The question to ask is would you send an average pilot solo in a Duo?

It is much slipperier than the K-21 so subtle changes in attitude result in= much larger changes in speed. Couple this with the lack of noise and pilot= s were finding themselves over 70 kts on final. It carries more energy into the landing than does a K-21, although the addi= tion of landing flaps to the XL version resolves much of this. Besides its handling and performance, another nice advantage is the sideway= s opening canopy does not result in burn marks on the instrument panel in t= he front and headrest in the back. We've sent an S3 vario back 2 times for= screen replacement because of sun burns that happen almost instantly when = the sun is in the worst possible spot for a K-21.  |
