The problem is probably the tower hitting your motor plate (mounting lug of spur gear cover).

The solution is simple: Use 1mm shims between the tower and the gearbox and dremel a vertical flat spot on the mounting lug on your motor plate. It gives you a 2-3lmm clearance and will help a lot for durability.

In addition, arrange some 4mm thick Carbon Fibre towers (for example from Cream or Exotek). More recent batches of Durango's plastics should be avoided if possible: the factory that does the production of their parts seems to be cutting costs everywhere and it's affecting part quality - I've found numerous times parts are warped (poor fit) and/or retain internal stresses (=weaker).

Also, some DEX210V2 parts have weak areas from poor mould engineering (such as the V2 rear shock tower) - please carefully watch the quality of the parts you buy and in case the parts break suspiciously easily, don't throw away the evidence, instead contact the customer support. They can only improve the quality if they are faced with the issues, plus you have the right to receive replacement parts for ones where issues with quality are evident.
