Great Video Geoff, Thanks for posting.

Nah Ali,

He's thinking 'Oh ****, That maneuver was pretty crap and all these modellers are going to have to copy it now!'

Hello David

Yes, it's me. I had quite a number of back-seat Hawk rides myself whilst at Chiv, with a little stick-time of course and boy what a thoroughbred that plane is [8D]. I still live only a couple of miles from the airfield and our club can fly there any time which is nice. I'm resolved that one day I'll be flying a turbine-powered Hawk from there and re-living old memories of watching Ian Wood, the then RAF solo display pilot, practising his display routine a couple of times several mornings each week just as we were all arriving at work. I have a VHS tape of his routine - must push it through my camcorder into the PC and make a .wmv

The Airworld video is most impressive, the Hawk handling beautifully with the lightness and grace of a ballet dancer, so I think that all you builders here are set for some really good flying.

Regarding JP aerobatics, one of just two memories I retain from when I did my eng course at Cranwell was watching one performing a really neat manoeuvre which was a cross between a wing over and stall turn. He'd pull up to vertical, then just before the plane slowed too much, would rudder it over into a 45 degree knife-edge climb, and then 1/2-roll onto the opposite knife edge. The plane would continue upwards for a short distance, and then stall turn back to the vertical downline, and then pull to exit at the entry height. It always looked to be a nice exercise in timing, and was a surprisingly slow and graceful manoeuvre.

The other memorable incident was Haydon Baillie giving the airfield a thorough beat-up with his Sea Fury [8D]

Good luck with your Hawks!

Best regards

Gordon

Hi Guys

Received my secondary flap vanes set from Henry
Fitted them in a day without needing to modify anything structuraly
A very well thought out and yet very neat and simple design(well done Henry)
For those whom were debating getting this set from Henry it comes highly recomended

Cheers

Francois

Hi all

A friend of mine has just received a AW Bae Hawk kit and he wants to finish it in the T-45 GosHawk scheme.

Anyone knows the FS color codes for the white, fire orange and mat black?

Thanks in advance.

Here some picture of the canopy I did to give it that TOUCH

BTW Als your hawk will be ship out to you NEXT year MAYbe I hope you have something for me to do when I get up there in the UK.

Good to see you on the internet, Gordon and thanks for the good wishes.

Getting there, everythings red, except the white bits. Any progress out there?
Regards,

David Gladwin.

Looking good David.

On another matter, I am getting close to flying mine(in primer) and am setting it up. Part of this is juggling the equipment to get the CG right. According to the info I was sent the CG is 20mm in front the 35mm wing tube. My question is really aimed at Henry/Ali as they have built/flown a Hawk, did you set the CG at this point? If so did you find it OK ie was it twitchy or soggy or about right?

Thanks in advance.

Geoff.

Hi Geoff.
Perhaps you should ask your Air world representative to share his flying experiences with you Sorry couldn't resist that one!
I flew mine first off at the Airworld settings. it flew great but was a little nose heavy.
The best test for the correct CG is Knife edge (Sounds strange I know) But with the correct CG the hawk will not pitch in knife edge. Too nose heavy and it pitches to wards it's roof. I also found it heavy to flare on landing. All I did was move my ECU pack (AMT Pegasus) from in front of the nose wheel bulkhead back to the rear section of the canopy area.
Hope that is of help and good luck.

Cheers for that Ali. You made me smile

Hi Gordon W
I think that the JP manoeuvre that you describe is called a reverse stall turn in the RAF - at least that's what my student guide says. The 'noddy stall turn' was also fun - in this the aircraft is pulled to the vertical, yawed left through about 20 deg, yawed right by the same amount, and finally yawed left into a stall turn (and vice-versa). I don't think that the Hawk could do either of these, but someone may prove me wrong?

