Hi everyone,

I'm new in this forum and I do have a question about the MDS 40 engine. I've bought an older one of this type. It hasn't been use, but I don't have a data shett of it. Does anyone have an idea where I can download it or can anyone do me a scan of it?
Any tips to that engine? - Size of prop, kind of glow plug?
Any useful tip would be great!

Thanks Georg Quartier

P.S. Hope my english is not too bad - I'm from Germany

Use fuel with 5% nitro, 20% oil, a good quality four stroke plug such as an OS-f or Hangar 9 Super Plug, part #HAN 3011 not HAN3010 which many hobby shops are trying to tell people is the Super Plug, it is not. 10x6 prop, break it in a little rich but not much and run it fairly fast after about ten minutes below 6,000 rpm to get the rod run in.

Hi!
As you are from Europe as I'm, you will find that the Russian MDS engine works fine on low nitro (5-10%) and 15% all synthetic oil like Graupner Aerosynt 2 and Aerosave or The French Motul "micro" syntetic oil.
Castor oil could ofcourse be used but the engine will run better and hold up longer if you use only syntetic oil.
As for propeller: Always use the American APC line of props if you want good performance and if you want a fiberglas prop (As most flyers do nowadays). There are wooden props but these are not any better than the APC, only lighter (which could be good sometimes). Menz is one of the best woodprops.... but I don't think that they have as small props your'e looking for.
A 10x6 to 11x6 is perfect for a highwinged trainer aircraft like the Kyosho "Trainer" (at sea-level) and for most lowwinged sportaircraft.
Enya 3 or OS 8 are good glowplugs.
