That is a tremendous glide on the monster rubber job

[@monkfry]

Josh talking about planes not taking over a house. . Next video, How to deal with too many boxes!! 😆👍

[@joshuawfinn]

Totally! Lol!

Fantastic video, thanks for the tips. I'm curious about the wing loading in the big glider.

[@joshuawfinn]

It's quite low. Roughly 450 sq in, 195g all up flying weight.

[@debbiramsey4603]

That was magnificent, I love gliders, dorm back then .

This video made me dig out my first editiion Model Builders Handbook given to me by my late grandfather in-law. One of the great things I picked up from this is How to Carve a propeller which I have carved many for my RC .60 size aircraft.

[@williamrobinson7435]

Yes a beautiful glide.. Thanks for a most informative video! When I was doing KK, years ago, I was surprised by the variance in weight of different rubber bands for wing attachment &c.. Keep up the good work!

[@sandfac3427]

So cool to see the Goose in good shape, can't wait to see its upcoming video. I started a Stott Cessna Loadmaster at 40" in 2017 and am finally trying to finish it up... might do a similar stab configuration.

[@joshuawfinn]

The Goose lives on! Looking forward to seeing your Loadmaster flying!

[@angelreading5098]

Josh your Spruce Goose reminds me of the Martin Clipper flying boat that I built from as Cleveland plan,only flew it as a glider but it looked stunning floating around, love your huge rubber jobbie and the way that it floats,great informative video thank you sir.

[@m.s.aviation7065]

Awesome video and cool tips! (also i dont blame the Spruce Goose harrasment)

[@sablatnic8030]

Nifty, locating the fin at the side of the fuselage, so you get interference drag from one less inside corner!

[@joshuawfinn]

Bud Romak knows how to design airplanes!

[@sablatnic8030]

@@joshuawfinn I can see! My kind of model, just enough to do the job!!

[@crashrr2993]

Great video, even though I have envious amounts of storage space, my modest collection of scale rubber crates is a growing headache. Awesome glide! May I ask what material you used to cover the wings of the Dawn Patrol?

[@joshuawfinn]

The Dawn Patrol is covered in 1/4mil mylar, specifically resin dyed printing mylar. It's somewhat hard to find but does show up on ebay sometimes.

[@crashrr2993]

Many thanks, I have long-dreamed of building a Dawn Patrol... they are a strong candidate for the ultimate rubber beast!

[@CV_CA]

29:13 Yes, yes and yes. Love it.

[@davidcornell390]

the ratio though *chefs kiss*

[@michaelrussell5346]

Cheers from Australia. Having visited the original Spruce Goose about 4 years ago a question comes to my head. Have you made some scale model beach balls to put in the wing floats ? Certainly a beautiful model.

[@joshuawfinn]

I've seen the beach balls...some crazy stuff in that airframe. Did you pay for the cockpit tour? So cool up there!

[@terrymillard9255]

Oh how things have changed . Last time I was around free flights we were using timed burning rope and snuffer tubes

[@joshuawfinn]

Oh worry not, I still use fuses on most of my outdoor rubber and glow models. :)

[@archivist17]

That's a big boy!

[@MORCOPOLO0817]

Make sure to use acid free carboard when storing models.

[@angelreading5098]

How do we know that card is acid free ? I know that acid destroys the paper in old pulp magazines like 'Flying Aces' does it destroy balsa ? would this be called archival quality card ?

[@larrylutton9616]

The large framed up free flight on the cover photo looks like a Top Banana C or D size?

[@joshuawfinn]

Top Banana 800 with a McCoy 35 on the nose, to be replaced by an OS Max III 35 once trimmed. Really looking forward to flying it!

[@larrylutton9616]

@@joshuawfinn I grew up flying ff with Jay Jackson, the designer of the Top Bananas. Built every model from the 1/2A 300 up to the .35 powered 800. A classic! Brings back a lot of good memories. Good luck with it. Larry Lutton Salt Lake City

[@jamesjacocks6221]

Joshua, what is the Wakefield (or Unlimited) aircraft? Are plans available? I'm looking for a large higher performance rubber plane (which might be RC/rudder) and that looks pretty good. Any comments on the performance? The glide looks good.

[@joshuawfinn]

That's a Dawn Patrol II, designed by Bud Romak. I sell full size plans and a short kit. It flies unbelievably well, best outdoor rubber model I own. It would go great as an RC model.

[@MORCOPOLO0817]

Did you use basswood on the longerons of that big plane?

[@joshuawfinn]

Balsa remains the best choice, with density selected to the task. Strength to weight ratio of bass is not very good.

[@prep0wer]

The mystery of the flying tower crane solved.

[@nickvinci6191]

What are the width and height dimensions of the fuselage at 8:20? And what size balsa is being used for the spars that run the length of the fuselage?

[@joshuawfinn]

The Dawn Patrol fuselage uses hard 1/8" sq longerons and is around 1.5" wide and tall, tapered slightly at the ends.

[@nickvinci6191]

@@joshuawfinn Thank you! What are the motor and propeller specifications used in that model?

[@joshuawfinn]

@@nickvinci6191 I'm running a 26x30 prop on 24 strands of 1/8, 90g. Bud uses a little less pitch and 28 strands. I believe Mike Kirda is using 28 or 30, low pitch, really quick climb.

[@nickvinci6191]

@@joshuawfinn Great, would the flight time be increased by increasing the pin to hook distance and increasing the motor length (using more rubber)?

[@joshuawfinn]

@@nickvinci6191 possibly, but I doubt it. It's a highly optimized design built around a 1:1 motor/airframe ratio. Bud gets 14-15 minutes in dead air at Lost Hills with his.
