RC Pit Calc Pro vs RTR

The RC gear ratio calculator trusted by racers and bashers — plus every other calculator you need at the track, in one free app. GEAR RATIO CALCULATOR Calculate gear ratio, final drive ratio (FDR), and rollout from your pinion and spur. Enter your gears "before and after" to see the real impact of gear and tire changes as a percentage (e.g. +2.5%), so you know exactly how much speed and motor load to expect. Built-in transmission data for hundreds of popular RC cars. PINION RECOMMENDER Not sure which pinion to run? Pick your car, enter your motor, and get a starting pinion from how racers in your class actually gear, plus the range they run. Built from real race setups across hundreds of classes. TOP SPEED CALCULATOR For electric cars with brushless motors: enter basic info about your setup and get a solid estimate of your car's top speed. PILL INSERT / SUSPENSION GEOMETRY CALCULATOR Find your toe, anti-squat, kick-up, roll center, and track width. Supports all popular cars that use pill inserts, and works with custom suspension mounts. CORNER WEIGHT CALCULATOR Enter your car's corner weights and get the full breakdown: front-rear, left-right, and cross weight/wedge. SHOCK OIL TEMP & VISCOSITY CALCULATOR Racing on a hotter or colder day than usual? See exactly what shock oil to run to keep the same car feel. OIL BLENDING CALCULATOR Don't have the right shock oil with you? Blend the thick and thin oils you already own — this calculator gives you the exact proportions for your target viscosity. SHOCK DAMPING CALCULATOR Compare two piston and oil combinations before you build the shock: roll damping, bump pack and jump pack side by side. Supports tapered pistons and dual hole sizes, with presets for common 1/10 and 1/8 shocks plus custom sizes. FUEL USAGE CALCULATOR For nitro racers: fuel burn per minute in race conditions, how much you need to finish long mains, and how many pit stops to plan. FEATURES - Remembers your entries for each car - Built-in data (spur gear, transmission ratio) for hundreds of popular cars - Walkthroughs and detailed help for every calculator FROM SO DIALED Want tuning help beyond the math?

RTR-Link是深圳市雄才科技有限公司推出的智能手机连接指定系列电调的应用，该系列电调内置特殊的蓝牙模块，用户通过这个应用与电调蓝牙连接实现对电调进行如下操作： 1.搜索到可使用的电调并显示。 2.对电调相关参数项进行读取与显示。 3.对相关参数进行设置，恢复默认值与保存。 3.电调版本设备信息显示。 4.对电调远程重启。 值得注意的是，因通讯协议的特殊性，蓝牙需要在电机未运行的状态下才能稳定通讯，且无障碍物的情况下通讯距离只有5米。 Description of the app: RTR-Link is an application launched by Shenzhen XC-ESC Technology Co., LTD. It allows smart phones to connect to specified series of electric tuners. This series of electric tuners has a special built-in Bluetooth module. Users can perform the following operations on electric tuners through this application and Bluetooth connection: 1. Search for available electronic controls and display them. 2. Read and display the relevant parameters of electric regulation. 3. Set the relevant parameters, restore the default values and save. 3. Electronic version equipment information display. 4. Remote restart of the ESC. It is worth noting that due to the particularity of the communication protocol, Bluetooth needs to communicate stably when the motor is not running, and the communication distance is only 5 meters without obstacles.
