Link to LiIon DIY battery with suppliers and method

PS every time I have tried to order these  batteries they have never turned up. The flying gods are looking after me again. Lol

  Hi Big T,

               I built my own 18650 3S and it was crap TBH....voltage sag even with a modest current draw.
  Besides I would need to install a 12 volt regulator on my VTX to use a 4S setup.  Can be done of course but the Z84 doesnt have a lot of room....as you know....lol.

Everything working really well ATM except nav launch. Was working well when on permanently, changed to a switch now not working at all. Reset to on all time, still not working. So.... going to reset to vanilla settings and try again. Also need to change vtx, current one is poo.

  Hi Big T,
                 Glad you finally have it working well m8...As I said, I had to revert to Autolaunch on the switch method to make it work reliably. Im using one of those huge TS832 vtxs with a Mic onboard. I like the channel changer and display....You can get them really cheap now because of their size. They are very robust and reliable though and 600mw.

Weird goings on with my Z84 yesterday. In a nutshell it flew great on days 1 and 2. Day 3 O My Gawd!! new Tx which obviously has different gimbals and switches so calibration is not the same, so I was expecting some issues but not as bad as experienced. Hand launch in manual resulted in near vertical climb and roll to the right. Servo autotrim could not handle the elevator but sorted the roll. Landed, disarmed to save settings, tried to launch in nav launch (on a switch) no go. Man launch to check trim still climbing so tried servo trim procedure again 3 times and finally got it level with trims centred. Half hour later flew it again and elevator out again. Repeat as above and got it level. Flew another pack to check horizon mode, alt hold and that was ok. Tried RTH LOS  and it buggered off and specked out into the distance! Luckily my pal had the gogs on and he talked me back into sight. The reverse of the correct procedure!   
Other issues are throttle not shutting off 100% of the time. Think I might start over and flash the FC again and set up the rx in iNav as a new model.

As an aside, even though the models where backed up in OpenTX and loaded onto the new tx, every one flown so far, except the Betaflight Racing quads, has been wildly out of trim.

It was a bit buttock clenching as the viz was pretty awful from the ground and these little wings get pretty small very quickly. As it was it was on the edge of video failure due to the low cloud and general humidity. My pal was observing on his fatsharks with a LaForge diversity that he was testing for the first time. He didnít realise that the patch antenna he was using was dodgy but the other Pagoda worked OK.  As an engineer a detest unreliability, especially something like RTH.

  Hi Big T,
               Have to say, after flying my Z84 for a while now, Im not surprised by this at all....Firstly, the Z84 is pretty sensitive to trim and it does not need much at all in the way of surface movements.
  Inside iNAV, (and my Taranis) I had to spend quite some time in the Receiver bar chart section making sure the throws and 1500 stick centres were spot on, with 1000 / 1500 / 2000 showing on all controls.

 After doing some meddling with linkages or throws or whatever, I always now make a point of getting the model straight into Horizon Mode after launch ASAP because I know the FC board trims are correct and unaffected by throws / trims / centres...Level is Level..lol.
 
 I could not get on with Servo Autotrim at all, and basically get the model at a safe height and then switch from Horizon into Manual and watch which way the plane deviates. Then, its land and adjust the quicklinks and try again until it's about right, very tedious indeed.

 Fact: You cannot use Autolaunch if your trims are not exactly centred...I think this also includes any Subtrim in your Taranis too as the FC is looking for 1500 centre and bugger all else. A strange way of going on, they might want to re-think this..?

  That's okay though, because I always set it up so that when it disengages Autolaunch, it goes straight into Horizon Mode, which is very handy, especially if you have to abandon Autolaunch by stick interruption.
  I only seem to use Manual these days during a hand launch or landing sometimes.

 Did you calibrate the sticks on your new Taranis..?....It seems there was nothing wrong with the old Taranis then..?

                                                                                               :vulture:

I did all the pre load stuff on the new tx, cal sticks etc. Only error I have is that the bootloader is not the same as the old tx. Not sure how that happened. My thought re trimming of old models is that the new Ď18 model tx has the new gimbals so algorithm is different.
There is a problem with the old tx, Richard thinks itís the voltage transformer and the old firmware of the module. No problem for me as the change over will only cost me about £50 net. Richard at T9 seems a really genuine chap. Nice in this day and age, reminds me of my Old Man.

How did you set the timer for launch mode up in the Taranis?

  Hi Big T,

                There is no timer to set in your Taranis...?

 You just need a spare channel to set up a switch so you can engage Launch Mode.

 Sequence:

1. Power your TX.

 2. Power the plane and wait for a Sat fix.

3. Engage Launch Mode.

4. Arm the Flight Controller.

5. Engage Horizon Mode (or a Mode of your choice)

6. Set the throttle to about 50%

7. Launch the model....(Don't touch the sticks or Autolaunch will disengage)

Sorry I didnít explain myself. I know how to do that. I thought you said in an earlier post that you had set a voice countdown to  report the condition. Must have been another contributor.

 Hi Big T,

               Oh, okay..I thought you knew how Autolaunch worked..:)

    Well, I think you may be referring to RSSI??? In the days before I had the luxury of an OSD with RSSI in the display, I used to have RSSI on a switch, and Amber calling out the DB signal strength every 5 seconds. I used to switch her on when I was out on the edge of my X8Rs range.
