Rubber Powered P30 - Trim Flights at the Soccer Field

[@GeneBurnett]

This might seem a little odd to such a young person, but for an older dude like me, the fact that these flights, no matter who successful, are "doomed" to return to Earth makes each one more poignant and beautiful than if it was somehow possible for the plane to glide in perfect circles forever. And throwing Erik Satie into the mix underscores the beauty and impermanence of life even more. This all might seem melancholy, and I guess it is, but I agree with Victor Hugo's definition of melancholy: the pleasure of feeling sad. Well done.

[@AeroCraftAviation]

That’s an interesting take on it. I find that the invariable finiteness of every flight’s duration is an inspiration to do better flights, and build better aircraft, because it shows very clearly that no aeronautic achievement is without its fair share of hard work and ingenuity that made it happen, shows that there is no free lunch. This is why powered R/C aircraft tend to bore me, because if you want to keep flying, all you have to do is raise the throttle; the effort is minimal and therefore the pleasure from its benefit is superficial. If you want longer flights, you can simply buy a bigger battery, or a better motor; the effort is mostly just monetary expenditure, and therefore the result is often even dissatisfying, because you know the detached, uninvested way by which you’ve come by it. That’s why free flight aircraft and DLG interest is the most; seems that they require the deepest attachment to and investment in their creation.

@@AeroCraftAviation I play hacky sack and there is a very similar thing going on. We stand in a circle and see how long we can keep this little sack in the air using anything but our hands, mostly feet. The outcome is preordained in a sense...the sack will come to the ground...we will not keep it up indefinitely...we will always "lose" to gravity. But meanwhile...before we lose...how much style and grace can we show...how connection and community can we enjoy? Good metaphor for life too. ;~) Rock on copter dude. GB

[@AeroCraftAviation]

Nice. I like that comparison. 👌🏼

[@GrandadsOtherChannel]

Continuous improvement, I remember that as a phrase often used at work, but it was clearly working here 😍👍

[@AeroCraftAviation]

Yup. I like how, with a good aircraft, it’s easy to achieve steady, visible improvement throughout a trimming session. Gives a good sense of accomplishment and satisfaction. :)

That was a very serene video. Great job! Also great job on building that flying machine. The gentle landing in the deep grass reminded me of when I first started flying RC. Me and my buddy Ben did our landing in a deep clover field for easy soft landings. We flew without landing gear so there were no snag points. Stall the plane in so you are at minimum speed. Clover landing is like landing on a pillow. I flew my first .60 sized trainer there also. Six foot wing with 14" chord, and fairly lightweight. I left two huge slugs of steel I used for building the fuselage inside without realizing it. The plane hand launches beautifully and when I level off I hear a loud clunk! The steel inside was sliding back and forth changing my CG at random. That plane still flew exceptionally well even with the extra 1.5 Lbs sliding around inside, and having a newbie at the controls. That is a good design! Got it back down safe and sound, took the steel out and that thing was amazing after that. Ben had a few good wrecks out there. Clover doesn't offer soft landings for out of control speed dives! He bought a .15 powered pylon racer that he flew so far off into the distance that it was literally a speck in the sky. And way out over some tangled swamps, So he hands me the transmitter. :-) That plane had about a two foot wingspan and was easily a mile away and only flew one speed, wide open and fast! I got it back, sort of, to over the far end of the adjacent corn field where it crashed. We found the plane in a few pieces after an hour long search. Luckily the servos in the fuselage still worked, and we could hear them whizzing when we moved controls on the radio.

[@AeroCraftAviation]

Thank you! Yeah, soft grass landings are the best. Even short grass, although it often seems soft, can be too hard a surface for landing fast or delicate aircraft. Long grass is the way to go. Sounds like a trusty aircraft you had there. I’ve never been able to get any of my builds to last more than a year or so without something bad befalling them. It’s been on my list to sometime build a robust flyer that will stay around for a while, but I’ve just got so many other projects on my plate, it hasn’t happened yet. I can’t seem to get ahead honestly; there’s always more work to be done on something, fixing crash damage, routine pull-cable changes, new finish, or something of the like. Even now that it’s sumner and I’m spending >4 hours a day at the bench, I can barely work fast enough to clear space for everything that needs work. Ugh. 😅

[@somethingelse2740]

Yes grass can be tough on planes if they are moving fast. I once had a "Diamond Dust" delta shaped plane that had a high performance .40 size motor and tuned pipe on it, so it did well over 150mph. The plane was made of a simple graphite tube configuration with a few plywood ribs and thin CA on kevlar thread wrapped tube joints. One day I was practicing 1000+ foot loops and getting them as close to the ground as I could go. Usually about 3-5 feet high at bottom of the loop. Well, one loop ended up being about 3 inches off the deck and there happened to be a bunch of tall weeds about 6" high with some kind of clover flower type tops on them. The leading edge of the wing hit the stalks and the flower tops whipped over the top of the wing and instantly Whipped and shredded the Monokote on top of my wing. Never saw anything like that before or after that incident. Monokote has a 25,000 psi tensile strength. It is tough stuff! Those weeds were doing some serious whipping!

Excellent! Thanks so much for the info; now to the drawing table.

