I purchased a HL Panther and a HL Pershing from Mato Toys (both super versions). The Panther works beautifully: it's fast and powerful, and it ran for 45 minutes on a a full charge endurance test over mixed terrain. The Pershing is a disappointment: it is slow and weak (about 1/2 or less the performance of the Panther), and it only ran for 21 minutes on the same endurance test. The Pershing also does not seem to have the performance of the HL Pershing in the video on the Mato site.

I complained to Mato, and they are sending me a replacement metal engine box along with some other upgrade parts I ordered.

Does anyone else have an idea of how the Pershing is supposed to perform generally, and compared to the Panther?
