I will have a minimum of 3 Superhawk G1's available this Spring.

I will post availability as all of you well know I take no money for what I cannot ship when paid for.
Oh yeah, I take no names for a list. Nobody answers to lists. Ask me how I know!

I will redeposit the proceeds of the sales into my fund for making 3D printed parts for the Hawk
and Superhawk. It is INCREDIBLY expensive and time consuming for this endevour but well worth it!

A while back I had a conversation with Bob Martin and he told me that when he was making the original Hobie Hawk occasionally when drilling out the wing roots that the drill bit would load up with swarf and blow out the plywood on the wing panel. He had enough of these that he would cut off the roots and make 6 foot wings out of them. He never sold them but rather gave them to guys in the shop to use. He said the plane flew great. Like it was on rails.

That reminded me of the original plane I built that used curved wings that were 6 footers. That was the first prototype for the Superhawk I made back in the early 1990's. It was called a mini-hawk. I flew that one until I had a bad landing and made the 8 foot wings for it. I missed that 6 footer because it flew great on the slope.

Well I am now working on making that Mini Hawk again using what I have learned from lots of building over the years and today I finished the router jig and made my first set of wings for this new plane. Pictures are below.

I took a picture of this set of wings with an original Hobie set of 2 meter prototype wings I picked up with Brian Joder of Hobiehawk.com years ago. Hobie Alter saw these wings and said they never made it into production as he sold the tooling before that could happen. Very rare wings...

My wings are 36" per panel and Hobie's were 39" (1 meter) each panel. Mine are a bit shorter but I will be flying this on the slope so I wanted speed anyway! Hobie had his proprietary under camber airfoil on his and I used an RG-15 airfoil. This thing will be killer on the slope!

Anyway here are a few pictures:

After a couple of confused e-mails that RIT Dye is not taking to the CAB canopies I had to do some digging.

It turns out that RIT has reformulated the dye compound because of availability of ingredients in the dye. This was started in 2011. They slowly implemented the change to their formula over the last few years so that all their newer dyes will NOT dye the canopies made from CAB plastic.

The good news is that they are just now starting to make a new dye marketed under the RIT name as "Dye More". This is specifically made for plastics and synthetics. The bad news is that it is so new hardly anyone has it.

Here is the link:

https://www.ritstudio.com/techniques...asics/dyemore/

Initial tests of this new dye indicate it needs to be heated for better penetration of the plastic. Curt White says the canopy needs to be immersed immediately so steam from the solution does not form on the canopy before immersion. Speculation suggests that the steam penetrates the plastic surface and keeps the dye from entering the plastic causing an uneven dye job.


Another company makes a product called "iDye Poly" that works. They make several colors and I found mine at Hobby Lobby and Jo Anne fabrics. It may be at other locations as well. I will post a picture at the bottom so you can see what the package looks like.

UPDATE:

February 2017

I am currently working on 3D printing some parts (mainly the dorsal assembly) as the printers are now able to extrude polycarbonate which is structurally superior to PLA or ABS being used in earlier models. If it works out I can sell them as spares for Hawk owners. I should have more info in the coming weeks ahead.




[SIZE="3"]I have recently completed work on tooling that allows the reproduction of stabilizers and rudders for the Hobie Hawk. This has been a long tedious process but the parts are drop in replacements for the factory original pieces.

Just FYI, The original Hawk tooling changed hands a few different times and as a result the alignment and drilling of the stabilizers (along with the dorsal fin) varied as much a a politicians promises before election day. In other words, there was and is no consistency to the alignment.

The stabilizers I make are drilled in a machined tooling that is aligned in all axis. When you fit them to your Hawk, if they are not aligned across with the wing, that's because of the Factory set up of the dorsal alignment jig. Not to fret! If the misalignment is minor, you can CAREFULLY use a heat gun to heat the dorsal just enough so it will bend. DO NOT HEAT THE FIBERGLASS TAIL CONE! It will soften and fail! You may need to mount the stabs for leverage holding the twist in while the plastic cools. It doesn't take much so don't over do it! Do not heat the stabs either!

OK, the plane will...Continue Reading

I was recently diggin' through my old plane stuff and found this build video from Birdworks by Steve Hendirks that shows step by step how to build his RC Gull semi Kit. This kit is no longer in production but if you have one sitting in your closet this might help you to build it as intended by the designer. Enjoy!

Completed build notices sent out today 04-25-2015.

Please check your personal email account for an attached PDF file regarding the completion of the build. Planes are now ready to ship.



Oh boy!

Here we go again with another build!

10/08 - Cut core blanks from foam and started hot-wire cutting all of it. Its gonna take awhile to cut it all. It seems like an endless mountain of foam! Kinda like eating an elephant I guess...

Picked up the plywood yesterday as well. Amazing how the Finn's get that birch plywood in 3 layers down to .4mm thick! Well, they charge enough for it anyway...

10/18 - All wings and tails are now hotwired and completed. I have a HUGE stack of blanks on the shop table. Had to build a new storage rack for the Finland Birch plywood as the old way wasn't going to be practical anymore. Space issues. Started cutting fiberglass and Kevlar for the fuselages. Pulled the older "Replihawk" tooling out (Hobie Hawk clone) to prep for the Minihawk build. I some of you ordered original Hawk tail peices. Stabs not a problem but the rudder foam jig needs to be rebuilt. The old one is too messed up from being in storage.

11/07 - Wing cores are all joined and cut all composite cloth for the fuselages. Lamination in progress on all fuselages for the next couple weeks. Cutting cloth blanks for dorsal assemblies and prepping molds. Machining new templates for traditional hawk rudder cores repairing damage from storage.

