Rubber Powered P30 - Trimming and Flying at the Soccer Field!

Hey guys! In this video, I take my P30 out to the soccer field for some flying. I do a short trimming session, and briefly describe some of the aspects of adjusting a free flight aircraft for level flight. I also notice and describe an odd flight characteristic which seems to be caused by wind or turbulence.

You couldn't ask for a nicer flight than that last one. Just beautiful!

[@AeroCraftAviation]

Thank you! Although I’m positive this plane can do better, so stay tuned for more flight videos! :)

[@elblitzb]

Las saturday i went to a pine forest near my home and i took a rubberband plane that i bought impulsively a lot of time ago (reminding the ones that my grand father bought me when i was just a kid).... i played in the exact way that 25 years ago and the sensation when you calibrate the perfect flight was the same.... very beautiful videos you got there....thanks for not adding anoying music. Regards from Chilean skyes.

[@AeroCraftAviation]

Wonderful to hear your story! My father's family is from Chile; what a beautiful place, some great landscape for flying model airplanes. Cheers!

[@jessyeaviation9201]

She flies so perfectly that it looks like she 's guided by your thought. Thumbs up for the trimming, nice video !

[@AeroCraftAviation]

Thank you! Glad you enjoyed!

[@GrandadsOtherChannel]

There is something very special about rubber powered free flight 😍👍

[@AeroCraftAviation]

I completely agree. There’s always that underlying hope that it’s gonna pull up and manage one more circuit! :)

[@luke_atthat]

Incredible fly, Perfect trim, and Great explanations

[@elizabethconant9971]

This is one of my top favorite crafts of yours. And I really appreciate the accompanying narrative - it helps luddites like me to understand what's going on. :)

[@AeroCraftAviation]

Haha cool! Glad you like it. 👍🏼👍🏼

[@fierceflyer5]

Thanks for the trimming video and explaining what and why you were doing. Great video for beginners!

[@AeroCraftAviation]

Glad you found it helpful! :)

[@ludwigvanzappa9548]

Beautiful ! Thanks man !

[@AeroCraftAviation]

Thank you!

[@billkuhl442]

Great job on the P30, hopefully you have a winder. I just single channel RC in a P30, but I did design it like you have. Always enjoy your videos.

[@AeroCraftAviation]

Thanks! Actually I do have a wonder, but it’s only for indoor planes. So I have to handwind my P30. 😭 Glad you enjoy the videos!

[@allenmoore9848]

Looks like a tough plane that can handle a bump or two. You have done a good job getting it trimmed out. I trim out my planes gliding first, then adjust motor offset to trim under power.

[@AeroCraftAviation]

Yeah, I built it tough and robust, because I needed a free flight plane for a model flying event I was going to attend, and had no others on hand. So I knew if it was gonna be my only model, it had to take a few crashes. In fact, during that event, there were some strong gusts up to 20 mph, one of which dashed it against the pavement parking lot, but it sustained no damage! I find that trimming larger outdoor FF models with glide-tests has a rather limited degree and efficacy and accuracy, and often trim adjustments made during gliding will need to be altered with power, making for extra time and effort required. But certainly if motor offset is a possible trim parameter, it can be a big help. With this plane, I don’t have any control over thrust angle, so it’s a rather limited aircraft in that sense.

[@Prowlerook]

Inspiring!

[@AeroCraftAviation]

Thank you!

[@Colin399]

Nice model

[@AeroCraftAviation]

Thanks!

[@robn2497]

I love this guys logic, "because gravity is a thing". NOT sarcasm legit made me laugh :)

[@loganreuter6072]

Wow nice plane and flights! I think the weird stall to the left isn’t a gust or a thermal but something with the design. My p 51 mustang does something weird like that too when I hold down the elevator and keep holding it. After it stalls it will go into a spin if I keep the elevator down. Maybe since the rudder and was elevator are constantly deflected it does something like that. Idk. Anyway one thing I was wondering is how you make your props. Happy flying!

[@AeroCraftAviation]

Thanks! I believe the thing with your P-51 is just on account of the instability inherent to a low-wing warbird. It tip stalls like most low-wings, then because of the poor yaw stability, it easily looses its forward velocity and goes into a spin. The issue with my P30 is that the propeller produces a torque to the left, and the rudder tries to overcome that and produce a right turn. But when the aircraft stops turning right, the upward pitch causes it to slow down, and when it slows down, the rudder looses efficacy but the torque stays strong. So as it pulls up and gently stalls, the torque pulls it over left. Then as the airspeed increases again, the rudder regains its efficacy, and the aircraft banks over to the right again. It might not necessarily be due to air currents, maybe it just had a bit too much up-trim or not enough decalage, not sure. Anyway I’m pretty positive that’s whats going on, although I could be wrong.

[@AeroCraftAviation]

As for my props, i just use plastic props. Saves a lot of time and usually yields better performance than anything I could carve.

