3d printed PLA Whirlygig tricopter by 1Smug_Bastard. Been wanting something toothpick-esque in a tricopter and here it is.
Strictly LOS. I stink at FPV.
Inverted FC. Soldered servo to resource mapped led_strip tabs.
Fun build. Not a rocket. Not a slug. Just a nice flying experience.

In the middle of printing this and sourcing parts together. I had to order that servo from the UK lol
WHOAAA dudee how did you use the led pad as the servo signal? Also i hope you can show a bit of the flights (maybe a 3rd person cam?). Seems like a great quad!!
Quick question, how did you get your motors into the pico connectors? Did they come preinstalled like that? Dont recall my DYS motors having any.
Great build! How does it fly for you?
Side note: There is an update to the frame that should be stiffer and easier to print.
it flies great. thoroughly enjoyable. little bit of tail tuning but otherwise a solid performer. i printed out the stiffer version just have to transfer over the parts, but i may just build up another and see if it's temperament is the same. superstitious when it comes disrupting a well working craft.
thanks again for providing the files. i'm working on a mod just waiting on more servos.
If you have any areas of improvement, I'm all ears. (Can PM me too)
Also I have been considering adding a dedicated camera mount to the frame. With the current release, a camera has to be mounted directly over the FC, adding both weight and vibration to the combined stack.
What I propose is one of the following.
Option #1, Small platform forward of the Flight controller, thats just big enough for a 0 - 30 degree tilted 20 mm Camera. Did this earlier on Tricopter Whirlygig frames and it worked well. This has the advantage of front-loading the CG a bit by making the camera directly upfront.
Note: Front-Loading the CG keeps more of the copters weight off the tail, making Yaw easier to manage / tune. Normally with a balenced CG the tail motors works the hardest of all three motors. (during forward flight) Pushing the CG forward spreads / shares the motor load better. Resulting in smoother flight.
Option #2, Elevated / seperate platform above the FC. This would allow the Camera and FC components to be stacked right over each other without directly touching. The platform would be supported from three sides (think Triangle) and act to shield the FC during a crash.
Option #3, Combined 1 & 2... This would allow the Camera to be mounted forward, while still having the elevated platform to mount other hardware. This would give the greatest number of camera options as well as add some extra stiffness to the frame.
Here is a preview that I have not released yet. (3" frame shown) This is option "three" which came out really nice. Obviously this would be for the 3-4S builds and not the 2S as they simply dont have the thrust. Dont get me wrong, not saying it's impossible etc.
Now assuming there is demand for it, I do have the means to easily add this to the 2" frame as well. Would take all of 10 minutes to do.
As always, your thoughts and comments are welcome.

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..
