I installed the second one that evening and attempted to start my car, but as soon as I applied power to the starter I heard that all too familiar snap and the second one was destroyed. When I pulled it out of the back plate, needle bearings literally fell out of the casing. These are not worth the money... ## Features - Compatible with Vertex VX .18 .16 .SH21 12mm Engine, VX 12MM 110 Nitro Engine - Material: Metal.Durable in use. - Replacement Part No.: R025;Easy to install and remove. - Pack of 2.Spare part for 1/10 Nitro Engine. ## Technical Specifications | Specification | Value | |---------------|-------| | Model Number | XZ113 | | Batteries Required | No | | Batteries Included | No | | Material Type(s) | Metal | | Colour | black | | Package Dimensions | 2.49 x 1.4 x 1.09 cm; 9 g | | Item model number | XZ113 | | Manufacturer recommended age | 14 years and up | | Manufacturer | Mirthobby | | Country of Origin | USA | | Item Weight | 9 g | ## Images ![2Pack Mirthobby 12mm Hex Nut One Way Bearing for Vertex VX 18 16 SH21 12mm Engine RC Nitro Car Buggy Monster Truck RC Pull Start Parts - Image 1](https://m.media-amazon.com/images/I/61aOimLRkoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hpi *by M***Z on 14 December 2025* Great product happy customer ### ⭐ Save your money, buying these is pointless. *by K***. on 29 September 2025* I installed the first one of these and managed to start the car twice before it stopped working, it just slips inside the casing and won't turn the crankshaft.
