Any chance of getting frsky working? I'm running low on devo receivers and have a bunch of frsky to use... ;)

Note this is the power output from the CC2500 which it what gets fed to the power amplifier that pushes it higher. So +1dBm on the CC2500 is I believe approximately +20dBm output from the power amp.


Hi tx,

Thanks for the reminder and the code change required. I tested both 0XFF and 0XFE and the 0XFE did give a lower output compared to the 0XFF as it should. I saw no other funnies on the spectrum.

Most important is that the CC2500/Skyartec module output with 0XFF is about 2dBm down on the XL7105 and CYRF module output at their 150mW settings. I am happy it proves it's a CC2500 power setting in Deviation and not a HW module or antenna problem.

Hex,

Interestingly your 12S antenna looks like the ones I received with both my 8s Devos. I added two external antennas (like the smaller one on you photo) for the XL7105 and CC2500 modules. By switching the longer and shorter antennas around I do notice a lower output from the smaller antenna, my guess is noit even 2dBm.

Hmmm..

Feel a bit stupid now - having worked with computers since 1985.

I open the Devo disk by pressing ENT when powering on the Devo10.

I then get the filesystem.

There is 5 directories.

language
media
mdelico
models
template

An two files
errors
tx

So getting to the protocol directory, I can not figure out.

I guess You have to feed me by teaspoon :unsure:

I downloaded the *fs'devo10* file again and there is no protocol directory there.

It also seems that there is a difference between Devo7 an Devo10 about this in the Firmware manual... page 7

\protocol\*.mod (Devo7e only):
These contain the protocol files. They must
be re-installed with each firmware upgrade

I think this means that the protocol directory only applies to Devo7 and not Devo10...

OK..

I guess this is the source code and programming I gave up years ago as soon as I was done studying...

I'll just wait for the power issue to be solved in a future release I guess.

Hi Stein

I can build you a Devo10.dfu file to load with higher skyartec power output. PM me your email address.

Hi. Finally got to test my Devo-10 with The Skyartec module and antenna. Used the last nightly build and at 140 meters i ran out of free space and the Skyartec X3V as a 250 size heli at that distance is not visible for my eyes anyway.

So quite happy!

Thanks!

Hey you guys have a config file for wasp x3v. I can't figure out my rudder servo is running really slow and I have 2 wasp x3v and they both do the same thing. Something with gyro sensitivity is set with different channel I don't now how to set this up. Please help.

HI

I'm not quite satisfied with my model file for X3V yet but with this config i got one of my X3V's to fly fairly decent - sport mode that is - no 3D.

I use a Devo-10.

Kill Switch is Rudd-DR
ELEV D/R switch i have two sensitivities for Elevator
Gear switch gives me two gyro settings
Mix switch gives med three pitch curve settings
Aile D/R switch gives med two sensitivities for Aileron
FMOD switch gives med three different throttle setup.

I experienced with this model file that all switches in Zero exept for Mix=1 and FMOD=1 gave me the best flying.

But I also must say that a tiny different setup of linkages on the heli will make the heli act different. I try to set up my two X3V the same - but one flew and the other did not. Found that the one not flying had a curved/bent/damageded main blade. Going to change the blades on that one to see if that was the whole thing.

What i do for setup is first to get the swash plate level at powerconnect. I also watch for the servo arms not to go too far at each side. Next i use a simple pitch gauge to the the blades in zero pitch at mid throttle with my setup with the MIX switch at two (third position) which has zero pitch at zero throttle.

Still i had to adjust offset to get enough pitch. But for sure - get the swash level and the blades act with same pitch is a good starting point. Try Your X3V at work bench - just with power connected - see if they act the same.

Pitch curve and gyro sensitivity then is important.

So - this model file is not to be an example - but more like a model file that works for me at the moment - but I plan to do modifications as I learn more.

I'm using the last nightly build by the way.

Hello guys... I've tried wasp x3v today, just a hovering test and the signal cut off and it fell on the ground so I tried again and the second time I lost signal again. This is happening at about 2 meter away. This time it fell side way, :huh: the esc cut off from the load of the motor. I've did a range test and I get about 50 meters at Max. I'm using a cc2500 module with power amp, maybe it's not plug right or its software problem. This is my 3rd module I've tested ( the others came from skyartec TX and it didn't workout for me ) I have a devo12s and I use the recent nightly build.
Any help would be appriciated, I'm afraid to try it again, I just don't know what to expect. :sick:
I wish deviation would come out with a all in one module that works,... I'd buy that immediately. :woohoo:

It could be a number of things :

- bad motor

- bad esc

- bad receiver
.
.
.
- bad Devo TX, or module

- issue with deviation

To rule out it isn't your helicopter that is the culprit, I would test it with the TX it came in. nasa701 I think.

Then if all is ok, you can investigate your devo12 and deviation code.

Skyartec compability...

I've done some writing here already but about the problems bidge has - they do not apply to my setup - fortunately.

1) I have the X3V and Nano Cp - 4 helis in total
2) I have the Devo-10
3) I use the latest nightly build of deviation software in this site
4) In the Devo-10 I've soldered in the original skyartec modul - bought it directly from Skyartec: www.skyartec.com/ProductShow.asp?ArticleID=1977
5) Since soldering inside the radio and onto the module is neccessary I got a friend of mine which is a professional - but not into RC. He followed the manual also found at this site.
6) First I used it without antenna and had a range about 50m. Soldered a antenna to the skyartec module - and now have more than 150 meters range.




I have flown this setup now for aprox 30 batteries - that is aprox 300 minutes. Not a single fault due to software - just faulty heli setup and my own flying errors. I have flown 10 batteries in a row without any crash and not any surprises from heli/radio/software - just a big smile on my face.

If this result comes from using the original Skyartec module - I do not know - but please check into it before altering the code on this :)

In addition to Skyartec I also has a DSM receiver connected to my simulator - works perfect. I do not dare to think about how many hours. Distance is no problem flying simulator of course...

Stein.

Hello Stein, It was running good with the original TX NASA 701 no cut off and the range was good. I just didn't like that radio and I like hacking and modify stuff its more fun but these skyartec module are a pain in the ass. Now I tried to salvage the module from the 701 TX but no success. So I bought one on eBay . Maybe its not hooked right, maybe the info should be more clear for me. It might need more power to the module. I know I had to power up 3 pins with 3.3v... but everything is not quite clear on how to hook it up, for me anyway. I think I'm gona order more modules. :dry: (pict of the cc2500 module installed in my devo12s).
