I too follow the FX3 accidents with great interest. It has a very high accident rate. Loss of control on the ground accounts for at least 50% of those. Surely the airplane cannot be blamed, although perhaps it possesses some characteristics that make it more difficult to control than other cubs (forward CG, relatively heavy weights on legacy gear, more HP/torque/left turning tendency). Obviously you can't really blame the airplane for this accident with the exhaust problem. I am glad I ordered earlier this year, as the prices for everything CC sells have gone up 10% over the summer.
I have 11,000 hours of flight time, most of which is irrelevant to flying a cub, and am not going to be able to get insurance in my FX3 until I obtain 50 hours in type most likely. I'm not complaining, it's just the facts. I only have 20 hours tailwheel and about 10 in PA-18's though. Even once I get 50 hours in fX3's I expect to be paying $10k/year. That's OK, I'll give myself a 5 knot crosswind/15 knot total wind limit, stay off the pavement for landings for awhile and just carry liability until I hit 50. If I wreck the airplane even after taking the tac-aero course and putting hard wind limits on myself, I deserve what I get. From talking to my insurance co. time in type is king, generic tailwheel time helps a little but until you get 50 hours in type they probably aren't going to write a policy for an experimental taildragger (at least my present company won't). No, they won't count PA-18 as time in type for a carbon cub.
People up here are charging $250-$400 to rent PA-18's plus an extra $75-$200/hr for instructors. Tac-Aero does training in actual FX-3's for almost same price, problem is you have to go there. You can rent an R44 with an instructor for about the same as some outfits charge for cub training around here. I'm told that some of these PA-18 training outfits are self-insuring now.
Anyway, just glad to have some FX3 discussions even if it's not all rainbows, sunshine, and unicorns. I take a fair amount of crap from people up here if they find out I ordered one saying it's not going to hold up. I didn't tell anyone except the guys I'm partnering in my Cessna with since I'm trying to sell my share of that one, but pilots are super good at gossiping.
