X5 Wakefield (oz9108)

About this Plan

X5 Wakefield (The Argentinian). Rubber competition model.

Quote: "The great South American model that tied Britain and America in the last [1953, Cranfield] Wakefield contest. TheArgentinan, by Eliseo Scotto.

At the '53 Wakefield Contest at Canfield, England, no less than three entrants scored three-flight maximums of 15 minutes - with America's Joe Foster placing top in the subsequent fly-off, to collect the famed Blue Riband rubber trophy. However, in accordance with the existing rules, the official result was that the Wakefield Cowan was won jointly by the USA, Great Britain and Argentina - the three countries which tied at the end of the third round. Foster's model has already been featured in MAN and now we give you Eliseo Scottos Argentine design - a sleek polyhedralled slabsider with a two-bladed folding prop.

The one-quarter scale plan on the adjoining page is fully dimensioned for enlarging - while full size root and tip ribs for wing, stab and fin are given at the end of this article. The original model had a very light airframe, but now that rubber weight for future contests has been cut to 2.82 oz, harder balsa may be used to bring the all-up weight to the requited minimum of 8.113 oz. Bearing this weight question in mind, the larger of the nearest fractional sizes have been chosen in convening msterial sizes from millimeters to inches. For flying under the new rules. Scotto specifies about 40 ft of 1/4 x 1/24 Pirelli arranged in 14 strands (tensioned to the 31-1/4 in distance between hooks) - turning a 19 in dia prop of 27 in pitch.

At the Cranfield Contest, the model was flown on a 32 strand motor of 1/8 x 1/24 Pirelli. The prop used was a 19-1/2 in dia x 30 in pitch, as shown on the plan. Number of turns in each of the three rounds were 1,300, 1320 and 1380, -Unfortunately, this killed the motor, and for the fly-off, a new unbroken-in one had to be used, which was only given 920 turns..."
