I have this plane. He powered MDS 148 and the power of this enough for unlimited vertical. Prop used: MA scimitar 19x8. But! Replace turtledeck & hatch to foam core balsa sheeted parts. Replace cowl to FG to reduce weight. Also replace u/carriage to CF. If possible replace wing tube to CF. Total weight of my plane - 11,5 lbs. All control surfaces enlarged. E.g. elevators - 60% of stab, rudder - 60% of fin.
