🚁 Flybarless
A modern rotor head design that uses an electronic gyro for stabilization instead of a mechanical flybar — lighter and more precise.
What it actually does
Flybarless helicopters replace the mechanical flybar with an electronic unit that reads the model's movement and corrects the swashplate directly. The result is a simpler, lighter, more responsive head with less drag and less mechanical maintenance.
In practice
The flybarless unit needs correct setup: swashplate levelling, servo direction, cyclic and tail gain. It is now the standard on collective-pitch helicopters, and the tuning has become much more approachable than it was.
Worth knowing
Mount the unit exactly as its manual specifies for orientation and vibration isolation. A flybarless unit fighting vibration behaves like a badly tuned one, and no amount of gain adjustment fixes it.

RC Crash Crew remembers your RC so you don't have to. Every run, every battery cycle, every breakage and every fix — kept with the rig it happened to, for as long as you own it. No cost, no advert, no catch.
🏎️ Your garage — the part that works on day one
Build each rig properly: what motor, what ESC, what gearing, what tires. Then keep its whole history in one place.
- Run log — where, how long, how it went
- Battery health — cycles, puffing, when to retire it
- Component hours — what is worn out before it fails
- Setup sheets you can copy between rigs
- Radios and model memory
- Photos, kept with the rig

Straight with you: the site is new and the crew is small. The tools, the guides, the map and the 505 run spots are all here and working today — the people are what is still missing. If you want a garage that remembers everything, it works from your first run. If you want a busy forum, come back later, or be one of the reasons it gets busy.
