Nice job, Josh! You got that flying like a champ! I love watching you bring out the full potential of these 'models'. I hesitate to call them that because every airplane is a machine built to challenge and use the forces of nature to its benefit, so it's not exactly modeling as it is DOING. Have a great day, brother!
Thanks! Personally I tend to call them all, regardless of type, toy airplanes because if you're not having fun, you're doing it wrong. But you're definitely right--they all have a purpose and they all work on the same principles regardless of size.
That was great Josh, adding the dihedral made a world of difference. I bent in washout but no doubt that adds drag. I did not properly wind mine up because I didn't haul a stooge out, then the prop assembly appears to have some grit inside it. The rubber climbing on the hook was a problem too. I have two more planes that I will improve on. It is only 37 degrees and windy here so no flying.
If anyone could get a thing like this to fly well, then you're that person! I can see that the prop is a pretty good reason to rescue this from the tallest tree.. Way back they used to dish up sheet balsa/formers formats as semi scale, pre colour pre printed jobs and we used to buy them just for the hardware.. I don't know where you can get these props, and I'm sure there'll be many people who'd like to know! Great flight at the end, really finding some air. I wonder just how many animals do you have there Josh? Every video seems to include a new one! 🌟👍
what makes for a good "retrieval pole"...? i've tried taping together 20+ feet of half inch electrical conduit, and it is *very* unwieldy/heavy/flexible...
Nice to watch the full build and then the flight!!! Good combo videos!!! And, ha ha, just for one moment there, the match-cut from holding the chicken to throwing the plane, looked like you were glide testing the chicken!!!! Just for a split second!!! Funny!!! But seriously, great videos and fab channel!!! 👌 Blessings from the UK; Johnny 😃
One of the best flying rubber band planes I had as a teenager in the 1970s was a foam Citabria or Cessna that had a molded cavity for clay under the nose. it outlasted about a dozen motors.
Does anyone know if I thin under cambered air foll has 110 and see the Dutch roll or snap roll because I own 2 models with that problem and I hate to increase the vertical stab area at both are scale models.......ugly fin on bottom.... I would rather modify the wing or the air fall instead..... Both are rudder elevator controlled Could that be the problem?
Dutch roll is usually an issue of wing vs fin sizing issues. Check that you have sufficient washout in the wingtips. If you do, consider enlarging the vertical tail and/or reducing the dihedral in your wing. A lot of old timers have high mounted wings with lots of dihedral and this can make them very sensitive to yaw inputs when converted to RC.
Slowfly props have an extremely low pitch/diameter ratio (usually 0.3-0.5), and rubber props usually don't hit their best efficiency until at least P/D 1.1, sometimes closer to 1.6 (this propeller appears to be at least 1.5, which is what makes this plane climb and cruise so well)
@@joshuawfinn My policy is lower pitch propeller is more better/efficient. I would test it with more strands and lower turns. It should also be possible to insert a ball bearing in the APC propeller to reduce friction. It will be nose heavy, but most real propeller planes are. Maybe also use contrarotating propellers to reduce torque steer.
@@prep0wer like I said, best efficiency at P/D >1. Most full scale aircraft with VP props cruise in the 1.2-1.3 range, dropping down to 0.8-0.9 for climb. Anything lower is inefficient except in high alpha/low speed where the prop is contributing to the lift force of the airplane (why helicopters operate in P/D
More details about the plane please. About 10 years ago I purchased three models made of a similar foam, a Cessna, Spitfire and a Mustang. The rubber supplied with them was junk but otherwise they fly pretty good. Problem is the ones I got are no longer made. Looking for something even remotely similar.
I had one O these back when was in school it flew in a loop but was difficult to trim and was made of foam so it wasn't destroyed and was with me quite sometime. Good starting plane yeah better then building balsa Auster that i went next i had bad building skills so it was a disaster for me never flew well.
Yeah the durability helps. Scale models are generally a pain to trim. I always tell people to start with a P-30 or a Gollywock. Easy fliers, incredible performance.
Flight video was great!....I noticed the kits in the link sold out quickly after the Flight video posted. Does anyone know where to source more kits from the Funcraft series?
Darn. Didn't know they all sold out. :( I'll keep my eyes open for more. Shoot me an email and I might be able to hook you up with a Sky Sedan if you need one.
Love the video content of this channel....would you ever consider doing a build video of something like a Guillows 500 series laser cut warbird? or...a Peck Polymers Peanut kit? It would not need to be a Long video...I was thinking if you covered mods you would make to the kit(s) to improve flight potential and of course a trimming video of the finished model would be great! The Guillows warbird would be the more challenging project....just thought I would ask, Keep up the great work!
I've got a couple more Guillow's kits in store and hope to get to them eventually. The 500 series I won't touch, waaaay too many mods required to get them to fly. The 900s require only minor mods to get them flying wonderfully. I'd love to do a Peck kit but not while they're under their current proprietorship. That's a hot mess that I won't touch, been burned too many times.
We do carry winders that work quite well, however this particular one is one of a pair Ross Clements built for us. Unfortunately it is highly unlikely that any others will ever be produced as they were very labor intensive to make. They'll also never ever wear out as they're made for massively larger loads than what we're applying
Thanks for responding so quickly. I'm a retired machinist, so I might make my own. I bought one from you about a year ago. It's fine, but that one in your video today is really nice. I don't suppose you have any plans for that one? I've thought about making my own or even an electric.
Is there some way to determine a horsepower rating for the..."engine"? There must be considerable variation between rubber bands of different thickness, length, types of rubber... A tiny dyno would be very useful. If such a thing existed. Which would be astonishing. And expensive, no doubt.
You can compute stored energy via torque vs turns while unwinding. Power then is available from the speed of the prop as the motor unwinds. There's a good article on rubber energy usage in this year's Free Flight Symposium, available at freeflight.org
Why not start by adding transparent windows instead of opaque stickers? Making the pilot go IFR every time just makes it harder, but you did find success in the end.
Hallo Josh, amazing job on the plane and very nice flights. I have sent you an email regarding the props as youtube keeps deleting my comments here. I don't know why.
Does the package and instructions have a manufacturers address where you can get more props? Check with Rob Romash at Eclipse Toys, who sourced the AMA Alpha and Beta from China. Glide testing from shoulder height is about useless. It is still recovering from the impulse of the launch when it hits the ground. I find I get better glides launching it like a hand launched glider; steep right bank, high nose. It climbs to altitude, rolls out high up and gets into a proper glide long enough that you can get a proper read on trim.

