  1. Thank you all - most impressive how much knowledge of the equipment as well as the kits there is on here. I now know much more than before about British WW2 bombs, and what the kits supply. Not only that but a better idea of marking & painting schemes thanks to db. Cheers, John B
  2. Hello again all. Another Lancaster related query. I see the new Airfix Lancaster B MkII does not provide a bomb load - that can be bought separately. I have some spare bomb offerings in my stash and my spares box, so - The Revell Lancaster BIII offers bomb load options including one medium size cylindrical bomb and 18 small bombs. Is that a 4,000lb ‘cookie’ and a bunch of 250 lb bombs, possiblythe loading for say a V1 sites (‘No Ball’) ? I also have the second last Airfix moulding of the Lancaster I – the Battle of Britain Flight aircraft. A bomb load including a
  3. Thanks Ray and Graham especially. Graham, I agree that it's not fair simply to assume a poor or hasty installation or draggy nacelles etc. Just trying to find possible explanations. The ventral turret does look to have been fairly well designed, though presumably added weight. Prop type also may have affected things a great deal - thanks totd. (I recall a machine we made a small modification to, trying to reduce prop damage on gravel surfaces by adding a very thin layer of helicopter style blade tape. The effect was startling - poor beast could hardly get off the ground! )
  4. Wow, I didn't expect this. Most interesting discussion and much to think about, though a fair bit of thread drift from the original question. I like Graham’s early point about development being limited. Blending different engines into a new airframe is not necessarily simple., so it seems much of the additional power of the Hercules engines was being lost due to draggy installation, possibly plus some added weight. I had forgotten to check the height bands at which the various superchargers operated – thanks for that. John B
  5. For info, the latest state of play is that she has been lifted out of the water - by crane. That means she is safer from the probable high winds and waves later this weekend. It also makes the tasks a bit easier. A full engine change will be required sadly. Something internal is jamming the starter from moving. Expensive and slow exercise which will need scaffolding and some protection against the elements. The group running her is appealing for financial help - look up 'Miss Pick Up on line or see this 'GoFUndMe' page - https://www.gofundme.com/f/misspickup?fbclid=Iw
  6. Hi all, I am planning to build the new Airfix Lancaster BII, which looks like a bit of fun - and easier than my plan of many years ago which was to do an engine swap between an Airfix Halifax & Lancaster. Looking into the MkII, a question occurs. The Hercules engines were more powerful than the Merlins generally used in Lancasters, and yet the MkII apparently had a lower ceiling. Not sure about speed or weight carrying capability, though I believe they were generally more lightly loaded, later on in service. So - what went wrong? More power but poorer performa
  7. Yep, she was moored in the bay near Drumnadrochit for safety after the engine problem and tow. Unfortunately one of the blister windows was damaged by a boat somewhere in the process, so once the engine is operating the intention is to recover her to Inverness - Dalcross - and complete repairs there.
  8. Thanks, 'detail is everything' - most useful. What a good idea! Just enough info to tempt... John B
  9. Given that the canal was dug through river laid sediments, it is likely that the material yielded in a relatively fluid manner - this may be part of why that bomb failed to detonate originally. Generally a rapid deceleration was required to start the final detonation process for (say) a depth estimating timing. Slow deceleration in soft sediment.. That sediment will also cushion the explosion shock - and because the explosion broke through to the surface, it will not have formed the full cavern effect which was intended. Soft ground is a difficult target for artillery or bombs !
  10. An impressive length of time for that explosive to still be active. Someone commented about the relatively small size of the water 'spout' (?is that the right term?) Tallboy was intended to be a deep penetrating bomb I think, so presumably it ended up fairly deeply buried in the canal bed. That would have damped the surface effects; I wonder what the canal bottom profile looks like now!
  11. Thank you, 'work in progress'. That explanation helps, My word the guy down the back of the Mosquito must have been cramped for space. Much like the Hornet I suppose. Umm - I thought the Sea,mew looked marginally less ugly than the Blackburn B54 which lost out to the Gannet. Blackburn were good at ugly - the Buccaneer & the Shark were amongst their few bonny aircraft. Like 'fightersweep' I have a large stash of old Heller kits of French pre WW2 aircraft because they are so intriguingly different and ignore aerodynamics as we now know it.
  12. I'm with you 'alt92'. That is a dreadful thing to do to a Mosquito - and why? What does a target tug need a glasshouse up front for? Most odd, as well as ugly!
  13. Superb pictures. Interesting. I recall seeing the Pelicans and thinking the colour wasn't the Blaze Orange Dayglo that the Gnats & standard JP3s were painted with but a brighter colour, though also Dayglo. Fluorescent Red, which was rather heavy as an overall finish . I thought they were later repainted in Bright Red - 'Humbrol 19' equivalent as 'AMB' says, to save weight and to reduce fading. I recall seeing the Yellowjacks at Valley, though before they painted any of the fins black. I thought they were very neat and of course we had no idea what would develop from that. As S
  14. Not wanting to throw additional doubt into this, but weer these various shades of Sky or whatever affected much by fading? Might that be part of the explanation for the apparent variations? The maritime environment is quite punishing. Certainly sounds to me like a good way to excuse my modelling interpretation of the colours I use!
