Here’s a short sequence showing some of the planes of the day. In 2005 I still flew the Calypso in the Nordic schedule. In the video you can see an Impulse, Temptation, Synergy 50 and many more.

Integral CDi conversion
January 2, 2010 – 20:42
The Integral is finally ready. The YS 170 is converted to CDi and as soon as the weather is warmer I will run and tune the engine so it’s ready for the next season of P-11. I’m now using Futaba FASST 2.4 GHz to avoid ignition noise so hopefully I’m immune to radio interference. Ignition is controlled using a Turnigy transmitter operated switch which seems very safe and easy to operate.

New plane: Integral
November 12, 2009 – 16:30
New plane in da house! I’ve bought a brand new, ready built ZN Line Integral. Masterly built and painted by Rune Gjelsnes who is now well on his way to financing the switch to electric F3A. It has a used Ys 170 for power but will be rebuilt with CDi conversion kit before I fly it. It has an anhedral stab and removeable canalizer. More pictures here
Laser with YS 170
September 7, 2009 – 19:53
Although it happened a little while ago now, here’s the status on the blue Laser. It’s been fitted with a used YS 170DZ/Hatori combo and thanks to my buddy Audun it ran very smooth. I had three great flights at Auduns field and I was very pleasantly surprised to experience the immense braking effect on downlines with such a powerful engine. Fuel consumption… not so impressed 
I have enough for a schedule but no more so I need to be careful. I’m very happy with the choice to standardize on YS engines. That’s Auduns Oxalys in the picture, the plane used to belong to Ola Fremming. Audun was unfortunate and broke his belly pan during a forced landing. Pictures here
OS 61 FX nostalgia
August 20, 2009 – 07:00
I sold the F3A Calypso and I had to run the engine just one last time. Freshly overhauled and with new bearings, it runs like nothing else matters. Beautiful. Love O.S.!
PS – I know I’m an idiot for holding the camera crooked AND holding the camera in the propwash at full throttle…
Laser/OS 200 first flight video
July 28, 2009 – 17:40
This is a really nice video filmed by my friend Audun Thinn. It shows the first flight of the blue Lorenz Laser, powered by the OS 200 FS with an added Perry pump. The exhaust is a Hatori #824 pipe. The engine runs rough and rich and finally dies but the plane lands safely. The 200 failed to perform as hoped after break-in and was sold in July 2009, will be replaced very soon by a YS 1.60 DZ. A larger version of the video can be found on Youtube
Mid-season status update
July 23, 2009 – 17:01
I have been quiet here on the blog but very actively practicing and tuning models. Here’s a quick update on how me and my planes are doing.
The red Laser (OS 160) is performing extremely well. A better manifold (thank you Just Engines) and shorter pipe lenght has produced more power and it now pulls the 18×10 APC at a steady 8300. The idle RPM is comfortable at 1500 but possible to get down to 1300 (!). That said, I have made a decision to sell it and make the switch to YS fourstrokes entirely, because…
The blue Laser (OS 200 FS) is not performing like I had hoped, reaching only 7500 rpm on an 18×10 and being sluggish in the air. I have decided to sell the engine and swap it for a used YS 160 that a friend of mine sold me. So now that I’m a proud and slightly apprehensive YS owner, having never owned or operated one before I have made another bold move…:
I have made a deal to purchase a ZN line Integral complete with YS 170 from an F3A pilot who’s switching to electrics. The plane is just ready built and complete but not yet flown. Sometimes you just have to jump on a chance to get a professionally built plane like this. I’m hoping to get some flights on it at the end of this season when I get in in a month or so and that it’ll be my new primary model.
Mini Scalar first flight
June 24, 2009 – 13:46
I finally got to fly the Mini Scalar that I spent the winter assembling and painting. The plane flew surprisingly well, requiring just two clicks of aileron trim. Surprising is putting it mildly, since I had to set up all incidences myself, my first time ever doing so. Nothing beats beginners luck. The plane is overpowered to say the least. I have never had a plane this powerful, ever. the 6s 4000mah battery was a good match and has enough power for two schedules pr. flight. I’m happy to have a new favourite practice plane for those quick out-to-the-field-before-wife-notices practice sessions. But I need more batteries, can’t stand waiting for them to charge at the field. And no, the props is not broken – it’s an Aeronaut folding 14×10 propeller, something that proved to be less than clever when used in combination with a motor brake on the ESC. A fixed prop is now on order, this plane really needs to slow down on the downlines and you can imagine how fast it is when the motor brakes – the prop folds and you have less, not more drag!
Blue Laser ready
June 7, 2009 – 18:53
The second Laser is ready to fly. I’m not sure about the weight but it should be lighter than it’s red sibling.
Here’s the list of goodies:
- OS 2.0 FS w/ Perry pump
- Hatori header and pipe
- Emcotec DPSI-mini RV dual magnetic switch w/regulator
- 2x Kokam 800Mah LiPo
- Graupner SMC-16 Scan SPCM receiver
- Hitec Servos
- Tettra 560ml Crank tank
It balanced perfecly without any adjustments. The spinner from Dave Brown will be substituted for a light backplate tru-turn after the next Central Hobbies order. And on tuesday this week, it flies. Wish me luck.

Laser progress
August 31, 2008 – 19:16
It’s amazing what can happen in 30 minutes in the workshop. Suddenly several evenings worth of fitting, adjusting, drilling, grinding, fitting, throwing away, grinding more and even gnashing of teeth came together on one go. Once you decide that a good fit is good enough, go for it. And the damned thing fit like a glove. This was just a dry-run, gluing and fuelproofing comes later. And when that’s done, I don’t know what’s left. Fly maybe?
Here’s the tail linkages. Done with that too. There’s a good lad.
