Telemetry preflight check

[popokatepetl]

The idea is very simple. Connect discharged battery and radio tells you "You have connected discharged battery" and what's more important it automatically blocks the motor so you just can't start

This example is just a simple check of the main battery prior the flight but you can use Logical switches to check more telemetery values if you like.

Telemetry switch MX1
Rx voltage > 1.0V
Default value -100%
...to start the preflight check.
...it's important that the preflight check is done only once. It starts only once after radio receives the telemetry data which is the Rx voltage in this case. If you have some additional telemetry sensors which has a delay such as JLog, than I suggest using this telemetry value to be the start as MX1 for the Preflight check.

Sequencer Q1
0-10sec -125%
11-15sec +125%
16sec -125%
switch to start is the MX1
....this is the preflight check

Telemetry switch MX2
U battery > 49.0V
Start value -100%
Switch to enable this telemetry switch is Q1
...I'm using 12S LiPol which has to be at least 4,10V a cell as fully charged.

Sequencer Q2
0- 9999sec +125%
set cycling so it goes on and on
Switch to start the sequencer is MX2

Logical switch L1
Set condition when Q2 > 100%
Then use this L1 switch as the motor off switch in model menu.

And you can also set the L1 as voice command to tell you "You have connected discharged battery"

Similar to this so I thought I would put them together

I must have missed this thread. Mine adds the "motor off" feature.
...at least not exactly the same and it's little bit tuned.

Never hesitate to post anything always best to have too much than not enough and you never know when an improvement (as in this case) might come along.
