81 " PBY-5A Catalina
The 81" PBY-5A Catalina is the most popular of my seaplanes. It is scale except for a 10% increase in bow length for good water handling and a 10% increase in vertical fin height for better lateral stability in flight.
The wing has a flat bottom high lift airfoil which provides good landing characteristics. The semi-symmetrical air foil of the original airplane necessitates a high airspeed and makes landing very difficult, hence the change. It has a wide speed range making is safe to fly as well as the ability to fly slow at a realistic speed. It will do loops and rolls and will climb moderately on one engine (using 2 Fox .40s). I have maintained altitude and made go arounds on 1 engine with ease.
This plane is a great twin engine trainer. With the engines mounted so closely together it does not snap roll like many other twins with one engine out. It slides sideways on one engine and some rudder and aileron will turn it against the dead engine.
It comes with a 30 page step by step construction manual with full size drawings of the parts that are not already made in the kit. The wing is 1 piece which attaches to the fuselage pylon with two nylon wing bolts . The 4 lift struts are functional and attach to the fusleage and wing with #4 sheetmetal screws. It requires a 5 channel radio if retractable floats are used and requires 6 servos because there is a servo for each engine. The front of the fuselage has a hatch which is the vacuum formed cockpit and nose gunner turret all formed in one piece with the panel lines for the 26 windows that are embossed in the cockpit-turret. Cockpit, gunner turret and waist blisters are transparent acetate. The kit comes with fuselage halves joined and includes foam wing cores, all wood needed. Cowls and nacelles are vacuum formed of high impact 1/16 " styrene.
