Thread: FrSky Taranis - user chat
25/11/2019 11:13:20

On the X9Lite with the ACCESS module, the EU/non-EU mode is set simply by running a script to change the mode, the module doesn't need re-flashing. You may need to enquire about getting a script to run on your Tx.

My understanding of the ACCESS protocol is the Rx (running ACCESS of course) automatically detect the EU/non-EU mode when binding.

Thread: Jumper T16 is it me ?
24/11/2019 10:17:41

Assuming you are using the multi-protocol module on the T16, this has most likely got automatic channel re-mapping in it. What this means is you (always) set the Tx to AETR. The module then changes this order depending on the protocol it is using. For Spektrum (and compatibles) this is TAER.

So, with the Tx set to AETR, you should find the throttle is output on channel 1 of the Rx, Aileron on 2, Elevator on 3 and Rudder on 4.

Try this **LINK**

I just did a search for
"top gun" rc 2.4GHz transmitter manual

Looks like it binds on every power up!

Thread: Horus X10 Express

There is a video how-to here: **LINK**

However, you might like to consider the following. With the radio powered off, if you connect it to your computer via USB, the processor will start in "STM Bootloader" mode. In this mode, you are able to read the flash memory from the processor and write to it. Reading it means you should be able to restore it if something goes wrong during the update.
To use the STM Bootloader, you need a DFU (Device Firmware Update) program. STM provide one called DfUse. You may download DfUse from STM here: **LINK**
It looks to be available from other sites as well (DfUse Demo works fine). I read the flash memory from my X10S Express using this only a couple of days ago!

Thread: RX8R Pro Signal Swamping??
16/11/2019 10:25:17

The new ACCESS capable modules (built in and external) include support for 'X' series receivers (D16 protocol).

If you have older D8 receivers, I've written firmware for them that operates in D16 mode, see here: **LINK**

RapidRc appear to have a combo for £44.99 (DFT + V8FR-II) see: **LINK**

While needing a bit more effort to fit, the DHT will work.

The DFT (and DHT) are now listed on the FrSky site as discontinued.

Thread: Boddo's Biggles Biplane
21/10/2019 16:22:37

I read "Biggles learns to fly", but I think my paperback copy is no more, although I have a number of other paperback Biggles books. I do have hardback copies of " "Biggles Pioneer air Fighter", "Biggles of 266" and "Biggles of the Camel Squadron".

I don't have anything to compare it with, but I found the Cessna 150 quite easy to fly, I did my first solo on one!

Did Biggles ever fly a BE2, maybe he did very early on? As I remember, he flew FE2s when first posted to the front.

Was that first book "Biggles learns to fly"?

What problem with programming the Neuron did/do you have?

Mike

My most recent electrification is a 60" span aerobatic model. I'm using a FrSky Neuron ESC with 8A, switch mode BEC. The BEC output voltage is programmable up to 8V. I'm using 4S lipo (two off 3000mAh in parallel). Since I use a FrSky Tx, I get all the telemetry data from the ESC (flight pack voltage and current, ESC temperature, RPM, and BEC voltage). It also has a programmable current limit.

I think the Ripmax Quantum 55 is the same motor, have a look at pictures of it and see if it matches.

Thread: Jumper 4in1 module problem
08/10/2019 19:32:40

I just tried a jumper module. Set the dial to 15, then power on. After various red LED flashing is settles to a single flash periodically. Pressing the bind button, changes this to two flashes periodically, pressing again, changes to three flashes and so on up to 5 flashes, then back to one flash.

Thread: OpenTx "feature"!
07/10/2019 16:12:01

I think you will find the channel value is that BEFORE any output limits are applied as well.

Even if you set the output limits to, say, -70% and +70%, the channel value still goes to -100% and +100% (and beyond).

Thread: A Terrifying story

Posted by Geoff Sleath on 01/10/2019 20:42:36:

The rule of thumb for maximum heart rate is 220 minus your age, so, in my case, 140. I have a fairly low pulse rate. When I was bored in meetings at work I'd check my pulse and it was always 52 - and that was in spite of (or perhaps because of) my 13 mile bike ride in from home. Even if I go flat out on the turbo now I can't get it over 150.

. . .

Geoff

I have to lie about my age in the gym, otherwise the machines keep saying "heart rate too high" and reducing the work level! I'm quite happy at a heart rate of 160-170, and my resting rate is below 60.

Thread: S8R problems...
27/09/2019 23:37:14

Please confirm that when you do the "self check", you get the blue LED flashing, then the servos do a "dance", then you move aileron, elevator and rudder controls to their limits, then power the Rx off.

Thread: V8R4-ii Rx not binding
20/09/2019 15:42:08

You are carrying out the correct procedure. Make sure you are using D8 mode on the Tx and not D16 mode with just 8 channels.

Thread: S6r Rx downloads
13/09/2019 22:45:55

Actually, it was a "hack" by me for erskyTx, and was added to openTx somewhat later!

FrSky did provide me with the updating protocol information so I could do it.

When trying to update devices from the PC, it is best if you power the device from a separate, switched supply. Get the updating software to the "Finding device" stage, then turn the power on to the device.

Thread: D8R-11 plus Receiver and EU LBT firmware
12/09/2019 09:29:46

Yes, someone else tested it on a D4R-II, I don't have any myself. I added the option of a SBUS output on channel 4 for the D4R-II.

Mike

For those wishing to use 'D' receivers, particularly with new "ACCESS" transmitters that don't support D8 mode, I've written new firmware for them that uses D16 mode. Details are here: **LINK**.

I test flew a D8R-II yesterday with this firmware and a Taranis plus. The Tx is still using "international" firmware (it is pre-2015). The 2 flights had no problems. This firmware actually supports both international and EU-LBT modes, and properly listens before transmitting telemetry data. You also have the option of using one of the servo outputs as a SBUS output.

Telemetry is still the hub protocol in to the Rx, although this is sent to the Tx in SPort data. I'm looking into being able to use the Tx and Rx signals, combined with a diode or transistor, to support SPort sensors.

Technically, D8 mode is no longer legal, for new equipment, in Europe, but is OK for equipment imported before 2015.

Thread: Cable tidy using sbus
29/08/2019 00:11:42

I have written a program that run on an Arduino Pro Mini, takes SBUS in and provides up to 16 servo pulse outputs, program and instructions here: **LINK**.

Take care if reducing the number of wires that the power and ground wires left are capable of carrying the current for all the servos/retracts in the wing.

If using two receivers, make sure only one one is configured to send telemetry. As an alternative to using links when binding, recent firmware on the X6R/X8R allows the channels and telemetry options to be configured from the Tx when binding.
