Hitec 5805 problem

[deephis46]

Hello, I have a Hitec 5805 servo for steering. The gears are 4pl, R2104GF, cc bec, a nanotech 7,4v lipo 1000mah. First time I'm using it, it works well. Until on Sunday two days ago, I had the problem.
If I turn steering wheel slowly the servo works well but when I gave fast turn on steering wheel the servo can't move. On the throttle it works fine, I'm using a 7955 on it. I have tried using HPP-21 Hitec Programmable Servo and have the same result.
Anyone know where is the problem?

It could be the receiver have you tried switching the servos wires to see if it does the same thing on the throttle?

 

[deephis46]

I have tried on all channel but I got the same as like on channel 2, still move very slowly..

 

[rcspeedmart]

even if you use another servo on the same channel that you are having problems does it do the same thing?

 

[deephis46]

no, with another servo works very well

 

[OuttaLuck]

no, with another servo works very well

Well sounds like the servo has had its day

my 5805 actually new, just about 2 weeks old

so how long Hitec give the guarantee for servos? I think I'm going to send it to my LHS...

if you have a 6 volt battery pack try that without the bec. the bec puts out a max of 5 amps, that servo itself could draw that. hitec also recommends direct powering it.

sounds like dodgy servos dude, if under a year old then still under guarantee

unfortunately i don't have rx battery, so i can't try it. yes, the manual says that too, i have to power straight to the servo. but i don't know first time i'm using it, it works really fine with bec...cc bec rated max 10Amp, i think it should be fine

my servo only 2 weeks old.
i just called my LHS they gave me the guarantee, maybe tomorrow i send it to them for replacement.


FYI, i have tried with DX3R and got the same

Thats the electronics world though. I honestly don't remember how many servos, esc's or recievers Ive had be dead right out of the box or within a very short amount of time. Hopefully you can get it replaced easy, Ive had them replace a few without any trouble. Good luck!

 

[rcspeedmart]

Yes servo is gone hitec will replace it.

 

[deephis46]

Before i sent it to my LHS i'm still trying what is going on but no result. Then i called them today, they said bring it here and i get free replacement:cup-1:.
Got the replacement but they don't know too what is happened with my servo.

Thanks to you all guys that had gave me enlightment and my LHS and Hitec

This type of servo can't use a BEC system. It runs on 6 volts direct from the receiver. If the receiver is BEC then use the supplied ""y" harness and bypass the BEC. This servo requires at least 1200 mah. I use 5000 MAh 6 volts and it works fine.

CC BEC rated max 10 Amps though. Maybe my BEC had failed. Actually the BEC is only just for a moment and I'm still searching for rx battery. I found smaller mah one it's about 1600mah, it looks like use for 1/8 truck. Does it capable to powering 7955 and 5805 servos?

BTW, how long did you get using a 5000 mah 6v?

Most BEC systems are on 2 channel receivers and are rated 3 amp max. The HS 805 servo needs more than that. That's why they supply a "y" harness to bypass the system. With FM and 2.4 systems there should be no problems. I run 2 HS 805 servos direct to my receivers and have hrs of runtime.
