since I change to futaba TX and always hated the tilting servo; I designed a frame conversion for the XL 1005

I came with the design thinking in a Vario Benzing style CCPM, using 4 bellcranks and 4 servos for an "X" CCPM

the frames will be made of 2mm carbon fiber

here is an image of the frame plans:

if anyone is interested in the Autocad file to make this conversion, yust sendme a PM with an e-mail to send the file

any ideas, thoughts, coments are welcome

thankyou

Nice work!
Mine is 3 servo CCPM, I got the two up front like you have them on the bellcranks which are moved slightly forward to line up properly and the one in the back with a bellcrank to drive the rear of the swash.

You'll probably find a picture of it in my gallery.

I alrready have done the 2 servo 180 degree CCPM

The aileron and pitch servo are mixed in a 180 desgree CCPM, but you still need the arm for the elevator (wich i dont like of course) this conversion works perfect, in my gallery you can find 2 images of this conversion. You yust need a new servo plate. The problem with this conversion its that not every radio has a 2 servo 180 desgree program. I had it with an Aurora 9 froom hitec

Yup Luis
I call that 2 servo ccpm, my JR radio handled that. Had it for a while until I converted to flybarless and then went to 3 servo ccpm to be able to support it.

I meant the two servo up front for 120 degree ccpm. the elevator servo is fine where it is all u need is the elevator bell crank from the tempest or fury like the way raja's friend does it

well I am going to be an old poop. Congrats to Luis and Raja for "updating" the very old 1005. I have seen Raja's 1005 fly every bit as good as his Spectra and Whiplash before and after the "upgrade". I do know the upgrade by Raja must be better but I could not tell a difference in his hands. I being an old poop Like the old swinging tilted servo mechanical setupin the 1005 and have no plans to change it. I just keep changing out ball links to keep her as dialed in as possible. It is amazing how well this old system can still do the job. But that is me and my recently recently run in Spectra is surprising me too in how she flies. A good bit more connected,,a great heli too for sure and I am still learning alot!. A very different bird ,,,I love it!! Both too me at least are equal in their very different approach with very different personalities . My 1005 will forever be as it was from the factory ,,,the Spectra I hope will soon be flybar less.

Setup is everything, All my heli's can fly far better than I can pilot them

turboomni: I think you are wrong

If you like the swinging servo is OK it does the job. But, the day i made the first flight test with the 2 servo 180° CCPM; I was amazed the way the heli changed, it was allot!!!! more precise and predictable. Electronic CCPM works allot better than mechanical CCPM that´s for sure

I just had a look at your CCPM set-up and it is very like the old Schluter System 99 set-up except it now uses servos on all bellcranks for e-CCPM. The Schluter system of course uses three rocking servos to achieve a mechanical version of this style of CCPM and is a very connected control loop method.

Turboomni I think you are wrong
I know I am wrong!! I know a CCPM setup would be a night and day difference and much better than the 1005's stock setup. I just like the idea of it being historically correct and enjoy flying it's antiquated design...thats all. Then I go fly my Spectra!!

Hmmm
Lots of work there, I think you complicated it a little too much with 4 servo ccpm. No offense there hope you don't take it the wrong way, but why not keep it 3 servo ccpm unless you're worried about servo reliability?

To that I would say buy the BEST servos money can buy, and that way that would not be an issue.

Congrats on the excellent fabrication work, I mean that you did a nice job just wanted to say you could have probably made it simpler, that's all.

I just like the 4 servo configuration

I don't like the servo on the back, too little room on the upper frame inside for a 3 servo CCPM

and yes!!!! it´s complicated!!! it had a lot more work than I thought

but finally done!!!

What are the benefits of a 4 servo configuration over the 3 servo CCPM?

turbomini:

in my opinion, the 4 servo ccpm it´s more safer for bigger and heavier helis like a gas helicopter and even more for an 800 helicopter. The collective and ciclic are working with 4 servos of 124 oz of torque (6V) each one, the result is a ciclic and collective mechanism of 496 oz of torque in each channel, because I´m using the 4 servos in "X" format; in this configuration of CCPM each channel works with the 4 servos, but if one servo fails for any reason, you still have a fully working CCPM