If making scale flap vanes for the Hawk the rear sub spar has to be moved forward 1/2 inch. the spar is just 1/8th glassed balsa so no big deal structurally. Howver, the upper skin needs suporting as its just not stiff enough otherwise. This is my solution which may help builders thinking of this mod. Small 1/8th ply sub ribs were made for 2 inch spacing. These ribs went through slots cut into the subspar and extended forward by 1 1/2 inches and glued to the top skin (ONLY at this stage. ) Sections of subspar at every alternate sub rib was cut away leaving everything supported by pieces of subspar at every alternate gap. New pieces of subspar were cut from 1/2 inch balse were then glued to the top and bottom skin 9/16th inch ahead of the rear face of the original spar. When the glue had all dried the remaining pieces of original spar were cut away and the gaps left. A new rear spar of 1/16th ply was glued to the new sections of rear spar and the whole thing glued up liberally with Hysol. The result is a very stiff upper skin and original strength more than restored. Quite straightforward apart from being a time consuming pig of a job.......but its done now !

Re Colin's JP stall turn: The noddy was quite easy but needed a little more speed than the standard 90 knots at which rudder was applied for a normal stall turn. After the first nod full rudder would usually bring the nose over with some inertia so the stall turn would just follow. A variation on this was a hesitation stall turn, again needing a little extra speed. Fun to watch students trying this and ( sometimes) watching them recover from the ensuing spin ! The JP had quite alarge rudder , a hangover from its Piston Provost conversion. The Hawk rudder is relatively much smaller but I would be surprised if it could not be stalled turned, after a fashion ! Any Hawk QFIs out there. ?

Regards,

David Gladwin.

Colin and Dave. Thanks for your comments on the manoeuvres and reminding me about the noddy ... I remember seeing JPs doing that manoeuvre now.

Regarding stall turns in the Hawk, the pilot did demo one for me during one of my back-seat trips, but explained that I hadn't to tell anyone about it as the manoeuvre is prohibited in the Hawk. It was a long time ago and he's left the RAF so I guess I'm safe making this admission now. Apparently the side loads on the fin during the manoeuvre could cause structural damage. So the Hawk will stall turn, but one shouldn't do it.

That's a pity as the two manoeuvres just discussed are really good to watch.

Regards,

Gordon

My last Hawk post for a while as I am off to the northern hemsphere for the summer. Hawk #1 painting is almost finished and #2 construction well advanced. Here you see #1 with fuselage rubbed back ready for decals and clear coating but the wings and stab. etc are already finished in high gloss red, no decals so no clear required.

Hope to see some progress on other machines whilst I am away. Hope to get some more Red Arrows photos and also some of all black machines as based at RAF Leeming.

Regards,

David Gladwin.

Guys,

About to type up one of my 'manuals' for the main gear door installation/setup with all measurements you'll need etc to get your doors opening/closing spot on.

It's quite a bit of work - just wanted to see if it was worth doing?? Anyone want it? [&:]

Cheers,
Mark

OK,

Here it is. This should HOPEFULLY help you guys work through this #&%£"(& @*&^£ part of the build!!!

Let me know if you need anymore info, if I have missed anything or if you want me to carry on with these 'guides'

Looks good Mark, now for the hard bits, the secondary doors, particularly the small outboard door !

Regards, David Gladwin.

Yes, yes I know Looking at those today hopefully [&:]

Does this pic give anyone an idea for the outboard door?....

Rgds,
Mark

Hi Mark,

Keep the manuals coming please! Always interested to see how others do things.

Craig.

like this?

Some Hawk schemes to compliment this thread. Hope it was not mentioned before

Well this thread seems to have ground almost to a halt. Anyone out there making progress ?
Regards, David Gladwin.

David

We are all still interested! You, I think, are furthest on with the build. We are all waiting for your flight report.

Best regards

John

Model finished(well its in primer). Waiting for decent weather to arrive and then I will test fly it.

Geoff.

Oh and yet to do them damn outer doors as well.

I know Tim Currie has finished and flown his Hawk successfully. Hopefully, he'll chime in with his very comprehensive flight report that he gave me.

Rgds,
Mark

PS E-mailed Hans Dieter asking for pictures/instructions of how to fit those *@*&%* outer doors as so many people were struggling. Funnily enough - no reply yet [&:]
