Anwar Bhai you are quoting something which was said more than an year back!

I don't think that's true. I am using DSM2 since more than an year and there are no reliability issues.

Ah.. the radio wars again    

There are long threads here on this subject.  I am a Futaba user, so consider my take on this biased !

The simple fact is that DSM2 was replaced by DSMX.  The question is why ?  There are literally thousands of people who are happy with DSM2, without a facing any problems in many many years.  Yet, Spektrum changed the standard.  The reason, from what I could gather, is that there are indeed deficiencies in the DSM2 design that causes issues in overcrowded gatherings. DSM2 also seems to have a higher share of "unexplained" crashes/lockouts/whatever.  If you want to get more information, just search the US forums like RCG.

From an RF link stability perspective, probably Sanwa/Airtronics is the highest rated.  For multiple reasons (one of which is lack of proper marketing), it did not catch as well as it should have.  Futaba's FASST system has also stayed the same from day one, and is also considered a very very robust link (although they had other problems like some receivers being affected by heat, which was noticed and fixed couple of years ago).

These days, all 3 of these are similar (Airtronics, Futaba FASST and Spektrum DSMX).  Make your purchase decision based on features that are useful to you, cost of the system and availability. If I were to get a radio now, I would probably be torn between Futaba and Spektrum.  I am not that excited about Airtronics for only the reason that it never gained critical mass (which is not really a valid reason when you think about it, but does have implications on the field and in terms of resale value).

That is because Mohan bhai +1ed it today (see Reply #46).  That +1 is what I should have quoted, as that does not seem to hold true any more.

Don't know sir, but all the polls i have seen conclude otherwise

http://www.helifreak.com/showthread.php?t=194243

Out of 111 users, 77 are DSM2 and 26 are FASST.
In that, 5% DSM2 users have experienced failures and 7% FASST users have experienced failures.

Many polls are misleading. Search for "unexplained crashes" on Google with the different brands, and read the threads from the various forums.  More importantly, there was a time when FASST had temperature issues plus a duplicate ZGUID issue, so polls from those times may indicate that.  What you need to look for is the actual reason for problems, and when you take out issues like manufacturing issues in particular batches etc (the ZGUID and temperature issues for Futaba etc), you will see that DSM2 has more unexplained crashes than FASST. 

Here is a post by Sushil bhai (sushil_anand), who has also come to the same conclusion :

The fact that DSM2 had to be changed into a frequency hopping system (DSMX) itself proves the superiority of such FHSS systems (or hybrid FHSS systems, rather).  Both Airtronics and FASST have been freq hopping systems from day one.

My vote goes to Turnigy

Not trying to start another radio war but the high number of people using Spektrum radios is due to the influx of all those micro and bind and fly (BNF) models in the US which sometime come with a Spektrum as RTF or can only be flown with a Spektrum (BNF). A good marketing strategy on the Horizon Hobby part so most beginners begin with a Spektrum radio. I fly at busy flying fields and have seen many "unexplained crashes" and have seen many people moving away from the DSM2/DMSX when they advance in the hobby.

69.37% have voted "I fly Spektrum/JR DSM2 and have had no failure"
It was a poll about radio failures and not about which brand has maximum users

hey hi!u live in anand?where?m too from anand

Turnigy 9X 9Ch Transmitter w/ Module & 8ch Receiver (Mode 2)

I would pick a spectrum

My Vote goes to Flysky 9x Radio 

I have an Old JR..... guess the age... its 22 yrs old a 7 ch FM Set.  Survived plenty of crashes but gave no glitches.  Now I am looking to change to a budget stuff... Guess my choice is going to be Fly Sky ( ch or Orange 6 ch from HK

well my vote is for Futaba ....always..

E-Fly 2.4 Ghz,  4 channel.

Going with my Turnigy 9XV2.... It has been with me for over two years and is working without glitches.

I think we should add the Avionics Radio too in the list, as its missing.

i am planning to buy a transmitter which is having the longest range(i mean to say is any radio available to operate in 4, 8 ,or 12 km of diameter ) so which  transmitter to buy   

I just got my Taranis X9D+ and it's too awesome to resist. Being a developer / designer, the open source framework is just too good!!!!!! Will post more with videos once I can figure it out myself!!!

i was on Futaba 72Mhz, now Airtronics 2.4Ghz and Hitec Gen2 2.4Ghz 

Well I used to have Flysky TH-9x then sold it but it was a Good Radio. But I See 74 % of the People Are using HK/KDS/FrSKY/Turnigy 2.4Ghz etc.
And then comes Futaba In Line.
Regards,
Aman.

@aman1256,
74%?
No.
74 out of 262.
Or 28%!

Oops sorry.

avionic 2.4 ghz

What about home  made ones  ?
