I sure could use some help on the correct control rod lengths for the V3 model of the hdx 450. I guess finless built a v1? The online manual is confusing and at times contradictory.
Thanks for your help!

The finless video measurements worked pretty close for me , I too have the hdx 450 v3, currently I fly with these lengths ...with the swashplate at 10mm

1st linkage rod from the servo horn to the swash is at 50mm

2nd linkage rod from the swash plate to the lever arm 48mm

3rd linkage rod flybar cage to the mixing arm is 29mm

and the blade grip rods are 25mm close tight and adjusted as needed for tracking purposes.

Also if you do decide to buy the align linkage rods package I reccommend buying the XL version, The other version cde , etc rods are two short and you wont have enough threads to secure linkages to the length you need, Hope that helps .

Does giving rod lengths mean anything if you don't specify the type of servos you are using. I say this because aren't the position of dead center servo horn different depending on the type of servo you use. For instance my JR DS285s appear smaller than the HS55s I've used in the past, wouldn't the rod lengths be affected by that?
