GrabCAD part slowing down my assembly in SOLIDWORKS

I am building a drone in SOLIDWORKS and I am using motors which i downloaded from GrabCAD. Whenever I insert the motors to the assembly, it becomes significantly slow. The assembly is only about 79 parts, so it's not large at all. Anyone might know what the issue is? Please let me know. Here is the link for the motor if that might help: EMAX RS2205-S 2300kv BRUSHLESS MOTOR

I am using SOLIDWORKS 2016 edu version.

System specs:

OS: Windows 10

Processor: Intel Core i7 6700K 4.00 GHz

Graphics Card: NVIDIA - Founders Edition GeForce GTX 1080 8GB GDDR5X PCI Express 3.0 Graphics Card

RAM: 16GB 2 x 8GB DDR4-2400 PC4-19200 CL16 SR Dual Channel Desktop Memory

SOLIDWORKS just crashing is most commonly caused by running out of memory, or swap space on the hard drive.
Troubleshooting it can be difficult, but I'd start by trying to do a very simple motion study of two blocks or something equally non-challenging.
Also consider making those "simplified" configurations of parts and assemblies I mentioned above. The parts should have all "extra" cosmetic features removed. Fillets, text, graphics, helical threads... Make the parts as simple as possible.

You didn't even press the like button for the model yet... That has to be a requirement before getting help on downloaded models :)

It is a great model, but there are a ton of complex features and sketches which will slow down a system.
- You could/should scroll through the models and suppress any details you don't need.
- You could also save the assmebly off as a "dumb solid" if no edits are needed.
- Loading the model(s) as lightweight can be handy, but I don't use that option much.
- Tools-Defeature can help to remove some complexity, but I usually just make a new part/assembly configuration with features suppressed.
- Also, go under tools-options-document properties-image quality and move the slider a bit to the left for the shaded mode rendering.
- Your graphics card is most likely not on the "supported list". It has been a long time since I used a geforce card, but I found they could handle one, or several parts at once, but there was a threshold which made things crawl if it was exceeded.

Don't forget to go back and press the like button. It took hours to make that model, it would be seconds to show appreciation for it.
