Thanks for the responses MM & MDS.

It has been about three weeks since I received my DX7/AR6100/3xDS285 combo.

Since then I have been learning how to set up and program a CCPM heli from the ground up.

I have replaced all the stock electricals except the two motors and the 3 in 1 board.
The install went very smoothly. Servos dropped right in. All systems working properly!

The only issue I had was that the [JR] servo's wire is shorter than the stock ones.
I was able to route the wires the way I wanted to, but just barely.
Another inch or two of wire would be great (but that reduces profit margins).

The only mistake I made (initially) was to set up the servo centering and swashplate level & travel centering
with the throttle/collective stick at 0% instead of 50%.

While correcting this I decided to convert the three swash control links at the servo horns to ball links.
I would recommend this very cheap, very easy mod. to all!

Before this mod. I could put my finger on the anti-rotation shaft, at the rear of the swash, and move it around about +/- 1/16 of an inch in all directions.... now, it's darn near rock solid!

To do it I bought:
Dubro ball links; some threaded rod; and a set of spare (HeliMax) seesaw - to - blade grip links (for proper fit to swash).
I mounted the Dubro balls to the swashplate servo horns... on one end of the treaded rod is the Dubro ball socket... and on the other is one of the spare stock links (to connect to swashplate).

It really wasn't difficult to convert the links and learning the DX7 is really easy.
I am still tweaking the pit. & thro. curves but it really is more fun now with the programming flexibility.

Now I have a GY401 awaiting install and can't wait to add that experience to my "toolkit" as well!
