I don't have any Freewing birds in my hangar yet. But, you might have just nudged me to start window shopping 😊 Currently waiting for the visa card to stop actively smoking before I can work that sob hard again! Thanks for the deep dive on this one, Jon. And I'll keep that "It's not a monster truck" advice in mind, next time I slam my Maule onto its new monster truck tires 😅 👍
A monster truck Maule sounds like a bunch of fun. We're still waiting on our inflatable 1300mm Super Cub wheels to arrive so we can toss them on our Maule. Model airplanes have to make sacrifices to be lightweight (relatively) and still flyable within a reasonable envelope. Landing gear mounts are usually one of those sacrifices. In Eurofighter's case, that's thankfully not the issue, but you can crack the plane in half exactly where those two photos show if you slam it in consistently. It's just not designed for that kind of flying - you actually have to fly it down to the ground to avoid that.
@@TwoBrosRC Just FYI- Those PA18 1.3m wheels require some minor grinding down to fit the shorter Maule hubs. But, OMG is it worth the time and effort!! 👍🏼
Just came across your videos of euro fighter from last year today and subscribed. Great video. You reference the control surfaces rates being tied to speed. I assume you mean throttle position? You’re the first UA-camr I have seen sharing som much on mixing, rates, etc… Much appreciated! I have done several complex mixed planes that leave most R/C’ers scratching their heads. But, I’m always learning. Euro fighter being purchased :-)
Thanks Anthony! The behavior Jon was talking about is in reference to the gyro, not the surfaces. In full scale fighter jets, stabilization and throw are both controlled by the flight computer. On model aircraft, the best we can do is limit the stabilization by approximating airspeed thresholds using the throttle position as a crude guide. We use full throws, but the gyro is governed by throttle position and the position of the sliders on the back of our IX20.
@@TwoBrosRC I figured that's what he's talking about. He referred to it with speeds. I'm a full scale pilot too, understand what the full scale planes are doing. I ran into issues with throttle curve mixes on a couple of planes where I chopped the throttle and how too much deflection but still going fast or was needing to punch it while too low and didn't have the throw I need. Would be nice if we could tie this to true airspeed at some point. Use IAS like UASs do from a tiny pitot tube and feed that to a control thow mix. My bet is you guys will be the first to do it from what I have seen.
@AnthonyPuca I tried to use Frskys pitot sensor for this exact purpose, but the telemetry had some delay. Maybe it could have been fixed, but sometimes it lost the sensor as well so I ended up with a gain mix that was tied to the throttle. Not only that, but with slow up and slow down added to the mix to get a closer correlation with actual speed. I have some flights with the Eurofighter on an 8 ch receiver, but now there is a Frsky SR10+ mounted with dual stabilizers - the second one controlling the canards with separate gains and throws. Waiting for the snow ❄️ to go away to test it. Great video by the way!
Fantastic vid. Im now for surw buying that bird. And for surenit also wont be setup like yours that your setups are over my head. Lol.. Besides i just have a NX8.
I can say from having a v1 that it's such a good flying jet, i put countless flights on it using only 5 channels, zero expo, standard elevon mixing and no gyro, so nothing else is really needed but more just a luxury on this bird. I'm saying this for the people like me who just like to simplify it, put a fresh battery in it and go rip it, she'll do just fine...until it doesn't (servo failure😭).
Yeah man, however you want to fly is all that should matter. We prefer to emulate how full scale jets fly. Not everyone does, though. And it does require a bit more stick skill to fly something as tail heavy as our jets, even with augmented stability. You still have to know how to operate within the jet's flight envelope. Departing from it can lead to unrecoverable crashes. But it's so much more fun to have a jet that does exactly what you tell it to do!
Great video buying one typhoon in the next two weeks and will look at doing the same mods you have done yourself.. Are you able to upload your radio set up for this jet.. would be great if you can 😊
Awesome video! I picked up the Gripen a couple months ago based on your reviews. I finally got to do the maiden flight and had a blast flying it. If you're telling me this Eurofighter is even more fun.....time to put another order in at Motion RC lol.
Sorry to bother you John, but could I get enough functionality out of a NX8 to make this jet really perform. I'm sure you do if you change the landing gear over to the radio but what else?
It's no bother, we try to answer everyone. The NX8 is more than enough to fly this jet in stock form. It'll just roll weird because the canards are mixed into aileron movement by default, when they should not be. So you'd need to split the channels for them to be pitch-only as they should be.
Very unfortunate that FW haven't done a V3,5 of this jet otherwise I would buy it instantly. I am just not ok with paying over 700 euros for a jet where i have to so heavily modify the battery bay to get neutral gyro stability and also I definitely would not invest the effort to mix the gear myself. A real pity bc the jet looks dope especially with that afterbourner and lighting system.
That's basically how all FW jets are. If you want neutral to tail heavy balance like we do, you gotta do some work to make it happen. J-10, Eurofighter, F-22, they're all like this.
@@TwoBrosRC Not necessarily, I own the mirage 80mm and the F16 70mm V3, I can achieve a very nice CG with both. Also the new F16 90m V2 seems to have a very generous battery bay on first glance. Particularly the super slow landing gear also seems to be Eurofighter exclusive...
Mirage and the F-16 are sort of an outlier. The bigger the planes get, the harder it is to find a CG that allows you to do the stuff we're doing. Hence why the 90mm jets tend to be the most frustrating in this aspect.
Hey buddy, really dumb question. When you are running your As3x gains, is that assisting for just winds, or is it with stability if you lose orientation?
@@TwoBrosRC cause I have a hard time saving money and I’ll always end up selling something to get something different. And I will admit, I was almost to a point of selling my tomcat cause it has some problems.

Nonsense. Airflow doesn't flow aligned with the wing where the canards are placed. The very presence of a cambered wing modifies the entire fluid field around it, both downstream and upstream. If you set the canards flat, they'll be causing a permanent pitch up, which honestly, pretty much sucks because combined with a nose heavy CG it kills all the agility and maneuverability that make such an airplane a real beast. I personally wouldn't set them with such a big offset as Jon shows, but his idea is perfectly sound. Mine are also trimmed slightly 'pitch-down', which doesn't actually cause a pitch down per se, but more of a 'less-pitch up' contribution. It's like owning a ferrari and trying to drive it around with the parking brake on. Sure, you may overpower it with sheer force and still be able to get from point A to B, but it sure is a damn waste. 😂😂😂 As for the ordnance, again, more nonsense.
