Welcome to the home of the OBLIVION 300+ remote control helicopter. This is a non-commercial website about a custom-built micro helicopter with high performance 3D flight capabilities. NOTE: This site is work in progress and the helicopter is still at design stage!

UPDATES

Ho-ho-ho!

Christmas is always more fun with presents, so here you go:

Added new xmas_v1.4.zip on www.oblivion-heli.com/index.php/getting-started/ containing
- New SLS printable tail blades
- SLS printable canopy
- Re-designed heavy duty rotor head, eliminates the need for additional 1mm shim
- New and lighter tail fin
- Modified head linkages to fit 2.5mm bearings
- Servo adapter plates for Spektrum H3050
Special thanks to Jonas for his contributions!

Just in time for the Shapeways 25% off Strong & Flexible on December 25th. Have fun everyone!

New video showcasing a bunch of Oblivions at the traditional 'Plätzchenfliegen' in Karlsruhe:

Bad stuff happens. I recently got myself some EDGE 253 rotorblades for my Oblivion and (of course) took them out for night flying. To wrap it up, I pushed a little too hard and learned, that half-frozen fingers tend to react a little slow. :)

The good thing about this mishap? It once again showed the awesomeness of SLS plastic. Even though the main blades hit the ground at 3000 rpm, they didn't take any damage. The blade grips took all the energy and snapped, saving my new EDGE blades and the rest of the helicopter.

3D printing is also called rapid prototyping for a good reason. A couple weeks ago I was talking to Tom Mead, who was one of the first to build an Oblivion on his own.
He still didn't have a canopy for his heli, so I brought up the idea of printing a cano in one piece. After some discussion about wall thickness etc, Tom volunteered to do some pioneering, a file was sent to Tom and a little later, a laser-sintered canopy made its way to the United Kingdom.
Here's the result, thank you Tom trying this out! :)

When it comes to rotor blades, everyone has their own personal preference. This is why I tend to try out every 250 blade I can get my hands on, to see whether or not it matches my flying style. A friend had Zeal Energy with him, so I thought, why not give them a shot on the Oblivion?

They definitely are made for high RPM as they are a little on the heavy side, but overall, they feel pretty stable and linear.

Here's a video of me trying them out :)

INTRODUCTION

A few things had to come together for this project to turn into reality. First off, noticing the precision, strength and weight of SLS (Selective Laser Sintering) plastic. When Andy Rummer first showed me a piece of this material, it immediately became clear to me that it has everything to perform great in rc-helicopters. It is all a matter of proper dimensioning. Secondly, my passion for the 300 size since 13 years and the conviction that 5.000 RPM headspeed is not the solution. Discload matters. Finally, the thought of combining all best practices i have learned and seen in rc-helicopters into one model of this forgotten class – and making it easily accessible to everyone: The Oblivion 300+.

In more detail: The design goal is a 300ish size helicopter that would lock in nicely on pitch and provides full 3D capabilities – all at 2.200 RPM. This results in less mechanical wear, lower noise level and light-footed flight characteristics. You will dare more with the Oblivion than you will with other models. Furthermore, this is a non-commercial project. Which means all drawings and 3D files will be publicly available in STL format. Practically anyone can send them off to Shapeways.com or other SLS services for printing which has a low price tag. Please note that regular 3D printers will most likely not produce parts that will work for this purpose, simply because of weight and tensile strength.

Key design aspects are: 140° heavy duty swashplate for equal travel of each servo. More important in the micro-helicopter domain, since the choice of high-speed servos is pretty limited. Three-point guidance for main shaft to allow for maximum frame strength and least amount of torsion towards the tail boom. 12mm carbon tail boom which essentially eliminates the need for additional boom support. Mono-frame – mounting a swashplate guide? 10 or more parts to build a frame? Not needed, since the frame and all struts are a single piece of plastic. 17 bearings, including thrust bearings for main rotor. Low disc-load of around 1.36kg/m2.

STATUS QUO

I am still at the design stage, and only a few prototype helicopters exist today. The core rotor system also works on a different chassis and performs flawlessly. I am going to post updates on here as we move ahead with development.

I would like to thank Jonas Wackershauser, Andy Rummer, Dennis Meyer & Ralf Bartikowski for their support and contributions to this project. Thumbs up! 😉

ABOUT ME

My name is Christian Ruck and i have been flying rc-helicopters and planes for quite some time now. I also run www.microheli.net, a website especially for micro helicopters. I am not a team pilot, tied to or biased by any particular manufacturer. The Oblivion is a personal and non-commercial project, essentially about finally building the model I feel is missing in the market.
