Description
The Bell 429 NextGen is a complete overhaul of the freeware jXt Simulations Bell 429, rebuilt using real-world documentation from Bell, EASA, and Transport Canada.
The goal: maximum realism – flight dynamics, PW207D1 engines, NR/NG/ITT limitations, torque, and performance have all been fine-tuned according to official manuals and pilot feedback.
IMPORTANT: jXt Simulations is the creator of the B429, compatible with MSFS. We would like to thank them for giving us permission to publish this mod and for their amazing work on the B429.
Flight Model
- MTOW 7,500 lb, NR nominal 395 RPM, VNE 155 KIAS, cruise 150 KTAS.
- Hover IGE/OGE, coning and inertia tuned to match Bell data.
- 610 shp max continuous, 621 shp 5-min takeoff, realistic torque and ITT.
- Correct green / yellow / red ranges for ITT, torque, NR, fuel, oil – all based on Bell & P&WC documentation.
- Dynamic vibrations during startup, hover, takeoff/landing, and in flight.
Systems.cfg has been modified as well
Installation
1) ⚠️The jXt Simulation B429 is mendatory and you have to have the latest version ⚠️available here -> B429 by jXt Simulations
2) Simply unzip the folder provided in "Community"
Question: I'm new on MSFS world, how to be sure that the mod is working
Answer: You can't, there is no sticker or istinctive visual features. However, the colors of the cockpit gauges (yellow, green, red) have been changed. So you can compare the instruments before and after installing the mod.
❓ FAQ – How MSFS handles mods
Q: Why doesn’t your mod include all the files?
A: Because it doesn’t need to. In MSFS, a mod only contains the files that are modified. The simulator automatically loads the base B429 package first, then replaces the matching files with the ones from the mod.
Q: Why is the folder structure important?
A: The mod must keep the same internal folder structure as the original aircraft, otherwise MSFS won’t know which files to replace. That’s why you see folders like SimObjects/Airplanes/B429 inside the mod.
Q: Does this mean my original B429 is changed?
A: No. The base B429 remains intact. The mod sits in your Community folder and only overrides certain files during loading. If you remove the mod, MSFS will go back to the original B429 automatically.
Q: Do I need to copy/rename anything?
A: No. Just drop the mod folder into Community. No renaming, no overwriting.
✅ Notes
- Compatible with MSFS 2020 and 2024.

More Information
Version History
Version 1.1.1 – Flight Model & Trim Improvements - Fixed longitudinal trim authority: increased nose-down trim so the helicopter now maintains fast, level flight without constant forward cyclic pressure. . Adjusted main rotor neutral: lowered static_pitch_angle and shifted cyclic_pitch_centre forward to reduce nose-up tendency at high torque levels. - Improved pitch responsiveness: fine-tuned cyclic_pitch_control_scalar for smoother and more realistic control feel. - Stabilizer tuning: reduced horizontal stabilizer incidence for a more balanced cruise attitude above 100 KIAS. - Overall effect: less pilot workload in cruise, more natural trim behavior, and closer alignment with real Bell 429 handling feedback

Could the error be with the Bell 429? I couldn't unzip it into the community folder, but had to copy a subfolder into it so that it would be displayed.
Many thanks and best regards.

So ir's like this: ZIP -> UNZIP -> A folder. Open this folder and the content has to be copy and past directly in the "community" folder.
This is a bit of a rule for all add-ons: it's better to unzip them next to them and then move the folder that's in the main folder.

I really hope this continues to be developed (either by yourselves or both JXT and yourselves). This is a great foundation to build a really advanced heli with a few more of the native cockpit screens and autopilot.
I would certainly pay good money for this... every now and then a developer comes along that seems to really be passionate and to care and that is worth holding onto.
I am enjoying this a lot so far.

