I recently purchased the ModelTech Magic. The following design and kitting mistakes were noted:
Rudder and Elevator pushrod connectors are the wrong size.
Fuel tank does not fit into fuselage properly. Mounts in at a rearward sloping angle of 15 degrees.
Landing gear is weak and breaks easily. Recommended mounting method of landing gear of 4 small screws is weak also. I modified the landing gear.
The worst item is that the fuselage is constructed in two pieces joined just behind the trailing edge of the wing. After about 30 flights this fuselage splice cracked and I was able to land it with considerable effort. I have written to ModelTech requesting a replacement airplane. If I get the new plane I will reconstruct the fuselage joint.

Other than that the airplane performs very well in the air. The airplane only costs $99. When I complained to the dealer about the defects he said that "What can you expect for $99"? I believe that we can expect at least the correct parts in a kit and can expect basic good construction.
