If they cared enough, they'd just try to go after whoever makes the copycat orange RXs.
Orange RX's are "compatible" not cloned. They are also on the MAAA's list of accepted radio equipment so I wouldn't call them "iffy" either. (Walkera radio equipment is not though, and is effectively banned from MAAA fields)

Personally, I would do that in such a way that the thing fails randomly in the air. Kinda like the infamous Black Sunday back-hack.
No company would do that because if someone were injured or killed it could result in a lawsuit or even criminal prosecution. Designing your radio equipment so that it deliberately causes a potentially lethal aircraft to go out of control would land you in serious $%#^ if it were ever discovered.

I've read about it but I hadn't heard that. It's all very interesting but it's only one of the reasons not to use hacked stuff unless you have a margin of error.

I've had Spektrum, Older WK, and the new Devo radios. I prefer the sticks of the Devo 8s any day. But that's MY opinion.

Horizon's stuff is more expensive (for example, $11 for a cheap Chinese main motor that fails after 30+ flights for my Nano). My Walkera micros have a MUCH more stable FBL system (it's rock solid stable and WAY easy to fly without having to put bullet blades on it), are cheaper and are equally capable as my Blade helis. I shouldn't have to be cornered into buying another $350+ radio just to fly Blade helis, when I have a perfectly capable Devo 8s, which is of GREAT quality, IMO.

That's not to say you're well within your right to use DXx radios and only buy cheapos to fly other brands, if you want. But I'm at the point now where I don't hold either or any brand in higher regards as my "primary" brand, except for my radio hardware itself. I prefer the feel of the Devo 8S, so I use it. I just want to be able to buy any heli I want to use with it without having to buy yet another TX.

I'm proud to say I fly an AR7200BX Trex 250, Nano CP X, HP05 mCPX, HP05/03t double brushless Mini CP, and a V120D02S, all with my Devo 8S. Flawlessly. No bugs, no glitches, no unexpected behavior.

Everyone is entitled to use what they want, and I should be entitled to use my Devo for all of those, if made possible by the brilliant programmers of the Deviation project. It's my opinion that this firmware is the best thing to ever happen to RC.

I am surprised you like the devo8 over some spek radios. I prefered the dx7 and dx8 feel over the devo8 and devo8s. My devo12s had very nice sticks, but felt much cheaper and even with an amazing touchscreeen it didnt compare to my Jr which was about the same price. I guess everyone has a different feel for things

What I really like is some of the additions that walkera adds to their radios like touch and the recent addition the fpv monitor screens...what i dont like is their resell value and support.

On motors you are right blade replacements are too high but even Walkera seems to be ever raising their pricing too


As far as stability of Walkera i too found the minicp a much better heli than the mcpx, though walkera has nothing out to combat the nano or flys close to it. It will be interesting to see what they come out with down the line.

If you have a chance try comparing your 120d02s to a 130x. I really loved all my 120's when i first got them as nothing else came close too them.

On the Deviation firmware, while Walkera has some good radios that can be made to work with other brands I dont think any decent cllub would let you fly larger models with such a modified tx. For park flyers I dont see a problem unless you hurt someone else which probably is pretty unlikely...but be carefull flying that 250 size and above

Personnaly I'm sure I will found more help on the web with the community....
I never had any help from big Cies like Microsoft each time I've had problems on my computer with windows xxx (which I've paid to Microsoft) ... I always found support on the web... thanks to community.

Illegal where? In the US yes thanks to the DMCA, but elsewhere it's not because reverse engineering is still legal most places outside the US if you're careful about how you go about doing it.
I know, I've resurrected an ancient thread, but the above piece of BS caught my attention, and I'd like to make sure that others don't see it and think it's correct. The age is why I've removed the attribution.

The DMCA doesn't make reverse engineering illegal. It makes breaking encryption software designed to manage access to intellectual property illegal. It even has an exemption for reverse engineering.

As far as I know, nothing in US law makes using a non-spektrum DSM Tx or Rx prima facie illegal in the US. Selling any Tx without an FCC permit is illegal, but has nothing to do with the DMCA or other IP laws. Claiming they are Spektrum hardware or licensed by Spektrum would be a violation of Spektrum's trademarks, not the DMCA. If you copied code from a Spektrum Tx or Rx, that would be a violation of copyright, but only a violation of the DMCA if Spektrum used some form of rights management to prevent that copying. Reverse engineering doesn't copy the code, and is again exempted by the DMCA.

Finally, Spektrum has a patent on their dual link satellite system, so any gear that implements it exactly as Spektrum does is probably in violation of the patent. Not clear if you can do what Spektrum does without violating the patent, nor if using a simpler diversity system would violate the patent. Not applicable to transmitters, so I haven't looked at it closely.

Either using two antennas (not dipole) isn't in violation or everybody is violating.

Did you know that Boeing has a patent on adjustable servo horns? I mean the kind where you can turn the servo horn to any angle and then clamp it onto the shaft like these:



As far as I know nobody who makes these for hobby R/C use has bothered to license them from Boeing. Because this is a defense industry patent if they did it'd probably make them far too expensive anyway.

we're getting off topic but that is very interesting. i never thought about servos being used by the military but immediately things like cruise missiles and other guided devices comes to mind.
well yeah and drones too, duh..

i agree with that.
i would get a 10 if I didn't snag a Taranis on sale. Now I just have to learn to mod it for DSMX, not as easy as Devo.

Devo 10 is a nice radio except for two things.

The gimbals wear out fast and start getting creaky on Walkera radios.

There is no place to send them to be fixed and you can't get replacement gimbals to fix it yourself.

Walkera's position seems to be that if it breaks you throw it away and buy a new one.

I'm the other way around - I bought my 10 a month or so before the Taranis became available. if I didn't have the 10, I'd buy the Taranis instead, but it's just not quite enough of an upgrade to justify the cost.

BTW, the 10 is a 12 channel radio after you install Deviation on it. Even with DSM. Spektrums arbitrary limits on the number of channels is one thing that really bugs me about them. I mean - the number of channels is a software issue, not a hardware one. So the limit is effectively a marketing ploy

Actually it could also depend on how powerful the CPU is in the lower tier models but I suspect you are right. The DX4 and DX5 *are* limited to 6 channels by hardware though. The radio board can't transmit more than 6 channels.

Well, the Devo 7E has a STM32F103 in it - a 72Mhz, 32 bit procesor. I'm pretty sure it won't have problems sending 12 (or more) channels.

That the low end Spektrum Rx's let the RF board do the packet formatting just means the code that's imposing the limt is in the -controller on the RF board and not the one on the main board .

I forgot the real issue here - and the one that's why I bought an TH9X and later the Devo's. The proprietary UI model is to figure out everything the user might want to do, and then give them tools to d those things. So a 5/6/8/10 channel Rx won't have configuration options to let you do anything with more than the number of channels you have, and they compete on a feature list that's what they've decided to let you do. With an open source firmware UI, you get the ability to do nearly anything - if you can figure out how. Sort of reminds me of the difference between MVS and Unix. There's a place for both models, but the channel limits still stick in my craw.
