VT 85 2R
The VT 85 2R is a two-cylinder four stroke
in-line gasoline engine, specially constructed for the use in narrow cowls
of large scale models. The compact construction is achieved by a camshaft
placed in the cylinder head with 4 ball bearings where the rocker arms are
actuated directly. It is driven by a timing belt placed at the backside of
the engine.
To avoid thermical problems of the rear cylinder in practical use, the cylinder-block
and the cylinder head are constructed as a one-piece engine-part.
The crankshaft with an ignition angle of 180° is pivoted with 4 ball bearings
for a smooth run, a long life and a spontaneous speed-up reaction. High torque
is available from low engine speed up to maximum of rpm, combined with a reliable
idle run.
The two cylinders of the VT85 2R are fed by a walbro pump carburettor with
a choke flap;
combined with a 4,8V electronic ignition-system with integrated ignition advance
the starting of the cold or hot engine is uncritical and easy to perform.
The VT 85 2R doesn`t need a special engine bearer; it is simply fixed at the
engine-dome using D-Locks and 5mm screws: A secure and simple assembly for
all fuselage-motor-frames.-
The mounting position can be chosen freely, either an upright, a horizontal
or a hanging position is suitable. –
As the connecting rods are equipped with needle bearings, a gasoline-oil-mix
of 30:1 is adequate.-
As a further option individual constructions of silencers are available; special
solutions for every model and every cowl are possible.
