sanwa recievers

[zoaman]

I have 4 sanwa rx (451/471).all have gone faulty with the same thing.they all worked for approx 6 months ok.now when you first turn them on only steering works.then after approx 1 min the esc works.this gradually got worse over a month.as these are not xheap I wondered if they can be repaired. Also I have bind them and still the same.i have looked on there web but no numbers for the uk.just wonder if any body knows a number fir sanwa recievers.
