General Align 450DFC Main Rotor Head Upgrade

[ramosja]

Hello, I have a 450 sport v2 and bought the Align 450DFC Main Rotor Head Upgrade . While building the head I noticed that link rods sizes specified on the manual where too long after I installed them on the heli. All servos centered the blades came up at about 12 degrees pitch. For example rudder size is 37mm, pitch 43mm and elevator 31mm.

Not sure if the manual has them wrong, does anyone had experience with this upgrade?

Thanks,

Javier

The DFC head should have come with it's own links. And because of the shorter main shaft, you will have to make the links shorter as well. Is there any way you can post a picture or video of your issues? I may be missing something. but, if you download the 450 Pro DFC manual, it should have the correct lengths in it for the DFC head.

I did merge your other thread into this one. Also, I"m going to be moving this into the heli section since we don't allow questions in the lounge.

Okay, I see the issue (a picture is worth a thousand words lol). YOu need to substantially shorten your swash links. You may ahve to order new ones in all honesty.

thanks again, I had already made new rods, but then its certain the there is an error on the manual.

Yeah, I don't know what is going on there. How did you measure them? Exactly as in the manual?

hmmm ... my 600 DFC kit did not need new links. worked perfect out of the box .... new swash, new shaft and DFC arms and head and DFC blade grips. just clipped off and clipped on.... Come to think of it ... I did have to lower the swash by 2 turns to get it to work but nothing major

Same here. Everything was "plug and play"
