Hi

I have a Futaba 3PK with HRS and want to use the 9451 servo and a Sanwa ERG-VX. The Sanwa servo looks like its loosing its position when i move the steering too quick.

Does anybody know if this is a known problem?

Cheers

Ziggy 12345, put your transmitter in ppm mode (standard FM) and see if it does the same thing. I believe if you run your 3PK in HRS mode w/o a digital servo that will happen. Hope that helps.

BTW, switch modes in menu 3, under "system". pg 16 in the manual.

Do i need to swap receivers? I have the HRS receiver so i wont work at all will it?

Your HRS receiver will still work in FM mode, give it a try.

ERG-VX is not a digital servo, dont use with the HRS receiver.

Ziggy, i think tl2111 is right Futaba HRS receiver will not work with a non digital servo better swap either your servo or your receiver

non digital servos have a slower frame rate & can literally get fried when used with an HRS reciever

Ok ill send it back to the supplier. He can send me a digital one as replacement. Whats the best digital servo for buggy steering?

if you wanted to stick with Futaba i've had good service from the S9451 but there's been news of a new updated S9351 which has more torque & an alloy casing

The Sanwa ERG-VX is a digital servo. It just doesnt work with Futaba HRS system. Does anybody know why?

i'm trying to find a definitive answer to this at the mo but THIS says they aint

So not digital then. That clears it up. I posted it back to HK today
