I use this little fella
http://www.hobbyking.com/hobbyking/s...339&aff=981295
just drill 2 new holes in the chassis and use exotek posts or make a clamp out of an old piece of carbon and a couple of bolts
works a treat, great specs (very similar to Savox) and dirt cheap
has been in my micro for a good 6 months with no issues at all
