StarFlight kits, hand-made by experts in the Ukraine, have become famous for quality and value. The Pulsar 4.0PRO is a development of the popular Pulsar 4000, and has some significant improvements! They have added slight dihedral to the centre-section to improve handling in small thermals, and made the nose pod one piece with a hatch for easy access to your data logger - and ended up with a high-tech glider of maximum size for F5J and thermal hunting.
The wing is in three pieces with two flaps in the centre panel mounted on a slight pylon - split flaps are operated by two servos. This gives the ability to employ crow-braking for effective landing control (flap down, ailerons up, compensating elevator) PLUS flaps operating slightly as ailerons and aiding roll control. A well-tuned model with this feature is a delight to land on a chosen spot and to thermal in light conditions. Carbon/kevlar/balsa construction has been used throughout to give great strength with minimal weight. A D-box leading edge, carbon-capped ribs and carbon trailing edges are features of this model. Ailerons, flaps and rudder are pre-hinged with integral shrouds to cover the hinge gaps. This is magnificent construction! If you are looking for a large size, superior glider, beautifully constructed, at a reasonable price, you need look no further! This model has a cross-tail as illustrated and now employs an all-moving tail mounted on a carbon stand in front of the fin and rudder. Specifications are:

Recommended Settings: Ailerons - 15mm up, 6mm down Elevator - 15mm up, 10mm down Rudder - 35mm movement, mixed 80-100% with ailerons Flaps - maximum down Note - if flaps operate also as ailerons, the aileron movementr may be reduced - more efficient in light air. Very important: CofG recommended at 95-105mm Start with a forward CofG and move back slowly as you become used to the aircraft - Europeans usually set up their models very twitchy for light air flying, but that can be dangerous if you are not ready for it. Experiment carefully! I flew mine at 95mm back and tried the dive test - it pulled out slowly - I would not go any further back! |
