Walkera V450D01/D03 - Beginner Settings

UPDATE:

I tried some random v4 models of mine in the v3 emulators (Devo 7e, 8, 10). When the model loaded the default screen was completely blank and the switch icons didn't display correctly.

I deleted the gui sections and when the model loaded the default screen was completely blank and the switch icons didn't display correctly. It didn't load the default layout either.

All the settings and switch assignment were correct.

There is a message that I can't correct: Ch3 is 0% safe value = -100%
or Ch1 is 0% safe value

I do have [safety] Auto=min and the message still appears.
And the flight mode switch is on FMODE0.

So v4 models won't work in v3 without applying a layout and correcting the Safety message.

I will list in all my model posts that the models will not work in v3.

Sorry for the beginners question (it may be posted in the wrong place.)

I recently got a v450d03 (with the devo10), without flying the kite i installed deviation 4.01. put in Toms models for all my kites and went for a fly (so I dont know what the standard firmware is like.
I also have a nano, mcpx-bl and trex450 clone using a walkera rx2702.

Situation:
All the heli's fly and are pretty stable but they bob up and down every few seconds and randomly want to drop down a few feet when flying/hovering level.
This doesnt happen with my spektrum dx6i for the nano and mcpx.

I setup a standard kite with simple gui from scratch and it happens as well.
This morning, doing a low level hover, no hand on throttle, it dropped from about 3 feet straight down, hit dirt and broke a blade.
I was testing whether it was my fumble fingers or not (not my fingers)...


So I am wondering if it is a tx thing or a deviation thing.

Ideas anyone?

p.s. Thanks TomZ for models and help on how to configure the software.
coming from a dx6i and wk2801-pro to the devo 10 advanced gui is a bit of a blow to a beginner.

Sound like you have interrupts in the transmission. You can try this on your workbench since most receives flash different when loosing signal. With the small Blades you can recognize this easily.
To get sure if the tx or deviation is the origin of this behavior you should install the stock firmware and test it with the rx2702 (on the bench, of course). It is very likely the transmitter since nobody could fly with deviation with such a fault.

thanks for the reply and I thought it may be tx.
I dont think there is a signal loss as other channels are not affected at the same time.
with the v450d03, I thought maybe it was ESC but when other heli's did same thing it was a bit strange.
not seeing any mention of it elsewhere, I was hoping someone else had seen this type of activity outside of deviation.

Oh well. more learning. maybe I should get a devo8 the screens look nice.

thanks again.

I have seen this, but only with deviation and only with mCP-X, nanoCP-X and mCP-X BL - and it was in every case the LDO (voltage controller) on the rx board. Sometimes when the battery is nearly down suddenly so much current was drawn that the voltage fell below the threshold and the LDO went in...
But this is not very likely the case for non-Blade helis.

again thanks.
my trex did a similar thing and I replaced the esc and it was all good. I figured a low voltage issue may have caused it.
mcpx has low voltage safety so that should be fine.
the situation is almost like I am letting throttle drop for a second and then picking it up again. (hence my hands free crash)
I will keep reading and testing and if I find anything will post.

cheers

Quick question -

My new V450D01 V2 arrived yesterday

I've loaded DeviationTX V4.01 and your model config onto my Devo 10.

With the DEVO protocol the rx would not bind so I changed it to the WK2801 protocol and it binds nicely.

Throttle hold on - move the throttle up to watch the swash - swash moves but only front left aileron moving up - nothing else.

Is that due to the FBL nature of the heli? Elevator works fine. Aileron right has the right servo pushing up, left servo only moves slightly down. Aileron left has the right servo moving down, left servo moving slightly up.

Again - is this a function of the mixing of the FBL gyro?

Emulator shows all the channels working correctly but I'm a little nervous about taking her out for a maiden flight.

Cheers

Something isn't correct.

I just download the model and checked it. Also did a test flight.
Everything checks out fine.
Throttle hold works correctly in all flight modes. The swash moves up and down
with throttle hold on while moving the throttle up and down.

It only binds in DEVO protocol. I tried WK2801 protocol and it won't bind at all.

I'm not sure what to tell you.
Does the swash move correctly with throttle hold off?
The receiver on the heli is a Devo receiver, correct?

I would not fly your heli until you are sure everything is working correctly.

Thanks - I've found the issue. I purchased it off eBay and it's V1 not V2. RX is a RX2801V 3axis gyro and set for mode 1 not mode 2.

Found the manual for the RX which shows how to set it for mode 2. Once I've got it set correctly I'll report back to let you know how it works.

Cheers

Your welcome.
That explains why it didn't bind in DEVO protocol but did in WK2801 protocol.
Some of Walkera's receivers came in 2801 compatibility and some were Devo compatibility. These are for the older helicopters that came out before Walkera completely switched over to all Devo receivers. They stopped making the 2801 compatibility receivers and WK-2801 Pro a long time ago.

Sounds good, let me know how it works for you.

Oops my mistake - it's an RX2702V receiver. According to the manual the mixing is done on the TX.

Will follow the manual instructions and get back to you.

(a little pissed off as I wanted the 6 axis gyro and mg servos - must read all the information before buying lol)

Ok I've spent some time getting everything moving correctly.

Mixing is done on the TX for this receiver with a 120 swash.

Right now all the controls work correctly. I started with getting the collective working properly before switching to reversing the servos.

Attached is a copy of the model file. I've opened it in the emulator but realistically I have no clue.

Would you mind taking a look at it for me please?

Cheers

Is your receiver for the Devo transmitter or for the 2801 pro transmitter?
From a google search I did there is a RX2702V and a RX2702V-D. D is for Devo transmitters and if there is no D then it is for the 2801 pro transmitter.

Also you said Mixing is done on the TX for this receiver with a 120 swash.
You will need to change this. My model is set to 1Servo normal for Mixing is done on the receiver.

The model you posted is not correct, I wouldn't try to fly using it.

If your receiver is for Devo then all you should need to do is change the swash type setting.

If your receiver is for 2801 pro then all you should need to do is change the swash type setting and change the protocol from DEVO to WK2801.

Well I've been working on this for a while now. With the model you've put on the first post I've changed the protocol to WK2801 and the swash to 120 / 3 servo.

It's def the RX2072V (non-devo).

Unfortunately it doesn't more the swash in the correct manner.

With the model I posted the swash moves correctly - ele / ail / pitch all correct.

I'm not confident tho. On spooling up it spins CCW as if the rudder control isn't correct.

Will keep working on it.

Cheers
