The issues that cannon have been mentioning are non-existent in my area as well. Perhaps there is something going on in your local. Statments about substandard parts, materials, design, etc. are not entirely true nor do they reflect what most drivers are experiencing. The "poor quality of nyloc nut" with plastic nut holder have been around for ages and survive the power of 6-cell 3.5 Turn Brushless monsters so they should handle most applications with no trouble.
