Ch07 - Fuselage Exterior

First the supports to hold the foam in place.

That`s I saw in Bernard Siu site.

Inside line of 1.25" to cut at 45 degrees, and to show the 0.25" of the longeron.

The sand tool.

I go to speak to you, if you want to build an airplane of foam and glass be prepared for many grease in the elbows. You go to stress yourself, and many times you think about abandoning. But from there stops a little, some days, watch a movie, goes camp. Some start and do not finish, others delay 8 or 9 years constructing.

In my case I go to Araguaia river to fish some Tucunarés(like black bass), 120km from my house, or Tocantins river, 50km.

 

The most quickly build until today, spend 1.5 year to finish one Cozy.

My first piece was in 07/12/2007, aprox. 7 months and 22 days. I will beat that record?

I think the elimination of the naca, is easy and makes my building process more quickly here.

I think that this kind of modification is signed to me, nobody done that.

The shape of the foam with the bulkheads, no gaps.

Another shot. The 3 pieces of foam make the curve for the floor.

The black line is the 25" transition to the firewall.

Transition to the middle of the landing brake to the aft bulkhead.

After 20 days carving the fuse I made the 1" chamfer of the landing brake and in the F22.

The micro was to excessive carving, so I put some dry micro of 2mm to make the curve nice. Hard shelling is not so good, I just use this when I have to make some corrections.

3 ferrite toroids in the RG58U 50ohms. With the 1/2" gap between the copper tapes.

Marker Beacon was 34.3" each arm.

The NAV are 22.8" to 10 at 30 degrees.

29/07/2008

Laminated 1ply BID KK205 @0/90 and 2ply UNI @30.

I think my fuse is good to hard landings, or emergency landings.

06/08/2008

Cut off in front of F-28, WL18.9" to 6.25".

 

 10/08/2008

Finished the contours, now I will prepare the ballistic tape stream.

End of ch07, sides glassed @30/-30/0.
