Rye:

Its not legal for North American use. The legal NA bands for surface (land) are 27 and 75 MHz.

Thjats also a PPM (aka FM) receiver, not a PCM one. If your 8u is switchable, thats ok to use, if you can get it retuned from 40 MHz.

If its a cheaper than main-brand receiver that you want, try the GWS ones, the Naro and Pico units. About half the price of the Futaba ones.
