Ok, well with the Saito price increase since yesterday I'm looking for an engine again for this plane. Has anyone actually flown it with a .91 four stroke?(was looking at the Saito 100, but not at the new price of $329). I'm debating between a Mag 1.20, Mag .91 or a Thunder Tiger .91. Anyone used any of these engines on this bird/birds this size? I'd be interested to know the power difference between the TT and the Mag .91....if anyone knows.
