Quote: "RCM Product Review. Balsa USA TEMPO II.

The Tempo II is a parasol wing sport design that is kitted by Balsa USA, PO Box 164, Marinette, Wisconsin 54143. It is designed to be powered by an engine of from .30 to .45 cubic inches of displacement. The Tempo II comes packaged in a plain brown wrapper. This is a sturdy corregated box with no fancy label. In fact, there is no label at all to indicate its contents. It is available direct from Balsa USA only. The price, including shipping, is an incredibly low $17.99. The contents are packaged in a 'no frills' manner. By that we mean that the box is simply packed with all the component pieces and parts and a rolled plan sheet, neatly in place. There is no cushioning material, nor is any needed as the one piece shipping box is rugged enough to withstand all but the most abusive handling. Balsa USA utilizes United Parcel Service for shipping.

The balsa wood quality is very good, as is the die-cutting. The hardware package is good, surprisingly so, considering the low price of this kit, and a formed aluminum landing gear and ABS plastic wheel pants are included. Balsa USA also informs us that, while they continually strive to maintain uniform high quality in all kit component parts, any part that does not measure up to the buyer's expectations will be swiftly replaced free of charge. Just send that part to them and a replacement will be sent. The 36 by 48 in rolled plan sheet, while rather basic, is well drawn and accompanied by two 8-1/2 x 11 in pages of written assembly instructions.

Construction: The Tempo II is an easy aircraft to assemble. The wing, a flat bottom design, is comprised of balsa ribs, spars and sheeting, and is constructed in the conventional manner. The tail surfaces are all pre-cut from sheet balsa. The fuselage is assembled from die-cut sheet balsa sides and plywood doublers and bulkheads. The fuselage top and bottom surfaces are constructed from balsa sheet and blocks. The fuselage top, aft of the cockpit, is comprised of dowel stringers over balsa formers, which are ultimately covered with either fabric or film covering material. The wing support struts supplied with the kit, are cut from a wood that appears to be redwood. We felt that these pieces were rather soft for use as main wing supports and elected to cut duplicate pieces from rock maple. The strut pieces supplied with the kit would surely work, however, we preferred to use the maple for additional strength in an area that we considered to be more prone to damage, in the event of a hard landing. This is not a criticism of the kit pieces, but only reflects a personal preference.

The radio compartment is large enough to accept any radio system, including the older units that utilized large components. Access to the radio compartment is via a removable hatch that is built into the bottom of the fuselage. The pre-formed aluminum landing gear is mounted to the fuselage with a 1/4 in plywood mounting plate and the supplied ABS plastic wheel pants are designed to house 2-1/2 in diameter wheels. These wheel pants are relatively narrow in width. The popular wide 'balloon type' wheels can be made to fit into these pants, but it is a very snug installation. The use of narrower profile wheels (such as Kraft or Williams Brothers) makes the wheel installation much easier. We used Williams Brothers 2=1/2 in diameter wheels on our test aircraft..."

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.