"I hate retrieving from that tree." The statement that sounds like it has many stories to go with it.
Yeah, one in particular involving Caleb's hand launched glider!

Always good to experiment with RTF kits. All the best from the UK mate 😊

I think I know which one you're talking about. Would love to find one.
Fly really nice. That is great model ❤🎉🎉🎉
Turned out much better for a factory foam plane. I originally thought the plane would fly about 20-30 seconds max.
I was figuring the same. It's been very satisfying. Impressively durable too!
I thought you had developed a new prop based DT for the foamie. Worked pretty good too!
I bought one of these here in Germany but I haven't got around to fly it. Now I'm going to wait for a nice day to give it a try. Cheers.
You'll enjoy it for sure! Be sure to use good quality Tan Supersport rubber as that does make it fly much better.
The back tail should be little bent downside so that the air will push it upwards and make the front portion lift upwards.....
Check out the "Gizmo Geezer" props with freewheel hub. They have a pin design wich eliminates the rubber climbing up the hook.
I've got a few P-30s with Gizmo front ends and they do work very well indeed.
Were you ever able to locate any of those props after posting this last year?
I was not, however I did aquire a box of the kits themselves which I will be making available soon.
Does anyone know if I thin under cambered air foll has 110 and see the Dutch roll or snap roll because I own 2 models with that problem and I hate to increase the vertical stab area at both are scale models.......ugly fin on bottom....

About the crooked fuselage - maybe it just came with built in tailplane tilt. It wasn't flying half bad when you were done with it!
It definitely did fly excellent. I wish I could find a source for more of them--it's a great little airplane.
Or use an APC slowfly propeller?
The weight also increases the scale factor of the plane.
Slowfly props have an extremely low pitch/diameter ratio (usually 0.3-0.5), and rubber props usually don't hit their best efficiency until at least P/D 1.1, sometimes closer to 1.6 (this propeller appears to be at least 1.5, which is what makes this plane climb and cruise so well)

There you go! I have a case of them that I'm going to sell off eventually.

Nice job! Nice to see a old toy fly good and well, I also have chickens lol. Nice to see more content!
Glad you enjoyed it! And yes, farm fresh eggs are excellent.
I have this model and it flies good.
Greatings from Germany near Nuremberg
Seems a lot of people have enjoyed this plane at one time or another. I'm late to the party!
Did you get the CG dialed in on that chicken? 😉
Still working in it. The clay won't stay attached!
Good afternnoon, how can I buy this type of aircraft
I'm working on an attempt to get more of them.

"I hate retrieving from THAT tree". That specific tree is a problem...Hilarious.
Yeah we have a history with that tree. Lol!
At a volume of 500, an aluminum mold might be economically viable for a prop like that
very nice always great vid thank you
Why not start by adding transparent windows instead of opaque stickers? Making the pilot go IFR every time just makes it harder, but you did find success in the end.
I mean he's gotta have that instrument ticket if he wants to be a "real pilot". But he still can't win because he didn't build that prop himself. LOL!
Ok, how did you get the spinner apart to put the good rubber hook on?
I just carefully cracked it loose by cutting into the glue joint with a razor blade. It came off surprisingly easily.
Man, that's funny! 😆
Wowers epic flight for a toy grade airplane
Yeah I am suitably impressed with it. Wish I could find a source so I could import them.

Between 11:51 and 11:54, a UFO flew under your plane.....
If you're talking about that brief streak of light, it's a camera lense issue. Annoying but it's the nature of optics.
@@joshuawfinn Literally there is a ball
that flies from right to left. Anyway, thought it was kinda cool!
Oh ffffffun! 😅
