B.E.2a - Flying Scale Models

The document details the history and specifications of the B.E.2e aircraft, designed by Geoffrey de Havilland and F. M. Green, with notable improvements made over its predecessors. It served primarily during World War I, particularly in reconnaissance and bombing roles, with a total of 1,320 units produced. The document also includes insights into the aircraft's construction, performance, and operational use in various theaters of war.

1: BE2e serial A1329, one of a group built by Napier & Miller Ltd. of Old Kilpatrick, the entire group was transferred to the RNAS. 2: Among the several tasks allo-
cated to the BE2e was that of Home Defence. The aircraft could hardly match a Zeppelin’s speed, rate of climb or altitude. This sample carries swivelling brack-
ets for two Lewis guns, two carriers for 100/112lb bombs and a pair of rocket tubes mounted on the interplane struts. 3: An unidentified BE2e fitted with a sin-
gle Lewis on a Strange mounting. In service many BE2es flew without the underwing gravity fuel tank. 4: One of the most unlikely aircraft to be used as a night
bomber some BE2es were employed in this capacity in France. No. 5844 was built by Bristol and after several makeovers, is seen here with No. 100 Squadron.
Painted black or dark grey it carries a single 2301b RFC pattern bomb under the fuselage, a pair of Michelin flares to the rear and another pair of T.W.R. flares
under the wings. To complete the set, Holt flare brackets are fitted as well as navigation lamps to wingtips and tail. 5: An unfortunate landing for a pair of train-
ing BE2es most probably belonging to one of the Schools of Aerial Fighting in 1918. Note the aluminium skinning fitted to the centre section to provide a firm
base for the Lewis gun mounts (or fire hazard) and the shortened exhaust pipes. 6: One of the problems with the entire BE2 series was the difficulty of defend-
ing itself due to the arrangement of cockpits. Everything was done by the pilot in the rear seat whilst his gunner had little room for manoeuvre. In this case the
single Lewis is mounted on a Strange mount and demonstrates the only area in which he had a moderately unhindered field of fire. 7: A BE2e of No. 47
Squadron in Macedonia illustrates the cluttered assembly of the equipment carried on an operational BE2e. Apart from the top Lewis on the Strange mounting,
another Lewis is fixed to the fuselage arranged to fire at an angle to clear the propeller. Within reach of the pilot are two bomb release levers and a framework
to hold a camera. 8: After the war vast amounts of aviation stores and aircraft were scrapped or sold. Among the miscellany of aircraft were a few BE2es which
went to Russia. In this alien environment was this BE2e photographed with its well insulated crew at the Red Air Fleet base at Sarapul in 1920.
