A reference guide containing nitro engine settings and information for radio control vehicles as well as a handy pitstop calculator for nitro racers.

The pitstop calculator helps you to calculate when to pit for fuel in your nitro R/C races. Simply enter in how much fuel you've been using and it'll work out when you should be stopping to make things easier for your mechanic. It will suggest a sensible pitting interval as well as risky suggestions. You can quickly see how many fuel stops you can save by risking it... but will your car make the distance!

If you’re having problems starting or running your nitro vehicle, the best place to start is by setting the carburettor back to the default factory settings.

Carburettor needle settings are provided and where possible we’ve also provided the suggested fuel nitro content and optimum running temperature.

The app lists the engines either by vehicle or engine manufacturer so you can easily find the settings you are looking for. You can even bookmark your engines for faster access. Currently there are 400+ engines listed for multiple manufacturers - the database has online updates.

You can now share tuning/needle settings for your engines with the wider community. If you're looking for help with your engine, take a look and see if anyone has posted their settings. If your engine is running sweet, why not let others know the details? Now you can.

Browse the Engine Problems section to get help with your nitro engine. Common problems are covered with solutions and images to help you out.

Extreme care has been taken to ensure that all the information within the app is correct as the data has been collected only from distributors and manufacturer documentation. The information is provided as-is and we accept no liability for issues resulting from incorrectly adjusting your engine. If you are in any doubt you should either refer to your operating manual or contact your local hobby shop.
