Crashing a plane is not an option, it just simply happens, sometimes we end up thinking for a long time how did it happen was it my fault or technical fault?

Well, many times its considered pilot's mistake. I saw senior and very carefuly flyer & I would consider him expert crashed his yak54 brand new at the field, elevator didnt respond, at particular area signals didnt work caused that huge gasser crashed. I had P51 Mustang PTS, crashed due to receiver failure, IF of receiver burned and it was JR's R700 slimline. I had a nose dive crash of my 40 size trainer with ASP .46 engine, luckily engine was safe nothing happened. I was flying my trainer quite well, suddenly all controls lost, plane didnt respond and took a nose dive then stopped on the ground, but anyway, plane crash can happen anytime anywhere nobody knows, as far as practice is concerned, yes it's a great thing, I have controlled my plane in such faster winds even 20mph. Enya's 4 Stroke engines have valves at the rear not at the front like all other manufacturers.
