EJ22 EJ22T EJ25 EJ25T ... designing a helicopter that needs 350hp.. not not a roo i know getting 350 out of a EJ22 might be a little hard...

Andyjo Posted February 19, 2007 Author Share Posted February 19, 2007 sweet, i like that weight better than the other i found. hmm.. with 4 of those puppies running maybe we can utilize the exhaust to heat a ram jet... and maybe strap some hybrid rockets on to the bottom for some sub-orbital fun!! imagine that... you hike to 30,000ft, then you get picked up by a copter and rocket to sub orbit... mauhaahha!!! or... not...
