Quote: "Dear Mary & Steve, I attach a couple of plans as scans. I was not able to stitch them, so they will need some expert work [fixed now]. One is OFW 'Pete' Fisher's Dynos. I don't know if this was kitted by Performance Kits? Probably 1970's."

Update 27/5/2024: Added printwood (incomplete) thanks to Mark Robinson.

Quote: "Hi Mary/Steve, Please see attached a full size scan of part of the printwood for the Dynos kit, designed by OFW Fisher. Unfortunately I don't have the rest of the kit, there is presumably another piece of printwood containing the ribs etc. However, this piece is particularly useful having the formers for the nose section. Most other information, including the rib profile can be obtained from the plan. All the best,"

Update 7/12/2024: Added kit instructions, thanks to MarkRobinson.

Quote: "Introduction and Development: The 'Dynos' was designed as a super sports rubber duration model for the discriminating enthusiast. The design has matched an executive type appearance with a fine sports performance. The production prototype has been extensively tested under all weather conditions, and the kit model can be relied on to give a polished flight pattern, which is a joy to watch.

Wing Construction: Cover the plan with wax paper. Shape the trailing edges over each other to ensure symmetry of the tips. Shape to section and cut rib notches. Pin 1/8 x 1/8 trailing edges and 1/8 x 1/8 lower main spars over the plan. Cement ribs and top 1/8 x 1/8 main spars in position. Cement 1/8 x 1/8 leading edges in place. Remember to cant the root ribs on the outer wing panels to allow for 2.6 inch dihedral at tips. Use the template drawing provided on the plan. Fit the wing tip Formers W1 and W2 in place, and add wing tip struts. Cement gussets W3 and W4 into position. Ceilrent the three sections of the wing together checking the tip dihedral carefully.

Tailplane Construction: Cut the trailing edge to shape and notch for the tailplane ribs. Pin the trailing edge and lower 3/32 x 3/32 lower main spar in position over the plan. Fit ribs, 1/8 x 1/8 leading edge and top main spar. Fit tips S1 and S2.

Fin Construction: The fin structure is quite straightforward, all parts are pinned flat over the plan. When thoroughly dry, shape and sandpaper to airfoil section.

Fuselage Construction: Pin the 3/32 x 3/32 longerons and F10 in position over the plan. Cement the 3/32 x 3/32 uprights in position followed by F1, F9, F11 and F14. Build the second side over the first; remove from the plan, and sand to ensure identity, separate with a razor blade. Fit the 3/32 x 3/32 spacers and nose formers F3-F8. Great care should be taken during this operation to ensure that the fuselage remains rectangular in section when seen through the nose aperture; and also that the top view is as shown on the top elevation of the plan..."
