Giant Balsa Catapult Glider!

[@NighthawkGliders]

Ok, Josh, we got to admit that is a fine-lookin’ bird you got there! Nice craftsmanship and nice paint! I don’t blame you for launching it easy.. your launcher is sketch-city! We can’t say this, “ended it,” but we were happy to watch you so excited about it, you made a funny video in the rain! Lol! 😝

[@joshuawfinn]

No, I don't think anything has ended, but it sure has started! I can't wait to fly them together!

[@JohnBorlaug]

Very much fun here! I love your opening with Hope too!:D

[@joshuawfinn]

We had fun with that. Other than the terrible weather of course. ;)

[@GrandadIsAnOldMan]

Brave to take it out in the wet weather like that but that is a beautiful glider. I haven't had time to build the Carbonettes you sent but I will get to them. I want to do justice to the Aleda too so there will be more videos to come.

[@joshuawfinn]

Take your time and enjoy the process. Thanks for your work on the Aleda; I'm planning to make some updates based on your findings. :)

[@LO-rc6le]

Hahahahahaha! That put a huge grin on my face. Thanks for sharing the positive vibes and fun. I am guessing the next "launcher" will be a slingshot type. I can see it now

[@sandfac3427]

Whoa. Talk about putting 1/4” balsa to good use. I hope you get more flights out of it in good weather.

[@AeroCraftAviation]

Yeah, I've found 1/4 balsa to be handy for bigger gliders. I have a few videos of DLGs I've built with 1/4" balsa on my channel.

[@itrealnibba5276]

This looks like a lot of fun!

[@AngryHybridApe]

The cleaners called. They got the bloodstains out of your clownsuit. But they said this is the last time they'll do it.

[@FFND16N]

Just seeing this 3 yrs later...you two(..or is that 5?!..)

[@joshuawfinn]

We definitely had fun with this one!

[@thebrowniesaur22]

I really thought this video was recorded in 2004 or something. Something about it gives that vibe. Great video!

[@joshuawfinn]

Thanks! It was practically filmed on a potato. 😅

[@GusLandy]

It has fairly modest aerodynamic characteristics.

[@karimramezani953]

Why do you censor when adjusting the wings, etc.?چرا هنگام تنظیم بال ها و غیره سانسور می کنید؟

[@joshuawfinn]

I've got several videos showing the trimming. This one was just goofing around so we weren't really doing trimming work.

[@RedfishInc]

I remember when I was younger and I'd stay up all night building a rocket or a glider or a rocket glider... a boy and his toys.

[@karimramezani953]

These details are valuable to us این جزئیات برای ما ارزشمند است

[@masbeetleboy]

Okay, you just gotta make a kit for this glider. I can see so much potential for this thing, from free flight to rc gliding to rc motoring.

[@joshuawfinn]

We'll see what happens. It's a good bit of work to source the necessary wood and tapered carbon booms, so I need a fair number of folks expressing interest before I can begin pursuing it.

[@masbeetleboy]

Build it and they will come. Trust me on this.

[@MrArcher0]

Lmao! Best opening yet

[@Glicksman1]

Years ago I launched from a high-start a Goldberg Gentle Lady that I built ultra lightly Well, after that I was sold. That lovely airplane climbed like... well you know. I quickly found lift and it thermalled until I was simply tired. Great airplane and that high-start was magic. Best to you and your family.

[@jasmijnariel]

Goldberg made some great stuff. I had the "elektra" but made it a bunjee launched glider, with a balsa nose. It was my first build, and after 3 months i did a competition with it and i won. I kicked the european f3j champ his ass with my cute balsa rc glider🤣 I really miss that glider, but it never survived a midair with a 6kg acro glider

[@billkuhl442]

I wonder how it would do on a hi-start. At the Nats we were using just 1/16" rubber for hi-start glider event. My 29" Retro Gnome works well on that but people were flying much larger gliders on that rubber.

[@joshuawfinn]

Oh it could definitely do that with the relevant retrimming, but that wasn't really the goal here. More than likely this model will end up converted to traditional discus launch once I've had my fun with it.

[@billkuhl442]

I think it is fun to build and fly models that are not for competition. I want to get the rocket glider kit going now that Nats are over but I have some repairs to do.

[@joshuawfinn]

It's important to have a lot of different options, and to show the goofy stuff that we do when the flight cards have all been taken up. It also provides a chance to push the performance of our planes and explore ideas that get ruled out by competition formats.

