Do you perhaps have a profile on RCG or similar?

Thanks for the feedback. The series was a lot of work to produce, so I appreciate your comment. I haven't made a behind the scenes video of the sensors and telemetry data yet, but I have considered making one. A few people have asked about it. It is a bit daunting at first. The sensors should be listed in the description. They are all FrSky. I get continuous voice callouts for airspeed during the landing phase (LDG Mode ON), altitude only when I drop the gear, and voltage alerts only when cautionary or critical. The remaining telemetry is logged along with the above and saved as a csv file. That is synced up with the video in Dashware, which is available for free on the web (last I checked). In Dashware you can use stock instruments or make your own. Once everything is setup you can save the instrument panel as a template for the specific plane that you collected telemetry from, so it's much easier the next time. That's it!

The gear is stock and there is an idle thrust set at about 15% with throttle stick all the way back. The key is landing on the mains, never nose first. To get the nose up the jet has to be slow enough to rotate without climbing, so controlling your speed is important. I would practice some stalls at altitude to get comfortable with the slow end of the flight envelope. The stock Avanti stalls at about 17 mph with a 6s 6200 mAh pack. Very slow! Just line up early and go easy on the stick to avoid stalling on final. You can find more tips at the end of Part 6 of my video series on landing an EDF jet. Just click on my avatar, go to my channel, and look for the playlist, By the Numbers.

@@rcnfo1197 Thank you!!! I've read somewhere the V2 nose landing gear helps a lot. And moving the CG back to 121mm too. I'll watch your videos.

@@ivanvela5441 You're welcome! The shorter V2 nose gear lowers the AOA and dumps lift on touchdown. So, yes, that helps prevent bouncing. But landing slower will do the same.

@@rcnfo1197 I think moving back the CG will help too. When I go slow enough to land without bouncing, the elevator stops helping to rotate and I finally end touching first with the nose gear instead of main. If I push the throttle a little more to be able to rotate and avoid nose gear to touch first, the bird doesn't want to land and turns into positive ascent rate. My actual CG is per manual 105-110mm. Thanks for your help.

@@ivanvela5441 Exactly! CG is critical for that reason. Mine is at 125mm. It takes very little elevator to pitch the nose up, even at speeds down to my typical touchdown of 20 kts.

Dashware. It has stock instruments or you can use the provided tools to make your own. Just plug in your telemetry data and mp4 video. Best of all, it's free!

@@rcnfo1197 I've already spent a couple hours experimenting with gauges.

@@rcnfo1197 Now I need to setup my FrSky GPS etc...

You should get much better performance than mine, especially if you use lighter packs. My WCL is 21 due to heavy 6200 mAh packs, backup battery and telemetry on board.

Thanks! It's a FrSky airspeed sensor, ASS-70.

It is an awesome jet. It's been my favorite, too! Thanks for the comment.

Yes, it is! Only 200 feet long. It's set up mainly for small EDFs that need a smooth surface to take off. My 80mm Avanti needs about 300 feet to land, but I've seen smaller jets land and roll to a stop on the 200 foot runway.

You're welcome! Thanks for watching.

Thanks for stopping by, Greg!

Yes, that would definitely help. For this video I wasn't trying to do a full stop on the geotex, just practicing touch and go's.

Thanks. Yes, that would have been good. Sorry I didn't think of that!

You're welcome! It gets easier with practice. New sequences are always a challenge. A caller helps.

Thank you!

Thanks. I earned my wings from the Navy as an NFO and also practiced stalls while working on a private pilot's license. But that was a lifetime ago! A lot of research went into this series to make sure the information was up to date.

Thanks! Have fun with the Viper!

Sorry it wasn't clear. This video, Part 3 of 6, was an attempt to provide an explanation why jets behave the way they do when slow. It is more theory and physics than practical advice. For that you can skip ahead to the end of Part 6, where I provide a list of tips for landing: ua-cam.com/video/wy5blr3g5s4/v-deo.html

@@rcnfo1197 Ok thanks 👍

Thank you! Appreciate the comment.

