    Product Description

    The Mini Tricopter, a different mini multirotor that packs a punch.

    The Mini Tricopter was designed to utilise parts from the Tricopter V3. It uses the same Naze and PDBservo, tilt mechanism, motor mounts, front spacer and arms (cut to half length). Which means that you can convert your regular size tricopter to a Mini Tricopter simply by cutting the arms (or getting new pre-cut ones) and screwing on the Mini Tricopter add-on frame. (Warning: cutting carbon fiber is dangerous and may harm your health. Use proper protection if you try it.) Also, don’t forget to downsize the electronics accordingly.

    Mini Tricopter Camera Tilt
    The frame has a built in adjustable mount for a board-camera with up to a 40x40mm footprint. The angle can be adjusted continuously between 0 and 40° so that you can start out easy and as you progress in your flying, you can add more and more angle to the camera. The camera is well protected by the frame itself as well as the fact that it is held in place by rubber bands, which protects the camera even more during a crash.

    The Mini Tricopter also easily carries a GoPro camera with protective housing. The camera is easily mounted on the top of the frame. A GoPro4 session or Mobius/Runcam can be mounted inside of the frame on the Mobius Shelf. This plate can be mounted in two positions to allow for different configurations and camera angles. The supplied silicone camera wedge can be used to fine tune the angle of the camera.

    Flying the Mini Tricopter can be best described as driving an overpowered rear-drive car. It’s not the fastest around the track, but you’ll have the biggest grin on your face when the race is over. The recommended electronics package makes this little beast go almost 160km/h (100mph). The thin arms and smallish body makes it pretty aerodynamically slippery. It requires very little power to cruise at high speeds and it absolutely loves long low-passes with big wide turns. Flips, loops and rolls are quick and crisp thanks to the center of gravity and center of mass being very close to each other.

    Transporting the Mini Tricopter is really easy as the arms can be folded back, just like on the larger tricopter. Folded up it’s only 10cm wide and 30cm long (35cm with 6 inch props sticking out straight back) and 8cm tall. The folding design also makes the Mini Tricopter crash resistant, as the arms may fold back, absorbing energy. The tough “cage” protects the electronics and battery on the inside.

    The recommended battery size for the Mini Tricopter is a 4S 1800mAh with a C rating of 35 and upwards. Be sure to check the size of the battery as only batteries up to 110x35x35mm will fit inside of the “cage”. Larger batteries can be fitted on top or below but you’d lose the protection. I also highly recommend using the tricopter frame with integrated NAZE32 and the PowerDistribution frame with BEC as otherwise it will get really cramped inside of the “cage”.

    When using the Power distribution frame with BEC, it is not  recommended to power an OSD, High power LED’s or similar from the BEC at the same time as the servo. It can lead to the chip overheating.

    Tricopters have received very little love in the development of modern flight controller code. With the Mini Tricopter this became very obvious as the yaw performance in the original Cleanflight code was lacking. I tried my best tuning the PID’s but I couldn’t get it to a level of performance I was satisfied with. This is when the community really stepped up to the challenge. The user Lauka, on the forums, wrote a special Tricopter version of the Cleanflight code called “Triflight”, which with it’s many alterations, already has improved performance greatly. The yaw is still not quite perfect but we will continually try to improve upon the code and PID settings. You can join us in this quest for perfection simply by posting your findings in this thread. Together we can bring back the tricopter with it’s phenomenal flight characteristics from the brink of extinction.

    To make setup as smooth as possible all PID’s, filters, TPA, tail TPA and such are already tuned for the recommended electronics package. Just click the “Preconfigured Cleanflight Setup” tab above and follow the instructions.

    Pinout for the ESC’s and servo is (Looking at the tricopter from above with the tail pointing towards you):
    Motor pin 5 is left ESC
    Motor pin 4 is right ESC
    Motor pin 3 is back ESC
    Motor Pin 1 is servo

    Preconfigured Cleanflight Setup

    Update 2/1-2016: New version of Triflight 0.4 final released. Link down below updated.

    Warning! This setup is intended to be used with the recommended electronics for the tricopter. Especially important is using SimonK/BLHeli flashed ESC’s and a digital servo capable of 250Hz update rate (Such as the BMS-210MH) Using an analog servo with this setup file will result in a burnt servo!

    Download and install the USB to UART driver
    Download and install the Google Chrome
    Install the CleanFlight App from the Chrome app store and launch it

    The tricopter will fly better with the propellers mounted the following (Copter seen from above): left – CCW, right – CW, tail – CCW. This will help in coordinated turns. It’s not a big deal if front motors are swapped, with left rotating CW and right CCW. It will only mean that you will be fighting it a bit more with stick inputs in the turns. However the CCW rotation of the tail motor is absolutely critical for proper triflight behavior. It will not fly well with the CW tail motor.

    Pre-installation: Check your configurator version and if it is lower than 0.66, update it. Be aware, that triflight requires BLHeli 14.0 or higher or one of the latest versions of SimonK firmware on your ESCs to work in Oneshot125 mode. If you skip this step the copter might power up accidentally and cause serious harm. It will also not be able to fly as it won’t recognise the oneshot125 signal.

    Installation: Download the triflight_NAZE.hex file. Flash it to your Naze32 compatible board with the cleanflight-configurator as usual, but make sure to tick “full chip erase”.

    Configuration: Setup your receiver (midpoints around 1500, min as close to 1000 from above as possible, max as close to 2000 from below as possible, also make sure to setup the deadband and yaw_deadband, as well as the board orientation (for integrated tricopter frame set pitch adjustment to 180), failsafe and any other features you would like to use. Next setup any mode switches you might want to use and I recommend setting the arm function to a switch. Calibrate the accelerometer on the flat surface (Mini Tricopter will need to have the cage sticking out over the table to be flat). Don’t forget to calibrate your ESCs also.

