Lots of sanding on the elevators tonight. I had the lapdog in the workshop, for reference, and I noticed I am the only one who has done the cut out in the leading edge of the elevators, well, on one so far! Looking at some of the full size photos, I think I will reinstate the leading edge on the notched one, and follow the herd! Pictures, when there is something worth looking at. Alex

I have made some progress, having spent quite some time on the hinges and the hinge pockets. They seem to soak up plenty of time with nothing to show for it! I think it's worth the investment of time though. When I have something worth looking at I will post some pics. Alex

Hi Nigel, I had to move those elevator ribs too. The tailplane certainly stiffens up when sheeted, and stays very light. Yours is looking good. Alex

Hi Danny, Looking at the retaining clip that stops the leg rotating rearwards, I wonder if it would be better if the load extended the clip, rather than compress it towards the fixing bolt. I wonder if repeated loads will fold the thin clip metal back, leaving a slightly floppy leg. It is entirely possible that I am over thinking this, but like you, I think the undercarriage is delicate looking. Alex (paranoid from Surrey)

Ahh yes, Dave. That picture was taken in the narrow time window between finishing it and actually using it. I am less inclined to show current pictures! Alex

Hi Martin, I'm a stander too. I have recently built the benches in my workshop, I kept 900mm to the top, standard kitchen worktop height. I did allow clear space for sitting, for the awkward elbow resting stuff though. Alex

Hi Danny, Seeing your comments regarding the flap/aileron lines, I agree it could end up causing major headaches, if total fidelity is the goal ( it must be a recognised condition!). A solution that shows some break in the shroud line will fool the eye sufficiently. Looking at various pics, it seems the aileron is almost parallel chord, moving the inner leading edge of the aileron out, would provide the shroud step. This might be something for the next scale mass build, chippy at 1/4 scale Alex

I feel a bit left behind at the moment, but there is no harm in having some of the bugs chewed out by Danny! I have had guests this weekend, so have been kept out of the workshop. My son did put in a request to the armourer, resulting in this little distraction. I had to sacrifice a bit of one of my slippers for the pouch though! It's good to encourage him to make stuff, you can have a good chat whilst he is semi-distracted, much more effective than direct questions. We may also be building a Keil Kraft Achilles together, about 40 years on from doing the same with my father. Here is a pic of the tail end so far. I am having a small crisis now regarding the aileron/flap lines, now Danny has mentioned it my eyes keep being drawn to them. Having not started the wings yet, I may try something. Alex

Danny, looking at the elevators in that picture, seems like the ribs are evenly spaced. I have just glued mine on this evening, and it now strikes me, that the first gap is bigger on the plan. i will have to check these with fresh eyes, in the morning! While I think about it, shouldn't we be doing the top of the rudder with ribs, instead of solid? Alex

Hi Charles, That is looking very neat. I look forward to following this one. Alex

You are romping on, it looks very neat. There is something very pleasing, watching the stripes appear on the ply as you taper it. Alex

Hi Chris, I like the extra deep leading edge, I could have saved myself a lot of careful packing. Great to see that you have started. Alex
-
I have removed the tail from the chocks and packers, and it looks remarkably straight. With the talk on other threads regarding the weight of the tailplane, I thought I had better weigh mine. At 28 gm, I am wondering if I forgot some of the bits. Alex Edited By AlexJ on 07/10/2014 22:22:42

I managed to laminate the fin leading edge this morning, so no waiting this evening. I used four layers of 1/16th and thinned aliphatic resin. I rolled a bit of a curve into them by hand first, I could have cyanoed it but didn't fancythat. Oh yes, I have coloured in the cyano lids, they kept hiding, it was driving me bonkers! Alex

Hi Barry, Good luck with the build. I'll be joining you with a four stroke , I will copy you with the laminated fin leading edge too, if that's ok? Alex
-
Hi John, I love the Gypsy Major. This is like a flash forward, very far forward, for me! So far, are there many things you will do differently on the next one? Alex

Hi Terry, I am just about to do the rudder and fin, I've stuck the flat bits together, and MK2ed it. I read on Danny's thread that your bottom rib was cut to the angle, I had just chamfered mine and stuck it on, so I went to check. Looking at the hole the rib came out of, mine looks pretty square, although it is a tiny angle, so difficult to tell, I should have checked before though. POF needs to be careful, if he passes too many negative comments regarding the finish, he might take another tumble off the bench! Alex

Well, I am a bit behind the curve, but I thought I would let the gurus chew the bugs out first. Here is the tailplane so far, I must apologise for not taking any earlier pics, but I got carried away with the cyano! I have gone with the plan regarding construction, rather than a core. The structure is really fragile, I ended up pinning the rear spar down, and standing the ribs up and zapping them. The leading edge was glued on at the ends, then zapped in my hands. I took the lead from Danny, and chocked the framework before the top skin went on with aliphatic. This was the first time I have used cyano for building models, it really makes you impatient! I did enjoy the smell of the balsa too, it took me right back to opening the box of my KK Marquis, when I was about nine. Alex
