Silly question ?

[bred403]

i am newbie in this hobby and wanted to know what is the purpose of Travel Adjust in DX7?.currently setting up 450 and setting up CCpm learning from bob's videos.and wanted to know during CCPM using bubble on the fly bar is he adjusting through Subtrim or thru the Travel Adjustment.

which one do i need to use to balance the swashplate?

Sub-trim to get the servo arms at 90deg for centre stick, TrvAdj to sort out CCPM interactions as per Bob's video.

i think travel adjust means to decide travel range for servos. and sub trim is to level swash.

[kgfly]

For the swash servos, use sub-trim to get the arms at 90deg, adjust linkage lengths from servos to swash to level the swash and get zero degrees pitch at mid-stick, adjust the linkages from the swash up to get the head setup rigth at mid-stick and then if needed, use travel-adj to remove CCPM interactions at high and low stick positions.

Subtrim - adjust the center or neutral position of the servo.

Travel Adjust - adjusts the full throw end points of the servo or how far it moves from center. And it can adjust each direction separately.
