the crashes were within 30 seconds from take off with I assume fully charged lipos.  the complaint was always, " i don't have control"  I take that in two ways.. 1. you really have no control, nothing. and 2. you don't have control as you expected..<div>I can't imagine that a large company such as e-flite would sell ESC that are so bad, that say 80% of people that use them, crash them..  on that thought i would say that there is a very good chance that the crashes at the field is due to pilot error.  People that say they are good rc pilots don't ever want to blame themselves for the crash.. lol.. I know very little about electrics as i fly nitro and gas, just curious on the problem of others at the field.</div>
