Tri-Ronin(™) & Matek F405-CTR target testing

[Kevin_Erik]

Battery test went well… No magic smoke, motors spin up in the right direction too. Only thing is that the Servo isn’t responding nor does it self center when the copter is first powered up.

[Kevin_Erik]

Ok got it working!
Did a quick bench tail calibration using 4S and 6v BEC (3A).

tri_tail_servo_speed = 282

[Kevin_Erik]

Finished assembling the Tricopter-Baby with full FPV gear!
Flight Ready Weight 482.6 Grams using 1300mAh 4S lipo.
Redid the Tail Bench calibration using only battery power:
tri_tail_servo_speed = 321
tri_tail_motor_thrustfactor = 56

Currently have one of David’s BMS210D Servos connected to a Turnigy 5 V/6 V/5 A SBEC. (60mm x 25mm x 11mm @ 20 Grams) Plan on replacing it with Henge 4A UBEC 5V / 6V (35mm x 20mm x 5.8mm @ 16 grams) Hoping to drop another 5-10 grams as well as make the placement significantly easier. The Turnigy could only fit under the main frame and only then it barely fit.

Note: Currently using LS2207-2550kv motors instead of the 1900kv motors. Should be easier to tune and fly at least until i am certain of how it will behave.

Did tail tune, np worked great…

Did a short flight afterwards, then saw the tail motor surge causing the copter to nose over into the ground. (from 2 meters up) Other than my camera mount needing reattachment the copter looks fine.

At this point, it could be one of the following.
-Bad ESC or ESC setting.
-Faulting wiring to from ESC.

Note: Motors felt really warm considering that I didn’t throttle hard.

[Kevin_Erik]

Rewired all of my motors to discover that the ESC for motor #1 is bad. Motor ohm’d out at 0.7-0.8 ohms per loop and the ESC has voltage across it’s inputs. Notice in the the attached image the ESC #1 isn’t showing up.

Note; I think these esc’s were the ones i used with the F80’s motors that desynced.

Replaced the ESC with one from the Tri-Mini that was awaiting to be rebuilt.
All’s good again!

Ordered two new ones so i have a spare for next time.

[Kevin_Erik]

Was able to complete two full flights with the Tri-Baby.
Will post the Plasma Tree soon.

*** Updates ***

I rolled in some updates to the myDronin branch that everything is currently built from.

1)Merged to the latest dRonin Next branch, pulling in the latest changes.
2)Modified the F3Fc target to match the default F3Fc Racing gyro/accel orientation.
3)Changed F3Fc Firmware tab picture from F3Fc Copter board to F3Fc Racing board.
4)I don’t know why I didn’t think of this earlier, but figured out how to add the Triflight parameters
to the TXPID module, so they can be varied in flight. And it worked the first attempt.

It is not necessary to update, only if you want the bleeding edge!

Have fun, proceed with care…..

Thanks mate, have a good weekend!

[Kevin_Erik]

Under the UAVO Data objects, there is a TriflightStatus object, you can see the servo data change as the Servo is being moved. (Feedback, angle, correction) Nice way to see that everything is installed correctly.

@jihlein

Ok Tri-Ronin(™) is installed and the motors spinning in the right directions. (Vehicle Wizard is of not help here BTW) Quick question about the attached image…

The rate settings shown for channel 1 are obviously intended for the Servo.
Figuring that the Servo needs PWM and can handle an update of 250hz, the best choice for this would be “165” or “270” ?

Side Question: you had mentioned earlier that for the Telemetry to be read by the Taranis that it needed a compatible Lua script. Does this already exist is some form?

Here are a few screenshots of the current Tri-Ronin(™) / Matek setup.

@jihlein
Autotune and Tail tune… Which needs to be done first? I’ve noticed that they both use the Flight-Mode switch so I’m thinking it may not be possible or wise to do both within the same flight.
