Official Freewing 64mm Lippisch P.15 Thread

Yeah Im pretty lucky here. People pretty much do their own thing. The local police station is on the other side of the park. Never any problems. Of course I am the only one I know of that flies there. I'm also reasonably conservative in my flying. I just don't want to bring undue attention to myself. Im not a look at me kind of guy. If there are people around I just go to another place. Its probably the largest field I have though.

As for the price. I will have to check. The ones I saw were in the 3 hundred dollar range. Way to much for me. I wouldn't enjoy flying it for fear of smashing it up. LOL
I was watching a video about the Mig from Boozer or something like that. He was saying it flies so stable he doesn't use a stabilizer in it. Of course much better pilot that I. I did put on in the Dora mostly to help with the wind. I put it on an on and off switch. Let me take a look at the umx stuff.

The UMX Mig 15 is pretty cool. Its also pretty small. There are pros and cons there. i have a Eachine 15" p51 with stabilization and any wind really kicks it around. I have flown it in 7 or 8 mph wind but it was not fun and at one point the wind took her away. Was lucky and was able to fly her out of the problem but the actually happened twice. The P51 is a fun flier though. You have to keep er in pretty close. I would imagine the UMX Mig 15 would be about the same. Another plus is it is easily transportable in the box like my P51. Not discounting anything but right now I think she may be a bit to small for me. I kinda like the 30" size planes. Small enough to take camping but large enough to see and a bit easier to fly. All my flying is done on grass, well 90%, anyway. I know I can take the gear off. Still goin back to the P15 though. Always open to other ideas though. If I can fly the P15 at lower speeds she may be what I need. Idono but again still open to suggestions.

Thanks. Sorry F-86. One of the parks I fly I have been there for years. No problems so far but that was all prop stuff. I would guess its about 5 or 6 football fields in size where I fly. Its located at the end of a much bigger pard area where people jog and such. Not to many people around but the area I fly is kinda close to the tennis courts. No one has even batted an eye with my planes so far. I don't want to ruin a good thing. LOL I just bought a FW 190 Dora yet to maiden. This too will be pretty quiet. I was lookin at the the Horizon stuff but its a bit out of my price range being new to EDF. Just asking cause I really do not know. I thought the p15 has a pretty wide flight envelope. I'm not a balls to the wall flyer even with the prop stuff. Is it within reason for noise at lower speeds. I can rip it when no one is around or upon occasion. Just asking thanks

Oh how about the Freewing mig?

The Dora is the same price as the UMX Mig-15 and the Citation is a few dollars more. In many ways, a small EDF is safer than any prop plane in that it is less likely to cut someone if you hit them. The little Freewing Mig would be a nice plane, too, but it's a PNP so if you want it to be stable for a hand launch, maybe put in a stabilized RX or just try it first without a stab to see how you manage with it.
I can't speak for the park you fly in. I just know that it's not recommended to fly in any public park in my city even though some people do fly small planes in a few of the bigger parks but they have to be very careful. Law enforcement here looks out for such activities.

Think about my first EDF. Looking at the Panther, F85 and the P15. Actually I am leaning towards the P15. I have watched many videos on these planes and it seems the P15 seems to be a bit quieter that the others. Is this true of just comes out that way on the videos? I know these things are not inherently quiet but I fly at parks and need to keep the noise down as much as possible. It sounds like at slower speeds the P15 really isn't to bad on noise. How about the other two?
This would be my firs EDF. What would you suggest for a park flyer kinda guy?

thanks

If this is your first EDF and you are looking at something you can discreetly fly in a park, take a look at the Horizon Hobby line of UMX EDF planes. They are small and light (more suited to a park where you could get yourself into trouble with the authorities) and not too noisy and easy to hand toss. They have built-in stabilizers that are good to go out of the box. They currently only sell the Mig-15 and the Citation but if you can find a little A-10 in a hobby shop, that one was really nice. Horizon Hobby products are sold at almost all local hobby shops and they can get them in for you.

The P.15 needs a good toss at high throttle or it'll auger itself into the ground. Once in the air, even at lower throttle, it's still quite fast. I don't think you want a really fast EDF in a park. The small 64mm Panther, with its stubby little wings may be hard to get into the air without drama. It can fly pretty fast, too. Did you mean F-85? It's a goofy looking little plane that was carried under the belly of a big transport plane and launched by letting it drop. Or did you mean the F-86 Sabre? I've seen many of these in 64mm and smaller and they are underpowered and also hard to launch because they just don't have sufficient power to get flying unless you throw them hard like a football and that can cause them to roll into the dirt. The bigger ones (70mm+) have retracts and they don't like grass - again not suitable for a park.
Don't let "park flyer" fool you. It doesn't mean you can fly them in a park. Many local, state and federal regulations will forbid you from flying most RC planes in a "park". There may be exemptions for an RC aircraft under 250 grams.

Well long story short I had a really nice third flight with my p15. The first two were "interesting". The maiden involved taking off and having to land less than a minute later when I realized I had left the vtx in low power mode. So I lost the picture quickly, ripped off my goggles and landed LOS and did a bad job of that banging up the nose and putting a slight tear in one of the intakes. So repairs were done. The second flight I was able to do the autotrim in INAV and get it flying straight in level in manual and acro modes. The landing was better but the p15 likes to slide forever, and it slid through field and into bushes. This time putting 3 dents in the port wing and also bending the edge of the left elevon. So boiling water and a little bit more glue and back for the third flight. By now the Jet is looking 10 years old. But third time was the charm. I did the autotune flight for INAV which involves violent stick moves in each direction (which was alot of fun) and the jets flies really great. Rolls were really true with no dipping. Pitch lack authority in comparison but that is not unusual.

