Look at the post-crash photos of Harrison Ford's mishap in his PT-22. Note the engine busted (or half busted) off the mount. I've never thought about it before, but after the subject came up I don't know that I'd want the engine behind me in a sudden-stop-crash scenario. I know a guy who was hit head -on in his van-- the impact didn't do him any damage to him. Too bad he can't say the same about the heavy toolbox in back which came flying forward into the back of his seat.

Think of them as very light weight -very powerful -light wing loading airplanes. There are "experimental cubs " for 1/2 or way less price that will do as much or more. I personally like Stinson 108-3's with 165-180 hp. hanging off firewall. Think in terms of Large wing area with low weight per sq. foot and Clark Y airfoil.

Many pushers are not registered aircraft (folks that skated the regs claiming ultralight "trainers"... of the 2 locals I witnessed, both were registered E-AB but when local sheriff calls the FAA he says "they look like ultralights..."...FAA says "we don't investigate ultralight incidents"...end of FAA/NTSB involvement. Folks were still dead. The math I was referring to was the laws of physics, not government paperwork.
And for full disclosure neither "wore a Rotax hat" but were killed by the structure ahead of the Rotax being pushed forward by the substantial kinetic energy of an engine being decelerated rapidly. The majority of common pusher aircraft (Challenger, RANS, CGS hawk, Drifter) all have aluminum tube structure between the engine and the pilot...Not nearly as crashworthy as chromoly steel. Titan and Kolb have CrMo structure but in the effort to keep it light, it is very small diameter and very thin. Titan had a service bulletin years ago for engine mount cracks from regular use...Not crashes, that had to be reinforced. Former Kolb manager/part owner Norm Labhart was killed at the factory field when a approach got too slow and started sinking...hit a bit short of the runway and pancaked the gear...nose dug in a bit, and enough of the rear structure came forward and killed him...after looking at the wreckage and seeing the crash site, I would bet anything a cub driver would have unbuckled and got out mad about the repairs he would have to make to get it flying again.
Now just as a word of caution to all out there...The danger of injury from rear impact in otherwise minor incidents isn't exclusive to pusher aircraft. Old school homebuilt legend Ken Brock was killed when his Thorp T18 run off a runway when he had a tailwheel linkage break. Supposedly he tried to keep it straight with differential braking but lost it at the end. He was killed by a small plastic box that rode on a baggage shelf behind the seats...It shot forward and hit him at the base of his neck. His wife was sitting next to him and didn't have a scratch. Everyone take a minute before your next flight and look in your cockpit...is everything as secure as it can be?
S12 flyer...If you are comfortable bouncing into the rough stuff in your S12 than awesome...like I said at first, everyone buys their own tickets and takes their own chances. Since this is "BACKCOUNTRY pilots" and the initial question was a fellow asking about modding a Titan...I was stating why I wouldn't recommend using a Titan in the "bush"...Not that it wouldn't be a great plane or great performer...because your typical bush strip mishap might be a lot worse than typical bush plane damage

I just point that out as a mental exercise...can't argue with NTSB statistics...(interesting thing about those...Have never seen a online NTSB narrative describe the structural failure mode of a crashed aircraft...at least not the synopsis version must people get on the web. "The structure of subject aircraft suffered local crippling of vertical bulkhead at station 1345...causing forward shift of overhead structure...etc."
I poly brush a patch on but don't bother to take it through the whole process all the way to finish paint, it just seems like a losing battle plus who cares down there. If someone tells you "oh yeah I do a lot of off airport and gravel bars" etc., take a peek at the belly of the plane, and you can gauge the frequency they do it.
