The aircraft was supplied as a kit for amateur construction with production starting in June 1982.[1] Design and development The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The B1-RD has a standard empty weight of 220 lb (100 kg). It has a cable-braced high-wing, single-seat, open cockpit, single engine in tractor engine configuration, and is equipped with conventional landing gear.[1] The aircraft is made from bolted together aluminum tubing with the wings and tail surfaces covered in Dacron sailcloth. Its 32 ft (9.8 m) span wing is cable-braced to a top surface inverted "V" kingpost. The wing is a single-surface airfoil with a double-surface wing covering optional. The controls are conventional three-axis, including Junkers-style flaperons. The main fuselage structure is an aluminum keel tube that runs from the tail, mounts the wings and then the engine at the front. The original standard engines were the 30 hp (22 kW) Cuyuna 430R and the 20 hp (15 kW) Cuyuna 215. The landing gear has bungee-suspension on all three wheels and the tailwheel is steerable.[1] Production of the B1-RD was curtailed circa 1984 due to liability concerns.[1] Variants In addition to the standard single-seat model, a two-seat version of the B1-RD was also marketed.[1] Specifications (B1-RD) Data from Cliche[1] General characteristics Crew: one Wingspan: 32 ft 0 in (9.75 m) Wing area: 162 sq ft (15.1 m2) Empty weight: 220 lb (100 kg) Gross weight: 500 lb (227 kg) Fuel capacity: 4 U.S. gallons (15 L; 3.3 imp gal) Powerplant: 1 × Cuyuna 430R two-cylinder, two-stroke aircraft engine, 30 hp (22 kW) Performance Maximum speed: 50 mph (80 km/h, 43 kn) Cruise speed: 38 mph (61 km/h, 33 kn) Stall speed: 15 mph (24 km/h, 13 kn) Never exceed speed: 75 mph (121 km/h, 65 kn) Range: 125 mi (201 km, 109 nmi) Service ceiling: 14,000 ft (4,300 m) g limits: +3/-2 Maximum glide ratio: 8.5:1 Rate of climb: 850 ft/min (4.3 m/s) Rate of sink: 300 ft/min (1.5 m/s) Ultralight Aircraft videos: Luke flying Robertson B1RD: https://www.youtube.com/watch?v=_j5fJ9lBXTs Mac Hodges in Sportster: https://www.youtube.com/watch?v=Vvanwh-LdAg Die Liebe Zu Dir: https://www.youtube.com/watch?v=oVmqH0SfLgc Ghost Plane: https://www.youtube.com/watch?v=aL4HokEhhCI Starshop: https://www.youtube.com/watch?v=HLA9xiU7Sv8 Dark Horse: https://www.youtube.com/watch?v=879JA4okBvg Apparition of Freedom: https://www.youtube.com/watch?v=ETnZIqmKMcc Wild Ultracruisers: https://www.youtube.com/watch?v=CkFM6r2eq7Q VJ-24w Hodges Field: https://www.youtube.com/watch?v=_wU0_Qb8qo0 Volmer Jensen: https://www.youtube.com/watch?v=Vy9GowNBgus Hans Grade Monoplane: https://www.youtube.com/watch?v=eNZa28o4jLQ You make my Dreams COme True: https://www.youtube.com/watch?v=ED6DNEsG0Mc Poorboy Ultralight: https://www.youtube.com/watch?v=JQxof-vJapM Poorboy Ultralight Water Tirp:https://www.youtube.com/watch?v=sGKBIuqTNxE Chotia WOodhopper: https://www.youtube.com/watch?v=Lm4NSX595_s Chotia Woodhopper #2: https://www.youtube.com/watch?v=lJL48s90smc Russian Peaches: https://www.youtube.com/watch?v=mnjG3qefzmg Another TIme ANother Age: https://www.youtube.com/watch?v=4qTx4dto5y4 Greg's Northrop GLider: https://www.youtube.com/watch?v=imAKYa_pzw8 Fireworks Bridges: https://www.youtube.com/watch?v=tjs2VQ6P5iE Unchained Melody VJ-24w:https://www.youtube.com/watch?v=lJL48s90smc
