ZK-JRC2 c/n 09 has been hangared at Ashburton for some time. Picture above taken on 21-03-2008.
The third is ZK-JRN c/n 10, which I have not yet sighted.
JRC & JRN are still both registered to the importer Maxim Vassiliev (East Sea Company).
The Sigma is Rotax 912ULS powered onto a Kiev, threee bladed propeller. They also have ballistic recovery parachutes. Pic above shows JQF coming together at Rangiora on 24-02-06 showing part of this system :the red object on rear window: which connects to the chute.
