The product support is actually through Hobbico, not Arrma itself.
This is the best outcome of the Hobbico purchase.... customer support. If you ever call for technical support, the operators are usually people in the hobby... and they start carrying on conversations about their own stuff or a friends stuff. Hobbico being so big and a owner/distributor of many brands, they usually can help you out.
Brands I choose to support:
O.S. Engines, Savox Servos, KO Propo, Dialed Inc, Sweep Racing, A Main Hobbies
