I read on here about the Rio's ESC having some issues, and then Grim said wrote in that they had a bad batch of them, so hopefully that was the end of that problem. I have also read their "tech note" about letting the electronics cool if you run an 8.4 above 2000 mah. Our 8.4 is 3000 mah and it gets plenty of time before and after runs for cooling. If it pops within the next 3 weeks, I'll put the whole package (boat/radio, etc) back in the shipping box and return it for a refund! I really don't want to have to spend another $40-$50 on a "better" ESC. When my son and I were looking at what to get him, we were on the fence between the AQ Rio and the new BP Shockwave (brushed), which comes with a 45A ESC, teflon lined stuffing box, and runs the same stock props as my PB MG29. In the online videos, the Rio looked more stable, so that was a "plus" in my mind. Also, since the PB is "brand new" with really no reviews and ~$50 more, (but comes with a lower end charger (which I don't need) and EC3 connectors - all my nimh batteries are Tamiya), I chose to get the Rio, and buy a good 8.4V nimh hump pack. We both like the Rio ... it handles very well, runs flat, and is really fun with the 8.4, but, I guess now I'm starting to have second thoughts.
