Hi Scottie,

Glad to hear you've finally got your mits on yer DX-6. I assume your set came with rechargeable cells. Ive been reading a US forum that states that the cells included are only 600ma. As you are aware current drain is 260 ish mA so only expect a couple of hours use.

On the up side, Ive done the mod. to the regulator (see previous posts in this thread for details) on my set.

As you'll see from the photos on this post that it does make a difference.

Things to bear in mind :-

A modification like this will almost certainly make any warranty void. If youre not confident with the modification then STOP now.
2 regulators are available. Make sure you purchase the 3.3 volt type and NOT the 5 volt version.
There are other components close to the regulator and care must be taken not to disturb these.
There is a temptation to fit the new regulator with the writing facing out as with the old regulator. This is not correct as the writing on the new regulator must be facing inwards.
The old regulator's metal back is soldered to the board so a hot iron is required to remove this. I used a 35watt iron just for this task and a smaller iron for the connections.

Finally,  just when we thought we had the latest technology, theres now a DX 7. Main differences seem to be:-

7 channel instead of 6 (Obvious)
Greater range designed for larger scale aircraft (Or any other model for that matter)

Good news is that DX 6 receiver (AR6000) is compatable with new DX 7.

Further info from :- http://www.horizonhobby.com/Articles/Article.aspx?ArticleID=1626

Have fun with your new set scottie.

Thanks for the PM Terry, I missed your last post somehow (Notify failed I think).

Nice to hear you've done the mod without trouble, I'll have to order one of them regs.

A bit more information that might be of interest, especially for sub builders/sailors. There's also a new receiver out BR6000 (I think) - 6 chan but with this one all six channels can be set with fail-safe positions, not just the throttle. There's a US site that's offering FREE swap for your old AR6000, I wonder if they'll do it free for Uk residents (doubt it).
The site is about robots, not aircraft or boats. If interested I'll see if I can find it again.

Thanks for the info Scottie, but I'm happy with my AR6000 although, it's ideal for a sub skipper.

Have you found any problems with your set ?

Hi Terry,

No problems as yet but I didn't have time to set it up last weekend. First trial this weekend right after I've tried a new brushless motor in a club 500 type huill. I've given this a trial in the bath and looks like it'll go like stink.

Finally got to make a test of the Spektrum DX6 radio gear.

First, I've been having interference problems with my pusher tug, tried 3 different crystals but couldn't get any improvement, we seem to have a 'dead' spot on our lake but this only affects the tug. So I put the 2.4Ghz system in and gave it a quick run, obsolutely no problems whatsoever. I haven't done a range test yet, the weather was too bad for that.

I am very happy with the new radio, it does exactly what it says on the box.

Hi Scottie,

Glad you got to try your set out although if the weather here in the midlands was anything to go by you probably werent out too long.

Its worth sitting down with your set in the workshop and sorting out all the mixing/adjustment options.

Ive finally installed mine set in my lastest model (Slipway's Vliestroom) which has a bow thruster.  Using the set I can mix bow thruster with rudder and even switch the mix in and out at will. (Very useful)  Also the mix ratio can be altered to suit.  All without the use of any extra pieces of kit.

When I first got the set I found that the servos didnt seem to travel as far as other radio sets but this was soon sorted out by setting all channels to 150% throw which actually gave me more travel.

The only problem I found was that the 2 Mtroniks speed controllers didnt recognise the 150% forward signal as the sc switched off when throttle lever moved to full throttle. This was soon sorted out by making full throttle 125%.

All is now ok.

Im just waiting for some decent weather so I can do some ballasting before its maiden voyage in the sping.

 can anyone tell me if these Spektrums can only use their own servos - the ones that come with the transmitter seem to be micro size ; whereas the ones that come with the DX7 seem a lot chunkier

Rats, my set is driving a standard Futaba S3003 servo without any problems. I haven't loaded the receiver with six of them yet but I can't see any reason why they shouldn't work okay.

 thanks Scottie - just as a matter of interest can you see any advantage in the DX7 over the DX6 other than the extra channel
 reading between the lines on their website the DX7 seems to have a greater range (power) , so im not sure if it would be legal over here . It does have better servos and extra channel though and costs about £100 more . Im determined to get one or the other but haven't even seen one - living in the sticks !

Thanks for the comment "...can also be used in France..." I was wondering about that as I have seen none of these radios offered for sale here, as yet.

However, I shall be staying with my Navy F-14 for now as it is such a good and flexible set up with ample opportunities to extend the number of channels.

Hi Guys,

The following quote has been taken from the UKRCC site http://www.ukrcc.org/

Quote
News from Ofcom - "The regulations allowing the use of 2.4GHz Wideband Data Transmission Systems at 100mW will come into force on 8th December 2006."
.

This now covers  Spektrum DX6 Transmitter. (Prevoiusly max was only 10mW).
Dont know the power output of DX7 but may be greater than 100mW. (Any info would you useful).

Also the earlier post about CE stickers is still valid.

Cheers all,  ;)

Terry.

Just found this link on the Large Model Association web page when looking for something else! It appears that the max power allowed for 2.4 Ghz sets has been raised to 100mW

Hi Guys,

As any owner of a Spektrum 2.4 ghz Tx will tell you, there is a lithium battery hidden away inside the set which will result in the reset of all data within the set, back to the factory defaults once its power has faded to nothing after approx 5 years.  According to the manufacturers booklet, this involves returning set to them for battery replacement (currently USA) no doubt at quite a cost.

Whilst modifying the battery connections on my DX6 I decided to locate this battery for future reference as its not obvious where it is.

Photo 1. Remove 6 screws from back plate and remove back of set.

Photo 2 . Remove 4 screws holding top circuit board in place and swing board out of the way. (Note mod. to voltage regulator can be seen as described earlier in this thread)

Photo 3. Remove 4 screws holding lower board in place and lift  right hand side gently.

Photo 4 Battery is located under the lower board on right hand side (Can be seen through mirror).

The battery number is CR2032 which cost around £1.00 each.

It should be possible to change the lithium battery and retain data as long as main tx battery is connected as the lithium cell acts as a back up.

Terry.

PS. Ohhhh, Im now a CPO.  Never felt a thing. ;D

rats,

Could you be a litlle more specific on what you want the set to do.

Ive managed to mix the bowthruster with rudder using my DX 6 ok.
