Geoff,

I certainly would agree there is very little to lose on the DX5 at that price.

Im just dissapointed that the solution seems to be use a very simple controller where you need one tx per model or use a very expensive receiver.

It hasnt really fixed the ongoing problems which probably means that they dont know what the problem is. This then means that future releases, particularly in the short term are IMO suspect until they either fix it or release a DSM2 bot receiver.

Andy ...The AR500 is a DSM2 receiver and appears to meet our requirements on the failsafe issue.

Well Woody, knowing that would require reading what you had written rather than holding a grudge wouldnt it????

Anyway, just to pour a bit more cold water on it, I spent today playing about with Antweights. Using the DX6i and the AR6100 receiver (a DSM2 rceiver) I was able to recreate quite readily the problem with loosing the bind.

I think as Peter Waller said, the BR6000 connection is very slow and haphazard. With the AR6100 its quick and easy. My set up had a 11.1V 300mAH LiPo and a 2x5 Sabertooth with some Sanyo motors. The set up works fine until you push the sticks to the exterme. When you do this the rx drops out and loses its bind. As I said before, I think this is a BEC problem as it only ever happens on the extremes and its a bit more noticable where it happens when the failsafes dont kick in on all channels. Ill try it with a voltage regulator and see what happens when I get back to London.

I know the DX6i has connection problems with the BR6000. I would say that just because its a DSM2 receiver doesnt mean it will be without its problems. From a pesonal point of view, I can see all our bots going with either voltae regulators or seperate rx batteries.

Another thing Luke pointed out today is that Hydra does this too. This is with the DX6 and BR6000.

So it seems that from ourDX6i working ok with a slight connection problem, weve gone full circle to everything not working properly!

Sorry, duplicate post, seems my internet keeps dropping in and out.

Damned wifi hotspots!!

Andy,
As a team we have always used seperate voltage regulators or RX batts.
3 reasons...
1 our machines have remote kill devices in them that remove the supply from the speed controllers so therefore cant use the on-board BEC.
2, I wouldnt trust any speed controller BEC to deliver moere than 100ma reliably and as a DSM1 or 2 RX can easly draw 120ma+ a seperate supply is a must.
and 3, it stops the problem you have described above

Personaly I dont see a problem with using a seperate RX power source, we use these in all our machines

For the 36V bots, can you connect the input in series and the output in parallel (Max voltage is 33.6V input) or would this kill them?

I also dont see a problem with using a seperate power supply in heavies and feathers. After all it is only another 5-10g bit more of an issue in an ant though.

The problem your experiencing is purely not having enough power in your receiver supply to do the job - this is by no means a problem with the receivers and has been known since spektrum receivers were being used. As geoff said, you should always use a seperate battery pack or BEC to make sure these problems dont occur unless you can guarentee that the built in BEC on the speedcontroller will supply the current.
If your having problems when running a seperate BEC thats rated for the job, then you are REALLY over stressing your battery packs with the drive motors.

Grudge Andy?...Im confused by the first part your post.
If Ive offended apologies.
It is never my intent to tick anyone off.

Not against you Woody. Im just having a sulk at Spektrum mate, throwing toys out of pram and all that.

Grant,

As with all these issues, only known to those people around at the time and party to the discussion. Steep learning curve with all these things for someone newish to this.

Bear with me a little as I obviously have some catching up to do.

Does the DX5 not bind to more than 1 RX (IE: I cant use 2 bots on the same TX) ?

[woody]

The DX5 is just a cheap 5 channel no frills version of the DX6i....I see no reason to treat it any differently.
