P-30 Competition and Sport Model

The Monarch is a turnkey kit ready for quick assembly and great flight performance

The Monarch represents the latest in our line of kits and a new standard for P-30 construction. 

The Monarch is a robust model that builds easily with flight performance on par with its stable mate Boomer.  Features that allow this are the three panel wing, flat bottom AND unique flat top airfoil for both the wing and horizontal stabilizer.  No other P-30 on the market offers the unique truss rib structure that provides significant improvement for structural stiffness and resistance to twist. 

And thats not all!  The kit you order includes all hardware to build and fly without any additional items to purchase. 

The Button Classic viscous timer and Gizmogeezer Precision Free Wheeler propeller assembly are included as standard equipment in each kit along with all the necessary items to install a wing and stabilizer pop-up Dethermalizer system. 

Treat yourself to a Monarch kit today and enjoy one of the best flying P-30 models around.
