That looks better :) Is the fin removable? If not, I hope you can get to that tailplane retaining bolt!

Yep. It all bolts together as per, Trevor.

I "came by" a ¼ scale ASW-28 the other day. It needs at bit of TLC, but it should be ready for our Scale Aero Tow on 4th of July. The Falke is feeling a bit out of it. :)

A quick shot of the fin and rudder . . .

I think that is a Pitot tube at the top of the fin.

Different lighting in each photo makes the colour comparison odious, but they look OK to the naked eye. :shock:

OK I haven't posted for a while, as I've been sitting and thinking.

The 'b' frames along the dorsal side of the fuselage are particularly ill fitting, with gaps of 1 mm or more. I resolved that by using micro balloons in epoxy to fill the gaps, with strength adding to the joints.

The most challenging issue is the trailing edges of the root rib pairs on each side. They should end in line with the longerons, but they are several milimetres too wide.

The same view on the plan shows their correct position.

So, I'm going to have to design a fairing piece for each side - otherwise there will be a sharp point sticking into the covering.

I'm still not getting emails from this forum, so I'll check back in a few days to see if there are any comments.

Cheers

What you must remember Max is that these plans were all originally hand drawn and as such are wide open to errors of all sorts.

I have checked all settings on your account re emails, there is no reason other than something at your end as to why you should not be getting notifications.

Yes. I get that now, Cliff.

I'm just a bit concerned that there would be a sharp point under the covering, so I'm thinking about how I want to deal with it. That's what is taking so long - the thinking. :P

I'm on several forums, and I receive around 100 emails a day - including RCSB and YouTube; notifying me of posts. The issue is unique to this forum. Having had my own forum, I understand how they work - and also that there are many set ups in design.

I've looked and looked my end, but I can't see the reason for the disconnect either.

I just mention it so people won't think that I'm rude when I don't reply straight away. I also pop in from time to time even if I'm not posting; to see what's happening.

Cheers
Max
