Ian Lennox Posted November 16, 2022 Share Posted November 16, 2022 Just now, Ian Lennox said: I simply flattened the ends, bent them to the correct angle and drilled a hole for a small bolt to attach to a T nut glued in the wing. I'll post a close up photo asap. alias Mr Ficky Quote Link to comment Share on other sites More sharing options...
Mr Ficky Posted November 20, 2022 Share Posted November 20, 2022 Here's a picture of the aluminium strut. Sorry for the delay. Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted November 21, 2022 Author Share Posted November 21, 2022 Hi Ian, Elegant. Do you remove them for transport, or do they stay on the wing? I was thinking of using hinges, as Peter has done, so they can fold flat on the wing (which then can go in its protective bag for transport).

Lucas Hofman Posted November 21, 2022 Author Share Posted November 21, 2022 A little further tonight: I intend to laminate the wooden ridges straight onto the wing 4 laminations of 1.5 mm balsa and one thin ply should keep the cockpit in place I hope. I will try to make an opening cockpit as per the original. The long term plan is to be able to change the pilot for a small camera to do some FPV flying.

Mr Ficky Posted November 24, 2022 Share Posted November 24, 2022 Hi Lucas. The wing struts could easily be removed, but with this size aeroplane I tend to keep it built up as it fits in my van without any dismantling. Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted November 26, 2022 Author Share Posted November 26, 2022 Cockpit frame next. I laminate them from 1 x 1.5mm balsa with 0.4mm ply at the top: I laminate them on a piece of tape so the can be sanded square before gluing in place.

Lucas Hofman Posted December 2, 2022 Author Share Posted December 2, 2022 The canopy get form: It is the first time I make a canopy so big and complicated. Next will be to put som more framing in that is found on the fullsize: For the few foto's I have it lookes like the inside of the cockpit on the fullsize is light grey, so I was thinking of spraying the whole area with a grey primer. After that paint the the dashboard black. Mount the plastic after covering. Would this be a good sequence? By the way, does man only srew the plastic or is canopy glue used in addition?

Peter Miller Posted December 2, 2022 Share Posted December 2, 2022 I did the plastic mounting last. I used very tiny screws to hold it down with glue as well. At least it is all very simple shapes and curves Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted December 18, 2022 Author Share Posted December 18, 2022 (edited) A long time with no progress. Partly due to RC sailing and 5 club boats that needed some service. And I have been flying on ice for the first time this winter: But today a little was done: The canopy frame came out well and are quite solid. Maybe it will be an opening canopy some time in the future. The pilot was too high so part of his chest was removed. He is skrewed in place from below so he can be swapped out for a little camera some time in the future.

Lucas Hofman Posted December 18, 2022 Author Share Posted December 18, 2022 Next was the landing gear. I have a nice bending jig that bends 4mm piano rod easily. However, when fitting I found out that it was 1,5 cm too narrow. That was not my fault: the horizontal part of the landing gear is draw a bit narrower than the fuselage frame next to it. Now 1m rod is cut up in 3 pieces that all are too short.... Well, on the other hand I could have checked the drawing against the model. Then I would have found out. Now a trip to the model shop is needed before we can continue. Happy Christmas and many happy landings next year if I do not "see" you before.

Lucas Hofman Posted December 18, 2022 Author Share Posted December 18, 2022 Question about where the horizontal stabilizing should be. Should it be as in the following picture? Which means the elevator joiner should be mounted before glueing on the fin. Or should the stabilizer further back, so that the aft spar aligns with the aft spar of the fin? Regards, Lucas Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted December 18, 2022 Author Share Posted December 18, 2022 (edited) I think I saw the answer on one of the photograph in the build article. The stabilizer should go even more forward as on the picture above. @Peter Miller Can you confirm. Should it move all the way to the bulkhead. I cannot figure it out from the drawing. Looking one more time at the drawing I see on sheet 1 the forward fine and stab aligned at the front.

Peter Miller Posted December 19, 2022 Share Posted December 19, 2022 According to MY plan and the RCM&E plan the front of the tailplane is butted up hard against F-8 which leaves the gap in front of the fin post. I mention both plans because variations between the two are not unknown. I hope that sorts the problem out. Quote Link to comment Share on other sites More sharing options...

Here is a photo of one of my ba=race attachment points @Peter, are both sides like this, or do you have a possibility to adjust the length at one end?

Peter Miller Posted December 24, 2022 Share Posted December 24, 2022 Hi Lucas. There is no adjustment on the wires. They are quite firm and nothing should make them come loose. Even if they did slacken off they would still do the job as they would stop a control surface braking as they would transmit all the loads as soo as it moved enough to tighten them. Happy Christmas. Here the temperature is at civilised levels at the moment. These days I fly by the 10-10 rule. Wind below 10mph , temperature above 10 degrees.

Lucas Hofman Posted December 28, 2022 Author Share Posted December 28, 2022 Bend the landing gear tonight. it is always difficult to get both legs symmetrical! I glued some light ply strips on the bottom to lock the 4mm legs completely in place: Hope to glue to tail feathers i place tomorrow.

Peter Miller Posted December 29, 2022 Share Posted December 29, 2022 A bit neater than my usual system for clamping them.Must do that in future. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted December 29, 2022 Share Posted December 29, 2022 I normally sink the clamps down to the 1/4 ply through the bottom sheet but I admit that it looks untidy. Adding the extra ply is so much neater Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted December 30, 2022 Author Share Posted December 30, 2022 I always try to do some "new things" with every build. In this case I would like to use Robart pin hinges, so that the hinge line can be 3 mm behind the aileron leading edge. Like on the full size. However, trying to drill the holes (in a test piece of the same thickness as the aileron) I did not manage to prevent the holes from coming through the surface. So the fallback solution is the well known fuzzy hinges. Tonight I made all the slots: 1 Quote Link to comment Share on other sites More sharing options...
