So the FAC NoCal bug has definitely come to Northern Kentucky.  After returning home from the Cloudbuster's contest last month in Pontiac, I went right to work.  On the 4 hour drive, I was thinking (2) models which are my WW2 favorites.  The Hawker Typhoon and Tempest.

Who can resist that huge radiator chin scoop that only a mother would love, a set of flat 12's in parallel, and enough fire power to level a town. 

I have lots of references for these so I went right to work.  I started with the Tempest.  When scaled to 16in span, it has 50 sq in and room for a 9in motor tube.  I use DraftSite Professional to design the model, detail the plans, and also the artwork for the tissue.  I find DraftSite to be quite easy to use.

I decided to use heavier balsa this time versus the Dauntless Build as I had to add so much ballast to the Dauntless and it was a bit fragile.  I had some 8lb 0.070" balsa stripped to 0.070" x 0.060" and 7lb stiff 1/32" which I stripped to 0.070" wide for the wet formed curves.  I 3D printed forms to wrap the wet balsa (2) laminate 1/32" around.  I used a glue stick on the inside of (1) laminate piece to join the lamination together which worked great.

Pictures attached.

After completing the design of the Tempest, I started the Typhoon.  Design was very straightforward.  The Typhoon had a longer wing which led to a slightly shorter fuselage when scaled to 16in span.  The Typhoon also had less wing area at 47 sq in.  I added more camber to the Typhoon to handle the higher wing loading with the 6.2g minimum weight required by the Cloudbuster's WW2 mass launch rules. 

9" motor tube fit just in front of the stab.  I used the same balsa on the Typhoon as I did for the Tempest.  I also 3D printed the forms for the laminated parts.  This process really made the build go fast.  I also used the glue stick method to join the laminations. 

Typhoon build was straight forward and completed in (2) evenings.  Tissue for both models was printed on an Epson 7710 using Durabrite ink.  I pre-shrink the tissue with water twice ironing in between each shrink.  I use gift wrap tissue as it is cheap, available, and has worked great so far. 

Photos attached.

More pictures of the Typhoon and Tempest. 

I am wet forming 7 x 9 elliptical props for both models in my 3D printed prop press. 

Looking forward to next weeks Cloudbuster's event.

Now you are using glue stick to join the laminations Smiley You are definitely an innovator Archie and inspirational as well - very nice looking models.

Happy building and flying

Thanks for the kind words.  Looking forward to flying these next week.  Have to get building some NoCal carrying boxes.

Had a very successful outing with these (2) Hawkers in Pontiac.  I ended up flying the Typhoon in mass launch because the Tempest got stuck in the rafters twice.  Ughhh!!! I got it down but broke the wing on the 2nd retrieval.  Thanks to George B. for helping me out there.  No big deal as it will come out and be replaced easily. 

The Typhoon really made George sweat.  I wasn't able to best him, but I did make it very interesting.  I have finished the plans and have uploaded them to the Builder plans.  I have also uploaded the tissue.  As soon as I can upload the videos to Youtube, I will share them too.   

I will finish the Tempest and upload it as well.  Both fly really well.  Very stable and easy to trim.  I used a 7" x 9.1" x 1" wide formed prop on it.  I used a 14in loop of 0.093 rubber.  Ran out of winds 50ft up so longer motor is needed.  Will try a 16" and 18" loop next time.  Hook to hook is 8in.  Might also try wider blades with the same pitch to control the climb and increase the duration.  Max flight recorded was 135sec.  Not bad for 1st time out.

Here is the Typhoon prepped and ready for WW2 Mass Launch.  Note that the cannons stayed on even with a midair on launch and a few ceiling strikes. The Typhoon living up to its name as being able to take a beating.

Those are nice plans.   CG location?

Just went downstairs and checked.  Both models with props and no motor balance about 1/2"  back from LE of wing.  More than 50% of the motor is behind the CG so that makes sense.

Both models took about 1.3 grams of nose ballast.  I added locations on the Tempest plans to use bird shot instead of huge lumps of clay.  Bird shot weighs 0.12g a piece.  Makes it look nicer as it hides in the balsa.  Weight of both models was 6.3g Tempest and 6.5g Typhoon without motor.  

If a plastic prop was used, less nose ballast would be required.  I updated the plans to build lighter tail.  Mine used 0.070" x 0.063" all around.  Tail could be built even lighter, but still have to make minimum weight of 6.2g.  Both models were sub 5 grams before props and ballast.

John,

Looking forward to seeing some others build these.  Both fly really well and are easy to build.

Was able to fly the Tempest in a WW2 mass launch yesterday.  I was pleased with how it flew and it fi wished 2nd in the mass launch.  I have attached a video.

Thanks for the kind words Paul.  I have a long way to go to match your successful models, but it was nice to see this one go.  Both Hawkers really fly well.  Very stable and predictable.  They will be at the Indoor Fling in May and hopefully the indoor Nats too.

Thanks John.  It flew off the board but this was rebuilt since last outing as I broke it while trying to get it out of the rafters for the 2nd time.

It was nice to compete with it.  It is my favorite WW2 fighter.  Something special about that chin...
