About this Plan

SPAD SVII. Radio control scale model WWI fighter biplane.

Timely Plans no 212.

Direct submission to Outerzone.

Update 13/6/2023: Added article, thanks to Jean-Marie Piednoir.

Quote: "Our scale model replica carries simple radio gear for rudder only. A K&B .19 is mounted upright in the nose, turning over a Tornado 11x14 nylon prop. The receiver and batteries are fastened in the lower areas of the fuselage between the landing gear mountings. A Bonner Vari-comp escapement is mounted just inside the cockpit.

All scale details are held to a minimum, thus reducing the overall weight picture, resulting in an easy flier. The 43 inch model is low on speed, high on looks and performance. The entire model is covered with silk or light nylon.

The fuselage is as good a place as any to start. The basic structure is 3/16 sq balsa box construction. All formers are 1/8 soft sheet balsa. Upper and lower stringers are 1/8 x 1/4 medium grade strip balsa. Side stringers are 1/8 sq. The three plywood formers are 1/8 stock with 3/8 x 5/8 hardwood motor bearers.

Fashion the cowling from laminations of 1/8 sheet balsa. From aft of the cockpit forward, the fuselage is balsa strip-planked with 1/8 x 1/4. You will note, the cabine struts are 1/16 plywood fastened to the upper and lower longerons, with a large hole to reduce weight. This plywood member rests flush with the sides of the fuselage, and the planking running over it. 1/8 thick balsa stock is fastened to each side of the struts, building up their cross-section and further stiffening them.

A somewhat large opening in the top of the fuselage receives the engine. The builder should employ an exhaust stack to carry off the gases and reduce fire hazards as well as fuel residue. The stack can be fashioned from .015 thick aluminum sheet.

The landing gear is a simple affair being designed for easy access to the radio gear and in mounting the lower wing assembly. A pair of 'V' struts of 1/16 plywood, backed by 1/8 hard sheet balsa is the landing gears basic configuration. Sections of 3/32 dia music wire are used to reinforce and pivot the forward portion of the gear assembly.

To place the radio and wing in position, the gear assembly swings forward. The pivot itself is secured to the plywood bulkhead. This consists of a brass tube to receive the 3/32 dia wire, with two brass straps soldered to the tubing. This assembly is secured to the former with No. 4-40 bolts and nuts. The rear mounting utilizes but one strap as indicated in the plans. The spreader bar which carries the axle is laminated sheet balsa..."

    ScaleType: This (oz14617) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/SPAD_S.VII
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

With an escapement, switch and hinged rudder, this is not a free-flight model but a rudder-only radio-controlled one, for the brave amongst us...

Got it, Thanks. Have set this as RC now.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
