JR DS3500G vs JR DS3517

[LaurenceGough]

Hey guys,

I've heard the JR DS3400G tail servo has been discontinued... (darn...)

Can the JR DS3500G be ran on 6V? (I've heard that this is the replacement for the 3400G which I wanted)

Or would the JR DS3517 be a better choice than the DS3500G still?

I need to run it at 6V.

Thanks very much.

I'm using the 3500g on the tail of my Protos with a CSM720 gyro and it works very well. I'm running 6V out of the BEC but I'm using an Align 5.1V step-down in the servo line. Looking on the JR US site the 3400 has figures for 4.8v and 6v in the specs but the 3500g only give one set of figures without quoting input voltage so I'd say 6v is out.

I looked into this but didn't post as I couldn't find anything concrete...

I'd agree with Steve but I'd also add that I ran my 3500G's on cyclic for ages on 5.5v until my Align ESC decided it was time for a fire

On the tail a single servo is going to get a harder life depending on your flying. Possibly worth a call to JR(McGregors) but don't hold your breath as they gave me a load of old crap about DS3500's not being any good for cyclic duty but I'm convinced this was to help out the con men at Robbe UK so they could cover up the fact the Align ESC is not fit for purpose as they have still avoided paying for my replacement servos even though Robbe replaced the POS ESC

Got the DS3500G as you know m8, but not flown it yet as still waiting for the mounts from RC Tek.

I agree, just wanted to know if anyone was running it on 6V with no problems.
Good to hear that it works for you on 5.1 with a larger heli with no problems though!

Hey ya mate, funny eh, I've got the mounts but you've got the servo, wanna swap?

Lemme know when you do fly it ASAP! You going to run it at 6V or 4.8 etc?


Thanks everyone very much for the help!

This is the last time I'm going to say this honest but...

The 4.8/6.0v question really dates back to whether you are using a 4 cell or 5 cell NiCd or NiMh Rx pack and has no real bearing on regulated 4.8/5.1/5.3/5.5/5.8/6.0v

If you run at a higher voltage the servo will be faster and it could have a shorter life but it is unlikely to kill it dead the minute you plug it in...honest

Ok, I'm using a regulated 6V switching BEC

Well it works fine on 5.1V so no need to run it at 6V, I just don't want to add to complication/wiring/weaklinks/heat buildup?/efficiency loss? by running a step down.

[Smoothound]

The main problem was the fact that a 5 cell pack was around 7+ volts hot off the charger, it drops quickly from here once loaded but when you plug in/switch on it could be over 7.0v
