ECO8 Re-Build w/bling

Well you guys talked me into it.

I just bought a used Futaba 6XHS FM/PCM with a FP-R148DF 8 channel receiver and a couple of 120 degree brackets.
And thrown into the deal also a 4 channel receiver and channel 42 crystal Electrifly from Great Planes.

So if anybody would like to make a offer on the 4 channel receiver (channel 42), When I get it I would be willing to sell it..


I went thru the owners manual and it looks like a nightmare to me to program it. If anybody out there could help by walking me thru it I would appreciate it.

What would you ECO8 owners suggest to put into the different settings ?

How do you start the blade up ? Before it was by slowly moving the left stick up. But now it will be blade pitch control ?

I would expect that you are going to switch to CCPM, if so then you need a 6 or more channel reciver. I use the same trans. with my eco and my only complaint would be the throttle curve only has one point to adjust but if you use a speed control with a gov. then who cares.

Blade pitch and throttle will be blended together just like the mech. mixer but now it will be done in the radio, pretty much everything will be exactly the same........Impact

It's not bad setting it up, Select the right swash setting, then get all the servo's going the proper direction, then set how far they go and your ready to for some test hovers......Impact

That will hold the throttle up when the throttle stick is less than 50%. In normal mode you will have a throttle curve that is linear like this, 1/4 stick = 25%throttle 1/2 stick= 50% 3/4 stick = 75% full stick = 100%

When you flip the switch into "Idle up" you will now have a throttle curve that looks more like a V, example
0 stick = 100% throttle 1/4 stick = 75% 1/2 stick = 60% 3/4 stick = 75% full stick = 100%

That will shut off your motor and allow you to do autorotations. When that switch is on the left stick will only control the collective.........Impact

So idle up would be for like 3D, so that when you are upside down you would have full head speed . Or if you wanted to go down very fast if upright.

Thanks for the heads up. I am very new at this computer radio stuff...amazes me at just what you can get a small radio to do !

I start in normal mode and move the left stick up to the middle. This starts the motor and spools up in neutral collective which is smooth. Then I flip to Idle Up and I get a flat throttle curve and negative collective pitch. Nw the helicopter is ready for flying and the middle position is the neutral position. When I want to shut down I switch back into normal mode and slowly lower the stick to the bottom. I use a flat throttle curve because I use the governor mode in my ESC to keep the RPM constant. My transmitter has five point curves and if I had had a transmitter with just three points I would disregard the 25% and 75% stick positions.

I don't know if it helps but here are some example settings:

Normal Throttle Curve:
Stick at top - 75 % throttle
Stick at 75 %- 75 % throttle
Stick at middle - 75 % throttle
Stick at 25 %- 37.5 % throttle
Stick at bottom - 0 % throttle

Normal Pitch Curve:
Stick at top - 100 % positive collective
Stick at 75 % - 50 % positive collective
Stick at middle - neutral collective
Stick at 25 %- neutral collective
Stick at bottom - neutral collective


Idle Up Throttle Curve:
Stick at top - 75 % throttle
Stick at 75 % - 75 % throttle
Stick at middle - 75 % throttle
Stick at 25 %- 75 % throttle
Stick at bottom - 75 % throttle

Idle Up Pitch Curve:
Stick at top - 100 % positive collective
Stick at 75 % - 50 % positive collective
Stick at middle - neutral collective
Stick at 25 %- 50 % negative collective
Stick at bottom - 100 % negative collective

Man is this addicting.
I now have the computer radio coming.
Also I just ordered the (like the red ones, last blue set they had) blue side frames, blue center frame support and the kind of blue 120 degree servo mounts.
Last week I got the red alu swash plate (no blue available). I am going with blue since my ECO8 will be mounted inside of my blue Jet Ranger body later this Summer...

I found a very good article on setting up my radio for the ECO8 at >> http://www.dream-models.com/eco/radio-6XHs-ff6.html

So I will use a combination of your suggestions and his procedure..

Gee next month maybe the lower frame brace and more ! Wish I could find it in blue ! I have found some of the pieces in blue But the main lower support in just red...

I think you'll be pleasantly surprised by how much better the ccpm setup handles. I never set up the oem mechanical mixer for the the Eco, but I never heard anything good about it. Just make sure you use identical servo models for all 3 swash servos- don't mix gear types or anything.

You might consider some aluminum servo arms for the swash servos. They are usually a little longer than the stock plastic ones so you'll get less unwanted cyclic interaction at control extremes since travel will be more linear. They also flex less and they also look cool.

The only thing I don't like about alum frame sides- if they flex or bend, they tend to stay a little bent. Carbon will flex but will always go back to its original shape- provided it didn't snap. Either way, it's much nicer and stronger than the oem plastic.

Another victim/member of the upgrade club. I accept no responsibilty for this....

What are Hitec 82s? I'm guessing you meant 81s. Anyways... I think I picked mine up from my LHS, but I think these are the same ones:

OK I have been reading thru the manual.
If I understand it correct. I will loose one of the functions I now have.
Mainly I can turn my landing light on/off remotely. By using channel 5

But the new set up will be
Channel 1 - Aileron. This goes to the servo on the left side of the swash
Channel 2 - Elevator. This goes to the servo on the back of the swash.
Channel 3 - Throttle. Goes to your ESC (also powers RX via the BEC)
Channel 4 - Rudder. Goes to Futaba 401 gyro and then to tail servo.
Channel 5 - Gyro switching HH/AVCS
Channel 6 - Aileron Goes to the servo on the right of swash.

So is there a way I can turn the landing light on/off remotely ? Or would I have to put it in channel 5 and just fly head holding all the time ? If so how do you tell it to start up in HH all the time ?

Below is a picture of my controller I have coming if that will help any I have a 8 channel receiver coming. But I assume they would not be usable without a 8 channel transmitter..
What is the hovering pitch channel 6 ?
