Hi i have a trex 450 pro v2 DFC and devo 8s with the following

3GX with 2 spectrum DSM2 sats
WK-CTL01-D telemetry with rpm sensor
KST DS215MG servo's
Pheonix ice 50
Scorpion HKII-221 brushless
Turnigy nano-tech 22v 1300mAh 6S1P 35~70C Lipo
all alloy upgrades

I decided to go with the devo 8s so i could use the one tx for other helli's, So far i have used this www.deviationtx.com/forum/model-configs/...walkera-2702v-3-axis for my setup.

I can get it to bind with out a problem but the servo's just aren't right.

any help would be appreciated

You can't use the CTL01-D with DSM2 receiver(s).
It won't do anything...

Could you be more specific?

Sorry for taking so long to reply

When i move up on the throttle my collective pitch moves up slightly then back to centre when i reach mid way then repeats the same till i reach the top.

Do you really need inverting the AIL and COL in the swash menu?
It seems more reasonable for me without them...

With DSM2 the channel order is different.
1-Throttle
2-Aileron
3-Elevator
4-Rudder
5-Gyro
6-Collective Pitch

I'm not sure about the 3gx, but for the FBL units I've used, you don't do any mixing in the radio. i.e. you don't use cyclic1,2,3.

I'l post my blade 300x config in another thread. Have a look at it and you can use it as a base to get started.

Oh, I forgot the DSM2 satellites in the OP! :blush:
The channel order was appropriate for the selected DEVO protocol...

Don't know either if the 3GX would need CCPM, but I guess not...

So we are! ;)

You wrote, you use a 3GX with DSM2 satellites as receivers, but your model.ini is configured to use the DEVO protocol. It shouldn't bind that way...

The WK-CTL01-D telemetry sensor cannot work with DSM2 receivers either.

The config you posted has the channels in the wrong order.
When you select DSM2 as the protocol the channel order is set to match spektrum dsm. Which is what I posted last post.

So that's the first problem.

Second problem is the most fbl units do the ccpm mixing for you so you do not need to have the 8s setup for cyclic mixing. Just straight aileron (ch2),elevator(ch3) and pitch(ch6). ch1 is throttle and ch5 is gyro control. This of course matches up to the DSM protocol and if you have the order wrong, it won't work.

Sorry about that i posted the wrong model.
I just upgraded to deviation v2.0.0 with the standard 6 channel template and it is much better than the last version i think it is just the 3GX calibration now will play with it tommorrow and post the results

Thanks Hexperience it was the combination that was wrong and i went back to v1.2 but i did have to do CCPM for the 3gx.

I now have it working for both DSM2 and DSMX satelites just need to do some fine tuning with the 3gx and set channel5 for gyro.

Here is the model ini

Interesting. I've never had a 3gx to play with. I'll have a look at the manual and check out the recommended tx setup.
Cheers

with Devo 2.0 you have to define 1 channel more !
if you have a 6 channel receiver you must choose 7 channels in the heli setup menu.

cheers

yes i mean the new deviation firmware 2.0.

In the protocol setup menu you can also choose the number of channels for the DSM2 protocol. I have a T-Rex 250 with
3GX and sat receiver, and it works fine with selected 7 channels.

How did it turn out?

I just got the 450 v2 with DFC and 3GX. I also have a devo 8S from my Genius and am looking to fly the 450 with my Devo 8S.
