ROTO motor 170 FS is four cylinder 4 stroke gasoline engine made specifically for the model airplanes up to 4 m (13,1’) and 30 kg (66,2 lb). These dates are for recreational flying. The Engine was developed in Europe with the assistance of CAD systems (Solidworks) and optimized for the liquid flow in the Flow software (made by Solidworks). All ROTO engines and its components are made and programed by utilizing the state of art 5 axis machinery made by American companies HASS and Siemens NX. Every engine, made by ROTO MOTOR Company is bench tested and adjusted by qualified technician on the Engine Star equipment to ensure its peak performance. Basic technical data: * DISPLACEMENT 170 ccm * STATIC ENGINE THRUST 20 kg * WEIGHT 4 500g * BEARINGS Ball and needle * INGNITION PROCESSOR ROTO * FUELGAS + OIL MOTUL 800 1:40 * RPM 600 - 5500 * 2 BLADE PROPELLER 30/10-12 * 3 BLADE PROPELLER 28/10-12
I always wonder about the rear cylinders getting enough cooling air with the front cylinders in the way. V twins have the same question. The old VW air-cooled engines had ducting to cool all cylinders from above.
As a pilot myself my lil Cessna I fly the rear 2 cylinders always run a little hotter then front 2. Nothing to worry about though unless it gets into the red but I always like to keep my eye on them just in case
Really beautifull ! But, what about it's mechanics ? What about "fire" sequence, are opposit pistons moving toward the same direction, or in opposit direction ? ( a crank for two rods, isn'it ? ). What about distribution, typical rods and valves, or any electronic stuff ? Thank you very much in advance ...
Hello Morris Mini Motors ltd. May I use your content for my RU-vid videos i would like to promote your engine and company on my channel Thank you..... best wishes for your company ❤️
@@173shatta Or, in this case 42.5cc X 4 cylinders = 170cc Thanks, I'm new to these very cool engines and thinking about alternative uses. This engine should have brutal torque for its small displacement. Although specifically designed to turn an aircraft propeller, this torque could be lots of fun for applications normally powered by 1 cylinder engines like the 212cc harbor freight engine. Obviously, cost would be a huge factor, but if you want grunt with small displacement these engines are very cool indeed!
