I have 9.4 hours in a Remos GX, most recently from a short cross-country trip this past weekend. I'm very curious to see what the NTSB has to say.
The story I've heard is that he reported elevator control failure and the airplane was very difficult to control. It's not clear whether the airplane had a BRS chute installed. I base my statement on trusted sources local to the area, not on the media reports.
The early reports about elevator control failure (since amended in recent reports to unspecified 'mechanical' problems) are troubling. The Remos is equipped with a detachable horizontal stabilizer, with two sturdy through-bolts holding it to the tail and a robust quick-connector linking the elevator to the control pushrod. Similar connectors are also used on the aileron pushrods for the folding wings; a fatal accident at Sebring 2009 was determined to have been caused by one of these aileron connectors not being secured prior to the flight.
I've attached a pic of the aileron connector; the elevator connector uses the same design, with the same locking tab (visible at the top) to verify it is fastened correctly. It's fairly easy to inspect the elevator connector during preflight, by moving the rudder to one side and looking down at the assembly. It helps to have a flashlight.
Something I haven't been able to verify yet, is in what phase of flight this accident occurred. A failure on takeoff would be a bit easier to understand versus having this happen following a longer flight.
I've sat in a Remos GX. It's cramped. I've flown a Tecnam Sierra. It's cramped.
All LSA are cramped, but the Remos is one aircraft I'm actually pretty comfortable in at 5'11" and packing a lot more pounds than I should be. (Pete Zaitcev, who's much thinner and much taller than I am, also flies N28GX on occasion, and he's said it's a tight fit for him.) The most glaring ergonomic issue is the need to crane your neck down to see out the side windows, as the wing root and upper door frames are right at eye level.
Also, he was found 50' away still strapped in his seat? How common is that in airplane crashes? So much for a roll cage.
Both seats in the Remos are removable -- you must unlatch them from the support frame to reposition them, and to access the baggage compartment behind the left seat -- with the four-point harnesses secured to the fuselage. Judging by the photos it would appear the passenger cell essentially disintegrated on impact.
