Overview

The Extra 330SX is the latest variant of the Extra Aerobatic Aircraft family, each version has different characteristics and they're always developed to be better. The SX is more precise, more floaty and much more agile than it's predecessor that Extra 330SC. The performance of Pilot RC's 90in (70cc) Extra 330SX feels more like that of a 120cc airframe, so if your looking for a big airframe feel in a 70cc then look no further than the Pilot-RC Extra 330SX.

This new design, combined with all of Pilot-RC's latest build innovations and methods provide a high quality kit that can be built within minutes upon arrival at the flying field and relied upon for strength, agility and all round fun.
