Learn to Land RC EDF Jets

Landing EDFs - once they're properly set up - is a real joy and nothing to be afraid of. Plan ahead of what your aircraft is doing, use throttle on landing, and use an appropriate level of flaps for the type of aircraft you're flying and you'll find that it will float down to a gentle landing if you remember to maintain a shallow glideslope and flare before touchdown.

[@garyvale8347]

as a fairly new pilot and someone interested in EDF's...these types of flight videos, along with the detailed narrative are super helpful...thanks much for the very informative video!!! ...

[@TwoBrosRC]

Thank you Gary! I'm happy you enjoyed.

[@carbonEYE007]

Go for it! the first time you raise up into freedom off the runway it will all be worth it

[@seany11244]

Guys at the field ask me how I grease my landings given any plane and any circumstance. As a full scale pilot, I give them a bit of ground schooling. I call it the 4 A's. This is what you need to be continually processing on your approach and in this order: 1. Airspeed, 2. Ang of Attack or Alpha, 3. Altitude, and 4..Alignment (with the centerline). Essentially I'm training them to think like an autopilot. This might a bit much for the beginner, but if you follow this order, you'll will have success every time.

[@tennesseenrelicslive]

Flairing right before touchdown and right amount of low throttle is key. Great video Jon!

[@TwoBrosRC]

Not just that, but having the right setup so you don't porpoise once you flare!

[@keitha.9788]

In flying real aircraft (the one's that you actually ride in), low performance aircraft one typically will stall the aircraft a few inches above the ground during landing, keeping constant back pressure on the stick. High performance aircraft are landed differently - You actually fly the aircraft on to the ground. Consequently, the landing is made higher speed with a longer roll-out.. Excellent Video!!!!!!!

[@txkflier]

I have the 70mm E-flite Viper and it will tip stall in a heartbeat. I haven't flown the 90mm version. On my EDF's, I put the transmitter's flight modes on the flap switch and enable F-Mode Trim. This gives me separate aileron and elevator trims for each position of the flaps. I'll shoot approaches with the flaps in takeoff and landing position with the power off and adjust the elevator trim so that the plane glides without getting too slow or descending too quickly. When I'm on final, I don't really think about airspeed. I use the elevator to control the angle of attack and the throttle to control the descent rate.

[@fdm225]

i appreciate that you are calling out the throttle position as you are coming in. I find that a lot of KZbin videos on this subject neglect to discuss where the the throttle is set at different stages of the landing. I fly mostly 80/90mm EDF jets at a space constrained flying field, it would be interesting to see you make a video like this for a filed that requires you to come in around (or over) trees to land (would help me greatly). Great series of videos, thanks!

[@helicopter234]

When there's little to no wind its really easy, it gets really challenging when there's a lot of gusty wind, especially when you don't have a gyro to help. I've found that going in with only half flaps and a bit faster is safer on windy days than going with full flaps and slower, the plane gets thrown around much harder with full flaps!

[@TwoBrosRC]

Thank you! There's a bit of down elevator mixed in - the specific values can be found in the Viper 90 setup I believe: kzbin.info/www/bejne/q4aye5uCp7icmNk Flap timer is about 3 or 4 seconds - at 150% rates 4 seconds is needed to produce a 2 second deployment speed.

[@bestoh0428]

This is a very helpful tutorial. Thank you. BTW, I have a question about how you apply the elevator. I have a tendency of applying up elevator from the approach to the end. Are you applying up elevator only while you are flaring?

I hold very light amounts of elevator control while descending. Most of the pitch authority is coming from throttle control.

[@TwoBrosRC]

I did! I'm running tinyurl.com/B13DLM servos on the ailerons and elevators currently for additional torque (3.8kg at 6v) to have more precision and more of a linear response with less blowback.

[@speedyswede5585]

@@TwoBrosRC Thanks for the response. So do you treat all e-Flite servos as "barely adequate" and upgrade or are there some factory applications that serve the purpose. I too have automatically replaced servos in higher performance models of other brands.

