Thank you for choosing the Knight 3D and welcome to Compass Model. The Knight 3D has been carefully designed to offer
out standing flight performance and includes many innovative features along with proven components to provide you with a
model which is accurate, durable and agile. The 3D was developed with input from leading pilots to meet the requirements of
the most demanding aerobatic flight styles, both now and in the future. The control system incorporates a closed loop push-
pull system for all swash plate linkages and optimum ccpm geometry to ensure unrivalled control accuracy and rapid head
response. Similarly, the frame lay out has been designed to create an extraordinarily rigid platform which is both durable and
further improves control accuracy. This compact layout features light weight, raised centre of gravity and unique engine
isolation mounting.
Please read the complete manual before assembly, which has been designed to enable you to get the best from your model -
please take careful note of all precautions and assembly tips. Please also keep the manual as a reference for part numbers and
reassembly following maintenance.
