Will a 6 volt pack work with the heli gyro? it's a 401 gyro a buddy has, he switched to a 6 volt pack and now the tail wags a lot...

They do not suggest it, you really should use a votage reulator.

mrhook is right.

Use a regulator, mine work great on 6.0 volts regulated. If the tail is wagging a lot turn down the gain. With carbon tail blades, and a 19mm arm I'm running about 45% gain on a Rap 50V1 with an Airtronics radio.

6V on just digital rudder servo

The gyro can handle the voltage, Futaba claims the digital servo cannot. I run a reg. on just the servo. Radio South can fix you up with a good one, and can wire it for you so that you can just 'plug and play'.

Unregulated 6 volt packs come off of the charger hot at around 7.2 volts. That voltage will fry your servos. Regulated 6 volts is safe. I've been using it for over a year and servos are fine.

Reset your gyro setup and center. Then trim it in a rate mode hover, using with the ball link to eliminate almost all drift in rate mode. Do not use any rudder trim at all. It must remain at exactly 0 in all flight modes. Then switch to the heading hold mode, and turn the gain down some until it just starts letting go a little punching the collective. Then increase the heading hold gain a point at a time, until it holds without question.

The servo moves faster on 6 volts, and will require a lower gain setting then you have typically used in many cases. If you have the correct servo arm length, and gain setting, it will work fine for you on 6 volts.

Adjust the gain in the heading hold mode with test flights, after it has been hover trimed in the rate mode, using the rudder ball link on the servo to hold solid in a hover with no drift while in rate mode only. Then add just one or two extra points of gain only. This way you won't cook the servo with excessive gain numbers, after the gain is set to hold well. And the wag now should be non existant.
