Electrics / New to the forum from the midlands.

Howdy,

I just thought, I'd introduce myself. New to the forum, not so new to the hobby.

Started out with electrical helis in my childhood, left the hobby for many years, then got the interest again a bit over 10 years ago. The main reason, I got back to the hobby was my interest for aerial photography.

Either way: to lift a cam, a nitro heli was necessary. And lugging that around wasn't always convenient.

About 2 years ago, I sold my nitro heli and moved on to multirotors. I still have an electrical heli, but it's more of a toy. Might get myself a nitro heli again eventually.

Currently, I've got the electric heli, a nitro truck and 2 quadcopters. I recently sold the 3rd I had, as I'm upgrading for a hexa. I've also backed 4 multirotor kickstarters in the last 2 years, of which the first 2 of them only just now are about to be shipped. I've got another 2 rotor camera platform on preorder.

I love gadgets. And I love messing with technology. Exploring new avenues . Recently, I managed to modify one of my quads to a point, where I was flying it using 3G/LTE opposed to it's regular controller. Imagine the possibilities.

Electrics / RTE - The Do's and Don'ts of "drones"

Ah sure. At least that one is objective.

Have a search on the "Game of Drones" article in the irish times last year, which is completely and utterly out of concept and full of misconceptions.

Nitro / 2-stroke quad

Howdy,

Multirotors with IC engines have always been an issue, because it's not easy to sync/stabilize the engines with eachother.

Well, there's a german company, that seems to have solved this:

Here's the video from the evolution of their quadcopter:

What they've done is taken 4 nitro engines, that can be converted to 2-stroke. They also have fitted 4 BLDC engines. So one BLDC and one 2-stroke 10cc engine per rotor.

The BLDC engines are used to start the IC engine. They also help controlling and adding accuracy to the rotor, they serve as alternators for the LiPO that powers the onboard electrics and they act as emergency engine, should the IC engine fail.

The project was set up as Kickstarter project and has been funded.

Specification is that it weighs 4.9 kg, is capable of a 5 kg payload, top speed of 100 km/h, range 55 km (2 km from remote) and flight time between fueling of 60 minutes.

To prove it's capabilities, they decided to let it lift a beer keg That video can be found in the campaign under updates.

Thought it might interest some people here. I actually have backed the project, so looking forward to getting my IC quad next year, if all goes well.
