My Vertigo first flew with a muffled Magnum .61XLS (13,100 rpm on an 11/7 APC). This is more tha adequate power for this aircraft, as previously stated the Vertigo is a faster design than the Phoenix. You will not have "unlimited" vertical performance, but then that is unnecessary for Novice class flying.

The Vertigo now sports a piped OS .65AX (Approximately equal to the Rossi) and not only is it much faster, but now has the vertical performance for Masters.
