This is my 4th one of these servos I use them in cars as small as my 223s ARRMA VORTEKS 3s all the way up to my 1/7th ARRMA TALION EXB which is what this last one I got was for.... fast and powerful no external BEC required just install like any RTR servo and go and these servo can take abuse
Ive wanted to get a castle creation motor and esc for years just took the step over and oh my why did I wait so long love this set up and how fast it is..best set up ive ever ran..
