The heatshrink isn't conductive as such with regards to the RF. The dielectric properties of the heatshrink is what is playing the part here. It has the effect of detuning the aerial slightly to a lower frequency. I have checked out the effect with black and clear heatshrink and they both give the s...

Bearing in mind that the Taranis is really designed for thumb flyers, rather than the more precise pinch method flyers that we have in Europe who tend to prefer tray tray format transmitters that lend themselves to additional switches/pots or whatever on stick ends.. Which leads me to suspect that w...

Flaps 30, have you tested these: http://www.alofthobbies.com/40cm-receiver-antenna.html. Also available in 25cm and 60cm lengths. They appear to be sleeve dipole. I have a set but haven't installed them yet. No I haven't tested them. It looks like it is the sleeve dipole as you say or what Hitec lo...

I missed this post, it's really hard for me to read all forums, please open issues, it takes only one minute and it helps a lot on project management side, thanks! Will do. Before that I will try and see how I can describe the problem with the curves, as to what they are doing at present, along wit...

Nightly builds for each platform including m128 have been built automatically every night for about a month before release, precisely so that people could test without a development environment... was of course announced on the related thread that went on top of the recent threads several times eve...

I make them. Yes they are easy to make using the stock antenna. Bill - The 29mm worked fairly well and it did look better than the 28 odd millimetres that I have for most of my aerials. Hence why I suggested it. All that I have made have been measured/adjusted using an SWR meter along with doing a r...

I haven't seen the aerial/antennas of the D8R-XP. Assuming they are the same as the D8R with it's 33mm 'whiskers', then I can say that I have got up to 1500 feet with minor blips on the telemetry. My first change was to reduce the whisker from what will be around 33mm to 29mm, which improved the sig...

I find my self somewhat amazed at the gall of the throngs emerging from their caves to throw stones at the fatted calf when they never lifted a finger to evaluate and give suggestions prior to it's release. I would have loved to help with testing out the stock M128 version before it was released as...

Fix worked a treat.. Thank you.. :) Tested the Skysurfer file again. Found that the curve values had all changed to way out figures, along with most of them were converted from three point to five point curves. After setting them to what they should have been I was unable to get it all working as it...

Thanks.. I did check with companion to see if the same problem existed with the other transmitters. I could get the same problem to occur with all of them with the exception of the Taranis.

Looking forward to the update.

The use of logical switches in the way specified happens on a few channels. Probably the best one to look at would be the model 'Skysurfer' and the use of L8 on channel 6 which should cause the output of channel 6 to switch between -100 and +100 every second.

Tried out 2.0 today after setting up the profile set for a 9X board fitted with an M128.. It seems that it doesn't like logical switches being used as channel sources, as nothing happens when the logical switch changes state. Checked to see if the same applied with the 9XR and it reacts in the same ...

This is getting a bit confusing. This thread was all about pre-release problems, yet it is still being used to bring up matters concerning the official release. Trying to follow things on two threads that is about the same thing (as of the release of 2.0) is giving me a headache. Not good!

Try to keep the receiver aerials away from the servos and any other wiring. As for the receiver/servo interaction. Assuming that the aerials are nowhere near the servo, you could try some aluminium foil between the receiver and the servo.

Those balloon pilots are nuts,. Well yes. Anyone that gets up before dawn to just spend a short time in the air before the thermal activity starts must be nuts. They do fly in the late afternoon/early evenings for the same reason mentioned earlier. Of course you do get a few pilots (generally in fa...

Mike - Yes that would do it. The divider on the bipolar version was the cause of the changes. Given that there is now an FET in place now, it would be possible to add a high value divider as the input Z of the FET is high. It's just that I have a lot (like a couple of hundred) BS270's in my junk box...

Further work was done on Skynorth's original idea. My initial changes worked fairly well, other than when the LED was changed to a high brightness one I could see a dim glow from it. So the change was to remove two resistors and the bipolar transistor, replacing then with a nice FET. The FET used (B...

As you say, It is when something will happen that makes the news big time. The CAA in the UK allow FPV flying under strict rules. So far one person has been prosecuted and fined a large sum in the UK for breaching the said ANO. The CAA have recently increased the weight limit to 3.5Kg along with inc...

It would be a good idea if you could give us a picture of the area that this component is in..

I'm running OpenTx on the 9X fitted with an M128 chip. Templates are available on a menu page offering a basic four channel setup along with many others. Yes it also has a V tail and a Delta template.

I would have thought that what is there would be a adequate for the beginner.

Ouch! Sure looks like a mess to me. With hindsight you might have been better off buying a Turnigy 9XR from Hobbyking or investing on the solderless programming board from Smartieparts. But that doesn't help you at the present does it? I had to take out my jump lead to solder in the new 220v resisto...

I can't believe what I'm seeing here talk about complications a toggle switch and a resistor (if that) will reliably do the job, and indicate if its on or off by its position, That would spoil the fun of doing this. :) You could add another push button between the SCR gate and ground, so you could ...

Is this with the standard receiver/transmitter setup?

I had some time today so I used it to smash together Skynorth's circuit with a few changes incorporated. It does work with voltages down to 4.5Volts and up to (and beyond) 6 Volts. Here is the revised circuit. ESC_Safe Mod.JPG The above was tested with a couple of SCR's that were lurking in the junk...

Very nice. :) Almost orgasmic over that.. Most of what I see is good. No nasty sharp pointy bits on the ends of sticks. Having the ability to swivel the stick assemblies, transmitter battery management: display, single cell battery pack. I also liked the side mounted controls that could be adjusted ...

What's a part number for the scr? I can try the circuit and see what happens I would have thought that any low power SCR would do the job. My junk box has a variety of TO92 canned SCR's hiding in it. Looking at the circuit the value of R4 (1K Ohm) in Skynorth's circuit seems a bit on the high side,...

Never mind Rob. Give it another few years and then you can wheel the harmonic along to the show as a birthday treat. :) How cold is cold how wet is wet? Cold is when the temperature drops to 13°C inclusive of the wind chill factor. Wet is like any more than a very light drizzle. Since we all are ano...

I should be there if it isn't too cold or wet..

Anyone else?

What does the value actually mean when compared to the Standing Wave Ratio?

Personally I find return loss is more useful (comes from my video days) ---> http://en.wikipedia.org/wiki/Return_loss

I have seen that sort of stuff before in some Pye radio equipment many moons ago. No idea what it is.. Normally U.fl connectors are very secure if fitted correctly. Having said that. I have had one instance on a DJT TX module where the connector wasn't secure and no glue was used, and that lead to a...
