When you've mastered that 'trainer' you'll need to move on, so look no further than the Sonic Low wing! Not only is the Sonic an ideal second model, it has enough new challenges in terms of flight performance to suit sports modellers as well. It has sturdy all balsa/plywood construction. You can fly this plane after 1-2 hours of installation. All the hardware are included (servo wire, fuel tank, wheel/landing gear, etc). You only need to separately purchase the nitro engine and radio system.
