"AND, another problem with fixed pitch props is that thrust is directly controlled by speed (in fact, you have ESC) instead of angle of attack in the edge of the prop (variable pitch). Thats why: - 1st - you need huge speeds for big thrust - 2nd -…"

"Engineer here (and spanish too!) Fixed pitch props are not useful because [edge length / thrust] ratio is not lineal, but exponential. That's why you don't double the thrust when doubling prop size. Physics rule here :) no matter what RC…"

"An amazing project! However, I'm recently playing with a smaller long endurance build and I'd think that at 67" prop size you could achieve 3 hours and more with just standard electric batteries."

3hr 10min endurance test with HYBRiX quadrotor by Quaternium

Posted on December 14, 2015 at 11:30am 34 Comments

I want to share our last experience with HYBRiX, a lapse time of a 3hr and 10min endurance flight test. As far as I know it is the longest flight time for a hybrid fuel-electric drone, and I have to say it is not a lab test, but the same configuration we will start selling very soon. We are really excited about this! Please comments…

Successful flight test of hybrid gas+electric VTOL UAV: HYBRiX

Posted on November 18, 2015 at 12:00pm 43 Comments

This is the crazy project that kept us busy lately at Quaternium: a hybrid electric+gas multirotor with range extender, inspired by Hybrid cars, such as BMWi3.

Our goal is to overcome the endurance limitations of an electric multicopter, while keeping the multirotor platform we are so enthusiastic about. This VTOL UAV has 2.5 hr estimated flight time with payload, and around 4 hours endurance…

Huge quadcopters can be attractive alternative to fixed wing for mapping and survey

Posted on August 18, 2014 at 1:00pm 60 Comments

The sUAS market for surveying applications are dominated by fixed-wing aircraft instead of multicopters. The reason is obvious, the multicopters have very short flight time and can not run long flight…

My setup to use droidplanner

Posted on June 13, 2014 at 11:54am 19 Comments

I am designing this TX mod to use Droidplanner with big phones or tablets. I am planning to use for photogrametry with multicopters and planes.



I use mavlink telemetry through gitsly/openLRSng (…

Probably the smallest arducopter frame?

Posted on November 4, 2013 at 3:12pm 40 Comments

A long long time since I published last time, I'm drawing something fun and I thought you would like to see it!

It is a small frame all cnc machined from delrin sheet for 5" propellers. It seems a crazy project but…
