Status: offline This lock out problem is maybe due to your flying site having high back ground niose causing you to lose signal & delaying the restablisment of a lock. simply unplugging the battery on the bench to judge the reconnection time is not a valid test because the link is esablised in ideal conditions not at distance when the signal is weaker. This issue is not unique to 2.4gz systems & has been around since pcm was first used pcm masks any potential problem no tell tale glitchs as with ppm just a sudden lock out

No one talks about the programming features wich is were the DX-7 and 9303 really have an advantage over comparable futabas. The spectrum lockout problem has had fixes also, especially with the new quick connect feature. Notice most of the voltage lockout problems have been with electrics wich are probabley using inseficient ESC/BEC combo's. Spectrum has been on the market longer. There are many more spectrum transmitters in service. Spectrum uses 2 recievers and 4 antenas.

I have had a minor lockout and a nasty one in my 27% cap not resulting in a crash. I am still convinced I solved the problem. Either the AR6200 couldn't handle all the loads or the signal was bad. The batteries were dual 6v in parallel. But this plane has a huge gasoline engine, 3 batteries, 3 switches, ignition module, 2 mathboxes, a huge fuel tank, and 7 serovs. I am hoping by eliminating the ar 6200 and mathboxes from the picture and installing an ar7000 with a 24inch sateline extentsion I will be in good shape.

right... but they have made an annoncement, and that is the sole problem, as far as i know...

daggets

i had lock out too, but i ve tried many different batteries, 4.8 volts and 6 volts, it has remain the same....
i ve tried 2 differents receivers, same... the plane is a simple curare with 6 simple servos...
i ve tried the spectrum in another airplane, a calypso, simple, 5 servos... same....lock out 2 or three times a flight.... , no radio for 4 seconds each time, but no crash...
if someone can explain that to me, i will use my spectrum again...
as you have noticed, i feel concerned by this issue...

Simply amazing--
the Curare - 30 year old design
Calypso- almost the same
Simple servos 20-30 years old?
simple batteries 20 30 years old? .
You paint a picture of rather old equipment being your choice.
Multiple lock outs are NOT a common thing with Spektrum-for that matter
not a common profile for ANY flying I do -or know of -
The low voltage "lockout "alert (the blinking light" will alert ANYONE to a voltage problem
IF lockouts still occur-then you are looking at signal loss.
Frankly Your "stories" don't reveal any reasonable approach to determining whether or not the rx is a cause of the "problem" you comment upon.

daggets

but no... i m a vintage pattern flyer.... the design is 30 years old... all the stuff is new!!!!! even the balsa! the plane has been equipped with all the spectrum combo stuff!!!

see?

So - we are down to the multiple lockout thing
Assuming you do have dual rx 7000 and rx are spaced well and the batteries are NOT falling below 3.5 -you are describing a signal loss - complete- for 3--4 seconds - I simply have never seen this.

I see this thread has sadly headed in the expected direction... [] The question of which is better -- Futaba FASST or JR/Spektrum DSM2 brings out the same level of incivility as asking here is the US: "Who is better -- Democrats or Republicans?" Since we are all true believers in our radio (and political party) we are going to defend this choice no matter how silly or irrational that defense may be... After all -- there is no 100% perfect radio (or political party).

To the thread starter -- buy the one that you think best suits your needs and budget and enjoy it! There are real differences in the two product lines beyond the SS implemetation that are more complelling and interesting.

Now back to the regularly scheduled brand wars... [:@]

Actually, the thread was fine until this comment was made:

Before that, everyone gave pretty much the same answer--that being both are good systems and work fine. If Spektrum didn't work, nobody would buy it. If FAAST didn't work, nobody would buy it either. You can nit-pick all day about the differences in each system, both work--but in different ways.

daggets

believe and you ll be saved.... amen

you know, in france , we have the renault cars, they does not work, some people buy them,

i believe in god, but for technology, i want to understand...

i don t see what politics have to do with it either...

i m not a new modeller, you could accept that what i have experienced is true... instead of making a brand war where there is a fact: read the thread i gave ...

to answer to dick, i have never seen you, but i know you exist....

and i can affirm, a mercedes is better than a renault, not because of the brand, but for technical reasons....

peace and understanding.....

buy what you are comfortable with using.
If there was much credibility to the horror stories related here -none of the equipment would be in use .

Never said you were making it up or had no experience--but when you say that one system flat out doesn't work--you should expect the types of reactions you got.

daggets

so what is the purpose of the forum? if you must say everything is the same, if you must keep your opinion for yourself, and encounter unique thinking terrorists fighters?

if you cannot even ask what is actually best, outside of the commercial influence?

explain me, with real reasonment, i want to understand...

rmh

Your opinion, is your opinion-
Your problems with Spektrum- are simply unknown to me -
Apparantly -you claim you operate in an enviroment which the Spektrum will not tolerate .
If the factory people have no help for you on this -I have no suggestions
Isimply have no "enviroments" here which will cause problems such as you describe.

daggets

i ll try the quick connect and let you know...

Just to add to the knowledge base, On my flying site we have a problem with high energy microwave/transmission towers communicating over an estury, the field is flat with no towers in sight we just know they are there from the Ordanance Survey Maps.

PPM has issues with glitches in certain areas of the flight line.
PCM has no issues does not go to lockout or fail safe, one instance of glitching into the ground on one plane, mine unfortunatly, possibly a frayed wire discovered on post mortum.
Xtreme/Graupner IFS 2.4Ghz system, lots of lock out in the normal PPM interferance areas, my plane again only just managed to save it.
Futaba 2.4Ghz system no in flight problems encountered on this site, some ground problems with non binding and not working until switch off and on again.
Spetrum DX7 no issues of any kind over 100 flights.
Futaba with Spektrum module no problems of any kind encountered.

These are just my finding on my site, make up your own mind.

I now fly only Spektrum equiped Futaba and Spektrum DX7 on this site, anything else is just to exciting an at my age excitment is to exhausting.

Mike,
You say: "I now fly only Spektrum equiped Futaba..."
Does this mean you fly Spektrum transmitter and receiver with Futaba servos?
Regards
JC

larshkj

He probably means Futaba radio with Spectrum module and receiver.

Futaba with Spektrum module no problems of any kind encountered.
