ABS original manufactures, in France - Hirth engine - maybe 15 kits sold
CA formed and production moved to Jaktorow, Poland - Xenon 2 with Rotax engine sells well, up to approx ship #150
CA dissolve circa 2011/2012 - partners becomes AAT ( Aviation Artur Trendak ) and "new CA" - AAT remains at Jaktorow with tooling and staff and continues building from approx ship #150 onwards initially as Zen1 and later refined Tercel - over 100 built to date by AAT, still active today with current production now at approx ship #275
"New CA" sets up new production line but moves severla times - ends up in Piotrokow Trybunal, Poland taking parts from MBL - builds three Xenon 2 and then approx twenty examples of refined Xenon IV - "New CA" moves on to Malta, no production known.
Fly Argo offers CA Xenon IV product and now appears to offer to build new Xenon IVs as Argo 915 - no deliveries known
Air Gyro USA originally a dealer for AAT ( imported several Tercels into USA ) now offers AG915 and confirms this will be parts supplied by MBL for kit building in US with a Rotax 915 - as yet no AG915 kits in USA, three kits said to be en route - marketing shows a modified Celier built Xenon IV SP-XNON ( built 2016 ) now fitted with a 915 flying in Poland being used to promote AG915.
That's my understanding but corrections, updates welcom, good luck making your choice
Of the ABS (Xenon gen 1) machines only 1 was in the US and it is not still flying. Not sure about the others sold in France but the Hirth engine had many failures.
I was the initial US importer for the second generation Xenons made in the AAT factory in Poland in 2007-2008. The 10 gyros I imported are registered E-LSA and the only gyros registered that way. Others were later brought in as Experimental and these are mostly Generation 3 Zen/Tercels. After the split between Artur Trendak and Raphael Celier CA moved around 3-4 times but each time his partners kicked him out as Artur Trendak had. Raphael Celier ripped off people in about 5 different countries and never provided support for most of stuff he sold. Steer clear of him
AAT has not had very consistent US representation. I was the first US rep and sold 10 gyros in less than a year, followed by Mike Bantum for 3-4 years even though he only sold 1-2 gyros. Chris Lord repped both AAT and Celier for a time. The AAT factory is good but it would be far better if you could work with a US rep for parts and service etc.
