Thread: Spektrum Radio repairs ?
19/03/2019 18:40:43

I've heard separately that Logic RC and Nexus models handle Spectrum repairs. I'd give them both a call and see what they have to say.

Tim no I'm using Android so that answers that.

I see it is available in apple App Store.

It isn't, in Android Play store so maybe it is new for Android, and not ready yet?

As you can see from my screenshots all the S6R/S8R stuff is there.

Good news, well done Allan

Yes, in my opinion it will be much more useful if they ever make the dashboard customisable like the Horus telemetry screens are.

This afternoon I've failed to communicate with an S6R using this via the Horus. Maybe that just works via an airlink S ?

OK thanks Tim

I was trying to get Power and mAh to show on dashboard but have failed so far.

17/03/2019 12:18:43

Sounds good Tim.

I'm still not sure of the advantage of displaying things on a separate screen when they can all be seen on the Horus one anyway, but I'm ready to be convinced.

Did you manage to arrange the parameters you wanted into the dashboard screen? If so, how?

17/03/2019 11:35:36

Ron it appears to be early days. It looks like all X receivers.

Probably most useful for setting up things like stabilisers. I'm not sure how I'd use a live telemetry unit on a separate screen. Unless a spitter carried it so he can see readings?

It can be connected via transmitters that have Bluetooth i.e. those that support wireless buddy .

Or, it can be connected via an S.Port airlink S.

I haven't seen it available in the android play store so had to download, unzip and install manually from here

17/03/2019 11:26:11

There appears to be a new app available for your smartphone or tablet.

Here's a quick preview of screens from my phone.









Thread: Seagull 80" DH Chipmunk
16/03/2019 18:08:07

I now have a wing tube with an acceptable fit. Thanks to some suggestions here and some perseverance.

The ally tube has been smoothed with 600 wet n dry used wet, especially at the ends to be absolutely sure there's no burr.

But the most difference has been made by making my sanding tube a tighter fit. This is 120 grit aluminium oxide paper wrapped until it's a tight fit inside the wing. Obviously this applies more "sanding pressure" than previous attempts.

Thread: How to reduce voltage?
16/03/2019 15:33:19

How much current do you need at 12v Gary?

Have a search for things like "12V regulator" or 12V regulator module.

Here's an example.

Edit - Possibly not the best example as the text warns to keep current below 0.8A

Thread: Seagull 80" DH Chipmunk
16/03/2019 14:48:52

Hi Ron. It is indeed an implementation of OpenXSensor. There's an article coming up soon in RCM&E. I'm intending to have a proper thread on it here, as soon as it's published.

Danny. One quick look at that screen shot above and I see a programming mistake. Somehow we've ended up with some flap compensation with the wrong source. The + line just below CH3 is adding to the elevator, but it's sourced from rudder! Thankfully the amount is zero % so it will have no effect.

Needs fixing though.

Thread: Smart tv
12/03/2019 23:23:32

If you use HDMI then it probably has to be connected, as Adrian alluded to, to an HDMI socket that has ARC. It's likely that only one of the HDMIs on the TV has this so you may have to try them all and/or you may have to enable ARC.

(ARC means Audio Return Channel. Intended for sending audio from a TV "back" to say a Blue Ray player / surround sound system which would usually be "sending" signals to a TV).

If you're really lucky this link might even turn your soundbar on and off automatically too.

Thread: Does anybody know how to fix this?
10/03/2019 17:20:04

Chaps the OP wasn't a question about how it happened or who to blame, just simply - how to go about putting it right.

Can we stay on topic please?

Thread: Buddie's build thread

Hi Peter, welcome to the forum and to the mass build.

That looks like a spring has popped off or is broken. Pop the back off and see what you can see.

Thread: Arduino project - Servo Exerciser - RCM&E Dec 2018
09/03/2019 17:40:46

OK yep I agree with you thinking. Hope you can get the scope going.

09/03/2019 16:27:12

Steve that's all very interesting.

I think that the reason some servos might not respond would be due to the signal pulses only being 3.3V.

I thought this would be OK because (I thought) most modern receivers do exactly the same.

It would be interesting to try the 5V version of the Arduino to see if they would respond to that, I'm sure they would. Or maybe try something like this to boost the signal.

Mm very good point Bob.
