Hawker Hurrican Mark IIc 1/5 woodkit
 
As the Val and Boomerang are finished in digital, I started on one of my alltime-fave Hawker Hurricane a while ago. This work is 90% finished, both plans & parts, the Hurricane will be built by a german mate & myself somewhere in 2012...after I have finished my val and maidened her.

Some screenshots, planteaser etc. for the Hurricane in no particular order.

I know there are already some hurricane plans available, but not this scale and some are not as scale as I like it.

RE: Hawker Hurrican Mark IIc 1/5 woodkit
 
Any chance for a few more details, for example, wingspan, engine size, weight, etc? Expected cost?

royal_chris 12-11-2011 05:24 AM

RE: Hawker Hurrican Mark IIc 1/5 woodkit
 


Wingspan is 2438mm, length 1968mm</p>

I am aiming for a max of 20lb total weight, engine options is one of the most challenging parts, if you want no holes cut from the cowl. I do not like 2 strokes chainsaw sound, so I am considering large laser twins, or single gas 4 strokes about 60-80ccm. Still to decide.</p>

Very nice! can't wait to see more.

What CAD program are you using?

I am using TurboCAD for most of the work (plans and 2D work, 3D renderings), not the actual edition.</p>

Finished the first set of fuse plans (will be plotted in b/w) last night. Just a bill of materials and some building notes to add.</p>

I would like to offer my Hurricane 1/5th scale prototype kits this autumn for those hurricane lovers out there. Thought this was a good moment to ask who is seriously interested in building a Hurricane this season.

There's also a new german partner who is willed to prepare custom gear sets for my plans.


This is the current state:


http://ck-scaledesigns.com/uploads/h.../hurricane.jpg


As stated it is the Hawker Hurricane Mark IIc
Features are


- 1/5th scale
- a three-piece-wing with the center permanently attached to the fuse - original Clark YH airfoil
- canopy rail notches for 1/4" prepared
- maintenance doors prepared
- wooden wing servo mounts included
- control horns milled, elevator and inner flaps connectors milled


As usual, my kit come along with:


- multiple sheets 1:1 colored plansets, printed from original files, no photocopies (no scratchbuilding possible) - metric and inch measurements!
- all wood pieces needed to build the plane lasercut or cnc milled; except sheeting and strip wood
- hinging and control horns cnc milled
- cnc milled (bullet proof) firewall, gear and wing mouting, no compromises here
- quality a/a+ wood from Germany's best balsa and plywood supplier
- fast reply and feedback directly from myself on questions during built, possible issues - revisions where needed
- solid packaging w/ shipping ensurance worldwide


In addition to that, there will be a clear canopy, fiberglass cowl and gear set prepared to be sent in 2015.
This built will take serious time, it is a rather complex plane, as you know.


My aim was to draw the most scale appearing Hurricane as a wood kit available. A quarterscale might follow after these building and maiden experiences.


Please send me a note with your adress/contact email for quotes, feedback and questions. The prototpe kits will come as special offers only once and a limited qty. There will be no scratchbuilding plansets offered and no cad files sent. Thanks for understanding, this was some 2 years work I have to protect. I will join in as soon as my workbench is empty. http://www.rcscalebuilder.com/forum/smileys/smiley1.gif




Thanks
Christopher


PS the follow up project 2015 will be british too ;)


Scale Specialties 09-05-2014 10:13 PM

Looks fabulous Christopher!!!! Any chance you would offer this at 1/6 scale as well. The 80" size would be ideal for some of us.
Thanks, Dave

royal_chris 09-06-2014 01:07 AM

Hi Dave,

thanks alot for your words. Unfortunately there will be no 1/6th scale from my side, but probably a quarterscale later next year. Some people have already asked me about that and there's no proper kit available.

You might probably go for the Brian Taylor Hurricane, that is about your scale?
Best, Christopher

royal_chris 11-23-2014 03:19 AM

Hi guys,

I have to post a big SORRY. I had several messages without being notified about them. Some settings we not set correct. Haven't been here for a while, so I wanted to say Hi again, the 1/5th scale is available.

The fiberglass accessories and canopy will be prepared in 2015.

To avoid delays of answering your mails again, please use the email provided in my profile here.

Thanks a lot!
Christopher

I have been working on the 1/5th and 1/4th moulds for cowlings and canopies.


The progress over a couple of weeks:


I have the formers and side pieces lasercut. The side pieces help to sand the perfect contour:
http://www.ck-scaledesigns.com/uploa...ling_rough.jpg


The wood was glued to XPS, which is a harder version of styrofoam in Germany, nice to both saw and sand. Keeo your vacuum cleaer pretty close to you when working with these.
http://www.ck-scaledesigns.com/uploa...e/cowling1.jpg


Roughly sanded to shape. There's a typical shape error for a lot of hurricane kits: the bottom front shape tapers negatively, a lot of fiberglass cowling on the market are wrong at this particular point. It influences the appearance of the Hurricane a lot. The negative curve leads to a lot mre sportive appearance.:
http://www.ck-scaledesigns.com/uploa...e/cowling2.jpg


First coats of dispersion putty and again sanding:
http://www.ck-scaledesigns.com/uploa..._spachtelt.jpg


2 x 160 g glass cloths for a strong surface to work on:
http://www.ck-scaledesigns.com/uploa...ng_glassed.jpg


sanding, filling, sanding....end in sight. Detaillings of the cowlings starts soon and I am not really sure how far I should take this. It is a lot of extra work and customers are not always willed to pay for this and compare it to flat fiberglass cowlings with not extras at all:
http://www.ck-scaledesigns.com/uploa...e/cowling4.jpg


Best,
Christopher

yoska 12-03-2016 06:28 AM

Any news on the Hurrican>

royal_chris 12-04-2016 05:13 AM

Hi Yoska,
currently not. I moved through Germany with new job, appartment und really nice workshop. Will continue working on detailling the moulds soon. The protoype built of the 1/5th scale hasn't began yet.
Christopher

royal_chris 02-23-2021 11:54 AM

I finally took my cnc last autumn into service and produced two prototypes of the hurricanes. If somebody wants to join a testbuilt, please pn me.

