Fly one of the stock helicopters in Microsoft Flight Simulator 2024, look down at the ground during a low pass, and something is missing. The turning rotor casts no shadow. Spin the rotor up from cold and the shadow is there for a while, then, once the disc reaches flying speed, it disappears for the rest of the flight. Helicopter pilots use that moving shadow to judge height and drift over the ground, so its absence has been one of the community’s more frequently raised complaints since launch. An open bug report on the official forums notes that almost every stock helicopter except the Bell 407 and the Huey is affected.
FWX Aviation has decided to fix it, and two other things besides. The small developer, run by real-world helicopter pilot Finn West, first appeared on the site back in April with an EC135 sound pack and a rotor haptic tool. It has since widened its focus from that single Eurocopter to helicopters across the simulator, and the result is three separate add-ons for MSFS 2024 that went on sale on a few days ago.
The shadow that goes missing
FWX tested this idea in public first. Earlier in the year it put out a free, EC135-only rotor shadow mod on flightsim.to, effectively a proof of concept, and the paid Rotor Shadow now carries the same work across seven types: the Airbus H125, H135 (EC135) and H225, the Guimbal Cabri G2, the Robinson R66, the Sikorsky S-64 Skycrane and the Boeing CH-47 Chinook, the last of those with both rotors covered.
The developer says the shadow keeps turning at full rotor speed and falls not only on the ground but on the fuselage and on whatever you happen to be flying over, from aprons to rooftops. Main rotor and tail rotor each cast their own shadow, and that shadow tilts with the aircraft through turns. FWX says the strength is fixed at full, with nothing to tune beyond an on/off switch and a per-helicopter profile. Any future stock helicopter without a shadow will be added at no cost, according to the developer.
Tuned helicopter flight dynamics
The second add-on is more ambitious. Called Flight Dynamics, it works on every helicopter in the sim and, in the developer’s description, reads live flight data together with the pilot’s own inputs at each instant, then feeds that back into how the aircraft behaves. FWX says the effect makes a machine breathe, drift and settle rather than sit in the air as though on rails, while staying controllable throughout. Speed, weight and attitude all change the feel, the developer says, because those are the numbers the effect is built from. Nine types arrive with a finished profile, among them the EC135, H125, H225, Bell 407, Cabri G2, R66, CH-47D Chinook, S-64 Skycrane and UH-1H Huey, and every other helicopter starts from a neutral default the user can shape and save under its own name.
FWX says this does not replace a flight model, it does not touch any flight model files, and it works on helicopters only. On how it sits against what is already available, the developer makes a strong claim, that no other add-on shapes helicopter behaviour from live flight data and stays adjustable while you fly. Established tools such as FSRealistic add their own set of helicopter effects, though they work differently from what FWX describes here. Finn West told us he is not aware of anything comparable and would want to hear about it if there is.
Per-blade feedback, hardware permitting
The third add-on, Rotor Blade Haptic, is the successor to the haptic tool FWX shipped in April. The idea is that ordinary haptics send one steady rumble, whereas a real rotor beats once per blade, so a two-bladed machine thumps twice per turn and a six-bladed one six times. The tool now follows the real rotor speed from the sim and matches the beat to the blade count of whatever you are flying, from the two-bladed R66 to the six-bladed Skycrane, with turbine and piston types both covered.
For this to work, you need a bass shaker, tactile transducer or ButtKicker connected as its own audio output. Without one there is nothing to feel, and the cockpit audio stays on your headset either way. That places it in the same territory as haptic packages such as SimHaptic.
All three, plus the earlier sound pack, are now set from a single in-sim panel FWX calls the Control Center, opened from the toolbar in flight. Each add-on has its own page, and changes take effect without a restart.
On pricing, the Rotor Shadow is €10.99 and Flight Dynamics is €20.99, with the Rotor Blade Haptic sold separately for less. FWX has also put together six bundle combinations, topped by a Universal bundle of the three universal add-ons at €25.99 and an All-in-One that folds in the sound pack at €27.49. For the first two weeks the three are exclusive to SimMarket, after which the developer plans to sell them through its own site as well.
