UNDEAD BATTERY
TRYP FPV
Five authored maps plus scanned real locations, built around a race mode and a global leaderboard.
01 Overview
The visually heaviest of the FPV simulators and the one built on Unreal, currently 5.7.4. Visuals are its most-praised aspect, named in about 28 percent of its reviews, and several of the most-voted negative reviews concede them before listing their complaints. The environments are five large authored maps plus a separate library of real locations captured by scanning.
Its control law is unusually well sourced. UNDEAD BATTERY state that the Betaflight team assisted with the direct implementation of Betaflight's own PID algorithms and source code. The aerodynamics are credited to ONERA data alongside beta-tester feedback; the developers have never used the words validated, verified or certified about that relationship, and ONERA is not mentioned on the store page at all.
It has been in Early Access since June 2022, and the store's own Early Access answer still reads that the game will remain in Early Access throughout 2025, a window that has now passed. Development is active: a large June 2026 update reworked the aerodynamics, added battery simulation with voltage sag and propeller damage, and rebuilt several environments.
02 Pros and cons
Pros
- Visuals are its most-praised aspect by a wide margin, and even critical reviewers tend to concede them
- The control law is sourced from Betaflight's own PID code with the Betaflight team's stated assistance, which is a stronger provenance claim than a description
- A growing library of real locations captured by scanning, which pilots single out for long range and for recognising places they have flown
- Five large authored maps alongside the scanned locations, among them Megabando, Ruedersdorf and the Eiffel Tower
- Betaflight-style switch management, so arm, angle, acro and horizon sit where they would on a real radio
- An optional setting simulates video-link latency, about 5 ms for analogue and 25 to 30 ms for digital, with selectable camera lens models beside it
- Built on Unreal and kept current, 4.27 at launch through 5.7.4 in June 2026
- Race mode against a global leaderboard, raced asynchronously rather than live
- Engine and physics changes are published in detail in the patch notes
- Active development, including a substantial June 2026 aerodynamics and battery rework
Cons
- The flight model is the most contested part of the sim and draws most of its negative reviews, with floatiness the most-named specific physics complaint at roughly 9 percent of its negative reviews, still appearing in reviews from mid 2026
- The physics reworks themselves have drawn complaints from existing pilots, including some high-hour ones who preferred an earlier build
- Performance is a real cost of the visuals and appears in about 10 percent of negative reviews
- Content is all developer-made: no track editor and no Steam Workshop, with a map editor listed as upcoming, and UNDEAD BATTERY list tinywhoops, larger drones and more components as still to come
- Still in Early Access, listed since June 2022 with the store's own stated window now passed, and live multiplayer is a beta that has run and closed rather than a shipped feature
03 The numbers
- 01Price
- One-off purchase. Still in Early Access on 11 September 2026, listed since 30 June 2022. Check the store for today's price.
- 02Physics model
- Per-component aerodynamics on Unreal, 4.27 at launch through 5.7.4 in June 2026. The control law is sourced rather than described: UNDEAD BATTERY state the Betaflight team assisted with the direct implementation of Betaflight's own PID algorithms and source code. A June 2026 rework added per-prop propwash and vortex ring behaviour and prop grip from polar curves, both marked work in progress, alongside LiPo battery simulation with voltage sag and propeller damage on impact.
- 03Controller support
- An RC transmitter is recommended. Betaflight-style switch management maps arm, angle, acro and horizon as they would sit on a real radio. An optional setting simulates video-link latency, about 5 ms for analogue and 25 to 30 ms for digital, alongside selectable FPV camera lens models.
- 04Multiplayer
- The shipped build is single-player with asynchronous racing against a global leaderboard. A live multiplayer beta has run and the developers' patch notes say it is re-opening. No lobby capacity is published.
- 05Track library
- Five large authored maps, plus a separate and growing library of real locations captured by scanning, which includes Megabando, Ruedersdorf, the Eiffel Tower and an iron mine. There is no track editor and no Steam Workshop, so all content is developer-made; a map editor is listed as an upcoming feature.
- 06Drone customisation
- Frames, propellers, LiPo batteries and cameras, plus rates and camera angle. Alongside the detailed physics parameters there is a simplified set of sliders for pilots who would rather not use them, which has grown past its original seven with propwash and ground-effect additions.
04 System requirements
- Processor
