Spectrum RX-550 Beaver
ASAP Beaver RX 550

A rugged, deluxe 2-place trainer and cross country Beaver RX550 has a 10.7 m wingspan, Rotax 503 47 hp engine and weighs 150 kgs. Both aircraft feature fibre-glass pilot fairing and windscreen as standard equipment.

In 1993, ASAP began providing parts and service for the existing Beaver RX550, RX28 and RX35 all aircraft manufactured by a company no longer operating. The demand to continue offering the Beaver aircraft as a kit was high and so in 1996 ASAP introduced the new Beaver RX 550 Plus with new wings, new tail, stronger shock system, better performance but still keeping with its famous docile easy flight of the original Beaver.

The prototype of the Beaver Plus first flew in 1995.
