Tandem Helicopter Setup for Vario Chinook 2-2 servo
June 01, 2026 12:31PM
Hi,

I have the Pro App, which allows tandem helicopter setup, but it only supports 3-servo and 4-servo swashplate configurations for each rotor.

My helicopter is a 2-servo/2-servo setup, similar to a Vario Chinook CH-47. How can I configure this type of tandem helicopter in the app?

Thank you for your help.

Just set as 4 servos to get aileron and collective right on the now connected 2 servos.
In the panel is also a parameter as mixer for elevator moved with cyclic or differential collective for each swash. This must be dialed in to get teh differential collective working.