[@TwoBrosRC]

Wrong link above - it's tinyurl.com/B13DLM - sorry about that. With regard to servo upgrades, it depends. Sometimes I do feel that the servos included aren't precise enough for my tastes or don't have enough torque. This model flies perfectly fine without the servos I'm using, but I wanted the additional torque and precision they offer.

Yes, that's correct - full movement with roughly 70% expo on all surfaces for this jet.

[@artconn2538]

Hi Jon..... I realize this clip is quite old however I still found the content to be both very informative and relevant. My question to you is: Would you consider the Habu or Banshee good planes to utilize the skills you demonstrated on this video for a beginner? I've been flying my Aeroscout for about 2 months and I'm up to 400 touch and go's out of a goal of 1000 I set for myself. :) Also, what would you consider to be the superior beginner plane, the Habu or the Banshee? I'm hoping to get a Viper 90 mm in about a year or two.

[@TwoBrosRC]

Habu floats forever. Banshee probably won't. You'll be better off practicing on a Banshee if you're trying to build skills. The Habu is better for relaxed stress-free flying because it's almost unstallable.

[@LoveRC]

Uhg so I have to remove the receiver and put in an 8 channel to get it to land good? Great video!!!!

[@TwoBrosRC]

Well, it's either that or you make really long glideslopes which come with an inherent risk of misjudging airspeed and stalling a wing. I've never seen a Viper jet stall straight forward - it always drops in a sharp bank to the right or left. With my alpha crow mixing, you can actually get it to perform the 3D "elevator" move where it just stalls straight down without dropping a wing - further proving that crow is invaluable on this model.

[@LoveRC]

@@TwoBrosRC So you use your crow on banking to final? I thought you didn't turn it on until you were on final?? I'll watch your video some more. Anyway I have the 8360T. I was going to use it on a different jet but might just use it on this one. You have two files. 000_ViperJet_90mm.spm which is the spektrum setup file. What is the 000_ViperJet_90mm.ispm file?

[@TwoBrosRC]

It's on when the wings are leveled. Don't look at it like braking - look at it like you're introducing a lower stall speed at higher angles of attack. The iSPM file is for IX radios. The SPM should work, if not, the setup basics are in my video called Viper 90mm Maximum Performance Setup.

[@LoveRC]

[@stevecompton9644]

When in the approach sequence do you deploy the crow setting and when after you have gotten airborn again to you go back to normal ailerons? Also, if you have an edf without flaps would you suggest still setting up crow or program flaperons? Thanks!

[@TwoBrosRC]

Crow is automatic on full flaps in my setup. You can take off with crow but it's best practice to go back to takeoff flaps or no flaps before rotating. Without flaps, it would depend on the model.

[@colinggold]

I use flaperons with my jets without flaps but only use half falls otherwise I loose aileron authority

[@alexgonzales1855]

When landing at final. Do you move throttle more ? Or pitch? I have a habu 50mm and a tend to bounce.

[@TwoBrosRC]

If you're bouncing, it's because you're dropping the model too hard. You need to flare before landing.

Yeah, you need a decent amount of elevator correction when crow is deployed. The upward aileron reflex acts like upward elevator which needs to be neutralized in the mix. Check tinyurl.com/SynRCSetupFiles for the Viper setup file I'm flying with - which includes the crow mixing for you.

@@TwoBrosRC thank you for the help. I use a flight controller and edgeTX with my viper, not sure if the config file is compatible. With this being said I would need a percentage of down elevator?

@@sodjazero I use the innermost hole on the elevator, longer servo arms with more precise servos, and 150% rates. My values likely won't translate to your setup, but a good ballpark figure to start with is 8 to 16% down elevator.

Okay now everyone turn your gyros completely off….. and let the good times roll!