[@matthewweinle8639]

Joshua, I am about to finish a DR Models Rare (with 2 Channel RC added to aid trimming) - think FF 36" span tissue covered towline/bungee launched glider. My question is which surface finish works best in your opinion i.e. rough or shiny?

[@joshuawfinn]

Honestly I haven't been able to tell a difference. Shiny definitely looks better though, if you can get a smooth covering job.

[@matthewweinle8639]

@@joshuawfinn Thanks for the response, will probably try shiny (i.e. Oracover Lite as opposed to tissue on my next glider).

[@jayashreedhone7692]

Thats really great, I have also made one like this and it flied great👍😉

[@carlcrutchfield5094]

Hello,at some point in the future could you please do a video on how to install the proper rubber motor , I'm having such trouble with this, thank you so much 🛬

[@joshuawfinn]

carl crutchfield I'll do that. :)

[@carlcrutchfield5094]

@@joshuawfinn awesome

[@tomshiba51]

Joshua, did joining two pieces for the chord provide an easier way to sand the airfoil?

[@joshuawfinn]

tomshiba51 it can, but in this case it was a matter of not having any 6" wide wood.

[@poisontoad409]

Cat's Meow flight.

[@PilotRod]

I v done gliders that are larger than that the largest that I've built was 6 ;7 feet it flew good of the hill

[@joshuawfinn]

The bigger the better!

[@walterhoward5686]

How much weight does the paint add ?

[@joshuawfinn]

Maybe a gram or so. Sealing with varnish usually adds 4-5g on a model this size, paint is applied very thinly, just enough to give it some color.

[@daviddavids2884]

thanks for posting. good work. here are some things to consider. quadra-hedral. yuk. it is an Inefficient wing planform; owing to the Increasing Loss of Lift, towards the wing tips. because it is Impossible to Correctly manage the dom of cf, it is Not a good choice for a tail boom. EVER. suggest the use of Correctly tapered Spruce for the tail boom. the tree landing ended what, under all the circumstances, was a very good flight. consider whether a 'slower' profile should used, in the main wing. at 6:05, the proportions of the tail boom are wonky; ; the tail boom length Should be reduced by, about, 'one horiz-stab chord'. if a more efficient wing planform and an Appropriate Profile are selected, the main wing chord length should be reduced, a bit. to the extent practical, the profile of the main wing of a model aircraft Should Always Resemble the clark-y(v1) profile. period. the original clark-y profile thickness is 11.7 percent of chord length; with max Thickness at 30 percent of chord. on a glider, a thinner version of the clark-y can be used. in any case, the profile of a model aircraft wing, where the generation of LIFT is desired, Should Always be Thickest at 30 percent of chord; the only exception might be where a slow-flyer planform has been used. ( these are not opinions. ) cheers googletranslate

[@joshuawfinn]

David Davids, sorry, but those are opinions. Ones which violate 70 years of history in catapult launched free flight models. When you exceed Stan Buddenbohm's and Lee Hines's contest records, you can then claim something other than opinion status.

[@joshuawfinn]

To those watching, here is a breakdown of the above:1. Four panel wings have been used on almost every US and UK outdoor Nats winner for at least the past 15 years. The Cat III and IV US and FAI indoor records are all held by aircraft with four panel wings.2. The pultruded boom on this glider is too weak, as I mentioned in the video. CF however is the absolute best material for fuselages, period. I don't know of a single Nats winner or record setting glider in the past 20 years that has not used a carbon tailboom. In some cases, the entire fuselage has been carbon, such as in Jim Buxton's record smashing Amalgam.3. There is no slower wing profile for outdoor flying than the Stanfoil. It is the best airfoil ever produced for lightweight outdoor gliders under 1m wingspan.4. The tail moment arm is well within the statistical norms for Nats winning catapult gliders for the past 3 decades.5. No competitive glider since at least 1935 has used a Clark Y wing. It is wholly inadequate for the flight profile of a catapult or hand launched glider and is hopelessly outdated even on towline and similar models (but at least isn't quite as terrible in that case). The accepted optimum high point on HLG and CLG models under 1 meter span is 25% chord.If you are wondering why such a fierce reply, well, I'll tell you: you came across as a self proclaimed expert commenting on a video beginners are likely to view. The information you presented directly contradicts the past 70 years of slow speed aerodynamics research, and I cannot allow that type of thing to go unchallenged in this context.

[@daviddavids2884]

your reply is Irrelevant. you can KEEP your effing categories. my OBSERVATIONS are Not opinions. jeez. just how does one 'violate history'. lmao.

[@joshuawfinn]

Fine, David, please share your competition history and your engineering qualifications.
