Even if he did - with current postage times - I'd have things fixed before any replacements arrived. No I wasn't expecting him to provide replacement prints free of charge, but he might be able to correct the CAD for future prints, or even for his own use.

Iain Posted May 20, 2020 Author Share Posted May 20, 2020 I mentioned the step at the base of the rudder earlier - that had to go - so out with a 10A scalpel blade again and this was removed. Removal very straightforward - and we're left with more loose strands of ABS that I'll leave in situ as they'll provide a little extra strength as part of the next step. Back soon.

Iain Posted May 20, 2020 Author Share Posted May 20, 2020 A small Milliput 'dam' added at the rudder hinge end and the area subsequently filled with casting resin, after masking the sides and raising the tail so that the area was perfectly horizontal at the top and a meniscus of resin allowed to form before it started going off. This area will now be sanded back using my 'T' bar - so it's perfectly flat. Just working out best positions to bond in some brass tube to act as mounts for the eventually to be replaced tailplanes... Interior structure as printed - note the box structure for the tailplane: More progress on cockpit section too - will take some photos tomorrow. Night all!

Iain Posted May 21, 2020 Author Share Posted May 21, 2020 Hi Anthony, Thanks - already have that one - but, yes, the contours are quite complex - and we need better photos! I'm going to proceed for time being with the rear fuselage section - fit tubular mountings and fill the voids with resin and make surfaces good - i.e. the fuselage contours. Tailplanes can follow as and when... Iain Anthony in NZ and ctayfor 2 Link to comment Share on other sites More sharing options...

Nothing on the elevators is horizontal... The only perfectly horizontal section is the triangular fillet between the inner end of the elevator and the fuselage - abuts and aligns with the para drop guard fitted in that picture. There's a photo somewhere in the folders that shows this section on the production line before tailplanes fitted.

Iain Posted May 21, 2020 Author Share Posted May 21, 2020 Anything appreciated Anthony - it's such a hard part of the airframe to access! My initial thoughts were to see if I could cut the horizontal triangle section (leaving the tail in situ as printed) and then 'blend' the root ahead of that - but that didn't work at all - and, because the dihedral starts from the root as printed - it sets the tailplane too high on the fuselage. The root extensions as moulded will have to go too - I think they're too thick and should have a slight downward curve on the original - but I do have a plan coming together in my head. All fixable IMHO - we just need a few more details! Iain ctayfor and Derek B 2 Link to comment Share on other sites More sharing options...
Iain Posted May 21, 2020 Author Share Posted May 21, 2020 Meanwhile - a couple of snaps whilst I made a coffee... This is giving me a lot more confidence with how to tackle the material.

Radders Posted May 21, 2020 Share Posted May 21, 2020 How are you doing the clear areas Iain? Cutting out from plastic and inserting? Making any form of lip for them to sit on at all.. ? Great work btw.. Derek B 1 Link to comment Share on other sites More sharing options...
Iain Posted May 21, 2020 Author Share Posted May 21, 2020 I'm going to have a play with the clear sections provided in the kit - but I'll probably get some flat polystyrene sheet and superglue in place, before sanding flush and polishing. Are those little Tic Tac clear containers still polystyrene I wonder? Iain Derek B and ctayfor 2 Link to comment Share on other sites More sharing options...
Iain Posted May 21, 2020 Author Share Posted May 21, 2020 Looks like Toshihiko has picked up on comments re. tailplane - I don't think this completely fixes it - but it is a big improvement. Also looks like he was working from the Aviation News plans... Iain HerculesPA_2, LSP_Kevin, Derek B and 4 others 7 Link to comment Share on other sites More sharing options...
