Ripmax ST Discovery RTF 2.4 GHZ R/C
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 more, the time between opening the box and being ready to fly is measured in minutes not hours! This version includes the excellent ST Model 2.4gHz radio ssytem, flight battery and balance charger as standard.

The computer designed structure has been optimised to give the best combination of stable performance, docile handling and durability. With etensive experience in designing complex EPO moulded models with carbon fibre re-inforcement and injection moulded plastic, ST 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 you, the owner, that 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 learning, the likelihood of a 'less than perfect' landing has been thought about too. There is a heavy duty, sprung noseleg and tough aluminium undercarriage. That main undercarriage is screwed to a special plastic moulding incorporated, longidudinally inside the foam fuselage. The screws are designed to pull out rather than damaged the fuselage in a heavy arrival.
The semi-symmetrical, tapered wing with anti tip-stall, curved 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 fact, the 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 powerful, outrunner style, brushless 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. The 3 cell 1800mAh Li-po battery included should give around 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 Intellect 3S 2100mAh 20C battery as an alternative. Also included is the Pro-Peak Mini Mize balance charger that will have the battery re-charged and ready for flight in less than an hour.
As there is no gluing involved, replacement airframe parts can be fitted in seconds, should damage be incurred. They can be purchased from your local dealer. Keeping you in the air and enjoying model flying is a critical part of the design philosophy.
Once you have learnt to fly with the Discovery, there are many more exciting models in the ST range to temp you!
