Difference between Sanwa RX-471W and RX-481WP

[hgatjens]

I am looking at a new receiver for my 1/10th scale electric hydro. I see Sanwa has 2 different Waterproof receivers. One is the RX-471W and the other is the RX-481WP.

The 481 has an internal .antenna and the 471 has an external one. Outside of that with the limited info I can find there doesn't seem to be much difference. Are there differences I should be concerned about? Is either antenna configuration preferable?

Anyone know any more or able to make a suggestion? They are relatively the same price. They both work wit the same transmitters. Mine is an m11x

Since no one responded I had to do my own test. Bought the W481WP and put it in my 1/10th scale Bubble Bud. Three races, three victories absolutely no issues. Easy to install when you don't nee to worry about th antena
