Description
The Max Thrust Double Trouble Balsa Pro-Built delivers pure aerobatic excitement in a compact, beautifully finished 44-inch biplane. Sharing the same locked-in flying characteristics as the popular Ruckus, but in a smaller, more agile package, the Double Trouble is built for pilots who like to fly hard and fly often.
Factory built, covered and finished, this Pro-Built version removes the build time while retaining the strength and longevity of traditional balsa and ply construction. The Ultimate-inspired layout, combined with classic open-cockpit styling cues from aircraft such as the Pitts and Stampe, gives the model a timeless look and superb presence in the air.
Equally happy on glow or electric power, the Double Trouble offers excellent slow-speed manners, outstanding ground handling and the durability needed for everyday UK club flying. Compact enough to fit easily in a small car, yet capable of full-house aerobatics, it’s a no-nonsense, all-season biplane that rewards confident flying with huge smiles.
