This set of plans (all 40 sq ft of them) is taken directly from the Avro/D H wind tunnel drawings for the B Mk II bomber (the final form).  All the ribs and formers are laid out plank-wise so it is possible to stick them directly to the planks with artist’s spray adhesive and then cut them out.  

There is a formidable number of parts to be cut so you may prefer to have those laser cut for you.  An excellent set of laser-cut parts is now available.

An estimate of the materials required for the model is as follows:

16 off  4" x 36" x 3/16" medium/hard balsa sheet.

2   off  4" x 36" x 1/8"                 ditto                                 

1   off  3" x 36" x 1/4"                 ditto                                  

1   off  6" x 36" x 1/16" plywood.                  

1   off  6" x 36" x 1/8"   plywood.

The above items will not be required if the  parts kit is ordered, you will also need:

2   off   1" x  3/16" x 36" trailing edge section.

45 off  1/4" x 1/8" x 36" medium/hard balsa strip.

30 off  1/16" x 4"  x 36" medium/soft balsa sheet.

2   off  3/8" x 1/2" x 18" hardwood engine bearers

1   off  5/8" dia x 36" tube to serve as building jig and wing reinforcement. 

A wing/jig tube as above is now available.  Part No V-JIG.

We can supply a set of vacuum-formed shapes for the upper and lower engine shapes plus cockpit, bomb-aimer's window, parachute hatch and electronic countermeasures bay (12 in all).  Part No V-VAC.

The builder will only be left with the job of forming the jet pipes - litho plate being a recommended material for that. 

The original model was pictured at the Nats in RCM&E August 71 and reviewed by the same mag in the following month.  It is big - 6 ft span and 9 sq ft of wing.  The fuselage is 5' 4" long but only 18" wide with the wings detached.  Even if you overdo the paint, a 0.60 2-stroke with pusher prop has no trouble getting it flying. 

Like most deltas it doesn't stall, it just mushes if short of speed. Doesn't drop a wing either (lots of wash-out). It will roll and loop and generally handle like a sportster. Take off run is minimal because of the low wing-loading: 10-12 lb spread over 9 sq ft doesn't amount to much and I flew the original on a Merco 61, not the most powerful of engines. I would get control flutter if I dived it too fast but that was with snakes to a central mechanical servo mixer, in-wing servos eliminate that.
