The Hill Co. Llanberis Model 117HJb military flight training bi-plane was a further development of the civilian 320HP 117HJ.
This model included an update cockpit, 2 forward facing, small calibre (.303), machine guns (with an offset reticle) for target practise and an extended range fuel tank.
Using the uprated 360HP Newford Radial with auto cowl flaps the aircraft is still simple to control like it's civilian counterpart and a joy to fly (NOTE: lower throttle settings (55%) should be used to reduce fuel consumption and engine wear while in cruise).
