You also stated that you use it in your yard. Might be hard to beleive but grass put a huge amount of stress on the electronics. Also the RPM's are a touch on the high side for a truggy, IMO you should have about 2000kv on 4s. My suggestion is to def bite the bullet on the motor. Spend a little more and buy a Medusa or the CC/neu from Mike $140 or less depending on what you choose. The MM should still be fine but don't keep trying to use it with that motor!
