How to set up a dsx6 for a helicopter?

• A servo is a mechanism, usually a motor of some sort, that drives another mechanism. On a passenger aeroplane, for example, the control surfaces are too difficult for the pilot to operate because there is so much wind pressure against them, so they use hydraulic servos to move the elevator, flaps etc.
• On a car, the drive by wire throttle control is a servo, which is electronically controlled by the computer, depending on the throttle position under the driver's foot.
• In effect, the power steering ram on a car is also a servo, which is powered by the p/s pump, and controlled by the valves in the steering column.
• On a smaller scale, the air conditioner has servos that open and close the relevant air duct flaps when the dashboard controls are shifted to control the flow of air in the car. Please note that on older cars, and some new ones, these flaps are not controlled by servos but by cables.
• The remote controlled central locking on a car has servos in the doors that open and close the door locks when the remote button is pressed. On some cars these door lock servos are small electric motors, on others they use vacuum operated pistons, also called servos.
• Hope this answers your question!

If your talking about 2 servos per aileron (4 total) I think you'll have to use 2 "y" connecters and sync the mechanically. I don't think it has provisions for 4 aileron servos. For 2 you adjust them in sub trim.

Check all wires to the servos in the copper. They do come loose and get croted, clean your connection and try that, worst case, you may have to replace the servo. Must hobby stores have them.
I hope this helps you

They sale servo mixers for things like this. Google servo mixers.

The swash plate is broken or the servo gear set is binding.
Set the trims again.
Reverse the trims on the transmitter.
Pull the servo that controls the swash plate and re locate the arm.

I'm afraid that the transmission's O/D solenoid malfunctioning or kick down cable may be misadjusted if so equipped.

looking at a rebuilt transmission if you plan to keep the Caravan.

Or, alternatively, could get a low mileage transmission from a salvage yard and have it installed.

Servos/Accumulators The servos are hydraulic pistons and cylinders. They resemble the hydraulic actuators used on many other machines, such as bulldozers. Hydraulic fluid enters the cylinder, under pressure, and forces the piston to move to engage the band or clutches.
Servo operation

The accumulators are used to cushion the engagement of the servos. The transmission fluid must pass through the accumulator on the way to the servo. The accumulator housing contains a thin piston, which is sprung away from the discharge passage of the accumulator. When fluid passes through the accumulator on the way to the servo, it must move the piston against spring pressure, and this action smoothes out the action of the servo.
Hydraulic Control System The hydraulic pressure used to operate the servos comes from the main transmission oil pump. This fluid is channeled to the various servos through the shift valves. There is generally a manual shift valve, which is operated by the transmission selector lever, and a shift valve for each up shift the transmission provides.
Most automatic transmissions are electronically controlled; electrical solenoids are used to control the hydraulic fluid. The shift solenoids are regulated by an electronic control module. Shift timing is regulated through sensor feedback information provided to the electronic controller.
On older transmissions there are two pressures that control the shift valves. One is the governor pressure which is affected by vehicle speed. The other is the modulator pressure which is affected by intake manifold vacuum or throttle position. Governor pressure rises with an increase in vehicle speed, and modulator pressure rises as the throttle is opened wider. By responding to these two pressures, the shift valves cause the up shift points to be delayed with increased throttle opening to make the best use of the engine's power output.
Older transmissions also make use of an auxiliary circuit for downshifting. This circuit may be actuated by the throttle linkage, vacuum that actuates the modulator, or by a cable or solenoid. It applies pressure to the downshift surface on the shift valve or valves.
The transmission modulator also governs the line pressure, used to actuate the servos. In this way, the clutches and bands will be actuated with a force matching the torque output of the engine.

so whats your problem, 1 servo 90 degree is right setting, use the software for your mixing

turn your servos around

Try setting gain on Gyro (use small plastic screwdriver) to a straight up and down position.

Set Gyro setting in Transmitter to 75%. NOTE: before turning on helicopter, be sure to center all adjustments on transmitter

Side switch on GYRO to DS and make sure the servo is moving in correct direction. If not. reverse direction with switch on side of Gyro. You may need to reverse the controller of Rudder in settings on transmitter.

This worked for me on my Blade and using the same Gyro on a self build 450 heli.

Good luck!
