To get this ball link positions, AND to maximize up/down movement of the wash plate, the longer part of the push pull arm (yellow line) is used:



And to my surprise, the mounting (arrow) to get it spot on was exactly in the middle of the frame as shown above.

Another view, where the mounting screws are placed in the middle - directly above the original bearing mounts (arrow) of the now un-used elevator see-saw:



Placing the push-pull in this location also clears it comfortably away from the rotating tail drive (yellow line).

And therefore, this is the full servo arm and ball link set up to the CCPM swash plate:



I found the third hole on the HS 65 servo arm (arrow) to be the best position to maximize swash plate movement and get +10 / -10 pitch.

The only other mod required is the mounting to the canopy and cutting out a small portion of the canopy to cater for the push-pull link movement:

The canopy mounting (red arrows) is moved down to an existing aluminum spacer (black arrow). The mounts were basically just screwed on:



It still gave good support to the canopy with no issues in flight. The nut and bolt at the bottom of the canopy remains as previously:

Well, THATS IT!.

CCPM is the last major mod for this heli.
And after flying with CCPM the past 1 week, I can't see myself ever going back to mechanical mixing. There's just no comparison. Handling, pitch control (e.i. altitude control), predictability during flight - are all just amazing with the CCPM set up.

I probably even lost a few precious grams due to the conversion.

WORTH EVERY MINUTE (and $$) I SPENT ON IT!!!

Good luck and Happy flying! :mrgreen:

Well... its been a while.
I've been bashing the CCPM set up quite a bit. Still love the stability. I did encounter one issue with the set up though. On one of my looping flights, I suddenly lost control of the heli. It was still flyable but barely!
When it got down (no crash!), this is what I found:


An over extension of Pitch link!

Here's a close up:



There wasn't total lost of control as the servo could still move the push pull arm.

I fixed this over extension by limiting the servo link using a long screw I got from one of my old servos:

This limiting screw had to be placed (and bent) so that it contacts the servo link at exactly where its movement is maximum (during max pitch and max aileron):

With this screw in place, I've never had an over extension of the Pitch servo link anymore!!


Curiously, I don't face this problem on the Aileron servo side. Dunno.
All the better.

To clearify, this is my servo arrangement, as per Futaba receiver's requirement:

Right. Now for some blings. I bought this really cool alum canopy mounts from WATTSUPRC:

This is the "before" pic:



And the "after", where the mount is basically just screwed on:

A very nice bling:



But I later found out that the mounting screw is very soft (arrow below):


They broke off after only a few flights (coudn't carry the battery weight).

To fix this, I first filed the mounting surfaces flat, followed by drilling a 3 mm hole:

I drilled to a depth of about 1.5 cm. Then I took the ends of a bent up fly bar rod, cut it and inserted it into the hollowed canopy mount:


I simply CA-ed the shaft onto the alum mount (arrow).

Here's the end product:



A solid mount with an unbreakeble screw.

Right. I off to the flying field.
Happy flying! :wink:

Very nice flying weather off late. So today I tried my first series of loops, rolls and inverted hover:



I'm glad to say I didn't crash!

Here's a short vid of my flying, thanks to my gf who grumblingly agreed to video tape it (thanks honey!):

Well, my inverted hovers are getting lower, thanks to repositioning the lipo higher. Rolls are also 'easier'. Here's a vid of the heli trying to cut grass:
