    Hi  - selective sanding. I sanded the wings outboard of the booms and intakes. It still means the outer edge of the intake insert needs reshaping a little, but the boom-stub depth stays the same as does the wing to fuselage depth - so there's no step with the fuselage join or the boom join. It's not a 'perfect' solution but it avoids destroying surface detail.

    I actually think that the wing depth is too thick all the way across its chord where it meets the intake section. But that's virtually impossible to fix unless you create an entirely new wing.

    Cheers

    Ok
    So did you sand down the front and tip of the wing only or the trailing edge as well?

    Great work Bjorn!
    I bought this kit and I'm now reviewing it for a mag. I thinned the wing halves from the inside and that seems to have worked too. The bluntness on the leading edges seems to be in the middle of the leading edge, so sanding them thinner helps with this too- or at least it seems too!!  I also needed to reduce the depth of the wheel well walls too of course. In the pic, the left hand wing is unchanged and right hand thinned.

    Looking forward to seeing your finished model. Mine is currently destined to be a SAAF T.55.

    cheers

    How do you address the mating surfaces to the wings on the fuselage and tail booms?
    If you thin the wing halves, wont you get a step to the fuselage? so you'll have to sand that down as well? and the intake to?

    Yes your right, tis a plastic model, but at £50 plus and not quite right bit of a hard pill to swallow.  Thats why I stated earlier, give it a miss and save your money, buy another plastic model

    Well
    That's your very own personal opinion. I don't agree with you suggesting to others what to do based on your personal opinion.
     

    I don't mind the facts pointed out of what is wrong or right and let people make up their own minds if they want to spend their money on it or not.

    The fact that Bjorn has started a very informative build thread where he corrects  most of the issues with minimal effort speaks more to me.

    Me, I'm probably going to buy another one of these nice kits and be happy about it.

    What is difficult to understand and not a little sad, Is that PR has in the past designed very nice and very accurate kits. Of Swedish/Saab subjects. Why not this one?

     

    Looking at their J29 Tunnan (Flying barrel) kit  it has so exquisitetly and beautifully captured some rather complex and compound curves on the upper nose (where the nose meets the windshield) and rear fuselage (where the fuselage splits up in the upper boom and the lower exhaust). Now there are quite prominent differences between the later F and the earlier A/B/C/E fuselage, yet PR seems to have capture both fantastically well.

    I see no lack of pride, or amateurishness for that matter, even if their head (Claes) started alone, and on his free time.

     

    I wonder if he has had no/very limited access to a real a/c? The Swedish Air Force museum has one, but it has not been available on display for many years? And there is one at Svedinos car- and a/c-museum, but they are only fully open in July/August. It is approx. 500 km from where he lives, you just don't pop in and check things.

    His conditions for a proper research must have been much more difficult.

    Well..
    their previous releases are not perfect by any means, there are things that needs to be corrected.
    BUT, all previous releases are of Swedish (SAAB) built products which not that many people here are familiar with all the details about.
    Many of us Swedish builders just bite the bullet and correct what is faulty if we bother, not moan about it over and over.

    To continue.. Ok.. I think this is the weakest part of this kit,  the canopy.  I'm not sure how they would change this, other then to make a vacuum canopy.

    Their canopy is cloudy.. hazy.. but the framework is very good.  Even the small circular window on the canopy is there. They also give you 2 "frames" that go on the bottom of the canopy. This makes painting much easier. but i will need to figure out how to make the canopy "clearer"..

    3D-Printing has not come far enough yet to print clear parts successfully.
    They need to print a master to make a clear resin cast from or a vacuum canopy

    Depends what you're modelling.

     

    I'm assuming you're modelling a low speed, fixed pitch aircraft, therefore the pitch and blade twist would likely be similar to a modern light aircraft. 

     

    Pitch angles are typically 45 degrees at the root, decreasing by around 25 degrees to the tip. 

     

     

    Working on this in 1/48

    Copy what @hendie did in his previous post.

     

    The actual cross section doesn't really matter in 1/48 scale and smaller. An ellipse will satisfy the shape, strength limitations will require the prop to be oversized in thickness anyway. 

    Ok, I can buy that, but I would like to know how to get the pitch of the prop somewhat correct.

  8. Hi
    I have a propeller I need to make (using Fusion 360) but I only have the outer shape from the front of the propeller.

    I'm missing all cross section info, so I'm not sure how to proceed in making it.

    It's an early 1920's era prop, so maybe it could work with some generic prop shapes of that time if that is available.

    Any tips on how to proceed would be welcome.

    They did.

    And I answered all their requests including setting up 897's tail cone in my garage and building up a dimensional map of it, a week or so's work just for that bit.

    Sometime after I was politely informed the project had been dropped. Annoyed doesn't really cover it.

    I'd have probably helped PR (with grumbling and gritted teeth) if they asked, they knew we had a couple of Vamp's (F.30 & T.22)

    I help Airfix because they are the gold standard in manufacturers to work with along with Dora Wings. There's a resident short run chap here too who's no slouch.

    '

    What has been dropped? The Venom all together or just the Sea Venom?

    That is true. But I (and the rest, it seems) expect the new releases to be at least accurate in the shapes, if not in all the details. Even Eduard learned this.

    I hope that PR learn from this and that the Venom will be as good as it can be.

    With all this battering I highly doubt that PR will ever release a British subject again.

    It's a pity, I really wanted the venom.

    Johan, many thanks for the heads up!

    What do you think about the nose and windshield?

    Just curious, what do you think about the possibility to graft the Airfix wings to the PR  fuselage and booms? (Expensive perhaps, but may be worth it if one wants a really accurate two-seater?)

    Not sure about that
    the two kits have a totally different build up, where the airfix kit has a full span upper and lower wing with the fuselage incorporated in a single part.
    you would have to cut the wing parts of  and then reprofiling the mating surfaces to the PR fuselage.
    And then use the airfix booms with the PR fins and stab.

    A lot of work.

    Flygvapenmuseet in Linköping has Vampire T.55 (Sk 28C) 15745 and a Venom NF.51 

    https://plasticfantastique.com/walk_arounds/walk-around-the-de-havilland-venom/

     

    Another T.55 (Sk.28C) in Svedinos museum (between Gothenburg and Malmø)

     

    And there are also Vampire two seaters in Norway and Finland, including an airworthy one.

    The Venom, yes.
    I have not seen a two seat Vampire in the flygvapenmuseum collection in Linköping. Maybe they own one, but it's not on display in Linköping anyway.

    The Saab SK60, J29 and J21 models they produced look absolutely stunning and appear (to my limited knowledge) to be accurate - perhaps they simply have more knowledge of Saabs (being Swedish) than they do Vampires?

     

    I'm looking forward to seeing a full build review though!

    It all comes down to knowing the subject, that's probably why the Vampire gets such a trashing on this forum.

    Sk 60 and J 21 have a lot of small irritating omissions, faults and simplifications, but we usually see beyond that or just fix it.
