The engines Top3 and Òîð4 1.0 cm3 are created by us specially for small timer model FAI F1J (F1P).
Fine start and high capacity Top4 (0.65 BHP on 41000RPM). Have made its World champion 2000 and 2002 (29500RPM on the ground)! On our data - the maximal moment at 36000RPM.
At weight of 67 g. it does not demand a engine mount - a back flange specially for fastening at once on model.
Carefully picked up temperature mode of the motor allows to work stably practically in any weather. And rigid corner - plastic the one-blade the propeller gives good starting draft and the big height in 200...250 meters.
Small ìàñà rotating parts does not demand mechanical braking of a shaft at the end of motor flight - to pour up fuel from the power supply system such as «dummy» under pressure 1 àòì instantly stops the motor, and dumps a superfluous fuel ballast.
Easily maintains fuel from 65% Ni (oil - aviamodelling synthetics such as KLOTZ since castor oil is not dissolved).
There is available new high - precision (Germany) radical bearings 9õ17õ4 mm with a firm textolite separator and increased (Ñ5) a radial backlash 18-25 microns. Is available front bearings with increased radial backlash (Ñ5). The engine, after simple adjustment of a degree of compression, with such bearings twists more on 1000 RPM in a range of revolutions (on different propellers) from 29000 up to 43000, and disperses model at the end of motor flight more strongly. The bearing road, but «worth powder and shot».
