What can I say Joshua You are a natural teacher , I wish when I was young the old timers were great but I am afraid lots of them when they wrote articles on similar subjects with the good intentions of passing on there knowledge but for some reason were not the best teachers they got to technical and it never was very clear to the newbies I my book you have a way to get good information across Thank you Herb

The way your oldest son keeps throwing those aircraft. He has an arm on him. I can see him being a powerful quarterback someday. Keep up the good work. Great mother and great father. Best team work ive ever seen.

That looks like an absolute monster of an Embryo. Still haven’t designed one yet but this is making me want to!

@joshuawfinn 4 жыл бұрын

The big things with this one are its lightness and simplicity. Even the front and rear of the fuse are interchangeable, so there are as many duplicate parts as possible. Built with care it's a sub-10g airframe and carries its own weight in rubber, swinging a big, slow prop. Ive actually maxed these launching into sink because the climb lasts over 2 minutes. The glide is pitiful but it's still good for well over 3 1/2 minutes in dead air.

Streamer dethermalizer! Yes! I have never seen a wing streamer dethermalizer used like this. But I have used similar devices with model rockets!

Thanks for your wonderful video! I am just wondering why outdoor models don't fly with the torque?

@joshuawfinn 2 жыл бұрын

Outdoor models are pretty rigid, so you don't get a bunch of wing twist creeping in as the torque goes up. As a result, you can fly them very safely to the right, which provides a higher climb rate and prevents them from torquing in to the left anytime things aren't exactly perfect.

I'm new to getting into rubber band planes. Why put a wick and have it burn the rubberband and have wing pop off? Why not just glide down?

@joshuawfinn 3 жыл бұрын

That's so you actually get it back. If you put it in a thermal without lighting that fuse, it's gone forever.

@mattluszczak8095 2 жыл бұрын

Hey bud why is the cg at trailing edge i thought it was allways 1/3 back from the leading edge?

@joshuawfinn 2 жыл бұрын

That's what they always tell you, kinda like that textbook crap about the curved top of the wing making the air go faster to produce lift. Reality is that none of it is true. For CG purposes, tail size relative to the wing dictates the optimum CG, as given by this formula: themmmclub.com/wp-content/uploads/2012/11/Tail-Volume-Coefficient.pdf

embryo is FAC I think? Who are the last to maintain the bom rule...

@joshuawfinn 4 жыл бұрын

Correct on both. My #1 objection to BOM is the number of models that get trashed when people die because their planes can't be flown by anyone else.

@geebee3d 4 жыл бұрын

joshuawfinn Is it FAC or AMA that has a proxy/legacy rule, where you are allowed to fly models from the estates of deceased fliers? And if there isn’t, there should be.

@joshuawfinn 4 жыл бұрын

@@geebee3d AMA deleted the BOM rule for outdoor at least 5 years ago, and NFFS and SAM were quick to follow. The result has been very positive.