[@snorman1951]

Great job! Do you have a mentor? I ask because I've seen an older individual in some of your videos. Grandad? Uncle Perhaps? You've progressed a lot in a short time.

[@AeroCraftAviation]

Thanks! Yes I do have a mentor. Jesse Aronstein, father of the well-known aeronautical engineer David Aronstein, and an extremely knowledgeable electrical and mechanical engineer himself, has been mentoring me on-and-off for the past 4 years. He is the president of the Electric-Powered Aeromodelers of Schenectady, and he arranges all the indoor flying sessions at he armory where many of my videos were filmed. But seeing as we live over an hour apart, and school and my other exploits leave me busy for usually around 10 hours a day, we rarely have time to get together, and thus the vast majority of my improvement has come from my own efforts and studies.

[@sumantabhowmick.4128]

Good to watch..... far better than dlgs ...😀😀

[@sumantabhowmick.4128]

@@zacapelt1234 completely agreed with u.... actually I am talking about this channel owners dlgs.... his rubber powered and electric slow flyers are just awesome... he is a master builder of those but I personally not like much his dlgs.... honestly.... sorry for that.

[@AeroCraftAviation]

Thanks! Yeah I get bored of DLGs sometimes too. These rubber powered ones are good fun. :)

[@AeroCraftAviation]

Thanks! I’ve been considering making a beginners DLGs step-by-step tutorial to explain in more detail how I do what I do with building DLGs. I just gotta get around to it. 😅

[@AeroCraftAviation]

That’s ok! Everyone has their preferences! :)

[@sumantabhowmick.4128]

@@AeroCraftAviation good to hear that u will show step by step build... lot of us can learn from that... hope somtimes u will add rubber band with prop or some electronics to those mighty DLGs..... ha ha..... never mind... have fun

[@altbob]

Nice video! How's that ornithopter coming? We have an indoor Flyjam Dec. 7th!

[@AeroCraftAviation]

Thanks! Well, lemme just say, one step forward, two steps back. 😭 But I’ll get it sorted out and finished by the Flyjam for sure!

[@altbob]

Let me know if you want any company during the build. I wouldn't mind making one side by side with you. I've been thinking about some kind of RC Monarch butterfly project all summer.

[@altbob]

Did you see this one? It seems to have a variable thrust set-up between two motors, running the left and right wings respectively: kzbin.info/www/bejne/apXYgIGqqqx4pZY

[@AeroCraftAviation]

That’d be cool! I s’pose we could just both make ornithopters of our own design, and then bring them to the flyjam to test fly them. :) You make your butterfly, I’ll make my pterosaur, and we’ll try to keep yours from migrating and keep mine from eating yours. 😂

[@altbob]

I'll see what I can do. There's a lot going on in my shop at the moment. The ornithopter butterfly I want to build is quite complex and I think I may need to get a 3D printer to make the gears and parts.

[@coffeyhj]

Rubber Powered P30...Was this a specific kit or design? Thanks...

[@AeroCraftAviation]

No. Just something I threw together for a weekend free flight event.

[@VichevJr]

Pro or non pro p30?

[@Colin399]

It flies great, but l think if you cut the rudder down in size it would fly even better, it’s a little tail heavy.

[@AeroCraftAviation]

Good observation, I guess that is a a good bit more rudder surface than it really needs. Thanks for pointing that out! :)

[@diegoconti7166]

Hola tenes que provar el planeo y giro sin potencia y despues ajustas con la prompa

[@AeroCraftAviation]

No estoy seguro si entiendo completamente. Pero sé que hay problemas con el giro, como un alto ángulo de incidencia y una velocidad muy lenta.

[@towitowi1]

Jak dużo można osiągnąć optymlizujc ustawienia, podoba mi się :)

[@AeroCraftAviation]

Dziękuję Ci bardzo! Cieszę się, że Ci się podoba. :)

[@brianamato1078]

Terrific. Don't know the P30....I'll have to look for the plans

[@AeroCraftAviation]

No plans are available yet. But I might draw them up if I have the time. :)

[@chez4504]

Check wing torsions..

[@AeroCraftAviation]

Wing is very stiff; no possibility of deformation under typical in-flight torsion.

A P30 needs a fuse, according to the NFFS.

[@AeroCraftAviation]

Ah you mean a rolled fuse? Huh I knew that was commonplace among P30s but was not aware of it being a requirement. Makes sense. I'm surprised no one has called me out on that before. Duly noted!

[@nanaofficail197]

Buy how much my friend I'm Cambodia

[@AeroCraftAviation]

Sorry, I don't sell these aircraft. :)

[@daveb7811]

A thermal catches one wing and not the other ? C'mon.

[@AeroCraftAviation]

Yeah that's usually how you know you're near a thermal if you're flying an RC glider for example, if one wing lifts up you just turn that direction and you'll find the thermal. With free flight airplanes they'll often run into little pockets of sink or lift that cause them to bob side-to-side.
