If you use a .46-size engine, you'll have to put the battery under the fuel tank. The plane weighs 6 pounds, so for better flight performance, I recommend the larger engine especially if you're good with throttle management. If your construction time is limited and you're searching for an ARF biplane that has an easy wing-setup method, the Global Ultimate ARF is for you. Its prebuilt wings, interplane struts and preassembled and attached cabane struts mean that the tedious task of wing alignment has been completed for you at the factory. With the great covering job on the airframe, the painted cowl and the aforementioned features, you would be hard pressed to find a better prebuilt and covered model and one that goes together as quickly.
Time is now on our side.
Addresses are listed alphabetically in the Index of Manufacturers in the magazine. Even on our rough grass field, the Ultimate was able to taxi without any problems. Owing to the coarseness of the surface and the lower wing's proximity to the ground, the Ultimate took 60 to 70 feet to become airborne. I applied throttle gradually and needed very little right rudder to keep the model tracking straight. It stalls straight ahead, but it takes a bit of altitude to recover, so don't stall it close to the ground.
