About this Plan

Tempest II. Scale control line WII fighter, for 2 - 3.5 cc diesel power. Scale is 1/16. From 1949 November Aeromodeller.

Quote: "A 3/4 inch to 1 foot flying scale control line model. Tempest II, by HJ Pridmore.

THOSE who prefer scale fidelity with their control-line flying will enjoy the clean, sleek lines of this Tempest II and its snappy flight performance. A third line engine cut-out-come-blip-switch makes landings a treat, and is useful in an emergency. It is not a beginner's model but has no vices, and for those familiar with control-line flying is a handsome addition to their stable.

Fuselage, etc. Commence as usual by pinning fuselage keel to drawing and cementing one set of half formers in position. Check that all formers are vertical and cement on one strip of 1/2 in x 3/32 in planking along datum line of fuselage. Remove structure from drawing and add formers and planking strip to other side. Next build up wing centre section directly on to fuselage, taking care to ensure accuracy. Reference to the sketches on the drawing should make assembly clear.

Install undercarriage and cover top of C /S with 1/16 in sheet and bottom with 1/32 in. Continue bottom sheeting up to fuselage keel. Next make and cement tail unit in position. Note that the sheeting on each side of fin continues on to fuselage keel for additional strength. Instal bellcrank, etc and commence to plank fuselage with 3/32 in sheet. Use strips about 3/8 in wide, tapering towards tail. Bevel edges of strips where necessary to obtain good finish. Cement ply firewall to F.1 and fit engine bearers. These must be a tight tap in fit so as to remain secure. If desired, 3/8 in sq hardwood bearers may be used in place of dural. Instal engine cut-out plate and choke lever. Next, thoroughly dope compartment between F.1 and F.2 to prevent oil saturation, and add the top balsa blocks to complete.

Cowling. Glue the hardwood cowling bearers in position. Laminate cowling ring from 1/8 in sheet and cut in two halves. Cement lower half to bearers, and add the attachment dowels in top half. Cowling plates are of 1/32 in sheet aluminium. Bottom plate is attached to bearers by small wood-screws, whilst the top plate is removable for access to engine, and is secured by two 20 swg clips.

Wing Panels. These are built up over the drawing as usual and covered with 1/32 in sheet balsa top and bottom. These panels may be permanently cemented to the centre section if desired, omitting attachment dowels and tubes..."
