Receiver or ecs ?

[glennwil]

Powered up my 450 pro Futaba 6008 receiver,DS410m servos,DS520 tail servo stock esc blx35 and I noticed that the servos chattered and stopped working looking at the receiver I could see that the light on rec was changing from red to green (blinking) so I disconnected the servos and plugged in only the esc and the receiver light became solid untill I plugged in servos and then it started blinking.I thought it was the esc so I plugged in a old Eflite 40 amp esc and it did the same thing,so I pulgged in a sanyo 4.8v 600 mah flight pack in and it got rock solid and the servos worked normally changed back to either esc and light started blinking and the servos were erratic.Help!

sounds like your plugging the esc in backward
it will power up but everything will be silly
and if left you will eventually burn up the receiver
after a little time you'll notice the receiver getting warm probably
make sure your pluging in the esc or bec in the correct direction
if you are then it is the esc/bec that is bad

Sense the orignal post I changed to another receiver 6008 also and it acted the same way so I can rule out the receiver and think about the current drain the servos is putting on the esc,I connected 4 DS5065"s to the receiver same esc and it is rock solid .

Have you checked if the servos move freely?

[glennwil]

No,I haven't checked that but I would plug in one servo check for blinking disconnect it and move to another and when I plugged in any one sevo it would start to blink but not with the Hitec servos,this heli was flying great last time out !

sounds like you have a dead servo there...plug one servo in at a time untill the dead one can be found
i also had this with 410m servos before...no crash, it just stopped working and caused all other servos to glitch.

+1...It definitely sounds like one of the servos is causing an issue. Three DS410m's should run fine on the ESC especially on the bench....

Is the ESC getting hot when you do this?

[glennwil]

When I plug in any of the individual servos in it causes the led to blink like it has lost its signal this is one at a time, and with any one single servo plugged in and it don't matter which one it is ?

I would temporarily use my known good bench BEC.

[glennwil]

In the morning I'll take the esc off my 500 and check it out and hopefully it will confirm the esc is where the problem is . Thanks for the help!

[chrismechanic]

hmm..it cant be all the servos...try the rx swap...

Found the cause it was like chrismechanic had suggested had a bad cyclic servo though would change to hitec 5065mg's I have 3 of those would that be a good swap?
