Hy!
I just bought the HobbyStar RS472E L-shape receiver.
I installed it into my 1/10 4WD buggy. So far It works perfectly, and as good as the original Sanwa RX482 receiver.
Big test will be on the 26th of January in Slovakia at the Hudy Arena.
The first switch on was a little it tricky, but I figured it out.
I bought it from e-bay, and the seller told me, that this receivers signal distance is bigger than the RX482.
I will keep you updated about this receiver.
