RE: engine recomendation please:
Super Tigre 45, Magnum 46, Magnum 52 two stroke, Magnum 70 4s engines. I have (2) of the Mag 46's and they run great. The 52 two stoke was a little bit more finicky at first but has gobs of power. I love my Magnum 4s engines. Super easy to tune and run smooth as can be.
If you want a cruiser, the Super Tigre 45 or Mag 46. Vertical climbs the Mag 52. All around flyer with good power, the Mag 70fs.
