With a Big Stik, you can fly slow & easy or set the sky on fire – & do both after just 12-15 hours of assembly. Both versions are 90% pre-built, with interlocking wood airframes that run arrow-straight & super-strong. The finish offers the glossy good looks & puncture-resistant strength of Mono Kote with the traditional ' Maltese Cross' markings. But the biggest Big Stik benefit is their performance! A high wing design & massive wing areas make them stable & easy to control – even at low speeds. & with their dual aileron servos, huge control surfaces & virtually symmetrical airfoils, you can reach the outer limits of 3D manoeuvres. Requires 4-5 channel R/C with 5 servos.