I've ordered another one because I want to change the layout of equipment. I know exactly what has to be done now and I'm pretty sure I'm done beating the heck out it lol. I was going to buy the foam parts only, but the whole pnp is only like 10 more.

ps I ended up cutting away the front "glass" on the canopy as it degraded the video too much. It didn't look bad on the bench but in flight it was no good.

First of all, be sure to plug the cheaters, or it'll still dive on launch. Don't do a wrist snap and impart a rotational force as you release. it's surprizingly easy. I've got a couple of larger planes (70 mm Durafly Vampire, and a 70mm Rc Lander F9F Panther) in the assembly line that I intend to try with this method. I grasp with my right hand, finger tips about 1/3 of the half span in from the wing tip, thumb on the bottom and other 4 fingers on top. Gentle acceleration, don't try to "whip" it. You can see how gently I threw the P-15. Practice with a length of 1X6. When you can sidearm it without introducing any significant spin to it, you've got it. The Mirage should work fine. Deltas do great in slow high alpha flight. A little up trim on a switch, full throttle as you start the swing and give it a go..

I use a side arm launch on all my small flying wings.Easy Peasy

I have never been able to perfect that kind of throw. The thing usually crashes and burns. I'm more of a Frisbee thrower but only for wings and underhand throw for things like pylon racers. This one, I keep the hand holes for launching. It's fast enough as it is. I do, however, have a Mirage that I've removed the gear that I need to figure out how to throw it myself. So far, someone else has baseball chucked it for me. It's a bit on the heavy side and awkward to hold to self throw.

[davecee]

If the hand holes are plugged, how do you hold it to throw it? This plane can, at times depending on the how it's thrown, require quite a good toss.

Ok all finished. I put the matek fc in the cockpit and I regret it somewhat. For one it makes getting the cg tougher with a larger battery and also, there's no way to make the wires neat because they have to pull out whenever you remove the canopy to charge the battery.

So it's ready to fly and it should be fine, but I will probably buy another cockpit and move the FC to the top of the fuse behind the hatch which will require cutting a large section of foam out to be able to get it back there (and gluing it back on). I will also have to connect a micro usb extension and leave it connected to the fc because once installed it will be really hard to get to it. But it's the better way to go overall.

Also cutting all that foam out of the canopy weakened it, and I'm afraid it might vibrate in flight causing problems for the FC. I'd make a hatch on the fuse to be able to remove the FC as needed but that might weaken the fuse too much so I'd rather glue it back together once installed.

Here are some pics of my IB crazy launcher with some special 3D prints I designed to be able to use it for smaller aircraft like this one. As an edf and heavier, this would require a really strong throw. The launcher is much more reliable.

I made a cart to launch mine as I really don't like hand launching DF planes plus it was a fun project.

the 4 cell fan/ setup for the 64mm is EXCELLENT !

billyd Welcome to Hobby Squawk!

I designed our P.15 to be able to fly without the aux inlets, and it's true that without them and thus less turbulence, the model flies faster. The tradeoff is your static thrust available during a hand launch condition. With less airflow readily available to the fan, you'll need to help "feed" it, with either a faster headwind, faster hand launch, or both.

The plane is beautiful, very nice design! I just have to experiment. I've added a rudder (which I guess a lot of people do) and I put a functioning airspeed sensor (Matek ASPD-7002) pitot in place of the plastic "antenna". I also put a matek f722-wing flight controller and gps. Running INAV. Using a tbs unify pro32 vtx and a runcam racer 3 camera in the cockpit, and a TBS crossfire nano receiver for flight control.

I won't try to hand launch it. I don't think I'd be able to. I have a bungee launcher I built copying this: https://www.youtube.com/watch?v=G-8I01-FTx8

Ps any plans to release a bigger version of the P.15? Like a 70 or 90? That would be amazing.

Actually there is still a fair amount to grip. More than on many of my aircraft. However mine has a full fpv setup, so I will be using a bungee launcher.

[billyd]

Good work billyd, thanks for joining squawk and nice work on the .stl. I never tried to do anything to my lippsich's. But I may give these a shot just for the heck of it

Thanks. It fits better than in the photos. I've heard plugging the vents will stop the throttle from changing pitch and makes the Jet faster. We'll see.

Hi folks. I just got this plane and joined the forum. I've read people get better performance with this jet blocking off the hand holes. So I developed a 3D printed design that matches up pretty well. Just glue in place. Attached is a picture of them in place and a zip file containing the stl to print. Enjoy! [ATTACH]n249171[/ATTACH]

Hey guys, I'm looking for a first EDF. Would this be a good first? Thanks!

TerryC Hi Terry, JayP is right, I wouldn't recommend the P.15 as a first EDF. On the one hand, it's a very docile and stable flyer at low throttle setting, which is ideal for beginners. But on the other hand, it's fast and higher throttle, and it has a slim profile as a flying wing, so it can disappear quickly. Both of these characteristics, "Fast" and "Disappear Quick" are not ideal for beginners.

The Freewing 64mm Panther is a better first option, or the 64mm F-22 or 3s F-18.

[JayP]

Probably not, honestly. It’s pretty small and can be maybe a little too quick/responsive, and has a quirk or two that some solid EDF experience will help temper. For a first one, maybe a F86 or Viper from freewing or eflite respectively, or like an A10.
