    Kit has arrived! 😀 Transfer of components from EZbi #2 has commenced!

    RCE build begins!

    Cheers!

    And now there is a build video! 😀

    Just waiting for my kit to arrive…. 😀

    It’s a mount that is 45 degrees to the main spar. I tried to make it simple so that it would be easy to swap it in and out without major changes to any wiring/gear. So a 14×14 tube with ID of 10×10, with a 10x14x70 solid beam intersecting. In theory, you could zip tie the Impossible tilt to it as well as the stock RCE tilt. I’ll post up the .stl as well as the OpenSCAD file used to create it to my Thingiverse feed later today.

    Cheers!

    Testing Oblique Active Tilting on the EZBicopter with a 3D printed mod. Initial test flights allowed me to fly with default PIDs where I had to cut PIDs in half before. It’s a simple slip on mod. I do believe that a tail of some sort will be required to help stabilize the pitch axis. Currently, all the mass is at the centerline of the EZbi and it is very susceptible to swiging like a ball on a string.

    in reply to: I ripped the buzzer ground pad off my F3FC board :( #58905

    The Ground pad is the switched pad for the buzzer, not the 5V pad. So using any other ground pad will result in a constant beep. Depending on how far back it pulled off, you may be able to clean the trace off and solder to it… Not sure how feasible this is on the F3FC. Will look at some pictures to see if there is somewhere plausible to pick it up other than the pad….

    Cheers!

    EDIT: The Buzzer- pad connects through the board to a FET on the top side. It makes it’s way through just next to the PWM 3 pad. The Buzzer/beeper pad is switched with a FET because of the load it can potentially draw. Hooking to the LED pad may work, but is not necessarily a good idea. I would HIGHLY recommend soldering to the FET. You can see it in this edited store photo

    I have EZbi #2 pictured above all wired up, configured with @jilein’s latest F3FClite branch, tested the mix, and ready to maiden. Just need to get rid of all this rain. Looks like Sunday at the earliest…

    Pretty much configured the same as EZbi #1, but with more stock RCExplorer parts. 😀
    Baby PDB @6V for servos
    F3FC Racing FC
    Current/voltage monitoring configured
    RCE Tilts
    PWM1 Right motor
    PWM2 Left Motor
    PWM3 Right Servo
    PWM4 Left servo
    UART1 RX -> R-XSR SBUS
    UART3 TX -> R-XSR S.Port telemetry

    Left UART2 open in case we use it for feedback at a later date.

    Will move all the electronics over when my RCE BiCopter kit gets here.

    Cheers!

    EDIT: So the sun popped out while I was grillin’ up dinner which made me a bit antsy to give it a maiden. Threw caution to the wind and put it immediately in the dirt. Forgot to adjust the board orientation in the config for 90 degree rotation in anticipation of the RCE frame. Stick mix was right, Gyro mix was off 90 degrees, Which means I have some cleaning to do before the next dry spell. LOL

    @david,
    Yeah, @jihlein was thinking the F3FC Racing was like the integrated PDB/FC of the mini tri and V4. Once he realized/remembered that the BabyPDB and F3FC Racing were separate boards and the ADCs for Power/Voltage are exposed pins, that made a world of difference. 😀

    Cheers!

    Been working on a second EZbi with my spare RCExplorer tilts, Baby PDB, and F3FC Racing. Trying to get it in the air without chopping any wires so I don’t have to extend anything once the RCE kit gets here. I’ll test dRonin with the F3FC on this build until the Kits arrive. :-D… Working with @jihlein to figure out the best PWM mapping that also allows for dual servo feedback.

    @Kevin_Eric,
    I can take an educated guess at a two.

    1) You can add FPV to just about anything with a little work.
    2) Can’t speak to this, I’ll let @david answer this one.
    3) @jihlein and I are already working on dRonin support and testing. He’s getting OpenAeroVTOL merged in along with his TriFlight branch. This might provide some real benefits. He is also working on adding support for a second feedback pin, so the feedback signal from both servos could be used.
    4) This is Another question for @david to answer.

    Cheers!

    The yaw on a quad tracks much closer to anticipated than the slow servo on a tri. If you compare my BT1yaw vs BT2Yaw, you might be able to tell which one has the faster servo.

    Graphs from my Mini Tris.
    MT1 = DTFc FC icm-20608
    MT2 = Seppuku FC Bosch BMI160

    The F3FC builds with the MPU6000 are MUCH cleaner. All four of the FCs are soft mounted.

    Cheers!

    My baby tri graphs are unbelievably smooth with the F3FC. These are the graphs I got from my mass tune back in July. FWIW, your graphs though noisier than mine, do not look that bad.

    @jgalbraith,
    A little more information would be helpful. What firmware are you running, what ports do you have the motors and servo connected to, are you using all RCExplorer parts, or have you mixed in some of your own parts? Maybe a few pictures of your build too.

    Cheers!

    I’ve made a bit of progress today, still not dialed in but got rid of the uncontrolled oscillations. Cut default PIDs in half and got rid of leveling on pitch axis. Using Rate(acro) on pitch it will eventually get into a pitch oscillation. Lowering the battery, or adding some horizontal stabilizers might fix that, but I’m going to lower the pitch mix and try to get it to work with manual pitch mode. Currently with pitch in manual mode, it tries to flip over forward or backwards and roll across the ground. Really need to get some video so you can see all the fun I’m having. Haven’t killed or hurt a prop yet even with plenty of grounding the props.

    Cheers!
