Compressed air blows, that's why. 34 whr/kg and a whr/L thingy that is so darned low the Devil has to look down at it. BUT, ignoring that completely, can you put an air tank at say 2000psi in your little plane, and use the air pressure to directly turn the prop in such a way as to mimic a 15hp two stroke? enough torque? thrust? Electric motors are very efficient but what about the efficiency of pneumatic motors? Can the hoses handle it? Would it weigh more than my ex-girlfriend? Just a "what if" question i put to myself last time i took a stroll through "wonderland". Would be fun to see if it can be done for a few short theoretical minutes.
