Sanwa Exzes-X - Compatible Receivers

[Dal]

Hi guys

I recieved my Sanwa Exzes-X 2 weeks ago, absolutley love it.

I now have a need for another recieiver. I'm sure when I was researching the Sanwa radio's I saw that you could use other 'cheaper' recievers?

I plan on using it on a 1/12 pan car (non-racing). Because of this I'd prefer not to spend £70 on another Rx-451.

I've checked google again but not found anything concrete - was this only possible with radios where you can swap the transmitter modules as well?

Is the rx-451 my only choice? - Haven't got my manual with me at the moment.

Thanks

Dal!
