David Womby Posted May 22, 2019 Share Posted May 22, 2019 I see some photos on the web of built up models of Canberras (including PR9s) with a rectangular dark patch under the wing between the nacelle and fuselage aft of the wheel well. Some have it under both wings - for example XH171 on display at Cosford. The panels are black or faded black that looks brownish. I am modelling an early PR9 with silver paint scheme from 1963. Do I do one or two of these and does anybody have their dimensions, please? Thanks, David 1 Link to comment Share on other sites More sharing options...
DaveH Posted May 23, 2019 Share Posted May 23, 2019 Hi David... The B2's I worked on had a single panel, not sure which side. This was a dielectric cover over the Green Satin Doppler radar aerial. Later versions of Canberra had Blue Silk radar instead. This equipment gave true speed and angle over the ground... made navigation easier and more accurate. Maybe versions with 2 panels had a twin fit, would make sense in PR where navigation was more critical. Size wise rectangular panel approximately 2x4ft ( I think....but it was in the late 70's, so my memory might be off a bit) Hope this helps Dave 1 1 Link to comment Share on other sites More sharing options...

Thanks, David Hi David You're good to go with two doppler aerials, as DaveH says 4x2 foot sounds about right but I'll check that later.

sloegin57 Posted May 24, 2019 Share Posted May 24, 2019 There was also a further aerial on the forward part of the port flare bay door as shown on my photo of XH168 over my house in Paola Malta in the sixties :- HTH Dennis 4 1 Link to comment Share on other sites More sharing options...

John Thanks, John. I'll live with 2x4 as you and Dave suggest. It looks right. 5 hours ago, sloegin57 said: There was also a further aerial on the forward part of the port flare bay door as shown on my photo of XH168 over my house in Paola Malta in the sixties :- HTH Dennis Thank you, Dennis. What a completely stunning photo. I am actually modelling XH168 but in 1963 when she was with 58 Squadron and, a) because she was newer then, plus b) because my painting/weathering skills are just not up to it: I am modelling her much cleaner than in your photo!!!! I will, however, at least make sure those antenna are painted sort of fibreglass looking and not just black 🙂 David Link to comment Share on other sites More sharing options...
71chally Posted May 24, 2019 Share Posted May 24, 2019 Super shot Dennis! In later years the PR.9s had the single doppler panel (unsure of name, but seen on many British a/c), fitted under the port wing. 1 Link to comment Share on other sites More sharing options...
canberra kid Posted May 24, 2019 Share Posted May 24, 2019 @David Womby David I found this photo of 'your' PR.9 when she was with 58 Sqn unfortunately XH168 is the one furthest from the camera! The the extra aerial on the flair bay door appears to be the Radio Altimeter Mk.7B. but as yet I've not found a photo of an early PR.9 with one fitted? I can't say when the mod was introduced.

David Womby Posted May 24, 2019 Author Share Posted May 24, 2019 Thanks, John. I also found a good pic of XH168 with 58 Sqdn on aviationphotocompany.com. David 1 Link to comment Share on other sites More sharing options...
