Posted by chuck4040 on 01-22-2010 02:27 PM:
Any thoughts?

What impact would the E620's 90 degree CCPM have as it relates to the FBL unit, if any?

Thanks for any input.

According to all of the literature, it should work fine. The Align unit supports 90 degree CCPM.

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!
RE-KIT!!!!!

I had the oppotunity to play with one and maybe I missed how it will work with anything other than a 120deg ccpm machine.

The unit takes in signals already mixed to 120deg ccpm. This has no affect on how the gyro adjustments to the servos are made. The issue I see is on the elevator corrections. For 120 degree ccpm the front 2 servos will move about half as much as the rear servo. For 90 only the rear servo should move. The 120 config may work but I think there will be some over travel issues to deal with.

Someone else please chime in...

It works perfectly. You don't even have to make any setting changes, just follow the 3G setup steps and the system will automatically pick up the fact it's a 90 degree mechanical mixing system. Here are some photos from a guy who has been flying it for a week now.

Will it support the E620 140 eCCPM option?

I have heard there are issues in getting the swashplate level throughout the connective range. Has anyone come up with a solution to this problem?

Although I have not seen it on a E620 with eCCPM, I don't see why it wouldn't work. This unit has been tested with many, many helis with different swash control setups.

The beauty of the 3G system is that as long as the swash is leveled at 0 degrees, any interaction induced swash movements are compensated in flight. My heli climbs perfectly straight right side up or inverted.

Who in the US has them in stock?

Not sure - my Local hobby shop had two - one for a 600 and another for the 500.

So you can put it in a mode that only moves the rear servo for an elevator correction?

Well...now that I think about it if you do the elevator travel step the 3G will see that only one servo moves and probably switch the mode internally. The only reason I ask is I help quite a few people setup fbl helis with man different systems.

yup the step where you set the aileron travel limit actually lets the 3G system recognize your mixing type. No need to set it to 90/120/140/etc degrees. Pretty slick.

I don’t want the ones with Align head parts as I already have several heads. I want the universal flybarless unit with no other hardware.

Srimok
hey! how about the Align 3G working on a Srimok 90,I was kinda contemplateing it for mine I figure it should work but I'm really not sure.

E620
The same issue is true (I think) for the Gyrobot 700 that only supports direct (mechanical mixing) and 120 degree swash.

The Raptor 620 is either a 90 degree swash or 140 degree upgrade option
The direct mechanical gyro option will not work as it expects the mixing to be done mechanically as on the Nitro Raptor 50 via 3 independent servos. in this mode only the pitch servo will move, so not a lot of use, there will be not be any swash mixing inside the gyro.

The 140 degree swash with 120 mode in the gyro selected, will work kind of, as in the servos will all mix and move in the correct directions but the internal swash mix will gives unwanted collective interaction when adding elevator due to the geometry differences between the 120 and 140 swash's. Not sure if there is a way around this with internal gyro settings, I haven't been able to find them.

For my 620 I am using a 120 Swash and will be making a sub plate to move the pivot point of the swash levers to bring it to the correct location to suit the swash.

I don't know about the gyrobot, but the 3G has been tested on 90 degrees mechanical system, as well as 120/140 CCPM. There is no setting. It's recognized automatically during the setup process.
Posted by CT.Chopper on 02-06-2010 04:00 PM:
it does not work with 140* ccpm,
collective works properly, however elevator foreward the swash drops and backwards elevator raises the elevator...

i played with diffrent length ball's and cannot get the
140 to work properly,

im converting it to 120*

Are you refering to the 3G or gyrobot?

This is the first instance where I hear 3G doesn't work with 140. Have you gone through the setup procedure? step2 where you set the elevator limit is where the system recognize the swashplate type.
Posted by CT.Chopper on 02-06-2010 06:59 PM:
the 3-G,
I have actually tried it and am not specuating,

i have tried it on 120 and 140 radio swash settings.
and yes i know the proper set up procedure,

the elevator set up measures radio input not swash interaction,

Posted by CT.Chopper on 02-06-2010 07:30 PM:
by swash interaction i mean,
the 3g cannot tell if the swash is level,
it is based off the servo input signals, thats why a proper set up is very critical..

a 140 degree swash has a short ball on elevator and longer balls on pitch and aileron

i have tried various lengths on the swash control trying to get it to work.. 120 degree swash works perfect.

Posted by steph280 on 02-06-2010 10:33 PM:
You enter the DIR setup mode with your swashplate level, 0 degrees pitch, servo centered. After you set the collective and cyclic pitch and press set, it will remember this position as the basis, where your swash will be level. It should have no problem getting back to this position. In step two when you give elevator input to set travel, it will calculate the amount of servo movement and determine the swashplate angles. It actually doesn't care what is on the swashplate, it just needs to know how much input each servo needs to achieve forward elevator.

Of course if your radio wasn't setup for 140 CCPM to begin with, it will not work.
Posted by chuck4040 on 02-06-2010 10:46 PM:
Then the theory is the same for a 90 degree setup???

Posted by CT.Chopper on 02-07-2010 01:14 AM:
steph,
it does not work .

it will give you collective with no interaction.
aileron with no interaction.
elevator has interaction.
i have tried it myself on my own helicopter right here in my house
with my own 3G and seen it with my own eyes..

it is designed for a 120 swash,
i tried everything.

chuck,
just get a 120 swash and make brackets to move the bellcranks 20mm closer, use the 2 bellcrank mounts to secure the new bellcrank and fly.

Dammit...now you got me wondering why it wont work..
in theroy it wont,
however like i said i fubbed with it for a couple of hours...
ill try again tonight.. stay tuned...

Rob Landry.

Posted by CT.Chopper on 02-07-2010 02:25 AM:
nope..
dont' work with 140 swash...

i would bet the programming usb link will fix that though...

Dude,

If you need help, I stop over tomorrow and straighten it out for you.
Posted by CT.Chopper on 02-07-2010 02:48 AM:
I got somethin' for you that'll straighten you out....---->

fooo.

LOL I feel the love there!

I love to hear your result if you ever do get it to work. Please keep us posted.
