[1] The undercarriage was of the split type required by the torpedo dropping role, but a carrier mechanism between the legs could also hold a 185 imp gal (840 L) fuel tank for reconnaissance work.

He had a Scarff ring-mounted .303 in (7.7 mm) Lewis Gun, but to fulfil his role as torpedo or bomb aimer, he moved into a prone position in a station below the pilot's cockpit.

[1] The Beagle was initially powered by a 460 hp (340 kW) Bristol Jupiter VIIIF radial engine mounted in a smooth and rather pointed nosecone, leaving the tops of the nine cylinders exposed.

[1] Trials took place at RAF Martlesham Heath in July 1929, where the Beagle was ranged against the Gloster Goring, the Handley Page Hare, the Hawker Harrier and the Westland Witch.

[1] None of these aircraft met the performance requirements, but as it had received favourable handling reports, the Beagle, along with the Vickers Vildebeest and Hare, was chosen for further testing.
