Thankfully I haven't had the issue of the Savox Brownout but I have helped a few people that have. A glitch bust should be all that is needed.
I am running mine off of an LRP SXX TC spec v2. I know the LRP's have a higher amp internal BEC than most other manufacturers so maybe this is why I haven't seen the issue.
I run a Savox in one truck only right now, just as a tester from Savox and I do like it. All of my other servo's I use are the AE 1015's. Great power, great speed, great price.
