Sorry for the very poor level of updates on this blog.. It is my downfall not keeping this updated.

I will at some point fill in on the missing parts since the last update in March but for now I just wanted to share the following news..

Its Finished!

Yes.. after almost 2.5 years of actual building (on & off) it is finished and ready to fly..
I took it with me last weekend to the Lleyn Peninsular however the wind gods didn't play ball so the maiden will have to wait for a blow on the favourred WSW slope on the Gt Orme.

Here is a pic taken on Saturday by Phil Cooke.

Final Specs....

Wingspan 1.92m (6' 3½"
AUW 4.5kg (9.92lbs)

Now whats next???

Great progress Dave, looks brilliant. Tail fin is the size of most PSS wings !!



Cheers Ade. Yeah, the fin is a fair size... id say its a smidge smaller than one side of an A4 wing.

Similar to the B52 size ones from the Simon Cocker plan.

Great progress Dave, well done. Nice detail in cockpit.

What scheme are you following?

Good luck with the glassing.

Having one of the smaller ones, I can see that you have gone for a formed top to the wing rather than solid block as per mine which is a great idea as it will save weight.

Are you doing the Andy Blackburn original plan enlarged area wing or the cut down more scale wing which Phil did? I would favour the former as it will perform better in light winds.

So we will see it at the Orme in April? yeswink

Thanks Peter.

Not decided on a scheme yet... Will need to look soon though. The 3d printed cockpit parts I designed and printed myself. something else I have been slowly learning to do!

I have glassed he fin and elevators so far and hey have turned out okay so fingers crossed it continues on the res of the model.. I'm new to this glassing lark!

Originally the spine was a block one but that slipped whilst the glue was drying so had to be removed. I then decided to do the frame version and as you say, it saves a few grams.

The wing... apart from the version change from the plan F variety to the GR version, I have decided to keep everything as per the plan. I hear the scale wing needed a bit more of a blow being smaller so the plan wing is being used. These were made to a fantastic standard by the chaps at Cloud Models at a very reasonable price.

Unfortunately I wont be at the April meet now. Due to the madness that is Covid19 and my line of work, we are under instruction to minimise risk to ourselves so non essential trips away are culled for now!

Obviously I will be assessing each meet in turn on how things are moving along.

That looks good, gives that its flying standing still feeling.thumbs up

Nice to see some one's workshop looks normal (used not pristine)

Thanks Alan. Yep. It does look quite fast even sat still.. Something about jet fighter lines!

The workshop is only a mess as I have other stuff in there over winter. its not normally that bad!

How can it be almost a year since my last update?

Well to be honest, quite easily!

I lost my build mojo last year and then before I knew it it was time for our 2019 Isle of White Caravan Holiday followed by Christmas and another holiday to Turkey in January this year... SO time has literally flown past!

Anyway, I have been back at the Tornado in fits and starts and it has moved along considerably.

My original plan was to not glass the model..... Yeah yeah... That's changed and it is going to be glassed! This decision was pushed along with the demise of the Solar company meaning Film and Text became rarer and more expensive.. So glass and spraying it will be!

Pilots and seats were printed and purchased form fellow PSS member Andy Meade. (I now have my own 3D Printer, courtesy of SWMBO)

You will be able to see how things have progressed in the series of pictures below with the last two being taken just an hour ago!

I promise to try and update again soon!

So is it finished yet Peter?

I have started gluing sheets together for the wing skins.

Not going to bother with a blog for mine as I always forget to take pics and update them.

No one jumped on any colour schemes yet? I'm still fairly undecided.

Not yet. I think though we should all copy Phil's and go orange! At least they are visible in the "Sea Mist" so you don't need to land!

Following for guidance!

My extra wood arrives tomorrow so hope to get building soon.

They look great Ade.

Cant wait to sit one on top of the model soon.

I will update the blog soon as things have moved on quite a bit since the last update.

Just logged in for first visit of the year and been hit with this terribly sad news.

My thoughts and condolences to Dave's family and friends.

I got to know Dave initially like many through this amazing forum in his role as Admin, offering some of his apparently limitless knowledge and guidance to us mere mortals.

I also read his articles in the magazine and despite my then much lesser knowledge, I was able to understand them fully. Dave had a way of writing things so that anyone could understand them, even if you didn't know all the technical jargon!

It was in 2010 that I conversed with Dave as we drew up plans and launched the 2011 Webbit Mass Build. Little did we know then the Mass Build would not only continue annually, but would spread also into other disciplines such as the PSS Glider Guiders!

I only met Dave in person a handful of times, at Steve Webbs in Frodsham and at Greenacres, but a lasting impression was made of such a kind hearted and gentle soul.

I am sure everyone would agree that the world of RCM&E and model flying in general has lost one of its great contributors.

I shall raise my glass to you Dave.

Fly High In Heaven.

Save a space in the pits for us all!

Another week gone and time for another update...

