    I think this article may resolve my issue of the motors spinning-up at different times.

    Haven’t modified anything so all values are standard from firmware “triflight_0_5_ALPHA2_servo_release_RCE.hex”.

    Cheers

    The ESC’s, tail-tune and accelerometers were all calibrated just prior to the event.

    Made the first flight (video link):
    https://www.twitch.tv/videos/168415300

    However I did notice that the rear motor is delayed spinning up:
    https://www.twitch.tv/videos/168419201

    It’s like the rear motor comes on after the forward motors are already spun up. Which makes it feel as if its about to flip end over end. Not sure why this is happening but the tri did fly fine once i restarted a few times to ensure that the motors had spun up.

    Anyone know what could be causing this?

    Everything is programed and ready to go!

    Setting everything up for the test flight / tail-tune tomorrow morning. If all goes well, I should be able to make a video via the mobile display.

    Fingers crossed!

    David,

    We, received both the ESC and the motor today, swapping both out for the faulty ones. Motor test and spin direction performed perfectly.

    Soon we will program the Taranis and then match the Betaflight software to the channels / functions set.

    Cheers

    Found the problem…

    ESC was faulty.

    Unfortunately, the tail motor just smoke-checked itself. (it’s very hot to the touch) Closed out the video just before the motor died. Had I kept the video rolling 5 more seconds I’d of captured it.

    Please be aware that all motors are spinning at 10-15% of maximum just to verify operation and direction of rotation.

    Thanks BigRC,

    Will give different lens a look… However It does strike me as odd that this is possible with a cell phone camera but not for RC applications.

    As for the motors.

    Motor #3 (front left) wires swapped and works perfectly!

    Motor #1 (tail) reflowed all connections and replaces control wires (white / black 20 gage) but yet the motor still pulses rather than spins. It’s possible I guess that one of the power wires from the board to the esc could have a break mid line but that is extremely rare. I’ll give the esc an alcohol cleaning while rubbing it with a cosmetic brush. This should remove any solder-balls (if any as I did look before) while drying quickly, without leaving a residue.

    Was Finally able to get the Betaflight working after downloading “ImpulseRC_Driver_Fixer.exe” from: http://www.dronetrest.com/t/fix-any-stm32-dfu-drivers-issues-when-flashing-betaflight-cleanflight-firmware/3603

    With this I was able to access the flight configuration and verify that the tri-copters receiver is paired with its RC transmitter correctly. During further examination, Motor #1 (tail) is pulsing, which makes me think that there’s a cold solder joint somewhere or a damaged ESC. Motor #2 (right front) works great! Motor #3 (front left) is spinning the wrong way and needs a few wires swapped.

    I’ve yet setup flight controls and special switches and as such not tested the tail servo. Will have a go at this once the motors are all spinning the right way and not pulsing.

    Note: If all goes well the parts for the battery adapter will come in tomorrow so i can finally charge of the FPV goggles battery.

    Odds are the STM32 virtual com port driver is causing issues and I dont see why.

    Tried reinstalling all drivers but yet same issue… Can load firmware but not load into Betaflight’s configuration for the F3FC flight controller.

    Example:
    -Insert the USB cable to the F3FC board (boot button held) and the “STM32 Bootloader” shows in the device manager. Lights are shown on F3FC board and PC recognizes the new device.
    -Load-in and install the firmware to the F3FC from Betaflight(v3.2.1) “triflight_0.7_Beta2_RCEXPLORERF3.hex” after which the Bootloader kicks off and becomes the “STM32 Virtual Com Port”.
    -Past this point Betaflight will not allow me to connect to the virtual device and says “Failed to open serial port”

    Attempts to reinstall en.stsw-stm32102.zip / CP210x_Windows_Drivers.zip and use Zadig have no effect.

    Anyone know whats going on here?

    Progress
    1) Frsky Taranis Transmitter and Frsky XM+ receiver both updated with the latest firmware. (EU)
    2) Frsky XM+ Receiver board bound to Taranis Transmitter. (Fail safe too)
    3) All batteries charged except the battery for FPV goggles. Awaiting parts to build 5.5mm Adapter to xt60. Using xt60 (female) and 5.5mm barrel (male). Sucks that this isn’t available online nor with the charger.
    4) Video camera and vtx installed and verified working via external monitor. However the video looks as if it’s shot from a fisheye lense. Either this needs corrected or replaced. May opt to replace as the camera doesn’t fit the camera mount properly. Unfortunately finding a board based camera remains an issue.

    Note: Rigging up the cabling for the video and vtx has been by far the biggest headache of the build. None of the connectors are standardized and often one or more connectors needs to be rewired or replaced outright.

    Major issue (Need Help)
    -Connecting to the tricopter via Betaflight is a constant issue. Zadig loaded and still after the F3FC firmware update, I’m unable to load into the configuration screen. Be aware that I was able to get it to work once on my wife’s laptop. However recently even this is failing to connect. Not sure what i can do as this issue persists on both my PC and now my wife’s Laptop.

    Current build…

    Just under 600 grams with props and battery.

    Woot!

    Got in via a combination of my wife’s old laptop & Betaflight!!!

    So far I’ve tried Cleanflight and Betaflight without luck.

    I’m thinking this is a comms / driver issue of some form. Even attempted doing a safeboot with driver signature enforcement disabled without any noticeable change.

    Will try the sequence via my wife’s laptop but I’m not overly optimistic as it too is a Windows machine.
