The O.S engine gave me a little headache. I ran it at home a little bit, and it ran strong and started like any O.S motor should, i.e. with a light flip of the prop. It tached 10.000 rpm on the APC 11×12 and idled smoothly. All was well and then I tried holding the […]

Killer Kaos restomod part 3
The finished radio bay in the fuselage My favourite part of any build is the pushrod mechanicals, the electronics and engine installation and so I take my time getting it as perfect as I can. I ground out a huge cutout for the Tettra 400cc tank in the fuselage former. The tank would fit in front in the […]
Supra Fly 25 resurrection
I built an old Supra Fly 25 from the OK model kit in 2002, flew it with an O.S 40 LA, and stored it away when the engine was sold. I came upon a new-in-box O.S 32 SX engine in the summer of 2013, and I put two and two together, literally. What a match! […]
Curare update
The 2013 contest winning Curare ARF was badly treated. In order to win, I practiced intensely two days before the contest and ignored signs of worn bearings. The engine quit and I landed nose first into tall grass. Broken header, bad bearings, broken nose gear. With no time to spare I managed to patch the […]
Curare wins F3A retro contest
The Curare Trio: Me on the left with my Schweighofer Curare ARF (glow), Ingmar Svensson (middle, third place) with his scratchbuilt Curare, and Ola Maltesson on the right (5th place) with his new Schweighofer electric Curare. The Swedish/Norwegian border cup is back, and our Swedish neighbours hosted a three day F3A event at Lilla Anrås […]
Hanno Prettner Curare ARF part 3
The final part of the build is the engine and pipe setup. This is usually time consuming with a lot of alignment, but I found that not to be the case here. One evening, and you’re done! The firewall and tank area is 100 % ready from the factory, fully fuelproofed. Even the blind nuts […]
Hanno Prettner Curare ARF
Photo by Karlheinz Gatschnig, www.http://gatschnig.at I am doing a review of the new Hanno Prettner Curare ARF for our magazine, and since that magazine is in Norwegian, I’ll also post it here for a broader audience. The Model is produced by Modellsport Schweighofer in Austria. (It’s made in China exclusively for Schweighofer from their specifications). […]
Tiger 2 maiden flight
The Tiger 2 was flown for the first time today, and it was successful. I ran the engine for about a tank and a half on the ground, and after that it was well behaved. The O.S. .55 AX is the easiest engine I’ve come across. I just flipped the prop and it started just […]
Engines part four: Why won’t it run?
Everytime I go to the field someone has a “faulty” engine – one that won’t start, or that dies in flight or on takeoff for some reason. Or at least they think they do. Fact is, it’s hardly ever the engine. People say the wildest things: “The whole setup is gone” (meaning cylinder and piston) […]
Engines parts three: tuned pipes
A tuned pipe can increase engine power dramatically while at the same time reducing noise. Sounds too good to be true, but it requires a good setup and a pipe that matches your engine. You’ll also have to take into account that fuel consumption will be a lot higher.
