Vecchio Not really bad luck either stupidity or a Seniors moment.

Tim Now that is what I call intelligence or common sense! I read somewhere never to run any motor without a prop. but it is something that I will always do from now on.

Thank you both smiley notfrown

Ted,

Sorry if I came across as somewhat brusque!

Now let's get this Cygnet in the air, shall we?

Tim,

You have nothing to be sorry for.

I have to wait because all the model etc. shops are closed most for two days. Don't forget there is a horse race on Tuesday and most places close on Monday and Tuesday. I've e-mailed the hobby shop but even if he remembers to put the new prop in the post it takes four full days before arriving on the doorstep. one dummy engine needs refit of elec wires, a couple of fins and inlet and exhaust pipes. These are elec. wire painted gold. Apart from that the model's raring to go.

Hi,

Has anybody else built one of these from the cnc kit? I have nearly completed the left hand upper wing and am looking at adding the riblets as the final job. Only thing is in the kit there is only one sheet with 30 riblets. As far as I can see there are 30 (29 and a bit anyway) required for each wing half. Am I missing a sheet of riblets or am I misinterpreting the plans?

Mind you there is no right hand wing shown on the plan either so who knowsindecision

Andrew.

Hello Andrew,

I'm not familiar with the contents of the CNC, so I'd suggest giving SLEC a ring, as they actually cut the kits.

Checked the packing/cutting sheet provided with the pack and that only lists one set of 30 riblets, so looks like it is an error in production. Will ring them on Monday to discuss.

Finally received another set of 30 riblets today. Looks like the cutting/packing list is wrong for the kit so anyone ordering this kit needs to check this.

Also check the wing spars provided. Mine were certainly not hard balsa, quite the opposite, they are cut from some very soft sheet. Either replace with hard balsa or what I did was to add a strip of 0.5mm carbon to one face.

Top wing is nearing completion. All 60 riblets in place and looking good.

Another issue with the riblet parts is that they are a tad too small. Compared to the front rib parts R1 they are about 0.75 mm to short. This makes fitting them interesting.

My solution has been to add a fillet to the rear of the LE and another to the front of the main spar. The fillet is the width of the gap between the riblets and simply fixed with CA. This then not only provides something to glue the riblets to but also aids in getting them properly aligned.

Should have some pics of the completed wing shortly.

Hi Andrew,

why not making your own build blog? I am sure a lot of people would enjoy that. It doesn't matter that Tim has described the build already, maybe you find some areas which you would do different or show pictures from different angles.

Hi VA, thanks for the suggestion but I am not sure my building skills are up to the same standards as some of the others on here so would hate to embarrass myself with a full blog.

As I am using the cnc pack then I think it is worth highlighting the issues specific to that for future builders. If I come across any other issues that I think need more explaining then I will add those in as well but so far between the original magazine article and this blog most things have been fairly clear.

Andrew
