The 162's most dangerous aspects were the lack of proper glues to hold the aircraft together, and only a single, unreliable jet engine. It was only unreliable due to metal qualities and poor workers on the lines building these turbo-jets. Also the aircraft suffered from severe snaking (weaving) at high speeds making it an unstable firing platform, and the original, armed with only two 20mm cannon (the original idea was two mk-108, but the airframe couldnt handle it) it didnt have much firepower or ammunition to speak of. The snaking was temporarily reduced with down-turned wingtips and the nose was to be strengthened to carry the mk-108.
the mk-108 would make it less effective as a fighter though, with about 60rnds per gun and a low muzzle velocity, and only two guns (unlike four on the -262) and more of an interceptor instead of dogfighter/groundattack. Its limited range would prohibit long high level intercept missions. With the two 20mm cannon it would be effective against fighetrs and fighter/bombers, or anything at medium altitude or lower, but i certainly would not want to fly one at 20,000ft, with 30minutes of fuel and 120rounds of ammunition. Also with the engine on the dorsal part of the plane, rear view was almost non-existant (at 500mph its not too much an issue considering not much could catch it) and bailing out would have been a bitch, and i wouldnt want to trust the ejection seats, or glues.
If made out of light alloys, with more reliable engines, it would have been superb. But made out of alot of wood, with improper glues, engine quality and pilots, it was a death trap. Granted ORIGINAL pilots were experienced, but it was, as was stated, to be shifted to glider trained youth (hence the name, PEOPLES FIGHTER/volksjager).
