They're no longer limited to small electrics and park-fliers though.
To true Jet... but Daven was speifcally looking for a small footprint RX, thus my comments.
Were also using this new technology (although its not that new anymore) in our larger birds... Multiplex offers several IPD RX's standard size and smaller.
We rigged Josh's 39% Aeroworks Extra with MPX's new 12 channel IPD synth RX for the 2004 XFC last year and have been using it ever since... We also have a few large electric with the smaller IPD's.
