RadioMaster's New Open Source Flybarless System - NEXUS!

RadioMaster is about to make the RC helicopter community very happy with their new NEXUS flybarless/flight control system.

The system is based on the Open Source RotorFlight software (a helicopter specific offshoot of BetaFLight). However, unlike the usual RotorFlight systems that you have know a great deal about PID tuning and helicopter physics to get working correctly, NEXUS is like all the other popular FBL systems on the market in that it has been PID tuned and tested in 250 to 700 size helicopters for over a year. Result - no beta testing and complicated tuning is required for the rest of us!

Rotorflight is a fantastic FBL platform, but it does require a high level of understanding to get working in your heli, not so with NEXUS!

This is HUGE and I predict it will change the landscape of the flybarless system market, the same way Open & Edge TX have changed the landscape of the computerized radio market.

The best part is the price - about $80 USD! Finally a high end, feature rich, fully CNC aluminum cased FBL system that is under the $100 mark.

Even if you don't plan on getting or using RadioMaster's NEXUS FBL system, there is no question it will send ripples though the market and make all the other big name FBL manufacturers take note and perhaps revaluate their pricing.

I can't wait to try out the NEXUS and haven't been this excited about any FBL system since the Bavarin Demon. Release date is early June 2024.

How To Check & Replace Ball Links Video

Quick video showing how to check RC Ball Links to determine if they need replacement. We will then replace these worn out RC helicopter links, making sure to get correct adjustment off the bench.

Quickly checking all your ball links should be a regular pre-flight session or post-flight session maintenance safety check, but I also go through every heli in the off-season to perform a more thorough inspection.

Loosening up ball links are a progressive issue so it's not like they will cause a sudden catastrophic in flight failure leading to a costly crash; however, it's best to replace them as soon as possible after noticing they are getting loose, especially if you fly hard.
