120 deg. CCPM users: servo mounting?

[ShakyHands]

If you are using 120 degrees on the swashplate, how do you have the servos/links mounted. Obviously, you can't have the two front links run exacly vertical, so they cause a little problems with the geometry of the swash.

Are there any problems with the non-vertical links? I understand that some radio re-programming will be nessesary.

I did see one fellow who mounts his servos on aluminum mounts to correct this, but that adds weight.

Unless your radio does 90 degree you are stuck with the 120, Now you can make the little brackets and add a tiny bit of weight. Or just stay at the 120 with the control rod on a bit of an angle, Hardly makes a bit of diff, in the geometery. As long as all three servos come up and the pitch changes and your flying, your all set. They do make an on board mixer and I dont know to much about it. But this rasies another question I dont have the answer for. Can you use the mixer with a 120 degree radio to get 90 degree. I dont know, maybe someone else here does. But all in all I fly 120 with a JR652 and a bit of angle in my control rods no biggie and it handles like a dream, But I dont fly any 3D stuff either.

The modification for the 120CCPM is shown in http://www.dokidoki.ne.jp/home2/tohrus/

The servo mount plates are newly made to establish the exact 120deg location.

Take a look at my photos and set-up information at http://www.bernard.u-net.com/eco8/
I have had no problem with the offset links, just make sure the swash plate stays parallel when you move the collective up and down.
