Having worked with all three -I can safely say that reboot IS NOT a function of power!
You are apparantly talking about rx shutdown due to power loss.
All three brands come back on line instantly when power is returned
Where did you get your info?
If you are referring to a shutdown of the TX-- then reconnect times can be of various lengths
Shutdown of TX is not a power issue

both my spektrum took several seconds to recover from brownout. i used that gear in planes for a couple months and never had a problem but the quicker boot time of the chinese units was enough for me to switch. it has been couple years since those tests were conducted and i dont recall the actual model numbers. they have probably fixed it by now but still..

Wow, you must have had ancient recievers. Why didn't you send them in for the free update? The Chinese copied the newer (not newest) code, not the oldest stuff.

they were among the first 2.4ghz sold in usa. dsm iirc. as i mentioned earlier the spektrum stuff was given to me by a friend who lost thousand$ in crashed planes. i used it for a couple months w/o any problems, however he flew at crowded fields and i do not.

i never bother with updates on anything. specially something i dont use. basically if something fails i just grab one of the backups from the closet and keep on trucking. i was able to buy dozens (no exaggeration) of rx and a 9x for less than one brand radio. since then picked up another on one of hobbykings $40 deals and got a 3rd from a local "patriot" who just didnt like his.

btw i also have a futaba which is collecting dust. i think it cost over $1000. it was given to me by a fellow who broke one of the pots and when he saw how much they wanted to fix it he switched makes. they wanted more to fix it than you can buy a turnigy for. eventually on one rainy day i put a regular radio shack pot in and used an op amp to make it work like an rc pot.

I would put them all in a box, spent the $10 on the postage, and when they return have a box of known-reliable receivers ready for airframes!

So who's fault is it there's all this distrust, Spektrum for making radio it's easier to make a mistake with or the ignorant users?

Similarly, when my big new chargers popped the circuit breaker, that was the charger maker's fault for selling chargers that were too powerful.

Of course, if you buy a RTF or BNF and expect it to behave like a toy/appliance, and it browns out, then I think you have a real argument that the RTF/BNF maker messed up. But if it was a kit/ARF where you were involved in the component selection, then I'd have to say that these learning opportunities are part of what separates hobbies from just buyin stuff.

Likewise, the guy at our field whose electric plane flew off the bench because he ASSumed his Fubata had model match just like everyone else's radios. Nothing really "wrong" with his radio - he just needed to understand it better.

you know i may do that someday if they ever go up for sale but for now all that stuff looks cool on the shelf of my "radio museum". or maybe if i hang onto them long enough the value will skyrocket due to antique appreciation. i saw a kraft one stick go for $300 on ebay couple weeks ago. lol!

to tell you the truth my favorite tx right now is a v911 micro-heli remote upgraded with 9x firmware (see core9x). true, the sticks feel real cheap and not many buttons/switches but for me ergonomic heaven. its the only unit i know that allows hand launching planes and helis without resorting to harness or tray. yet i still have most of the power and versatility of er9x:



ok, i now leave the floor open for ridicule..

This quite humourous. A guy, probably not a product user, asks a dumb question and then probably watching the show and the defense by a rep and a heavy duty user.
Everyone should ignore this thread and let it go away.

Many of us took the high road when Spektrum was having their problems and provided a lot of information about those problems behind closed doors to the manufacturer. Some of the banter about these exchanges was publicized and discussions were heated with a few (and I do mean FEW) loyal team pilots calling us idiots and blaming our installations for all of our problems. After having our intelligence and integrity directly assaulted publicly, many of us did do exactly that... moved on because of a lack of trust for the gear.

It was interesting when the 6250 was recalled, as this was the receiver I had all of my issues with. It gave me a pretty solid feeling of vindication. BTW I had problems with the other brand I used after Spektrum, but they were cooperative and worked to fix the glitch in their system that was at fault. Companies have an opportunity to shine when there is a problem with their product. This company earned my loyalty by diving into the problem, identifying it, fixing it, and apologizing for the error.

I'm now playing with JR again as many, many of my friends are long time JR guys and some of my friends are employees of HH. I really like the XG8 and it seems like a radio that could pull me back. I don't see anything coming from the other manufacturers that compels me to change right now. What I will not do is ever again fly anything with the orange bars on it. Call me crazy if you wish but when you get a really foul taste for a product it can take a long time to forget.

Normally I ignore these threads but for whatever reason I felt like posting. BTW... I did not let it infringe upon my enjoyment of the hobby, or my friendships. These are toy airplanes after all.

Yes,

I edited my post to read "spectrum" instead of "Spektrum". One is a signal type, one is a manufacturer's name.

It's not even certain that a Spektrum radio system was in use here. Maybe this is part of the answer to the question we're discussing. As we've all just seen, many people tend to blame the radio system for a crash even when the actual cause is elsewhere, which means that the most popular radio system will get blamed for the most crashes.

Here's some dirt on FASST systems, from our friends across the big pond:

FASST is an acronym for Futaba advanced spread SPECTRUM technology.

Are you talking about the DSM2 clones, or the FrSky and FlySky systems that Dave1993 was referring to?
