I have the following planes and engines and would like to know how you would match them and your opinions on my suggestions.

CGTiger 40 (61" Wingspan)
Midwest Aerostar 40 Trainer (62" Wingspan)
Modeltech Magic Extra 300L (51" Wingspan)

OS40 LA 2 stroke
Super Tigre S40 (Italian) 2 stroke
Magnum XLS46 2 stroke
Saito 40 4 stroke
OSFS52 Surpass 4 Stroke

I am thinking the following:
Aerostar 40OS40 LA
Modeltech MagicMagnum XLS 46 or Saito 40
Tiger 40Super Tigre S40 or OSFS52 Surpass

My main debate is the 4 strokes.....would they be enough for these airframes.

Thanks
