About this Modpack

📝| Introduction

Flight Client is a 1.20+ optimization and Combat/PvP based client inspired by Lunar Client, Badlion Client, Hoplite Essentials and Combat Optimized designed for PvP Legacy and Hoplite however it works well with pretty much all servers.

🤔| Will I get banned for this?

This modpack has many mods all of which are safe to use on almost all PvP servers however there is a small chance of being banned make sure to check the allowed mods for the server you are using this on. If you get banned on a server for using any mods in this modpack I am not responsible.

💻| Installation

This modpack is a modrinth exclusive (for now) so here are a couple ways of installing it.

Download from the modrinth app.
Use a Modrinth Pack to Zip converter
Use and external Modpack Loader.

🧮| Versions

A forge or quilt version will not be coming out at any point however I do plan on uploading new versions in the near future, keep in mind that is not a promise and this pack may not be updated. If this pack is updated I will not backport it, I will keep the updates 1.20+.

Frequently Asked Questions

Flight Client server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Flight Client server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to Flight Client without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Flight Client server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
