See what your neutral setting is in the esc. I had to change it to 12 or 15% if i remember right. Less and it would not program. I run my 22418 in my lst with an outrunner on 6s with full brakes and it works great. I also had a ubec fail and take out the esc awhile back. Mgm repaired for no charge but it did take about 4 weeks.
