Sanwa are about to release a new entry level RC, the MX-V. It seems to be less than half the price of the MX-3X and has all the features the average RC driver could wish for.
The grip and steering wheel position are similar to the MT-4. As it seems, it does not come with interchangeable grips and has a slower transmission mode (FHSS 2?) Other than that, I really like it - most probably this will be my next radio, as I'm not willing to pay for another MT-4 considering the little time I spent racing last year...
