After a s107g will it be a Msr or Msrx??

[Karlo]

Hi all, started back into the helicopter and want to sit it right.
i can hover and land the s107g quite good now and was wondering what's the next stage from there?
i am thinking of the one of the two above but which one is the better one or is one just an updated version of the other ?
would like to mainly fly indoors but soon have an option to fly both in and outdoor by getting a blade 120sr weather permits.
hopefully that is the right way to go..
thanks all
any more information required please ask.

Karlo. The mSRx is the Flybarless version of the mSR and will the the perfect step-up from the 107. There are numerous threads on 'what next' or 'first step' and most give a thumbs up to the mSRx. Although very robust there's a little less to get broken on the mSRx compared to the mSR so go for that version. You won't go wrong in acquiring a Spektrum DX6i transmitter either. That will see you through your next few upgrades and will allow you to tame the mSRx for its first few flights.

See you here in a couple of months when you next want to upgrade :-)

Thanks for advise.. I have been reading this section and there are a few that comes to mind that are recommended.

On the hunt for a Msrx rtf unless I can find a decent dx6i for sale than it will be the Msrx model only. Just Incase I don't carry on. Being honest here

[tomatwalden]

The rtf msrx is usually pretty cheap new. Check out www.rcferret.co.uk to find the best deal.

[Karlo]

Thanks mate. Been looking at that rcferret from one of the threads I have read and still debating whether to spend £40 for a Bnf and try for a second hand dx6i for long term or just spend the 65 for the rtf.
i am right in saying you only need the transmitter as the original receiver in the Msrx will bind with it?
dont think it's the same with my dx3, cannot remember

so, if you buy a second hand DX6i, the msrx will indeed bind with it no problem. Also, you will find learning MUCH easier as the RTF msrx comes with a very basic transmitter which ultimately is something you will quickly junk if you get hooked on this hobby.

So, I guess it depends. If you're still trying to decide if this hobby is for you, then the RTF represents an easy, all-in-the-box, guaranteed working from the start, nice intro. If you already think you have the bug, then the DX6i route is definitely better - and will be cheaper overall (quite quickly in fact, within a few months).

EDIT : If you do buy a second hand DX6i - make sure it's one of the later DSMX compatible models, not the earlier DSM2-only variant.

Thanks again Tom,
just been doing searches on the forum and trying to read the relevant posts....there are tons of knowledge as long as you read the right threads from start to finish...lol
i wish I did not sell my dx6 back in the day I first tried RC helicopter and gave up as I could just about hover and that was it...but I did start with the totally wrong helicopter I believe...

p.s. Thanks for the heads up on the dx6i. Noticed that most are dsm2

[Euclid]

Tom, I've a DX6i I'm selling, how do you tell if it is the earlier or later version please (it has bound without any problems to a mSRx, Nano and a 130x).

Karlo, whereabouts are you based?

[Karlo]

Hi I am based in the Lancaster, North west

Simple! It has a DSMX logo to the right of the screen .. eg. http://www.rcpitstop.co.uk/ekmps/sho...nly-1505-p.jpg

(earlier version looked like this : http://www.rcslot.com/blog/wp-conten.../SPM6600-2.jpg)

To be honest, DSMX doesn't make it work with any more or any less helicopters. A DSM2 version will bind with all the same helis as a DSMX version since all DSMX receivers are backwards-compatible with DSM2 transmitters. It's just that DSMX is more reliable when lots (read tens, if not hundreds) are all flying in close proximity on 2.4Ghz. In essence, the spread-spectrum frequency hopping algorithm is better.

If its a Dx6i it will bind to both DSM2 and DSMX they are backwards and forwards compatible. If its an Old style dx6(no i )it will be DSM which is standalone. And just to complicate matters the new DX6 has no i (if you use crossed technology the protocol used reverts to DSM2)

the picture you linked to Tom is a DX6i which will work with DSMX.

this is the original DX6 that is stand alone and incompatible. with DSM2 and DSMX

[tomatwalden]

... the picture you linked to Tom is a DX6i which will work with DSMX.

Not all will Ron! Spektrum released two different DX6i's - although they never really publised the fact. The "generation 1" DX6i was DSM2 protocol only. The "generation 2" DX6i was DSMX capable. The two photos I linked to are both DX6i's. One is the newer DSMX version, the second is the older DSM2 only version.

As you say, the (really new) DX6 (no i) is DSMX too - I personally wasn't aware of the very early (pre DX6i) DX6!

To hopefully clarify things. The communications protocol used by all Blade micros (and many full size receivers) is DSM(x or 2). DSMX is the better one Thankfully all DSMX receivers or transmitters can talk DSM2. So for example, a DSMX transmitter can talk to a DSM2 receiver (but only using DSM2 protocol - ie. the transmitter uses the older protocol). Equally, a DSMX receiver can talk to a DSM2 transmitter - but again, the receiver will "dumb down" to use the older DSM2 protocol.

No DSM2 only system (RX or TX) will "magically" talk DSMx if bound to a DSMx counterpart.

[Boggy]

Never heard of that before and certainly not what Horizon say.

Is DSM2 and DSMX equipment compatible?

Yes! DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they're using DSM2 equipment, DSMX equipment or a combination of both.
It is important to note, however, that the only way to experience the full benefits of DSMX (wideband DSSS plus frequency agility) is by pairing a DSMX transmitter with a DSMX receiver.

Spektrum: Additions to DSM2 that makes DSMX

[tomatwalden]

Nah, HH are just using confusing language. They are saying transmitter (DSMX) to receiver (DSM2) is backwards compatible, whereas receiver (DSM2) to transmitter (DSMX) is forwards compatible.

In reality, they are using bad terminology by confusing TX->RX and RX->TX with forwards/backwards.

Fundamentally, ignoring TX/RX direction, and focussing solely on the protocol, DSMX and DSM2 are completely incompatible!

However, all DSMX RX's and TX's are capable of talking DSM2. So, when presented with an older counterpart - everything still works. (everyone just switches to the older protocol)

Hence the statement "t is important to note, however, that the only way to experience the full benefits of DSMX (wideband DSSS plus frequency agility) is by pairing a DSMX transmitter with a DSMX receiver"
