Shen Arkangel 20 hybrid 5"/4"

By theGreenOrange on Nov 26, 2017

10 528 9

This is a bit of an experiment. It is a stretched plus hybrid with 5" props on 1806-2600kv front and back, but 4" props on 1407-3600kv for left and right. I just finished the hardware last night, haven't set up betaflight yet.

I modified the pod a little to add a holder for the Tramp HV and printed it in Sainsmart TPU. The motor feet are the ones Andy Shen has on thingiverse. Some nylon hardware was dyed with RIT dye (really easy in 10 minutes with hot water from the coffee machine)

It came out to 186g dry weight. I will be flying with an 850mAh 4S initially, giving an AUW of 289g.

So what's the theory for going 4"/5"? Weight savings?

Really cool looking build btw.

Thanks, I am hoping it goes really fast and turns like crazy :D

It is an experiment with no real hypothesis. Just a gut feeling it may be a nice combo. 2 big props for power and pitch stability, 2 small ones for light weight and fast roll ability.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class!

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
