The Flex Innovations QQ Extra 300G2 is the second generation of the very popular and successful QQ Extra 300. Improvements from the Flex Innovations' Design Team and valuable feedback from customers around the world have been incorporated to evolve the QQ Extra 300G2 to the next level!

The Potenza 10 BL motor (1400kv) paired with a larger 50A ESC delivers more power that translates into more punch out from a hover and greater top speed. The Potenza DS15 digital servos offer better precision and better reliability. Vibrant new color schemes bring outstanding visibility and modern flavor.

A perfectly balanced airframe and super light design have been combined with today’s most Advanced Flight Control System, the Aura 8. Using the latest Aura 8 firmware, the QQ Extra 300G2 gives an unmatched flying experience. Pilots will feel smooth, predictable and precise aircraft control without any bounce back or interference to pilot inputs. The aircraft will fly as if it were much larger with turbulent air being less noticeable, rotations stopping more precisely, and smoother landings! 

The meticulous Quique Somenzini design and manufacturing of the QQ Extra 300G2 gives you light and stiff at the same time due to the hollow interior design with strength from carbon fiber in key locations. Because it is EPO foam, it remains tough and repairable.

The QQ Extra 300G2 is all around the perfect airplane for those wanting to do sport flying or 3D aerobatics with maximum fun and minimal hassle! It’s the Go-To airplane!

Flex Innovations QQ Extra 300G2 Super PNP Electric Airplane (Green) (1215mm)
I have been a long time Flex customer. Owned both Mamba 10s, QQ Extras G2 and V1. Love the way they fly when manufacturing mistakes are found and fixed.

I have purchased two planes from Flex Innovations recently with QC problems. Quality control has been non-existent on these planes - poorly glued control surfaces and bad hardware - Broken plastic clevis clip on elevator caused a Mambo 10 to self destruct 1/2 way into maiden. When this Extra 300 arrived last week, I carefully went over the hardware and found three surfaces with only one hinge glued. At least 6 hinges had not a trace of glue - 2 on ailerons, 2 on rudder and 2 on elevator. One clevis had no center pin, and one pin broke upon closure. BE SURE TO REPLACE THE PLASTIC LINKS!!!!!

I have been flying and building for 35 years, draw your own conclusions, however, I believe an newer pilot would not be able to make this plane fly safely as delivered.

A really fun and lively plane to fly. I’m an advanced beginner (or something like that) and I’ve really enjoyed flying and learning aerobatics with it. It is amazingly smooth, responsive, powerful, and stable all in one. I’ve flown it in pretty strong winds and it acts as if there is no wind at all. I can take my hands of the sticks and it is just rock solid. I would highly recommend this plane. I don’t know enough about 3D flying to know if this is a super 3D plane, but it seems to be quite capable. I’ve been getting 5+ minutes of flight time on a 3S 2200mA 60C Lipo. Landings have been pretty much soft harrier drops. Taxiing on well cut grass has not been a problem. Take-offs are nearly vertical. I purchased mine through FliteTest and it arrived quickly, and was well packaged.

I took a star off for minor fit and finish issues. I have planes that cost less that have significantly better fit and finish. The foam in the nose is soft and like mush, the battery tray/strapping is underwhelming and I beefed it up, linkages are not high-quality, and I added a tab to the battery hatch to get it opened without digging into the foam. I would like the winglets to be removable so I could store the plane in the original packaging. Those are all minor fit and finish issues, though it seems it would not have cost much to improve them all.

But… the plane flies great, and is a lot of fun. Go get yourself one.
