Rear axle hub carrier for HPI Maverick Strada MT (2017 edition, MV12623), original part number MV22009.

Also compatible with: Redcat Volcano EPX Pro, HSP Brontosaurus, Exceed Infinitive, Himoto EMXT-1, Amewi Torche Pro (which are basically the same car).

The model is done based on the equivalent aluminum part, which you can find for a few dollars on chinese sites and is probably much stronger than the printed part :-) however, in case you don't want to wait for shipping, this should be a good temporary replacement.
