SKU: FPM4170

Everyone wants more power and more flight time for their 10-class aircraft, but performance enhancements have always been limited by the power system and the 3S (11.1V) Li-Po’s they typically use. Going back to the drawing board, the Flex Innovations Team started over with a new idea: to use a totally redesigned power system, with a small, lightweight and inexpensive 6S (22.2V) Li-Po to totally revolutionize the performance of 10-class aircraft. What does this mean for you? No more dreaming, you really do get it all! More Power. More Flight Time. And most importantly; More Fun!

Revolutionizing flying wing performance, the Piraña is an extraordinary aircraft that stands above the crowd! The Piraña not only shares some key aesthetics with LMP cars racing at Le Mans, it mirrors their performance too! The Piraña has big power and high-speed capabilities, while also maintaining extraordinary handling thanks to designer and F3A and 3D World Champion, Quique Somenzini. From the craziest of aerobatic maneuvers, to high speed and slow-speed flight, the Piraña bundles an incredibly wide flight envelope with performance and power in a convenient package. Whether you’re flying the Piraña under your FPV goggles, or by traditional means, it will be sure to put a smile on your face every time you fly it!


  • Wide flight envelope, from slow speed, to high speed and crazy aerobatic maneuvers, the Piraña can do it all!
  • New 6S (22.2V) Li-Po power system for more power and more flight time
  • FT Aura 5 Lite Advanced Flight Control System enhances the flight without ever feeling intrusive. (It’s more than a gyro!)
  • Designed by world renowned designer, Quique Somenzini
  • Launch Assist helps provide worry-free hand launches and helps you focus on the fun – flying!
  • Internally mounted LEDs are installed and illuminate the aircraft from the inside
  • Level Assist (6-Axis) can be configured without the use of a computer and adds great assistance for newer pilots. Level Assist limits bank and pitch angles so that the aircraft cannot be over controlled, as well as returns the aircraft to level flight when the controls are returned to neutral.
  • APC 6.5 x 6.5 propeller provides power, speed and throttle response
  • Removable fins and wings allow the Piraña to be easily disassembled into a compact package.
  • Airbrakes can be configured without the use of a computer and adds additional fun. No mixing in
  • Potenza 20L 1200Kv motor is lightweight and optimized for 6S (22.2V) Li-Pos
  • FPV-ready nose is included with the Super PNP
  • (2) DS17 and (2) DS12 servos installed
  • Custom control horns for optimized throw and precision
  • Available in two high-visibility color variants

    I don’t know why I’m the first to write a review since this thing is awesome and the auto take off is the best feature in an electric plane thus far… I have not yet tried the rudder brake but that is next on my list…I love it in every way. Easy to see my orange one and it does move along very nice. Flex hit the mark on this one… I sold my v900 after flying this one. Not as fast, but more of a pleasure to fly and launch………launch assist beats out safe as3x in every way.

    I don’t know why I am only the second one to review this cool flyer. Launch assist is great — works 100%. Plane is plenty fast for me and the orange works well under our cloudy skies. Using the Spektrum Rx and Potenza batteries. Get one of these !! I may have some video shortly of a launch at my field shortly.

    Don’t know why I’m only the 3rd reviewer 🙂 Very fun plane. Follow the instructions closely. There is a learning curve with the Aura but, if I can handle it, virtually anyone can. I use a Spektrum DX8G2 TX and the Flex DSMX Diversity RX. Potenza 1500mHa 6s cells. Launch Assist and Air-Brakes work exceptionally well. And, that’s good cuz I need both. Customer Service is top notch imo. All that said I might not recommend the Pirana to a new pilot. It gets small and it gets small fast. The FT Aura 5 Lite flight control board is by far the best in its class. Rock solid. You need a little patience. Study the videos and documents and you’ll be satisfied. You should fly one too.

    I don’t know why I am only the 4th 🙂 Overall its a great little plane! Plug and play. The “launch assist” is amazing and rips across the sky. Full rates and its a blur and will do crazy spins and flips. Aura 5 is quite the little unit and I used the PC to review the settings. Air brakes, super cool. Overall love it! So why 4 stars? I think the lights on the bottom would be better pointed down vs up. Also clear could have been used around the LEDs so they were brighter at night. But its easy to add more LEDs. The Aura buttons (trim and bind) are located in a weird spot, you have to have tiny baby fingers if you are to press them especially at the same time. But the REAL 4 starts is the canopy. Its hinged from the back and I lost mine (at night flying) on the 5th flight doing crazy high speed 3D. Why they decided to open like a hood of a car is beyond me. ADD A PIN OR ANOTHER WAY TO HOLD THE CANOPY DOWN IN THE FRONT.

    I dumb thumbed the initial launch and damaged the fuselage beyond repair. I ordered a replacement part from the web site, which said they were “in stock”. When I opened the box, no fuselage was in it. They have no idea when replacement parts will be available.
    I cannot recommend any airplane that is not supported with parts. Especially frustrating that they had them listed in stock when they weren’t.

      Hi John,

      Thanks for your feedback! While we do try very hard to keep our website up to date, there can occasionally be errors. For your order, we shipped all items on the order except the fuselage since it was out of stock and backordered. We do our best to keep replacement parts in stock, but with today’s challenges in the supply chain, it can be quite hard to keep inventory in stock at all times. We did receive a new shipment of parts last week and Piraña fuselages were part of that shipment, so your fuselage should have been delivered to you, or be on its way to you.

    I purchased the Pirana locally and found the right wing half does not have the hole for the longer wing tube. The plane seems to be pretty good quality and easy to assemble, otherwise, but now I now have to wait…

  7. Chris Kaiser

    I purchased a second Pirana since my first one had no wing tube hole in the right wing. I setup the second one and it was ready to fly until I plugged in a battery and nothing worked. I tested the ESC and servos with another plane and they do not work. My brand new Futaba receiver also now does not work. I must not be meant to own Flex planes.

    I love this plane. I’m used to flying the Funjet and the V900, but when I started flying the Pirana, I hardly ever fly the others. The V900 is faster but not by much. It is not as much fun to fly. Launching the V900 is rough, even in Safe Mode. The Pirana’s launch assist is amazing. Works everytime. No stressful launches anymore. Love the air brakes, they work great. Super fun to fly. Thinking about buying another on in case they ever discontinue the Pirana.