Already on X-Plane the helicopter was incredible, and the flight dynamics on MSFS are really enjoyable!
We’re in contact with jXt Simulations, of course, but we don’t know yet if they will release another update (though we think they probably will). As for us, we’re not going to stop development. We’re working on a co-pilot, but we need to be careful because if we touch the 3D model too much, it could cause issues — since the 3D model was originally created by jXt Simulations.
Honestly, we don’t really care about popularity. Our goal is simply to create good add-ons, good mods. That’s how the project started: “the MSFS B407 is terrible → let’s fix it and release it for free, for the community.” So jXt Simulations knows that we share our files without any copyright problems — the goal is really to make a free helicopter that outclasses some payware models.
So yes, we can guarantee that there will be updates — either from us, from jXt, or from both. But development will definitely continue.
One last point: we're waiting to know more about MSFS 2024 SU3. It's complicated to explain, but we have to create external softwares, to change the flight model, so we have to create it. So we're thinking that we might focus solely on MSFS 2020.
This is a bit of a dilemma for us: continue coding with .cfg files or if we say to ourselves "ok these files will probably no longer be accessible. So we might as well create external scripts and tools (in fact this is what those who build the paid helicopters do )

FS2024 must be a nightmare for developers... there are so many variables to contend with, not least the amount of SUs they are releasing. I only use 2020 at the moment as it is reliable and does exactly what I want. So if I was being selfish, I would encourage you "stay with 2020 for now" :)

This is a very good idea but also a very good question. To simplify: yes it is possible but under several conditions. The 3D model must contain specific points to "add" the effect on it. But these points are not mandatory, the developer can decide to not creat them. So if these points exist (we will check), the answer is yes, it is rather simple and we can do it. If these points do not exist -> it is much more complicated. Already because we have to modify the 3D model (not sure that jXt is ok with that) and in addition: we are not 3D artists, it is not our specialty (for the moment) but technically we can add these points without going through Blender. Last limitation: MSFS 2024. With MSFS 2020 files, it is very easy to find the right file to modify. For MSFS 2024: it is much more complicated. So even if it's theoretically possible for MSFS 2020, we can't really know if it will be compatible with MSFS 2024 SU3. We'll check and let you know!

B429 JXT from Flightsim.to V1 Aug 25 does not work with add-on liveries and the Next Gen mod doesn't either.
B429 JXT from Discord v0.9.7beta May24 works with add on liveries and is listed here as a version that works with the Next Gen Mod but I still can't get it to override the JXT version.
Is it possible to list the required version numbers for a successful install?
9 months ago
We’ve tested the NextGen mod several times and it does correctly override the latest JXT release from Flightsim.to (gauges, weights, liveries all update as expected). The issues you mention usually happen when:
An older beta version of the B429 JXT (from Discord, e.g. v0.9.7) is still in the Community folder.
Or when multiple B429 packages are installed at the same time, which can cause MSFS to load the wrong one.
👉 To be sure it works:
Keep only the Flightsim.to JXT version (latest stable).
Place the B429-NextGen folder next to it in Community.
Double-check that no other JXT or liveries are conflicting.
We’ll also publish a list of supported version numbers so it’s crystal clear which base release the mod is built for.
Thanks again for your input — it helps us improve the documentation for everyone 🚁

That means there’s a huge amount of expectation from the community.
Our first changes won’t be spectacular — but because expectations are so high, people could quickly end up being very disappointed if the mod doesn’t radically change the flight experience. In that context, making only small adjustments could actually make us unpopular, with comments like:
“You changed the flight model but I can barely see any difference, this is useless, I’m giving it one star.”
And the problem is that this kind of feedback has a direct impact on our other add-ons as well.
It’s a bit sad, but that’s the reality of being a developer: the community can sometimes be very harsh — even when it comes to freeware. And that can devalue the work we’ve put into our other projects.
So we need to think carefully about how to modify this helicopter in a way that makes the community clearly notice the difference between before and after, and feel satisfied flying it — even if it’s freeware.
