowly, but you could always override it with stick input.
Even on the bench it would initialise, and if nothing was touched on the transmitter, after a while the swash would tilt either forwards or backwards.
Again though you could always level the swash with a stick input.
I swapped the Beastx with the one from my trex550 because I needed the scale heli for a fly-in.
I put the 'faulty' Beastx in my 550 and obviously redone all the settings and it hasn't done it since, this was back in August.
I did some Googling on strange Beastx behaviour, one YouTube video shows the same thing mine did but only with excessive heat applied via a hairdryer ??
The cyclic creep I've seen doesn't appear to be uncommon, various YouTube videos showing the same problem.
All mine are powered via the esc.
Are yours the same or powered by separate battery ?
Is it possible your Beastx power supply failed ?

its a brand new trex 550x all was fine on the first four flights.

checked all the wiring after the crash all was fine, I then repowered it back up to check for servo damage, all was fine, then it just switch off

I'm using the main flight battery to power beastx and receiver

[waveydavey]

Sounds like low voltage and failsafe. The BeastX doesn't like cold weather and has been known not to initialise in very cold weather but not reset that I've ever heard of.

Edit : Not failsafe but brown out

Try running a separate supply to it, they're 2S capable I believe and see if it happens again

hi Magoo , Davie smith was running his goblin 700 from a 2s battery & it constantly lost power to the motor ( not servos)
i gave him a castle pro Bec to fit & problem was gone

[mr magoo]

the lipo was fully charged had 76% after the crash, the beastx was fully initialised before take off, it re-initialised in midair

[waveydavey]

Just because a LiPo is fully charged doesn't mean to say it's delivering what the electronics need and that a voltage drop brown out, not failsafe as I put earlier didn't occur. Have you tried putting another power source on the beastX only. Stick a 2S on it if you're servos etc can handle it and in the comfort of your own living room twiddle the sticks and see if you get any brown outs.

What BEC is it?

its the align BL100A ( hobbywing )which has built in bec set to 8.4v

It does sound like a low voltage issue triggering a reset. I've never had a problem with BeastX, but I do run an Optipower BEC guard on my G380 to protect against potential brownouts. Might be something to consider, they are not that expensive. You could go one step further and install an Ultra-Guard with back-up battery. I presume you have looked for an obvious loose connection by jiggling the wires etc when powered?

[hellraiser]

I run several Beast X units & have never had this issue, however I power mine directly from a 2S & have run two power leads into the Beast X, hopefully to cover a bad connection or cable, but also to make sure there is enough sparks getting to the Beast X to power all the servos etc.

[mr magoo]

yep I did checked the wiring all was fine all plugs in correctly. at one point I had it powered up and then the beastx went off. is this a common thing with running the flight lipo to also run servo's and beastx

I only run micro (and 1 mini tail servo) with BeastX with only a flight battery, so not sure if it's common to run larger servos without an additional power supply. But if it reset while just sitting on the bench then it doesn't sound like a servo power overload - unless one of your servos is faulty and drawing excessive current. I've heard of faulty servos causing power issues like this, so worth checking. Maybe try powering up without connecting any servos and see if you can replicate the reset problem to rule out the servos? Maybe also worth trying to power it off an alternative port on BeastX? There are several ports you can use for powering it. As someone else mentioned, some people run 2 power supplies for redundancy and increased current capacity.
