It appears that the links on the head are too short, because proper pitch cannot be attained at there current link( not even close) Do i need to increase the lengh of the 3 swasplate rods, so that the swashplate will set higher on the shaft---any help would be appriectied ( sp wrong)

you will have to do one or the other. Either lengthen the swash links or build longer pitch rods.It may depend on your clearance issues at the head... and how you intend to phase it.

You know I had that same problem on one of my birds, but I just fixed it today by drilling out the four J arms from 2mm to 2.5 and retapping them to 3mm. I can get you pictures and the length of the 3mm rods I used in the morning, if you want to see what the set up looks like. I don't have a three blade head on my sky fox but I have a four blade head.

Yup, Glassman has the right fix if you choose to lengthen the J arm links. Because those 2mm bolts are cheesball small I just lengthened the servo to swash links on my rex600. The swash sits a little high, but you're not flying 3D, so you don't need the extra collective travel.

rc aerdyne 4 blade head
Donny Boyette: Here are the pictures and the rods I used. They are 40mm long but it will depend what length main shaft you are using on your bird. I hope this helps you, my set up is for the sky fox mechanics to go in a Bell412.I took the pictures with flash and without to be sure I would have to post them one time, sorry if there is two many.

Thanks guys, those pictures will help alot--@ Glassman, once you drilled the holes to 2.5, what did you use to tap them to 3.0????

I used a 3x5 metric tap and the 40mm screws I used a nut on the bottom of the J to lock it in place. you will also have to open up the Ball link ends to 3mm also using the same tap. Don't forget to lube the tap when threading the J arms.
