The ST model Discovery is all about learning to fly radio control model aircraft for the very first time. The Discovery has been totally designed with that aim in mind and has all the ‘easy to build’ and ‘easy to fly’ characteristics that the beginner needs. What’s morethe time between opening the box and being ready to fly is measured in minutes not hours!
The computer designed structure has been optimised to give the best combination of stable performancedocile handling and durability. With etensive experience in designing complex EPO moulded models with carbon fibre re-inforcement and injection moulded plasticST Model have created a modern masterpiece in trainer design. Much of the structure is hidden deep inside but can be seen in strong light conditions as the EPO moulding becomes more transparent. For youthe ownerthat is kind of unimportant as it is all pre-built inside. All you will be doing is the final assembly with a few screws. Just four will have the airframe assembled and then two small grub screws need tightening up on the elevator and rudder servo pushrods. That’s it!!
When you are learningthe likelihood of a ‘less than perfect’ landing has been thought about too. There is a heavy dutysprung noseleg and tough aluminium undercarriage. That main undercarriage is screwed to a special plastic moulding incorporatedlongidudinally inside the foam fuselage. The screws are designed to pull out rather than damaged the fuselage in a heavy arrival.
The semi-symmetricaltapered wing with anti tip-stallcurved wing tips will give all the correct characteristics in both calm and windy conditions plus a docile stall. The ailerons are responsive yet progressive without giving over-control to panic a learner. In factthe same kind of progressive response comes from the elevator too. The rudder and nose wheel are connected for positive direction control on the ground and smooth response in the air.
Thrust is courtesy of a powerfuloutrunner stylebrushless motor and a 30A brushless electronic speed controller (ESC). The propeller is an impact absorbing 10 x 5 that has been matched to the motor for high thrust and low current consumption. A 3 cell 2100mAh Li-po battery (not supplied) will give over 10 minutes of flight time under normal ‘training’ conditions. There is room to fit a bigger capacity battery too if you want and it will have very little efect on the centre of gravity and handling. We recommend the XPower 3s 2200mAh 45C lipo battery.
As there is no gluing involvedreplacement airframe parts can be quickly fitted if necessary.
