junkjunk junk no idea if the new castle stuff is better  im going to start replacing the crap in mine as the esc and rx are burned up  i think a 180a turnigy , a 3/16 flex and maybe say 5s parellel lipos and a 2000 kv motor will be my next choice. i will also be relocating the stinger offset to right a tad .  but imho stay away from it  its really a money pit