Just out of curiosity:
  • do you have an APPROXIMATE price for your kit figured out yet?
  • would you consider selling templates and the molded parts along with plans for those like me that would have a hard time getting metric sized materials?
In my case, I have tools to make the wood parts and I figure it would be easier to ship paper templates and plans than precut wood. Your thoughts on this?

When I started to design kits, I decided to not include templates or sheets with all pieces shown. First because of copyright issues and I don't want other people to produce and sell my kits. It was years of work. Secondly my kits contain 300 500 pieces, I wouldn't want to cut with any saw. That's why I don't like to call them "short kits", it is not comparable to usual short kits with all the extras that are standard in my case (hinges, control horns, servo mountings etc.)

The regular price will be 600 euro for woodkit and colored planset, prototype builders are granted with a 10% discount. A metric to imperial conversion table is included, 99% of my clients are Americans there's no problem in using 3/32 instead of 2.5 mm, or to cut stringers from appropriate Balsa sheets yourself.


Thanks,
Christopher

Hydro Junkie 02-23-2021 05:58 PM

;And I totally understand what you're saying, considering how many plan sets are being sold by second and third parties through the internet. As far as I'm concerned, it's all good. Unfortunately, it will be a while before I can get that much spare cash but, with that said, I still want one........eventually :)

royal_chris 02-24-2021 01:26 AM

I will post updates on the the testbuilt, mould creations and so on. You can easily join in later, since I produce the kits myself on my own cnc. Thanks for understanding my decision to not offer scratchbuilding and respect for my work.

I started checking the fitting of my kits. No glue here, just took the pieces out of the sheets to see, if everything comes together nicely, which it does.

Today I checked the fuselage, if all stringers run straight to the rear. This part took me countless hours when designing in digital. I wanted it as close to the original as possible. All stringer are quantity wise and angle wise scale.
They are cut from 2,5 mm balsa which seems to fit optically also nice. The stringers on 6 and 12 o'clock are included to the kit and have notches for all formers. This helps setting up all formers alot.

Marriage
 
Meanwhile the front and rear fuselage married to the full size. Since the fuselage has a solid stand on its firewall, I also took a picture from underneath. You can clearly see the center flaps fuselage plate.Everything is glued now except the ribs. I will first adjust the wing joiner and u/c mounting.
Next stop will be rudder and elevator stab.
​​​Christopher PS have a nice eastern.

Elevator
 
Elevator in the making, it's all Balsa wood. All pieces including trailing edge are included to the kit. No need to cut Balsa filling blocks in between the ribs. All pieces intersect, self adjusting 90.

The hinges are delivered as all control horns, rudder connectors etc. The material is 3mm phenol resin, which has a very glossy surface, so I sand the bonding areas with medium grid 100. They are glued with thickened epoxy to their ribs, the trailing edge has slots to stick them through while finishing the stabilizer. Partial sheeting is the final step.

royal_chris 04-07-2021 10:44 AM

Before glueing the hinges, I usually enlarge the center hole and put some brass guiding in there. Along with the 2mm steel wire, the axis has zero play then.
Afterwards I use thick epoxy to glue them while the axis is always inserted to avoid twist and surprisings after everything has hardened.

The elevator control unit looks like this, all parts are delivered with the kit:


https://cimg8.ibsrv.net/gimg/www.rcu...b6e8ba6617.jpg

Meanwhile I started working on the elevator rudder. The torsion wire is usually stick into place, when parts are glued.

royal_chris 04-15-2021 05:50 AM

Upside done apart from sanding the le which I start when the bottom side is sheeted as well. Since the elevator is done with a rather thick symmetrical Naca 00xx airfoil, you might select the better looking side for the top one 😁

https://cimg7.ibsrv.net/gimg/www.rcu...2178207d9e.jpg

royal_chris 04-20-2021 09:38 AM

Currently sanding all LR to shape, I wanted a little motivation and put the stabilizer onto his Balsa saddle (which fitted pretty fine without sanding!)
Tail starts to take shape.

u/c mounting plate milled from 6 mm air-ply, supported by two poplar ribs with 1,5 mm air-ply doubler. A few spots shouldn't care about ultralight weight for safety reasons. This type of gear mounting is standard for my kits, bulletproof. The outer whole is for the outer wing mounting later. Adding the holes for the mechanics and will epoxy the plates to the ribs.

royal_chris 05-02-2021 03:08 AM

Just a few minutes of parts preparing the parts and a bit of white glue, the rudder stab is set up.

Self adjusting, you don't even need a plan underneath. Woodbuilding can be fast, if the designer did his homework.

The 6 mm Balsa trailing edge is also the last fuselage former, this helps to build a solid leightweight rudder.

https://cimg2.ibsrv.net/gimg/www.rcu...662878f93c.jpg

royal_chris 05-04-2021 12:35 AM

In short time, the rudder is completely setup. Controls and hinge axis are similar to the elevator... And they fit together nicely. Next step will be partial sheeting of the rudder stab and sanding all pieces to be fabric covered later.

Started with the inner flaps plate. The outer flap ribs are part of the wing ribs with a small holding tab to give the proper shape to the inner flaps plate. All remaining ribs are inserted with the guiding for the flaps wire axis.


I took the weight before this step. Fuselage is 3,8 lb so far, that's nice.