[@AeroCraftAviation]

Glad you enjoyed. Designing and planning for these builds is always fun. Cheers.

[@myramadd6651]

That was beautifully graceful! Nicely done! I could watch it for hours.

[@AeroCraftAviation]

Thank you!

[@ricomon64]

Beautiful! I always tried to trim mine to circle left under power and circle right when gliding. Trim it to gently glide to the right. Usually, zero right thrust would allow the torque and P-factor to turn the plane to the left. By the way, that Gymnopedie really fits the mood of the video - finally trimmed and the rain starts, but still quite beautiful.

[@AeroCraftAviation]

Thank! Yeah, people are always telling me to do the left-right trim setup, but I’ve never been able to get that to work with much consistency. But I’ll try it with this plane and see what results I get. Maybe I’ll finally get a solid left-right flight pattern.

[@jimbo2629]

Left right is wrong! Right right is good for folders, but for freewheelers right left is correct! Left under full turns will swoop left into the ground because of the torque reaction. The prop turns one way and the model the opposite. It gets worse the more turns you put on. That’s why you have right thrust as well as down thrust. If you fly right right the nose will drop unless you have a prop stop or braiding. If you fly right left the transition to glide tends to lift the nose. If right right you stay in the thermal.

[@garydietz3218]

Enjoyed the trim flights and I would like to build a P 30 like yours. Are measurements/plans available? If not just some basic stats would be helpful or even a similar plan u could recommend.

[@AeroCraftAviation]

Hi there. Wing chord is 4 7/8 inches. Airfoil is NACA 2412. airfoiltools.com/airfoil/details?airfoil=naca2412-il Curved wingtip sections are 3 1/2 inches. (meaning that the straight wing section is 30 - 2(3.5) = 23 inches. Wing is mounted at 0 degree incidence relative to fuselage. Wing pylon is 3 inches high (measured to wing chord line). Pylon is made from solid 1/4 inch thick balsa. Stab is adjustable between ~1 and ~4 degrees of incidence. A tab on the stabilizer, a tab on the fuselage and a little rubber band are used to set the incidence. Insert a little shim to increase incidence. Fuselage length is 27 5/8 inches. Fuselage is a 5/16 inch sq. stick of hard balsa. A flat piece of carbon tow is glued to the top surface of the fuselage for strength. This is adhered with epoxy and stretches from the nose, 19 inches back. Stabilizer is 8 1/2 inches with 3 3/4 inch root chord. Vertical fin is....honestly I’m not sure how tall it is, but I’d guess around 6 1/2 inches. However, that is too tall. A better height would be more like 3 1/2 or 4 inches. That’s all you need really. Propeller is 9 inch diameter Peck plastic propeller. Not sure of the pitch. Nit sure of the main shaft or rear hook thicknesses. But I can tell you, they’re made of music wire. Rubber motor is two loops of 1/8 flight rubber...FAI Tan Supersport I believe. Weight with motor is around 61 grams. All covering us EasyBuilt Lite tissue. easybuiltmodels.com/ebl.htm Fixative used is Krylon. These are just some general dimensions and specs. Keep in mind, I’m not an outdoor free flight expert. If you have experience in model aviation, your guess is honestly as good as mine when it comes to this stuff. That said, I hope this is helpful.

Nice fly.regards Maciej

[@AeroCraftAviation]

Thanks! Sorry for the late reply.

[@robinboucherwonderfulflight]

Hi, You ever printed up plans for this P-30? What's your best flight with it? Great flying model. Thanks

[@AeroCraftAviation]

Hmm, never did. Was only sketched out hastily on piece of scrap paper anyway. (Built it in an afternoon to bring to an impromptu free flight event I was invited to). Maybe sometime I'll dig it out of the basement and try to document the features. I doubt I ever got more than four minutes with it anyway.

[@jankochanowski3252]

Very nice :-)

[@AeroCraftAviation]

Thank you!

[@loganreuter6072]

Congrats on 200 subs!

[@AeroCraftAviation]

Thank you! I was going to do a 200 sub special, but had some technical difficulties getting it filmed and edited.

[@billkuhl442]

Great you are designing your own airplanes.

[@AeroCraftAviation]

Yup! Except for a spare few, every aircraft I’ve ever built has been my own design. :)

[@MartyLJ57]

Nice

Nice plane..... is it home made ??

[@AeroCraftAviation]

Yes. Designed and built it myself.

[@sumantabhowmick.4128]

And did u build the previous on (previous video) also?????

[@AeroCraftAviation]

Yes. I have built almost every airplane I own. (More than 20)

[@sumantabhowmick.4128]

Then my friend why dont u post some build pic ????? Why????..... let me know who the person on Earth is stopping u from posting ur beautiful, skillful build snaps.... tell me mate... .. ur flying videos are average and common but ur build videos are unique and exceptional....eagerly wait for those...... post ur builds whatever u make.... u can post build and flying in different video but post them.... share ur skills its pure art..... If I said much SORRY for that....... Cheers

[@AeroCraftAviation]

I know I should be posting build videos. The issue is, those take time to get all the photos, to edit them together, add the text, information etc. And I have a lot of other things to do, I am very busy, and don’t have time to document every build I do. Some builds I do document.
