Lucas Hofman Posted January 16, 2018 Author Share Posted January 16, 2018 Progress again. Wings always cover quickly, but it remains difficult not to get dustparticles under the covering. I found that if I use a tack rag just before covering a section it usually goes ok. Cheers, Lucas Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 17, 2018 Author Share Posted January 17, 2018 A little like ugle duck - beautifull swan: Upper wing done: Now I cannot postpone glassing the fuse anymore ... Cheers, Lucas Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted January 18, 2018 Author Share Posted January 18, 2018 Thanks Ron. Another experiment: hinging ailerons with covering film. I got the idea from a glider with veneered wings where hinges are instructed to be done with scotch tape. Both for flaps and ailerons. This has kept well for 3 years and that gliders flies faster than most motor models. Hinge is done using 2 strips of 20mm wide covering: one under and one over. So far it seems slop free and pretty solid. The disadvantage with not following the trodden path is that one may find out why not everyone uses hinges made from covering film....

trebor Posted January 18, 2018 Share Posted January 18, 2018 Nice idea but don't fly too close to the sun ! I've got taped hinges on my Astrohog and they've gone a bit sloppy due to getting hot. Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted January 19, 2018 Author Share Posted January 19, 2018 Last nights production: Ailerons horns made from 1.5mm carbon plate. Easy to drill, sand and file, although you get black hands. Impossible to saw on a scroll saw so I did the cutting with a Dremel with a cutting disc.

Tim Ballinger Posted January 19, 2018 Share Posted January 19, 2018 Why the different size holes ? Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 19, 2018 Author Share Posted January 19, 2018 Ligtening holes. Only the outer one will be used for the clevis. Complete nonsense, but more in line with what you find in real planes: I assume it is now clear to everyone why my builds are quite slow ....

Tim Ballinger Posted January 19, 2018 Share Posted January 19, 2018 You know I was sort of guessing that would be your answer. Looks the biz though. 👍 Tim Quote Link to comment Share on other sites More sharing options...

A good part of my flying is like this: That may be so in the winter, Lucas, but you can fly all night in the summer You live in a beautiful country. Norway was the first place I ever visited where I needed a passport back in 1966. All dirt roads north of Bergen in my then girl friend's Mini. Nice job on the Skywriter. You'll end up with a lovely model. It's one on my list but the list is long and seems to be getting longer. Geoff Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 26, 2018 Author Share Posted January 26, 2018 Finishing touch for the rudder horns: Always difficult to mix paint so that the colour matches but a lot better then carbon black. Lucas Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted January 26, 2018 Share Posted January 26, 2018 Very good Lucas but you are going to have to start the resin covering sooner or later 😉 Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 26, 2018 Author Share Posted January 26, 2018 I may find something else I can use to postpone it a little more.... (but just now I cannot think of anything) Quote Link to comment Share on other sites More sharing options...
Martyn K Posted January 26, 2018 Share Posted January 26, 2018 Don't use resin, use EZE-Kote. Its much easier and cleaner to use Martyn Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 26, 2018 Author Share Posted January 26, 2018 Thanks for the tip Martyn. The video made it look very easy. No-one in Norway sells Eze-kote, so I ordered a bottle from SLEC. Hope it arrives soon. Lucas Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 22, 2018 Author Share Posted February 22, 2018 'Ordered long ago but it has not arrived yet. The friendly people at SLEC send a new bottle last week, but so far nothing has shown up. The time has been used to build a Microaces SE-5a, which had it maiden last Saturday: But I do still have finishing epoxy, so after reading up on how to glass a model the first bits were done yesterday (using 25 gr. duk): Dead easy. Tonight the remaining pieces and the bottom of the fuse. Cheers, Lucas Edited By Lucas Hofman on 22/02/2018 07:51:17 Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted February 22, 2018 Share Posted February 22, 2018 Looks big in the picture Lucas and really smart. Not sure my old eyes could spot it in the air though. I did build a free flight diesel powered SE5a in my youth so the picture takes me back a bit. Tim Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 22, 2018 Author Share Posted February 22, 2018 Here you can see it flying: https://photos.app.goo.gl/8nOrRoYt6WPn2kHA3 It is easy to fly (after balancing correctly). Building needed a lamp with a magnifying glass though. Lucas Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted February 22, 2018 Share Posted February 22, 2018 Excellent, never tried indoor flying , looks like some very solid walls that could get in the way ! Tim Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted February 23, 2018 Author Share Posted February 23, 2018 Now we are moving again. Did the another hatch, the bottom of the fuselage and the most difficult part (the cowling) yesterday. No wrinkles. Fuseside tonight, other side tomorrow and top on sunday: I want to simulate some panels, and need a high build primer I can use in a small airbrush. It will work with a 2-comp high-build epoxyprimer, but a one component (if possible water based) would be nicer. I will use water based paint as as a top color coat, but am still looking for a primer. Any suggestions? Lucas Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 23, 2018 Share Posted February 23, 2018 Hi Lucas, If you want to create panel lines, you're in need of a high-build FILLER not a primer. I would suggest a visit to your local car body shop and ask for a small quantity of a 'high-build filler' (mostly 2K), being preferably water based. And spray it on as you wish.

Lucas Hofman Posted February 26, 2018 Author Share Posted February 26, 2018 The last bit: That was much easier than I thought. One more coat with epoxy and we are ready for primer/filler. Cheers, Lucas Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted February 26, 2018 Share Posted February 26, 2018 Much progress Lucas. How do you do the joins? I am supposing feather , overlap and feather again. Tim Quote Link to comment Share on other sites More sharing options...