Well, It seems the build bug is firmly in control at the moment with things coming together!

I am pleased to say also that the 2nd Tornado (being built by Warren) is finally underway. I'm not sure if Warren is planning on doing a build blog or not though!

Anyway, where were we....... Oh yes..!

So the rear top decking has gone on over the rear top stringers and the control rod is connected to the AMT axle.

The 2nd air intake is under construction also so these parts will be ready to be added later in the build!

I'm not going to bore you with pics of those bits though as there is much more interesting stuff to update!

Yesterday the doorbell rang.... There was a delivery in the form of a large cardboard box!


That's right. The wings arrived from cloud models!


So 2 sets of wings (one for me and one for Warren).

A quick inspection showed the quality and finish of these to be at a very high standard.

I just had to lay a set out to see!


But that just led to the obvious thing happening.... A full mock up!


Oooooooohhh Yeaaaaah!!!!

Now we really are getting somewhere! You will see the rear deck in the above picture also!

Okay. So, These wings are not swing wings and will be joined permanently in the fully forward position, but I just couldn't help seeing what it would look like if the were swept back!

What do you think!!?


Pretty cool.... Maybe a future model will have swing wings.. Who knows!

So to the wings then. Considering they only arrived yesterday, the following has been completed:

Servo position calculated.. I plan to have the wing fuel tanks on this so the position of these pylons had to be calculated to the scale and the servo positioned outboard of these!
Once this was worked out and the positions transferred on to the undersides of the wings, these were cut out!


I hadn't asked for Cloud Models to do this for me as I wasn't sure exactly where I wanted them so needless to say, there were no servo wire holes either, so these also have been done with some heated wire pushed carefully through at the required place so the exited into the servo bays!


Again, other measurements had to be calculated so as not to route them where the wing joining braces would be placed!

The positions of the joining braces were then drawn onto the wings and cut out on the fretsaw with each wing half supported in their foam halves (if that makes sense!)

The braces are made from 8mm ply so will provide a good solid link!

That was all yesterday..

So today, The leading edges and false Trailing Edges were glued on and once dry the sanding down has started to ensure nice smooth transitions. (This is nearly finished but had to make tea and walk the dogs!)

So just one last pic showing the wings together with the braces in position. (These will be sanded down flush once the wings are joined for good!)


So that's it for now!

I will be doing more sanding tomorrow as long as the weather allows, as there is nothing worse than sanding in the workshop with no moving air and balsa dust filling the air (and lungs)!

As always, comments and questions are very welcome!

Sounds great Ade, I have faith in your ability.... Sure it will fit the model just fine!

Thanks Tim. Yes, Shes quite a good size.. To be honest, I'm glad I didn't go to 200% plan. Would have struggled to build and then store!

Looking forward to the wings arriving and then I can get a real size feel for her!

Will update when there is more to show!

01/11/2018 16:04:52

Neither Andy.

Will be looking to inlay spars myself, just like the A4 build.

01/11/2018 15:52:03

Small update time...

Inbetween work and a family long weekend away visiting sick relative, I have managed to do a little more on the build!

The axle for the AMT has also been made up and a metal horn spot welded to the axle. This will allow the clevis to link up solidly as this whole area in time will be sealed up!

Unlike the original plan, I have decided to move the AMT Servo into the rear part of he central under-wing bay in case any issues and it was to need replacing in the future!

From here, the rear sides where checked for fit and then fitted along with the rear formers and the AMT axle.

Unfortunately I forgot to take any pics of this stage!

3 wide stringers lay into the rear formers from F6 to F8. This provides the stability and stiffness to the rear end and as such has to be glued in whilst keeping the whole airframe centralised and steady. As the plans are being used for a 2nd build, I was unable to do this over them, so some accurate guide lines were drawn on to the build bench and the model pinned down to it!

Once this was all set and the rear end stable, the model could be removed again from the build board without risk of any misalignments later on.

I couldn't resist a mock up!


Definitely a Tornado shape there now!

The cockpit area has been lined all around and F4 (which provides the spread out of the rear sides up to the air intakes.


So what else...

I decided to work on getting the intakes sorted (well one of them for now!)

These are made up of black foam, veneered in balsa!


And this is how it should look on the model!


So that's about it for now...

Oh, I have ordered my wings from Cloud Models and they should be here in the next few weeks!

Wings will be as plan, no alterations to size or profile.

The only planned change on these will be to have a servo mounted in each wing with direct link to each aileron instead of a centrally mounted single servo running torque rods.

Will update again where there is more to tell!

Wow surprise

Didn't expect that!

Wonder if adverts will now include the word "rare"!!

At least you can still download v5.5 however without the lead to connect to Tx, its no good!

Thanks Mark

Going to leave it with Ade for now and if needs be will look at making one myself! ( I have faith in Ade's abilities! )

Looks good.

I measure mine at 416mm. Would suggest extending rear end by 3mm... Can always reduce to fit then!
