Dear IBWALT,

If you are able to share your plan of the balsa pod for the Houston Hawk, I'd love to see it.

I have promised a Wood Hawk to many of you and I will go about that... first...
Why not make your flutter investigation a new thread. I have been studying flutter on built up sailplane wings for over 30 years and still have a lot to learn about designing for flutter avoidance.

Houston Hawk wood fuselage


Jack,

My gratitude as well, for offering to design a wood fuselage for the Houston Hawk. Much obliged. One thing we all discovered, they don't make more time. More demands, yes, time, nope.

We are beginning to get settled. I have much to do between now and the Holidays, but I should be building by just after New Year's Day. I have to deck my attic and get most of the stuff out of the garage into the attic, get the yard started... 1 acre, but the grass is in, mostly... and get the builder to fix all the little stuff so I don't have to... yep, good luck with that...... But I have a Hawk kit and lots of good sheet wood, glue, etc...

Peter nailed it... time is the missing factor...

Jack

I think I have the flutter thingy figured out. None of my Hawks ever fluttered, but my Yardbirds and Journeys have, due to the thinner airfoil, probably. I am going to build another Journey center and use some bias-cut Kevlar on the D-tube. It will not qualify as a woody, but I wasn't worried about that... only the RES thing. We'll see how that goes...

Just as a comparison I have a fuse works fuse and it is 8.7oz without the canopy. Funny thing is I purchased this fuse with the intent to make a mold...

Bringing this thread back to life! I have a short kit coming and am weighing my options for a fuse. I have pm'ed jolly01 about his. Wondering if anyone has done a wood fuse yet as I know Darth too much going on in his life hasn't had the time to finish up his plans as of yet and I was thinking of doing one possibly, but need a little guidance and inspiration. Could go pod and boom, but not a fan of the look and don't think it compliments the sexy wing. Maybe someone has a suitable fuse laying around they want to unload? Just looking for options at this point before I get started.

Thanks.

Take a look at my blog here at RCgroups. I drew up and built several wood fuselages for the Hawk and Yardbird. All the plans are there for download along with a link to the build log thread.

Best,

There have been a number of wood fuselages for the Hawk, including a few threads over the past 1-2 years on RCG. I also built my own pod/boom fuse for a Yardbird. An easy weekend of work. This one has a spinny thing on the front

Nice looking yardbird Dion. Would you mind pointing me to any of the wood fuses builds for the hawk? All my searches seem to come up empty minus the few pod and boom builds, just not my thing for this plane. Wingloda has a nice looking plan set in his blog that I may have printed out to look at. Jolly01 also has a very resonable deal for his molded fuse too, just not sure what I want to do yet. Thanks.

A Durex fuselage would look good with a set of HH wings on it. 100% wood so you could easily modify the shoulder for the new airfoil.

Isn't the Durex slick enough? not to say a set of HH wings would look good... just saying...

Hi Kurt,

Don't get me wrong, I really like the Durex. I think it would look good with any set of wings on it. Mr. Kite is in the process of building one right now and I am hopeful that he will bring it to one of our Rochester soaring events this summer. It's a 40 year old design that looks as good today as it did back then. We now return you to other wood fuselage options.

OK Sports Fans... Things are finally looking up and I should be getting my shop area finished this weekend. I have decided to build the WoodHawk fuselage and then draw it... sounds nuts to some I know... but that's the way my creative gears turn, sometime... I'll start a new thread called the WoodHawk when I get it done, and post lotsa pics and narrative in a short period of time... and probably a .pdf file that I can send out. I have decided to do it in a taco shell arrangement and, while some may disagree, I think it's the way to go... I think you'll all like the articulated, removable horizontal tails...
