The combat engine F2D 15.Top 2007

Characteristics:

• MAX RPM 35000
• Volume 2.48 sm.cube
• Bore 15 mm
• Stroke 14 mm
• Piston/liner : Aluminium/DISPAL 226 (30%Si)
• Crank valve 13 mm, inside hole diameter 10 mm with turbo-output a mix
• The rear bearing - the combined support the shaft/bearing 12х21х5 mm of the Swiss manufacture
• The front bearing 6х15х5 mm with the increased backlashes (18…25 micrometers) a high class of accuracy provides fast start of a motor in the winter
• The increased length of a connecting rod (29 mm) increases resource and torque of a motor and as lowers temperature of a motor that allows a motor to fly to a hot weather without loss of power
• Ventury diameter 4 mm
• Weight 109 g.
• Recommended glow plugs – Nelson HD, Nelson HD Ceramic, Nelson Glow Bee

Why revolve a silencer under a wing:

• Exhaust gases do not get in model through a groove under thrust of a control surface
• Exhaust gases do not get in the container of a dummy
• Fuel does not fill in a motor after landing, and follows through a silencer
• It is less probability of fire of model at a unsuccessful flash as fuel follows not on model
• The heated exhaust gases do not burn a hand at adjustment of a needle and service of a tape
• The strong silencer maintains landing to maximum speed and executes a role of a landing ski
• It is less noise for mechanics
• There was symmetrical a cooling of the cylinder of a motor as the stream behind a propeller is twirled in the same party, as a silencer (on a conventional silencer - a stream across a silencer that causes overheating a back wall of the cylinder)
• Allows to use models with easier tail (stability and a manoeuvrability of model) is higher As there is no finning of the head biased back and a motor it is possible to push further back about 5 mm
