Yeah ive heard that savox needs an external bec, my savox is running off of my reciever for my flysky gt3b and works great very fast and strong. Not saying one day under the right circumstances it could brown out my reciever.
Yeah the exi d227 is what ive got, I think I wrote 2227?
I didnt think of wieght being a factor, I just thought usage would make it break. Like crashing or crawling and a wheel getting stuck would just become too much for some cheaper ones.
