Description
Introducing the 39" Crack Yak-55, the larger sibling of our iconic model. With a new wing core, tapered tips, and enhanced features like the T-Canalizer and optimized SFG placement, it excels in stronger winds and KE stability. Based on Chris Jewett's 32" version, this larger model offers even more thrilling flights.
Upgrades include adjustable push rod assemblies, EPP bracing, and dual aileron servos for easy assembly and a sleek look. The expanded flight envelope provides unmatched control and a higher roll rate, perfect for advanced pilots or those seeking a balsa 3D alternative. Spinner not included.

YAK review
I find that the motor mount wood seperates after a few flights, The landing gear mounting is not designed for grass fields, one must put a plate on the top # using long #2 machine screw fasted the landing gear to that. Other wise I am delighted.
