Should we put an end to requiring a traditional Tx for Multicopters?

Started by Edgar Scott. Last reply by Edgar Scott 1 hour ago. 19 Replies

Unless I'm mistaken I feel that diydrones would rather all flights use a Tx, but are we not very close to a point where we can to put an end of the Tx for drone multirotors as the primary flying…Continue

3.0.1
Have had brilliant results with this,
But !
Couple of days ago while testing pos hold my quad went off on its own, no response to controls, went up to 20 odd mts then wandered over to where my car was parked, then shut down (just missing my car)! Also just test hovering quad very twitchy, motors pulsing, like p settings way too high, but they not altered from before, any ideas ?

Failsafe & Turnigy 9X:  OK I'm a beginner, still Googling before my first flight. I thought the Turnigy 9x was popular/good/cheap/etc, but have found it does not provide any failsafe functions.

Here's my approach around this, rather than switching to FrySky.

I'm using the 900MHz telemetry system, & running Mission Planner on a small laptop. I read it has a further range than the 2.4GHz Turnigy. So I plan to monitor the battery voltage and whatever else I need, with the telemetry and hopefully do any needed 'recovery' actions.

A question: Does the Arduflyer 2.5 & the MP & the Turnigy 9x allow monitoring the signal strength of the 2.4GHz signal. I think the RSSI is the telemetry signal strength?

Any info appreciated

Just did CLI test on GPS and it seemed to report it was fine.

Did CLI test on compass and report said "Not Healthy".

I just noticed/confirmed, Mission Planner Flight Data page gives message, "No GPS". I had GPS when I first loaded firmware and flight data showed it locked on my house - 3 days ago...

Tx in mode 2.

No signal from Rx is recognized by the board unless I'm in ESC calibration.

I can calibrate ESCs, but can't arm the system afterwards. Also, I now don't get a GPS response.

Just swap over the cables from roll and yaw.

What mode is your Tx in?

Comment by Dan Skaggs on July 4, 2013 at 6:45pm
Mike, Tx is set to acro. Throttle bar was only moved in MP by throttle, but Rudder was moved by roll & roll was by rudder. That's why I initially thought receiver wires were wrong, but they checked out right (see Logan's comment below). Now I can't get board/ESCs to initialize.

Bo, good thought, but I read the same note about trimming throttle - tried it but no change.
Comment by Mike Boland on July 4, 2013 at 1:16pm

Have you got your Tx set to Heli by mistake, instead of Acro?

In your radio calibration window on mission planner, when you move throttle is only the throttle moving. This window with the moving bars should aid you in sorting out which channels are doing what.

When you move the rudder to the right is the rudder bar going to max?

Comment by bobarry on July 4, 2013 at 8:45am

I had problems arming, but it worked when selecting arm in the mission planner. Then I read that the throttle trim needed adjusting so that the down & to the right for four seconds really cuts the throttle to zero.

good luck.  bo
