    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! 😝

    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

    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.

    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.

    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.

    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.

    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.
