Eurofighter RC Jet SHOWS OFF in Turbulent Crosswinds! ✈️ EDF 90mm
31Watch the Freewing Eurofighter RC jet come back from the dead! The jet was repaired and flew successfully after the terrible crash shown in the previous video! :D
This jet shine as one of the BEST Freewing Jets! This 90mm EDF RC plane is one of the coolest foam jets in the market. She just flies so damn great and precise, even in turbulent crosswind conditions! Plus, it has a lot of power in the 8S configuration to allow proper fun at both fast and slow speeds. Watch it drift ass in the loaded rolls all around the place... and that's with all the ordnance loaded up... what a sight, what a thrill! Not to mention this is likely their easiest jet to land! If you don't have one in your collection, you are missing out big time!
These flights were also particularly exciting because we had truly gorgeous clouds as background, which make the videos a lot more interesting!! And of course, I am also using a gyro but that's besides the point. Other jets do NOT fare this well, even with stabilization helping out. ;)
The Freewing Eurofighter flies a lot more scale-like than most other rc jets in the same category do, mostly due to its canarded-delta design and unique aerodynamics. Also, this new Eurofighter offering by Freewing features wingtip twist, which very likely helps in that regard. The flight dynamics of the model make it look more like a full scale size jet than usual if you know how to pull the moves correctly with a trick or two... the jet just cuts through the air at a large angle of attack, drifting ass gracefully without wing rocking, stalling or snapping, even when excess sideslip develops. That's a feature that most deltas share, but that the Eurofighter reigns supreme at!
This jet doesn't feature the crazy maneuverability of its former versions which also featured thrust vectoring nozzles and were lighter, but it has a greater top speed and retains energy better, thanks to the newer, sleeker airframe design and larger, more true-to-scale wing planform. Wingtip twist also seems to have improved high alpha performance and stability, as expected (less wing rocking), though obviously the jet loses control sooner, due to the lack of TV nozzles.
Testing the airbrake, it doesn't seem to cause any undesired tendencies. Also, the mock drop tanks increase drag but they help the jet with high alpha as they shift the CG further aft, the CP slightly forward, and add some lift and lateral stability of their own!
Flights 36th to 40th on 'Lara'.

A note on CG: at 30mm (roughly) behind factory marks under the wings, the model is still noticeably nose heavy. Not too bad, decent enough for most users but definitely not ideal for those searching for the optimal aerobatic performance. One way or another, it's a shame that model aircraft manufacturers suggest such ridiculously over-exaggerated CG settings. There's no way a jet like this will fly any good with CG where they tell you to. At 25-30mm behind the marks, the jet is perfectly stable, with room to shift further aft. Actually, 25-30mm behind the marks is probably a much better spot for a maiden flight. Even then, sadly, the jet still required elevon pitch up trim. As of this moment, my canard offset is about 2mm LE down from the suggested fuselage marks. Will probably increase it further (pitch down) once I move the CG further back.
SETTINGS:
Long story short: Full mechanical throws with factory linkage setup (although I moved the linkages one hole further out on the canard servo atms to increase canard throws) and very large expo values all around, in the 70% range.
Mechanical offsets/trim:
Elevons: 2-3mm trailing edge up
Canards: 2mm pitch down (LE, root)
Rudder: Centered
Physical throws: YES.
