For 370 type gear box you have to get the fat viper motor ### ⭐⭐⭐⭐⭐ Alles super. *by J***A on 2 May 2026* 👍 ### ⭐⭐⭐ Under-inpressed *by A***N on 12 September 2025* As stated in many of my other reviews, I am a big fan of injora products. Currently, I have purchased two of these. One with high-speed gearing and another with crawler gearing. One I left bone stock, one I tried programming. Both have the exact same hitch between 10 and 20% throttle where a big lurch in speed happens. This eliminates a lot of that extra slow crawling potential, and really diminishes control at low speed. Speed. Have tried a few different ways of mitigating the issue, to no success. Further, the motor seems to overheat really easily. It hasn't shut down yet, but it does get scalding to the touch which is concerning considering I haven't driven it that hard or for that long. Decent for the cost, but I ran into the same issue after purchasing the fat viper hoping it would be better. I think injora has a little bit more work to do on the programming for their electronics. Was really hoping for more out of this purchase. ## Frequently Bought Together - INJORA MBL32 G2 Waterproof Brushless ESC & 1721 Purple Viper Outrunner Motor for 1/18 TRX4M Ascent-18 Upgrade - INJORA Battery ESC Receiver Tray Double Decker Carbon Fiber Plate for 1/18 RC Crawler TRX4M --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/696026978-mbl32-g2-waterproof-brushless-esc-and-1721-purple-viper-outrunner](https://www.desertcart.hr/products/696026978-mbl32-g2-waterproof-brushless-esc-and-1721-purple-viper-outrunner) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-07*
