Just started with the videos so intending to cover some of the basics to start with then I'll focus more on the programming examples. I have a day job...
so the videos are just a quick knock-up. I try and just do the complete video in the one take so I dont have to spend time editing it later... So not overly pro but good enough to get the message across.Hardest bit is trying to get my camera to capture the LCD screen correctly... Usually end up with some weird colours or moire patterns depending on what screens are being shown.
With regards to the Fast Start feature it doesn't impact the overall boot time that much but what it does do is it allows you to control the model right after the Tx is powered on. So screen will be blank (or show the Core logo) at this stage however you can control the servos while the Tx is still booting and loading the OS.
*Note that the trims are disabled until the Tx has fully booted.

Watch your receivers, they will go green in about 4-5 seconds and you can move the servos and such. I'm not sure but if your tubine is on a switch you may be able to start it as well, or you may need to have it in the correct trim prior to shutting down and then you can throttle up and down to start it while the screen is booting up.

The transmitters come with Samsung INR18650-35E cells. If you look at the data sheet for these batteries Samsiung specify an absolute minimum discharge voltage of 2.65v per cell (ie 5.3v per 2S battery).
You dont really want to discharge the cells down that far every time you use the Tx as that just stresses the cells more so you want to leave some safety margin here.
I would use 3v per cell as a safer low voltage critical discharge point ie. Never go beyond this point.
From memory I think the fixed battery indicators turn orange around 7v or so (3.5v per cell) so I would use this as a minor warning to be aware that the batteries will require charging soon. This provides you with ample capacity headroom and time before the batteries become dead flat.
Ideally, for maximum cell life you don't want the batteries to become too discharged and you also don't want them to be charged to 100% either as the cells don't really like being at 100% for long periods of time as this can impact their overall capacity.

Yeah, I had set up 2 of the 26D on my Rebel Max and didn't turn it on for a while, went to the field and had to bind both of them again. A little concerning but then they range tested fine. I am going to maiden it tomorrow if the weather is good and was just wondering.

Hello All, the new 14 CH RX looks great for small/medium size models where you do not wish to run an additional power distribution box. Considering the unit only has one power input, what are peoples thoughts on the best/alternate types of set-ups to run two independent power supplies, etc? BRG, Frank

If you want multiple receivers and power input then just run a Pioneer. This is for smaller models that don't need that. It would have been perfect for my Harlock Viper a 45N turbine jet with nose steering, gear, brakes et all but no need for a serious power distribution system.

That's the obvious solution, however I'm really chasing a set up for those really small models where every gram counts and the emphasis is on having power supply redundancy and low complexity/weight/cost, less points of failure - so a power distribution system is the least preferred alternative

I should have a couple of these receivers very soon, they are on their way.
I always like to have two power inputs to any receiver, so I will use the 20 amp plug AND connect another input to the final servo socket.
For many years, on smaller receivers, Weatronic and JR, I have connected one power input to the first servo socket and the second to the final servo socket. I am told this actually increases, doubles, the power capability of the receiver power bus, Kirchoffs law. Of course , after this experience it may well be possible to couple one power input to servo plug 1 and the other to servo plug 14 on the 14 ch receiver. Readouts from my Weatronics Gizmo shows typical amperage of 3.5 on my AW Hawks which have multiple high power servos.
Whether you use this method or a Pioneer voltage regulation is still needed so a sensor switch is the solution.
As usual I will test it and see !

You might want to double check with Richard in regards to that configuration as the 14ch Rx has an electronic 'fail safe' style soft switch built-in.
By connecting power to a servo socket you will be feeding power back to the output of the electronic switch which may cause problems...?

Hello David/CostasV, thanks for your responses. David, I look forward to your test results. I guess another alternative could be to connect two separate batteries/switches/regs in parallel (y-lead) to the single power port.

I will check with Richard, I am not aware of the soft switch process.
There is some discussion of this issue on the forum but my German is insufficient to translate !
Pioneer, expander, and now a 14 ch receiver, we really are spoilt for choice !

There is a small blue pushbutton on the Rx.
Press for 2 or 3 secs then press agin to switch on etc... (same power on/off sequence as their other gear).
It also features a socket for a remote switch (eg their mag switch) if you want or need to remotely mount a power switch.