Thanks. We had a thunderstorm come through just before sunset that cleared the air (and soaked the runway!), but just after sunset fog settled in. Some of the guys were joking I needed an IFR clearance to keep flying. The fog was mostly gone, though, by this flight.

Thanks! Not a good landing, but I was happy to get it back in one piece.

It was! These jets are hard enough to see in the day. At night the lights really show well, which gave me enough confidence to try some aerobatics. Boy was I wrong! It needs a good tail light and landing lights. But no more night aerobatics for me!

@@rcnfo1197 Yeah, they’re too fast for those little LED’s. I can fly mine after sunset, but not more than 30 minutes after sunset.

Thanks!

Check your CG. If the plane has a forward CG and is trimmed for level flight at cruise, it will climb at higher speeds.

@@rcnfo1197 makes sense now haha that’s exactly how my plane is configured when I fly. So u would suggest putting the cg a little more aft and trim it down as well? From what I know some characteristics of a further CG will increase cruise speed but will also make the aircraft have undesirable & unstable stall characteristics? I guess I’m trying to ask if it’s a good idea to put it further & it that’s what you’re suggesting. I’m sure it depends on the aircraft as well, I fly an edf jet.

@@gcomm7536 Check out Part 1 of my video series on landing an EDF jet (By the Numbers). I talk about CG and how to check it in flight.

Thanks for noticing!

Thanks! Glad it's helping. The camera is a Mobius. Weighs about 1.5 ounces.

Much appreciated! Thank you.

LOL! I was curious how much the surfaces move in millimeters. The Position Indicator is precisely calibrated for that. But yours is the best possible answer, especially if you want to do these rolls just feet off the deck. I haven't got that brave, but a fellow club member was doing just that at our recent EDF Fun Fly. His Avanti wingtip in knife edge was about 6 feet from the ground and never wavered. He was also doing slow rolls and point rolls that low. That really set the bar for me! I'll need a lot more practice, though. In this video I lost about 20 feet at one point.

@@rcnfo1197 At the age of 73, my eyesight and reflexes keep me at least 50’ up..

@@txkflier That's fantastic! 50 feet at 90+ mph doesn't leave much room for error. In the video I'm at 80-100 feet, and that felt low!

Thanks, Greg!

Thanks! I just subscribed. Looking forward to your flights.

Where were you when I made the first flight like that? Could have saved me all the trouble of making this video! LOL Thanks for spotting that.

Thanks for watching!

Thanks. Glad you enjoyed it.

Welcome aboard! Thank you for your thoughtful comment. Having flown both I like the ability to walk away from a crash. Or, as you pointed out, take a long walk to the crash. That's a good time to think about what went wrong and what could be done differently next time.

Thanks, Dave! I got a chuckle from your comment on that next landing. Ha! But it was true! I swear! LOL.

Yes! Get yours flying again. It flies well enough to practice new maneuvers while being cheap enough to not worry too much about crashing. The perfect beater plane!

@@rcnfo1197 Well, I do have 17 other jets.. 😎

@@txkflier I can't even imagine how you keep maintenance records on that many jets. I had some kind of telemetry malfunction at the Jet Jam that I'm trying to sort out. Hopefully it was just the voltage sensor, but I'm beginning to suspect the problem may be with my transmitter. Multiply that one issue by 17 and I would have a headache for sure.

@@rcnfo1197 They mostly have Spektrum AR636 AS3X/SAFE receivers and no telemetry. A couple of them have AR637T’s with Avian ESC’s that tell me voltage and current draw. Do you have a video where you explain your telemetry and gauge setup?

@@txkflier I suspected that with that many jets you might want to keep things simple. I occasionally get asked about my telemetry setup and gauges. The process to display them is a bit complicated, so a video explaining that is a great idea. If there's enough interest I will do that.

Thanks! I'm using Dashware to display all the telemetry data. It works with any format or source. It allows you to make custom gauges in addition to their own. It's free to download and use.

Thanks, Dave! It was a good experience. Glad everyone got through it without a mid-air this time.
