User’s Manual for Roto 85 FS Engine
Congratulations on purchasing the four stroke engine ROTO,
manufactured exclusively in the Czech Republic.
You have purchased a new four stroke twin cylinder gasoline engine. It is important to
follow a few necessary steps to insure a successful first start in your model airplane.
Since the engine has been started and tested by the manufacturer, it will perform as
required.
The engine has been adjusted and tested with an attached 25/10 propeller and the ROTO
FS exhaust.
Packaging content:
Engine 1 piece
Ignition 1 piece
Sparkplug wrench 1 piece
Silicon hose 2 pieces
Tie straps 4 pieces
Engine Mounting
For mounting the engine inside the model airplane,we recommend using 5mm high strength
steel bolts, large flat washers and lock nuts.
Warning!
Check the engine mounting for tightness periodically.
Exhaust
The elbows of the exhaust can rotate. As soon as the desired position is achieved, the center
19 mm bolt can be tightened to fix them in place.
Warning!
Do not damage the exhaust elbows ends! The extension pieces that can be attached to them
might not seal properly.
The silicon hose is used to seal the joint between the exhaust elbows and the ROTO FS
exhaust pipes or between the extension piece and the ROTO FS exhaust pipe. The
extension piece and the ROTO FS exhaust pipe are not part of the packaging !
Use the included tie straps on both ends of the silicon hose to connect the extension piece or
the exhaust pipe.
