Hawker Typhoon (oz5460)
About this Plan
Hawker Typhoon. Rubber scale model. KK 150 series. Scale is 1/18.
Quote: "Hello Steve, I'm sending you a plan which I hope you may see fit to include in your listings. This is the Keil Kraft Hawker Typhoon. It was part of the company's first-ever range of WW2 kits, all made to 1/18th scale and designed by Albert E Hatfull between 1946 and 1950. In the late 1990s Doug McHard launched a campaign in Aeromodeller to try to track down the entire range, but only partially succeeded - maybe we'll have more luck in the Internet age?
Outerzone already has the Fw-190 and Hawker Tempest from the same series, but there are several others unaccounted for, according to Doug's article included in the supplement file. They fly much better than Keil Kraft's more famous, but smaller and later, series of WW2 fighters.
This is a blow-up of the plan as shown in Doug's article, made using the excellent tutorials on Outerzone. There is no printwood for this one, so I made allowance for the inclusion of a scale-width fuselage when sizing the plan for printing. It comes out as 27 inches span if one adds just over 2 inches for the width of the missing fuselage formers (the fuselage was 40 inches wide on the full-size machine) - which is spot-on. I also replaced all the hand-written text on the plan as it was almost illegible ....Regards,"

Update 16/8/2023: Added formers, thanks to Stuart Burling.
Quote: "Hello Steve, Please find attached some formers and ribs for this model. They show some slight mis-shaping in places but nothing that can't be worked around. This is not of my doing - the former sheet provided to me came with free scan distortions (!). These are not the original kit printwood shapes but (I believe) hand drawn formers prepared by Doug McHard. The ribs feature top and bottom spars as in the photos of Doug's model and the leading edge is a simple (thickened) rebated form. The plan, on the other hand, seems to indicate that the Albert E Hatfull ribs had only a lower spar and the leading edge was an 'on edge' strip - personally, I'd go with Doug's version. I've tried to ensure that these formers will fit the OZ plan by measuring former heights with the Irfanview measuring tool. They check out pretty well. Regards, S Burling"

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz5460) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Hawker_Typhoon
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

I shoulden't wonder if you can use Hawker Tempest (oz4436) formers with little adaptations. Pit

It so happens I have the formers and ribs for this plan. Several years ago, I bought a copy of the Keil Kraft Typhoon plan from an online US seller. The plan he sent me is a copy of the original kit plan, with some hand drawn formers attached. I believe these were the ones used by Doug McHard when he made the model in the pictures. I say this because the style of drafting is very similar to the formers he drew up for the FW 190 and Spitfire plans in the same range.
It seems that some of Doug's large collection of vintage UK kit plans ended up in the US after it was sold at auction in 2003. Makes me wonder if the other plans in this series, some of which were obtained by Doug but have not yet reappeared (P-47 Thunderbolt, Zero, P-51 Mustang), are also in the US?
Anyway, I'll try to do a quick scan of the formers and ribs in the next few days.

SB, Thanks very much for taking the time to upload the ribs and formers. My plan is to scratch build this model to a 2/3rds size of this layout. Mainly because my building board is not that large and my storage space is limited. It would also be of interest if at a smaller scale this model would still be a good Flyer considering the reduced Reynolds number.
With regards using the Tempest print wood, I believe the wing planform and fuselage profile are different.

Me too. If we can get a scan of the original printwood for this one, I will most likely end up building one of these, myself.

Word of warning. When reducing the scale size make sure your poster is printed in potrait. I printed my 2/3 scale in landscape and only realised that the fuse was undersized after I'd cut all the formers and longerons...Doh!!

In the earlier post re the Thunderbolt saying it hadn't reappeared did anybody notice that a plan was sold on Ebay recently? Unfortunately I missed out as I was outbid. Did somebody on here get it? if so would they share it?

The Thunderbolt and Mustang would be the holy grail of plans.

Dear Steve and Mary, Just an update on my build of the above plan showing frame test fittings [pics 008, 009], with thanks to you both as well as SB for uploading the formers.
Build details; span reduced to 18 inches, stab area increased by 5%, upped dihedral by extra 1/4 inch and added 2% washout to both wing tips.
All up weight minus covering and paint is 20g. Includes 6 inch Igra prop and two 7-1/2 inch loops of FAI 1/8 rubber. Should be able to get to a reasonable wing loading. That being said I suspect it's not going to easy to trim.
D L L Reid - 24/10/2023
Dear Mary/ Steve, Please find attached my completed edition of the Keil Kraft Hawker Typhoon model reduced in scale to an 18 inch span [pics 010-012]. Of note is that although possessing a smaller wing area than the Tempest of the same series the Typhoon has a much higher tail volume coefficient and thus theoretically should be the better flyer. I omitted the wing cannon. One less thing to be knocked off during trimming. Regards,

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