    The tricopter requires some configuration related to the tail servo. The most important is servo midpoint and endpoint adjustments. All the algorithms added for more stable and precise yaw control rely on the correct servo configuration, so follow the steps below with the most accuracy possible. It is highly recommended to use the Tail setup tool, which is included in the newer kits.

    Make sure your tricopter is level on the roll axis. If you have calibrated your accelerometer on the level surface already, make sure it shows zero roll.
    You will need to connect the battery or some other source of flight power to your tricopter to continue, so make sure the propellers are off.

    We will be using trial and error approach to the servo configuration. We’ll need to find the mid, min and max values that will give us the desired middle, leftmost and rightmost positions of the servo respectively. Triflight assumes that at the mid position the servo is pointing the motor shaft straight up. It also assumes that at the min and max throw is equals to 40° in each direction.

    Go to the servo tab of the configurator and enable “live mode”. Servo 5 is the tail servo for the tricopter. Mount the servo setup tool with the pointy ends up touching the tilt top piece slanted edges. Change the MID value until the top piece has perfect contact with both surfaces of the setup tool. You now have a perfect 0° angle for the mid point. Next flip the tool over. Move the yaw stick on your transmitter and adjust the corresponding value (either min or max) until the tilt is laying flat against the setup tool. Increasing the Min value will yield less throw to that side, lowering the Max value will reduce the throw. Repeat for the other direction. If you can’t achieve the tilt to touch the other side of the tool you’ve changed the wrong value. Start again but adjust the other value (Min instead of Max or vice versa). After you’ve done with this, double check both directions and the center. If they are all good. Click the save button at the bottom to store the values permanently.

    You can do the setup using a protractor, but it’s less accurate and difficult to do. You’re looking for the values for 50 (min), 90 (mid) and 130 (max) degrees from the horizon.

    PID values are already adjusted in the file (no more need to paste any dump files) for the stock mini, but feel free to tune to your liking. It is not recommending to paste full CLI setups from any other firmware at this point.

    You’re almost done! Go to the Modes tab and setup a switch to activate the “Tail tune”. Hit save after you’re done. Mount the propellers and go outside. We’re now going to do an inflight calibration of the thrust factor value. Put the copter into a hover.
    Switch to TAILTUNE mode. You will hear a beeping battern from buzzer as a confirmation.
    Keep the copter in hover. The tuning process is only active when you don’t touch the pitch & roll & yaw sticks. You can of course use the sticks to keep the copter in place, the tuning process will continue when you release the sticks. FW will do beeps during the tuning (1 beep = decrease the ratio, 2 beeps = increase). Once tuning is done, you will hear same beeping pattern as when you first activated the tail tune mode, it will repeat every 2 seconds. Disable the tail tune mode again, land and disarm. To save the new settings either using stick command (left stick bottom left AND right stick bottom right on mode 2 radios).

    You’re done! Enjoy your first flight.

    If you’re using some other servo or powering your servo with something other than 5V, you might need to adjust the tri_tail_servo_speed CLI variable to match the speed of your servo. It is the angular speed of the servo in degrees per second under load. Default value is 300 and it’s close enough for the BlueBird BMS-210DMH servo, powered with 5 volts.

      This little aircraft is a rocket on rails! In my fleet of six Tri-Copters this one is now my favorite. I’m running a slightly different setup with ESCs and motors(Cobra 2208/2000kv and RotorGeeks RG20 BLHeli ESCs). I didn’t change any settings on the preconfigured Cleanflight Setup and it flew first maiden just great. David,you did a great job on this one.

      Just got mine in the air yesterday. You couldn’t ask for an easier build. The integrated PDB and Naze32 make this a joy to construct. The tail is a work of art. Easy to put together and solid. No slop whatsoever. The video is nice, but I am a little confused why the mobius plate points so far down. I would have expected it to point up.

      Awesome little fun machine. I had some trouble with the tricopter.hex and my pwm receiver but now it flying great and stable from the beginning. Great product. Very well done David!

      Thumbs up.

      I’ve been flying this now for a few days, and really love how it handles. The build was very easy. I had never used a Naze32 board before, but with the video instructions, I was able to get it set up with no problem. The Preconfigured Cleanflight setup along with Triflight made it fly very well immediately with very little fiddling. Acro mode took some tuning for me, I found it WAY too responsive initially. If it is your first time flying one of these, I would highly recommend turning your ROLL rate and PITCH rate down to about 0.20 before trying Acro and moving back up from there. This thing is stable enough that I’m planning to move to this frame for my travel video platform. The integrated PDB and NAZE32 board make it really compact and clean. I also have the tricopter v3 and love it, but if I could only have one, I think I would choose the Mini

      What a joy this was for a first timer into multirotors – the store, delivery (Australia), the various build guides and forum support all painless. Extremely well engineered and manufactured (Naze and PDB options added). A rewarding build (not just unboxing an RTF). Great to fly. The folding design and size make this so easy to pack and take anywhere. A very happy customer. Thank you David.

      This is without a doubt the best tricopter kit out there at this moment in time, nothing comes close. Paired with the MiniTricopter Electronics kit it is a breeze to assemble and get up in the air, the combination of the hardware, software and community is what makes this an incredible piece of kit. Stable from first flight with no changes to PID settings, for a beginner you could not ask for more. This is my third and only successful attempt at building a tricopter kit and getting it into the air.

      Take the plunge you wont regret it, a worthy investment in my view.

      Good evening
      I have now ordered a Tricopter.
      My question is there is a built Naze rev6 or rev5
      because I would like to take S.BUS.
      in rev 6 I have no inverter using at rev 5 already.
      Thanks for the answer.

      • :

        Rev 5 so you need an inverter or modify your receiver
