    No drones or trees were harmed during the making of this movie.

    Here's some race practice for an upcoming MultiGP race:

    Apparently 35 degree tilt on my mobius isn't cutting it anymore...

    Hi Guys, Just built QAV-R, with LUX FC,2206-11 2350Kv motors, FVT Little Bee 20A PRO ESCs, running 4s 1550mAh 75c battery

    Can anyone give me some PIDs for CLeanflight to get started with please

    The defaults on the latest version of cleanflight should work for you and get you started. Be sure to use the Luxfloat PID controller.

    Also check out Furadi's PID tuning video on YouTube. He explains things well.

    Here is a little crash compilation I made as a last salute to the QAV-R before I kiss the frame goodbye.

    I'm finally getting around to building this QAV-R that I bought a year ago. And that means designing some more parts for the 3D printer. Here's one that I just finished up. It's a protective cover for the RGB LED distribution board:

    Now I'm working on some LED holders for the arms that will protect the LED AND, if you use a translucent/clear filament, make the light easier to see by scattering it.

    Building a*QAV 250r and QAV x can I just download Inav firmware to Flight controlled and not have to have a GPS antenna and say aDJI nav trying to understand this new to fpv never built drones or flown and building two right now one for me and one for son. Please explain as for my 250r for my son I just ordered a DJI Nav from getfpv so he could have the return home feature which will add weight that I would like to get rid of. If I understand this correctly I would just purchase say a KISS flight controller and download the Inav firmware which is free and I could eliminate the GPS antenna and return the DJI nav system to getfpv? and I could do the same for the QAVX that I am building which is too small to add a gps Flight controller this way the QAVx would have a return to home feature as well with no added weight? or am I way off here someone please help me understand. Thanks very nice QAV by the way


    I have also been looking for some help with these QAV builds and have posted below what I could use help with on some FPV forums with no luck so if someone could assist I would surely be grateful!

    New to this sport, never flown or built before, I am sparing no expense in building two drones so I want to get this right. I am currently ordering parts to build my son a QAV 250r and I ordered a QAV x for myself. Below is what I have ordered for parts and I need some help with eCalc configurations to give me some specs on what I am building. I am looking for optimal prop size and pitch with the motor and size I chose along with optimal ESC to handle the motors on a 4s 95c 1300MAH Luminier battery.
    OEM Lumenier QAV X and QAV 250r will have PRO Tmotor F40 2600KV motors, Kiss 30 AMP ESC, 4s 1300 MAH 95c Batteries, 5045/3 Props. I seeking to get out of the 250r to 80-90 MPH and my QAV X to 95-100 MPH if not faster with decent fly time!
    My eCalc configurator shows that I am not even close to desired MPH and fly time for both QAV X and QAV 250r and shows my ESCís, (KISS 30 AMP) are too small and I, need a bigger AMP ESCís, it also shows my Pitch is way off and shows low MPH for both QAVís. (I could be entering the wrong information based on lack of experience which is why I need your help)
    Can someone configure both QAVís for me and let me know the following
    a) What optimal ESC and Prop size/Pitch would be for both build configurations and what prop would you suggest?
    b) What Max Speed will be for both QAVís QAV 250r for my son and QAV X for myself?
    c)What is the fly time for each?
    d) What is your experienced opinion about the Motors ESC, Battery and Prop selection I choose for each the QAV 250r and the QAV X builds. Is there a more efficient, more powerful lighter better combination you would have gone with to make each QAV sick performing drones? if so what would you have chosen? Please email me product info and why you would have gone that route so I can research and change products before I build.
    e) What is it you would do to maximize each QAV with the Motor, ESC, Battery and Prop to get the most out of each QAV.
    You can email me at or text me at 989-359-1026 I will be building these QAVís this week and parts are arriving daily so time is off the essence and I need an experienced FPV Drone builder to help. Best regards,

    Good old QAV-R!

    Recently I have changed the complete setup of my QAV-R. This is now definitely the smoothest Quad, I‘ve ever flown!
    Watch the first eight seconds and make your decision: Smooth or not?