[@TwoBrosRC]

I mean, why though? I can land and fly with or without a gyro - I just prefer having my models stabilized.

[@Mode1RC]

"Severe tip stall characteristics?!" I could not disagree more. This model has the most benign handling of any EDF I've ever flown. Slow speed handling is fantastic, super forgiving.

[@TwoBrosRC]

Try flying it at low speeds and you'll see what I'm talking about. Viper style aircraft have very bad tip stall characteristics caused by the winglets generating negative washout and, generally, a highly loaded wing. Neither of which is conducive to a jet that handles well at low speeds. There's plenty of video evidence of how these airframes stall - all of which can be seriously alleviated by using crow to introduce washout during landing with flaps deployed. You can look through my video history to see more about its stall characteristics, especially the high alpha attempt which led to a crash (dropped a wing in a tip stall) and the high alpha sport jet tutorial I created which has a segment demonstrating just how nasty its stall can be, including several successive tip stalls in a row.

[@Mode1RC]

@@TwoBrosRC I've flown low figure 8s slower than yours lands, because I don't use crow. Crow reduces available lift and increases the stall speed. And at 8:30 where it 'tip stalls', the model is almost knife edge. Of course it's going to stall/drop, because the wing isn't doing any work. Video 'evidence' is strongly influenced by pilot skill. Which is difficult to evaluate on a small screen. I've seen in person some good pilots fly this model low and slow with no issues, and had none with mine.

[@TwoBrosRC]

While crow does reduce some lift at the wingtips - it enhances lift distribution because it forces a stall to begin at the wing root rather than at the wingtip. And yes, it does increase the wing's stall speed. So no, I doubt you're flying figure 8 patterns slower than I'm landing because this model stalls around 25 MPH with crow and around 29 MPH without it. If you're going slower than that, you're flying into a headwind. I'm usually landing this model within 5 MPH of its stall speed. At 8:30 you're seeing it drop the wing even further because the lift distribution is entirely unequal and the airspeed necessary to maintain flight at that point wasn't kept up. It's an extreme example - but a better one would be looking into the alpha tutorial I mentioned where I covered this extensively: kzbin.info/www/bejne/eHK1nGBsh9KWppY This model (and any similar model with a high wind loading) will suffer from tip stalls and accelerated stalls. It's a consequence of the design. Crow eliminates that. I'm not against admitting that I'm wrong when I'm demonstrably proven wrong - so if you've got video of you flying in figure 8 patterns and going slow - which is apparently not an objective term whatsoever - I'd love to see it. Because my experience in hundreds of flights on the Viper is that it does not handle slow speeds well and is susceptible to an immediate and violent stall, such as the one that IJGH experienced: kzbin.info/www/bejne/m3aaoK2hpdygaa8

[@Mode1RC]

@@TwoBrosRC I think we can agree to disagree, until we have more subjective evidence :-) The fact that you say tipstall so much is a negative for me, as it is absolutely one of the most overused and misunderstood terms in model aviation. And you admit that crow increases stall speed, yet also that you land slower with it? Doesn't make any sense.

[@TwoBrosRC]

I have many videos demonstrating the Viper and its capabilities. I don't see anything on your channel. It's hard to "agree to disagree" with someone who doesn't have any evidence while I've got a ton of it. If you want to provide evidence for what you've written, please do so - otherwise I can't take what you've said seriously because there's nothing backing your claims. With regard to stall speed, when I said "increase" I think any reasonable person could deduce that I meant "reduces stall speed" when I mentioned that the stall speed with crow is 25 MPH. I definitely make mistakes when I type and that was one of them - but it's not worth being pedantic about. With regard to tip stall being overused, I'll agree there, but that's not the case here. The wingtip stalling causes the jet to drop a wing in an asymmetrical stall. At low level, it's completely unrecoverable and leads to potentially serious damage to the airframe. If a wing didn't drop, I wouldn't call it a tip stall.
