D'une souplesse et surtout plus réactif. Mais a ce prix même pas une petite dose de frein filet pour bloquer juste les deux petites vis qui bloque le support sur l'essieu. Je trouve ça dommage vu le prix. Car si vous mettez pas de frein filet rien empêche les deux petites vis de partir sinon faut les serrer sur le servo et la franchement je conseille pas d'une vous allez le marquer voir écrasé le boîtier qui est en aluminium là vis et en acier elle. Aluminium vs acier c'est l'acier qui va gagner. Perso je vais raccourcir deux vis que j'ai pour les remplacer. Je comprends pas que injora n'est pas pensé à ça . ## Features - 【Brand Product】INJORA coreless metal gear high torque digital micro servo, high sensitivity, stable and low-noise. - 【Excellent Performance】 High precise metal gear, with better accuracy and longer service life. - 【Perfect Combination】This servo is equipped with metal mount and servo horn, replaces the original plastic accessories. - 【Application Scope】Water Resistant with O-ring seal, perfect for TRX4M Defender, Bronco, K10 High Trail, F150, TRX4MT 1/18 RC Crawler Upgrade. - 【Note】Not compatible with the original TRX4M servo mount and servo horn. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BTBR2PDC | | Age Range Description | Unisex Adult | | Best Sellers Rank | #52,562 in Toys ( See Top 100 in Toys ) #44 in RC Vehicle Servos | | Brand Name | INJORA | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 429 Reviews | | Educational Objective | Hand-Eye Coordination, Motor Skill | | Included Components | Servo, Servo Mount, Servo Horn | | Indoor Outdoor Usage | Outdoor | | Is Assembly Required | No | | Item Type Name | RC Servo | | Item Weight | 0.1 Pounds | | Manufacturer | INJORA | | Manufacturer Minimum Age (MONTHS) | 168.00 | | Manufacturer Part Number | INJS11-4MBK | | Material Type | Aluminum, Stainless Steel | | Model Number | INJS11-4MBK | | Number of Players | 1 | | Operation Mode | Manual | | Power Source | battery | | Set Name | INJORA Coreless High Torque Micro Servo | | Size | S | | Subject Character | RC Servo | | Supported Battery Types | No batteries required | | Theme | RC | | Unit Count | 1 Count | ## Images ![Coreless High Torque Micro Servo with Mount and Servo Horn for TRX4M TRX4MT 1/18 RC Crawler Upgrade Parts(Black) - Image 1](https://m.media-amazon.com/images/I/61JZOKOQpJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just skip the 7kg and buy this *by M***O on 19 June 2026* Much much better than the 7kg version esp if you have 1.3” beadlock brass wheels and large tyres ### ⭐⭐⭐⭐ Top du top mais ... *by Y***K on 13 August 2023* Rien a voir avec l'original la qualité est tout simplement incroyable.
