Built this up for a friend who wanted to try something really different yet didn't want to skimp on performance.
Note: The frame is completely custom of my own design so if your interested please PM me.
This Tricopter runs Betaflight 4.1 with motor filtering and has an attached Openlagger.
Weighing in at 142 grams with the 4S battery shown.
Thanks to the Emax 1108 motors, it boost a very nice TWR of 6 to 8:1. (Hovers around 12-15%)
I guestimate that just farting around you'll see a flight time of 4-6 minutes but full on crazy Acro may last 2-3.
Please be aware that I live in the EU so my over all cost is closer to $300 - 350.
Here is the video from it's sister craft (3" 2S Tricopter Whirlygig)

Post a video! I'd love to see it running
Its been shipped off but I'll attach the step-response so you can see how the in-house tuning went.
Only issue with this design is that Betaflight doesnt have much in the way of servo support. A while back we had Triflight, which was BF modified to allow for the servo endpoint claibration and in-flight tail tune. I'm hopeing that soon this will change and thus allow for better Yaw prediction.

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..

where you plug your servo ? i try to make the same setup but servo fuck me up tank's
Try remapping the LED pad for use with a Servo. Be aware that with Betaflight that the resource mapping can change from one flight controller to the next.
Aslo, do NOT use the Betaflight default PID's unless you want the copter to launch into the ceiling. The special fuctions like Anti-Gravity shjould also be avoided when first tuning as they will alter the PID's in flight making it harder to diagnose and make the correct changes for smooth flight.
tanks that was what i was thinking about but wasent shure led can output pwm
led output u already got grn 5v and signal
I use the LED pad (remapped via Betaflight CLI for PWM), then the voltage tapped directly from the LiPo 2S battery. The battery is 7.4 volts and thus is ideal to use as the Servo source power. Just be sure to add a capacitor across so that voltage transients don't mess with then smoothness of the Servo. (100 uF @ 16v should do nicely)
