CAD files can be found here:

This is my latest 15 inch ultra-long range setup with 50 minutes flight time:

  • Propellers: 15x5.5" Tarot with custom hub
  • Motors: T-Motor MN3110 470 kV
  • Frame: 240g custom carbon structure
  • Lipo: 2x 4S 4000 mAh SLS 20C (parallel)
  • Camera: Micro Runcam micro sparrow
  • Firmware: INAV
  • FC: Holybro Kakute F7
  • ESC: Tekko32 F3
  • GPS BN-180
  • Compass: QMC5883L
  • Receiver: FRSky R9 slim+
    Hovering flight time is 50 minutes at 8.5 Amps and 40% throttle. Current goes up to 12 A when flying 50-60 km/h

Flight characteristics are really good when tuned properly (you'll nee a HUGE D-term). INAV 2.4.0 PID settings:

set mc_p_pitch = 85
set mc_i_pitch = 60
set mc_d_pitch = 150
set mc_p_roll = 85
set mc_i_roll = 60
set mc_d_roll = 150
set mc_p_yaw = 200
set mc_i_yaw = 70
set mc_p_level = 40
set mc_i_level = 10
set max_angle_inclination_rll = 500
set max_angle_inclination_pit = 500
set dterm_lpf_hz = 30
set use_dterm_fir_filter = OFF
set yaw_lpf_hz = 50
set dterm_setpoint_weight = 0.600
set dterm_notch_hz = 108
set dterm_notch_cutoff = 72
set rate_accel_limit_roll_pitch = 2400
set rate_accel_limit_yaw = 360
set heading_hold_rate_limit = 30
set d_boost_factor = 1.500
set d_boost_gyro_delta_lpf_hz = 40
set antigravity_gain = 2.000
set antigravity_accelerator = 5.000
set tpa_rate = 20
set rc_expo = 77
set roll_rate = 27
set pitch_rate = 27

Nice build! I'm working on a 15-inch prop drone of my own right now. Did you ever migrate from 2.6 to 6.1 by chance? And if you did were your posted PID settings still a good start for you? Thanks!

Amazing! Would love to see a video of it in action. If you're not willing to share the drawing for the custom frame, is there an alternative frame that you can reccomend? :)

Shrediquette   Apr 17, 2020 

I updated the description with the link to the CAD files.

Dev   Apr 21, 2020 

Cool! Thanks :+)

Oh wow! Didn't expect to see you here, your blog was a huge inspiration to me back when I first got into the hobby - your Bolt hexacopter was what really made me want to try designing my own frames :) Great to see you're still coming up with awesome projects, this looks fantastic!

Shrediquette   Apr 17, 2020 

Funny, thanks :) Yes I am not that active anymore - I just have produced too many daughters that take all my time.... X-)

huge kudos for using my favorite cam ever! Micro sparrow 2 is dabomb

Very nice build. But for some more serious long range flights, which your rig is certainly capable of, I reccomend mounting your RX & TX RC antennas vertically. Horizontal antenna config gives a very incosistent signal and failsafes not far out.

Shrediquette   Apr 11, 2020 

Hi, the antennas will be almost vertical in forward flight. And they'll be 90 degrees to another. I think this is a good compromise.

fmcprogrmr   Apr 11, 2020 

Yes but you can't/shouldn't take a break from forward flight to enjoy the view or check something out. You don't have to worry about any of those things with a vertical setup. I flew with the same antenna setup and R9 for awhile and it was sketchy as hell signal consistency wise until I switched to a vertical setup. Love your build!

Omg i love the name!! its so new!! was it inspired from something? just kidding hahaha...lookssss sleek dude!! the smooth body and tube arms look so smooth!!

Shrediquette   Apr 11, 2020 

Well, yes... There is a famous beer brand with a similar name - I confess... :)

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