11/20 - Main...Continue Reading

Deposits are in, the build is on!


Today 9/24 There is enough serious interest I am going ahead with the build. By early next week I will pick up the plywood and foam on my way home from work to build the planes I have deposits for. Started pulling the jigs and molds out today and had about 1/16" of dust on them. Been awhile I guess! I will also be working on the Minihawk (two meter) during this build and will post pictures here of that as well. Standby you guys, you will get the best Superhawk ever built when all is said and done.

Hobby King Servoless spoilers needed for your plane:

***NOTE***

The Hobbyking spoilers have been reported as unreliable and are rather difficult to remove for servicing. Therefore the build of G1's will now have TWO spoiler bays per panel for use with conventional servos such as the HS-55's (Hitec) or equivelent.

Here are some documents that came with factory finished Hobie Hawks that had the RS Systems Single Stick Orange Box transmitter.

This was a very small (The RS company meant "Really Small" BTW...) single stick transmitter with a bright orange housing designed by Bob Novak back in the mid 1970's. By todays standards they are now obsolete wide-band AM equipment in urban areas especially. The FCC has outright banned the use of wide band transmitters for several years now so don't attempt to fly any vintage hawk with this radio. You could interfere with someone elses narrowband equipment, but worse yet the old AM receiver isn't built for today's RF environment. Bad JuJu all around.

This was a e-note sent to Brian Joder at Hobie Hawk dot com. He sent it to me and I just don't know who authored it otherwise I would post that as well.

Good times!

Here is a pair of 6 foot wing panels that I picked up from a guy in California several years back. I am unsure of their origin and showed them to Hobie Alter himself and he said they were definitely made on the factory tooling. He also said that they were doing alot of experiments with the tooling and that these could very possibly have been prototypes or experimentals for shorter wings. He said no six foot wings ever made it to market though as the production ceased after only a couple of years.

When Hobie Alter and myself went to fly in the past he saw these wings. He said that these were factory produced wings but he had no idea how they reached the open market. He then went into a memorable event on how some Hawks went out the backdoor by a very likeable employee he wished had not happened. A girl had sold many hawks from the loading dock that he very much liked. He was seriously dissapointed and betrayed... For whatever reason she got involved in trading his sailplane for "desireable assets" . Guess times don't really change thoughout the years.

Talking to Bob Martin about these as well he said that during his stint with the Hawk tooling they had a few rejected 4 foot wing panels come out from the wingrod drilling stage before the rib bays were routed out. He said that occasionaly the drill bit would "blow out" the thin plywood surrounding the hole because the drill loaded up with swarf (chips). They would cut off the bad part at the root...Continue Reading

Here is an original set of info sheets sent to me by the Hobie Model Company way back in 1976. These prices are almost 40 years ago so imagine in today's $$ what it would be! FYI the Historical US CPI data calculates these prices should be multiplied by 4.33 to get what it would be in today's dollars.

That means a $399 Hobie Hawk with radio finished would be $1727 today.
The sheets below say there was a clearance sale on radio ready finished airplanes at $299 that's $1294 today.

A kit was $109.99 which is $476.25 today.

A CAB RIT dyable canopy was $5.28 and is $22.86 in today's dollars.

Notice they sent me two price lists. From January 1976 to March 1976 the price of a canopy (and some other items) went from $2.40 to $5.28. a whopping 220% increase!

Enjoy!

Here's a chronological documentation outlining the construction process on 12 Superhawks. Also attached is the PDF build manual for the original Superhawks that are featured here as well as the Superhawk G3 build sheet. It took about 4 months to do this build and yes, it was A LOT of work! Enjoy!

Been working on this for awhile. I needed to make a true to scale original tailpost and dorsal assembly for the Superhawk but needed it to have the capability of accepting larger joiner rods for a beefed up stabilizer assembly so over the last year I have been working on molds that can accurately replicate the injected molded parts of the original plane. Anyone that has a Hobie Hawk knows how rare and scarce original dorsals are because they are no longer made. Building the molds was a new process for me and involved alot of experimentation and trials but the work paid off and I can now replicate the tail assembly out of composite materials.

The dorsal is a double sided molding laminated from fiberglass cloth, S glass tow and carbon tow. Much stronger than the plastic dorsals on the Hobie hawk but then again I can't injection mold them several hundred per hour either!

It took one day to make the tailpost and two dorsal halves and another day to fabricate the bellcrank and mill the slots and holes. Very time consuming but the parts work. Yipee! A total of eight seperate molds and five pins are required to make one dorsal.

It's been awhile since I built anything like this and There are enough advancements with radio gear, materials, and control technology to make this project work. The goal will be to make a full scale Bald Eagle from composites utilizing the build experiences of myself and others to make this thing look as real as it can get. My only fear is that where I fly there are LOTS of real Bald Eagles (Skagit River, Washington) and what will they do when encountering this thing? The talons of a Bald Eagle are 6 inches from front to back. When they close, they are like a pitbull's jaws. Good luck dislodging them...Only one way to find out I guess...


Started on the drawings for the prototype. Gave Compufoil a good workout yesterday. Sure beats hand drawing all those airfoils!

Ordered some true scale Bald Eagle eyes from a taxidermy shop that are correct for the bird. Woodcarvers use them and its a good thing they did the research on the eyes. They are not yellow. They are off white and have a dark band around the outside. I figure the face has to be accurate. I don't want this thing coming out looking like a chinese parrot-like knockoff.

The last Bald Eagle I built was years ago when I was still in high school. It was about the same size as this one but had a rudder. Bob Hoey has since then blazed a trail for RC birds since then and also a Japanese gentleman has done a great deal of research on how real birds fly. This build is based on my work, and these folks work as well....Continue Reading
