[RCSE] Re: [balsasailplanes] Building A Viking

[WB6ZHD]

I built a Viking with 2 sets of wings. The Mk. I and the Mk. II. I built it in 1978 and crashed it (while teaching a beginner) in 1997, the same year I won the Nostalgia event at Visalia with it using the Mk. 1 wings. The Mk. II wings are gone but in 1980 I won a F3B practice contest with them (2.5 lbs. of ballast for the speed run).
The only modifications I would recommend are 
1. strengthen the center section as protection against our stronger winches.
2. strengthen the area where the vertical stabilizer is mounted to the fuselage.
A little carbon fiber and epoxy will do fine. I did those mods when the plane was 18 years old.
I had also added 1/8 x 1/4 hard balsa diagonals between all wing ribs. 1 per bay.
And remember this. Zoom launching is not necessary. You won't gain enough extra altitude to justify the strain on the old design wood wings. Great plane. I have another Mk. I ready to cover.

You all can see the way I have changed the kit by 
looking at the three photos of the wings I'm building on my web sitein 
the RES..Nostalgia..Sport page, just keep scrolling till you arrive at the 
Viking info. My Viking kits includepre cut 3/8 vertical shear webs 
as seen in the pics, I added the carbon to both spars which is not part of the 
kit. Take a look at the Windrifter parts to see how the Viking kits are 
put together.
Laser cutting allows many improvements to the old 
balsa wood designs.
