The encoder is again absolutely unique featuring a solid state, discrete encoder devoid of the now customary computer. It is here that the Mark 22 TX shows it's soft underbelly. No computer means no model memory and that can be a serious shortcoming to some modellers. However for the modeller who flies basically similar models then the host of unique features more than makes up for the lack of model memory. For those modellers who do not want to get lost in computer manuals with all their complexity and confusing language, and yearn for a smart transmitter that bridges the gap between the simple to operate old basic transmitter and the clever transmitter, then this transmitter bears close examination.
Programming is simplicity in itself being very visual in nature.
The encoder consists of eight identical sub-units designed around the most simple to use programming elements of all time, the three pin plug and potentiometer. TX is fitted with an identical three pin plug. Here is the secret of the absolute uniqueness and power of the Mark 22 transmitter. Once one channel is mastered and this is not difficult, all eight channels are mastered. The gain control on the toggle modules may be used to extend a suitable standard servo to 180 o rotation.
