Default gyro/servo????????

Is anyone using the Futaba 401gyro/9254servo on 6 volts. On the info that came with the unit it says 4.8 volts only and I would like to use it on 6 volts if I can without frying it.

Stick with regulated voltage on that servo. I have had one fry and I know of 2 others that have had an issue with it on 6V.

The GY401 & 9254 must be run on 4.8v, or else the magic smoke escapes

Yea, it sux, but thats the way it is. I am not sure if anyine makes a gyro/servo rated for 6V. The upside is that the GY401/9254 is a very good combo unless your into hard 3D.

I have given up on the very short life of the 9254 when used on the boom of a nitro ship.
I am now using the 401/HiTec 6965.
This combo is perfectly happy at 6V, the nitro exhaust residue has no effect on the HiTec servo, and I can not tell a difference in performance once set up correctly.

6v doesn't bother the gyro. If its 6v regulated you can run a step down to the tail servo and it will be fine.

I prefer canopy mounted servos anyways. Most people that cook 54's are going old school and turning the gain up till it wags then backing down a hair.

Thanks for the info guys. I did order a voltage step down (Align) so I can use the futaba 9254 and installed a hitec 6965 to use till it gets here. The problems with the 9254 failing is that only when mounted on the tail boom and not when mounted on the frame.

The failure mode of oil getting inside the servo only happens on the boom.
The 9254 is still not a real long lived servo compared to others.
