KO Propo have introduced their new EX-2 ST2 club-level radio system. The transmitter utilises the Extension Unit 2 steering wheel as well as upgraded angle sensors for the steering wheel and throttle lever that not only are about 100-times as durable as the standard potentiometers, they also offer a more linear output for greatly improved steering, throttle and brake feeling in both electric and nitro classes. The steering unit also offers dual ball bearings for the steering wheel shaft which optimises feeling and durability while a soft steering wheel return spring ensures a linear steering wheel feeling from the neutral point all the way up to the maximum operation angle. The ST2 transmitter is rounded out by the new V2.12 firmware as it is used with the high-end EX-RR transmitter. The radio system includes the compact size KR-241FH 4-channel receiver and it will hit stores at the end of August.
