  1. Like this.... So if my rails and rail guides actually fitted into each other, then the flap would close right up. That's a step too far for my plastic bashing, but it'll look OK with the flaps deployed to some extent.
  2. Good one, @dcrfan! So that was a fair old chunk of plastic cut from each side of the moulding underneath. This next bit, you may or may not want to act on it..... Now that I've got a wing out for a look, there's a couple of things to sort. Ignore the lines, this one is not for nacelle mods! The flap guide rails on top of the trailing edge extension shouldn't be there. The extension strip was added on TOP of the rails. They're coming off. I didn't know this when I foiled one wing last year. So I removed the foil on the strip and did those too. I'd already done this on the underside, You can see that the flap has the t.e extension as well. I'm off the opinion that this is wrong Having looked at many photos of Lodestars and Venturas I'm convinced that the flap is NOT extended...... It's parallel front and back, just like the Hudson flap. The whole aerofoil cross-section wasn't extended. The modification is just a flat strip attached to the top of the rails. When MPM Special hobby released the Lodestar 1.72 with the Hudson wing and a pair of pe strips to glue on the rails, they got a lot of criticism for "taking a cheap shortcut". In fact, I'm saying that they got it precisely right! So my next step is to take a knife to the flaps and trim the extension off between the rail runners. Which is a bit of a pain because I've already built up the inside of the flap, I had to do the same thing on the Academy Ventura.
  3. Just sketching on the Ventura wing top where Id say the nacelle should join, Ticked line is existing, inner line for the Lodestar
  4. That's the spirit I think I'm right in saying that the Hudson engine arrangements are much the same as the Lodestar. The MPM Special hobby Lodestar kit supplies the Hudson kit basically plus the new fuselage and a Tailplane with the separate elevators marked, and the trailing edge extension strips . Same engines (plus the other ones that I used) and cowlings (which I had to modify). So it's fair to say that the engines, cowlings and nacelles are the same. I think I read that something like 70% of Hudson components are on the Lodestar.
  5. It's more like "dynamic... something" I think, Moa
  6. Ventura nacelle on top.... Lodestar nacelle on top.... .... and underneath, with no doors, As opposed to the Ventura with doors... I have hope that the nacelle shape on the big Revell kit underneath BEFORE the nacelle sides are added may be about the right shape and size to be made into the Lodestar type. But it's only a hunch Have you any more drawings, Dennis?
  7. Still figuring it all out, Dennis. The big P&W Double Wasps are 2 banks of 9 cyl The more popular Lodestar seems to be fitted with Wright Cyclones which is a 9 cyl radial. Like a Hudson. Some have a P&W Twin Wasps installation..... These are 2 banks of 7 cyl. You can tell them by the cooling flaps around the cowlings. Both of these are smaller in diameter than the Double Wasps on the PV1. So the nacelles are bigger in diameter too. On top of the wing it shouldn't reach so far back. Under the wing should be smaller too, and uc doors deleted. I'll find some pictures of the 1.72 builds for comparison. Nacelle shape on top of the wing is a pain. I think it will have to be cut out, wing surface repaired and a new smaller nacelle top made. It's gonna get messy
  8. Nice to see these again @dcrfan Wondered if you had made any progress on this? Yes, the engines and nacelles are the big issue for making a Lodestar. I'm OK with this one though
  9. That's what I was thinking. So I'm still dry fitting and I'm making use of the hollow fins now by inserting hinge strips in the gaps. I have a feeling that the tabs are active control assistance, in the sense that, when the rudder goes left, the tab goes right so that it is aiding the movement. Likewise up/down on the elevators. There's a proper term for the arrangement that escapes me for a moment..... All these curved edges are tricky enough to foil and sort the cut edges. The elevator by comparison is much simpler.... Each is one piece of foil formed over the trailing edge, allowing for the tab deflection, and the cut edges of the foil are up in the hinge line, out of the way.
  10. Some interesting exchanges turned up on this thread...... This site is the business for information exchanges and knowledge, isn't it?
  11. I'll be ready for it next time, Bill. The "next time" is the second PV1 kit, and the intention is to see how far it can be taken as the basis for a L18 Lodestar. So this build is the Guinea-pig tryout, along with the selection of 1.72 airframes of the various Lockheed Twins. That episode with the Tailplane is just the kind of information I'm after. As well as Dennis @DMChaving a kit on standby, I came across a few others on here as I gathered refs and information @dcrfan has a couple of kits and fuselages, including a resin one that's unusual. Wanted to flag you in, dcr, to see if you made progress with the Lodestar project I think I've about tamed the tail end structure now, and I'm wondering if I should fix it, or leave it safely to one side while I press on with wings etc. They're notoriously knockable
  12. The Reinforcement strips inserted into the void inside the fins has definitely helped to stabilise the Tailplane parts. Making a decent surface from the various bits is a little trickier. I think I'd set about this differently next time. The part inboard of the joint could come off with the rest of the elevator, the sandwiched thin wedges could be removed from the fin, and a new piece tailored to fit directly to the semicircular part outboard. And probably with metal fixing pins in the main joints. Just a dry fit to the fuselage here, but the excellent joint is evident.
  13. This is a great build and I think it's a real looker. Going to be fantastic on floats. And your references and research are second to none! Yea, you've got a few on the go at the moment. I hope the postal service picks up soon and you can complete with a grand flourish!
