Fried servo's on the side.

[david h]

Dear all,

I recently had a reciever die on me.. I was not impressed. It was second hand and 10 years old, so I suppose I could'nt really fault it. A futaba one, nice,

A couple of months ago I bought a ALIGN RC RX6 reciever. Really small 6 channel. I deal for small Elec helis's. When my reciever dies I thought ,excellent this reciever will do well, it's small and light and willfit ideally. So I pulled out the old reciever and started hooking things up.

This is where the problems started, I run 2 x 6V 1.3 Ah Sealed Lead acid battery in series to a pump. One battery is for the RC gear. Now with my old Futaba reciever I never had a problem, it ran off the 6 v fine. However the little ALIGN reciever fried the two servos I has hooked up to it? What is with that? The receivers fine but it smoked my two hitec servo;s not happy....

I am hopeless with electronics as you can guess but I don't remember seeing anything on the Align website saying that the reciever could'nt take beyond the regular 4.8v?

Can anybody explain this?

regards,

David Hughes.

Hi mate,
will call you soon sorry not been in touch for a while.

I suspect the Rx might not be Ok with the 6volts, and in the case of the SLA freshly charge can be as much as 6.9 volts. Most Servos can take the voltage Ok through a Rx with a BEC but maybe if there was no BEC on the Rx maybe you cooked them. Also maybe - the servo leads when attached to this Rx connected incorrectly and caused a polarity problem for the servos?

Am guessing but never heard of what you describe as happening before.

Best

John

Hi john

Thanks john,

I've been meaning to ring you for a while. Life gets in the way. Hey did you see my boats in the Article on the Canberra Sub regatta from latest issue SCR?

Come on People. Please reply!!!!!

I know this is quite

I know this is quite silly but just in case (it happened to me before): Have you connected the servos using the proper polarity on the receiver? I've fried a servo (smoke and so...) in the past when trying to connect it to an Airtronics receiver while the servo had the Futaba wiring.

From an online photo I can see that the connectors polarity in your receiver (- + signal) is compatible with hitec or futaba servos' wiring but also notice that it has nothing to stop an accidental wrong connection (i.e. signal to the negative)

dodgy servo's

DEar all,

I hooked up the RX again to some different servo's (Cheap premium and GWS) and it WORKED! Could'nt believe it. Earlier it fried my Hitec HS-322's but now it works fine....

I'm totally puzzled yet relieved. I did'nt want to fork out $70 for a Hitec RX.

this little Align rx is proving to be a good buy.
