Hot Start is well known for their impressive work on their TBM 900 which many consider to be X-Plane 11’s best general aviation aircraft ever done. Now we are on the eve of the release of HotStart’s next project which is a simulation of the CL650 business jet. The goal is for lightning to strike twice and it looks like this may be one of the most detailed business jet simulations ever – but it does come at a price. Let’s have a look!
Features, features, features



Set to release on X-Aviation’s store tomorrow, the HotStart CL650 is simulating the Canadair/Bombardier Challenger 650 business jet. The aircraft is regarded as one of the most successful large sized business jets ever created with over 1,000 of the jets sold since production began in the early 1980s.
Hot Start for their part have aimed at a very high level with the simulation of this jet. The intention is to provide an experience that starts you not in the jet but in your FBO with interactions between you as the pilot and all of the pre-flight experiences leading up to fueling and then getting onboard the jet. You can evn ride in the de-icing truck.
The aircraft has a Pro Line 21 Advanced Suite with three independent FMC’s, screens, and more all simulated down to the pixel level (you can zoom in and see the pixels apparently). There are detailed physics models governing the operation of the aircraft, engine, and even the GPU. HotStart have also programmed visualizations so you can see just what the jet and its systems are doing. The same has been applied to the electrical system as well.
In short, this is an aircraft with an extreme amount of modeling detail. Despite all of that, Hot Start advertise that they have done a lot of work to ensure that the jet runs smoothly. System requirements have already been published:
- Operating Systems: MacOS 11+ (at least Big Sur), Windows 10+, and Linux.
- Minimum: Core i5 quad-core, 3.4 GHz + 16GB of RAM + GTX 970 graphics card (or equivalent, 4GB of VRAM)
- Recommended: Core i7, 8-core, 4.2 GHz (or Ryzen 7, 4.2 GHz) + GTX 2070 graphics card (or equivalent, 8GB of VRAM)
The price
This is where you may be bracing yourself if you haven’t already gone to look up the price. Offered through the X-Aviation store, the Hot Start Challenger CL650 for X-Plane 11 is going to be offered for the price of: $114.95.
Check it out in the X-Aviation store.

One of the aircraft developers, totoritko, has a YouTube and Twitch channel that has had several live streams showing off the aircraft and how to use some of its systems. The video is both instructional as well as a good showcase of what the jet can do.
There’s also a really well done behind the scenes video put together by Threshold that is done in the form of an interview looking at the CL650’s development process.
