Strange Protos problems today - either RX, BESC or servo.

[Stanley Speel]

Hi

Two strange things happened with my protos today - not sure if they are related.

The first one was the most worrying - a couple of times the heli would 'stick' and the correction made on the TX was delayed. For example I'd do a flip and the heli would not be level, and it would not react to a correction until after about 2 seconds after. most likely suspects are:

1)elevator servo - has one notchy tooth and sometimes jams when moving by hand
2)BEC - It's a cheap HW 60A platinum pro ESC
3)RX - was a brand new AR6200 but it came in a clear packet? No brownout shown.

The second I'm not that concerned about, but when inverted hovering the ESC gave up for a couple of seconds but then luckily started up again.

I flew a few packs after this happened and everything seemed fine, although the delay issue recurred a couple of times...

Has anyone got any ideas etc?

thanks

Stanley

Think you need to change the servo gears or replace that elevator servo before doing anything else.....

bad solder joint somewhere?

How can u not be concerned at the esc giving up for a couple of seconds whilst inverted !!! Lol
Sounds like esc related and I'd start with connections and solder joints

Make sure your Heli is earthed the protos has static issues with that big belt.

I've just had a look at the event log on the Vbar - the only concerning thing is quite a few "Extreme Vibration warnings" - I have the black sensor.

I'm guessing this means that it must be either servo or static related as the Vbar would realise if the BEC was dropping voltage?

I'm not that worried about the ESC cutting off because its only happened once and the worst that can happen is a non-powered crash
