A single seat single engined high-¬wing monoplane with conventional three axis control. Wing has unswept leading and trail¬ing edges, and constant chord; cruciform tail. Pitch control by fully flying tail; yaw control by fully flying rudder; roll control by half¬span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile single¬surface. Undercarriage has three wheels in tail dragger formation; bungee suspension on all wheels. Push right go right tailwheel steer¬ing connected to yaw control. No brakes. Aluminium tube framework, with optional pod. Engine mounted below wing driving pusher propeller. Aluminium tubing is 6061T6 grade. Rigging is stainless steel cable. Wing covering is Dacron.

It is similar in layout to the Mk.I, but the control system has been changed to conventional three axis, with stick and rudder pedals.

The Skyseeker Mk.III is in effect a single seat version of the Mk.II, using the same control system and having very similar dimensions and only slightly lower empty weight. Apart from the seating arrangements, the most obvious difference is the use of 16 inch (41 cm) main wheels, as on the Mk.I, rather than the 20 inch (51 cm) type fitted to the Mk.II

This machine is supplied in kit form and the manufacturer says it takes 30h to build. Rigging time is listed as 30 min.

Floats, skis and instruments are available as on the Mk.I, while the Rotax engine can be replaced at customer’s request by a 215 cc single cylinder Cuyuna of 20hp.

Side by side two seat single engined high-¬wing monoplane with conventional three axis control. Wing has unswept leading and trail¬ing edges, and constant chord; cruciform tail. Pitch control by fully flying tail; yaw control by fully flying rudder; roll control by half¬span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile single¬surface. Undercarriage has three wheels in tail dragger formation; bungee suspension on all wheels.

The Skyseeker Mk.II is the two seater in the Skye Treck range. It is similar in layout to the Mk.I, but to fit it for its two seat role, the control system has been changed to conventional three axis, with stick and rudder pedals. A notable point is that whereas most three axis aircraft with single-¬surface wings use spoilers for roll control, the Skyseeker Mk.II uses ailerons.

Unusually for a two seater, the principal dimensions and engine specifications are virtually identical to the solo machine, the differences being largely confined to the undercarriage, where larger main wheels are used. As on the single seater, floats, skis and instruments are available as extras.

Single seat single engined high wing mono¬plane with hybrid control. Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Pitch control by fully flying tall; yaw control by fully flying rudder; no separate roll control; control inputs through weight shift for pitch/yaw/roll. Wing braced from above by kingpost and cables, from below by cables; wing profile single surface. Undercarriage has two wheels with tailskid; bungee suspension on main wheels. Push right go right tail steering con¬nected to yaw control. No brakes. Aluminium tube framework, without pod. Engine mounted below wing driving pusher propeller. Aluminium tubing is 6061T6 grade, anodized. Rigging is stainless steel vinyl coated cable. AN hardware.
The Skyseeker uses a taildragger undercarriage with skid.

The Skyseeker Mk.1 is a hybrid machine, with weight shift assisted by a rudder and elevator. Various engines have been fitted to the aircraft, but the usual one is a Rotax 277. However, there were also Skyseeker Mk.1s around with Cuyuna 215R engines, developing 20hp, or with single cylinder Kornet K 55 engines mated to a 48×20 inch (1.21×0.51m) propeller through a 2/1 reduction. Construction time is listed as 25 h and rigging time as 15 min. Options include floats, skis, and various instruments such as ASI, CHTG, EGTG, and compass. In addition, the factory will convert a Mk.I to Mk.III specification on request.
