Im living in Switzerland and have a 200R3 that I made a new exhaust for and thought I would share. The ring and pipe are steel, the silencer is a KS 73/20 KS-5. Its really quiet and sounds extrelmly scale in the air.

Prop is a Mejzlik 18x6, current fuel is Graupner SX10.

Some numbers: on Optifuel 20% nitro it idles at 1000 and spins the 18x6 to 8700 on the ground
on the current fuel (Graupner SX10, 10% nitro, 12% oil) it idles at 1200 and revs to 8500

I prefer flying with the SX10 as there is less of a smoke trail and the engine runs much longer on a tank of fuel. The engine has about 20 liters of fuel through it now and runs like a champ. I broke it in on 20/20 and an APC 16x8 fand used the 20/20 for the first 10 liters.
Cheers,
Dave
