Engine mount


The standard Lorenz soft mount was used. It’s just four rubbers attached to a glass/epoxy plate plus a fibre-filled glass mount. 

New 170 cdi, 110 FS-a


From Japan comes new stuff – Masahiros hobby world reports from the 2008 Shizuoka model show and brings info of a new O.S 1.10 FS-a fourstroke, as well as a Hirobo Aries F3A model and the YS answer to the O.S 200 EFI engine: A YS 170 DZ with electronic ignition. Speculation runs wild on RCU but sources say this is a glow engine with more power and reliability coupled with half the fuel and oil consumption.

New engines coming


You can always trust O.S to be at the forefront of engine development.  Go to http://www.os-engines.co.jp/english/index.htm and feast your eyes on the perfect little .35 AX and the 200 pumper.  
I gotta have both. How does one get by without them?

O.S. 200 FS

Smokin!

New O.S fourbangers

No it’s not the standard unpumped version, and not the shamefully expensive EFI. It’s a 200 FS pumped, with a new pump and fuel regulator. Should be a fantastic alternative to the YS 1.70 for people on a budget (me), people who love O.S engines (me) and people not wanting to run the 30% nitro fuel that YS requires (me also…) Have a look at this video from RC Universe (21 MB .vmw)

Also new from OS is the .81 FS-a, replacing the .70 surpass. The .81 is a new development but fits in the same bolt-pattern as the old 70. And there I was thinking to myself “what would be the perfect engine for a glow-conversion of the Sebart Angel S 50?”… And whaddayaknow, some engine company in Japan makes just such an engine :-)

New O.S engines announced at Toledo show


Foto: RC Universe
O.S engines continues to innovate rather than duplicate, as is so popular with engine makers these days. Another good reason to fly O.S!

Fresh reports from the Toledo model show are posted at RC universe and I’m pleased to see an all-new O.S .75 AX two stroke which should bring great joy to all those underpowered .60 size planes that think a .90 is too much!

Even more spectacular is the fact that the four-stroke lineup known as Surpass will gradually be replaced by the “FSa”: The “a” stands for “Alpha”, of which the .56 is the first.

Read the full Toledo coverage at RC Universe and look to OS engines homepage for detailed specs on the FSa-56.

Pichler Modellbau sell cheap pattern engines

Yes, they are very cheap indeed! Although not designated pattern engines if you compare them to a 1.40 RX, the new 1.30 and 1.40 engines still have CC enough to power a lot of 2-meter models if you want to get into the air without a mortgage.

The 1.40 (23 ccm) weighs just 650 grams and costs not more than 159,- EUR.

Pichler sell a whole range of these blue two strokes and the sizes are:

  • .JBA .39AR
  • JBA .40A
  • JBA .46A
  • JBA .56AR
  • JBA .61A
  • JBA .91AR
  • JBA 1.10AR
  • JBA 1.20AR
  • JBA 1.30AR
  • JBA 1.40AR

If you can’t find a size fitting your airframe in that lineup you will not find it, ever!

Thunder Tiger 1.20 reloaded

According to the April edition of the German Modell magazine, Thunder Tiger presented two new 1.20 engines at Nuremberg, one with side-exhaust and one rear exhaust. Apparently, they are quite unique and feature a cylinder which is screwed into a socket in the main case, lightbulb-style

Forget I said that – I was wrong :-)
I re-read the article today with fresh eyes and saw that the lightbulb-sockets are the cylinder heads and not the cylinder itself, and it was the all -new GP .18 and GP .28 engines, not the 1.20. Still, the article does say the 1.20 is “new” and that it comes in both side and rear-exhaust versions. I can find no other source of information but it’s not likely that the old 1.20 from the 1990′s is being launched in Germany for the first time in 2007 so the engines must be reworked somehow.
