When on in 5 minutes onto my Typhon 6STLR. It is a little snug. Very easy to get on but you will need to remove the motor. Will need to position the heatsink so it clears the motor mount by the pinion. You can figure it out how you want to position it from there. The clip was really easy once you figure out how to do it and what the hole is for. Attach one side of the clip to the heatsink fin and with a 2.5mm or 3mm hex wrench/allen key, put it in the hole and pry the other side up and over the fin on the other side.Easy.

Very irritated at this product. Not sure why they say it fits, when it doesnt. I would literally have to take my grinder with a metal cut off wheel, and cut off about 2mm to make this fit in motor mount. Waited a week to get this factory heat sink, only to find it doesnt fit. It took me an hour just to get it on the motor. DO NOT BUT THIS

As another reviewer stated you will need to notch off a small part in order for this to fit. Other then that its seems nice, I will up date if it doesn’t cool well.

This works like it should especially when combined with a fan. Definitely lowered the motor temps on a Keaton 6s

It takes a little elbow grease to fit this on, but once it is on you know it will stay on because it was designed specifically on the Spektrum Firma 4074 2050Kv Brushless Motor.Attach the clip to the underside of the heat sink, and then squeeze the heat sink over the motor with firm but gentle pressure. Once you install a fan you will notice how much cooler your motor will run.

Very tight fit which is great for the heat transfer but was slightly tricky to get on. Seen several other designs and still choose the factory heat sink. Married up nicely with a hyperflow fan using a printed adapter.

I installed this on my Arrma Notorious 6S V5. It took some time to install as this is a very tight fit, but definitely reduces the motor heat by several degrees after strong runs. It did want I was expecting. Nice upgrade. I also purchased for my Arrma Kraton 6S V5.

With slight modification on the plastic center gearing cover it fits perfectly. But you have to shorten one of the pegs as shown in the photo. Other than that it's perfect. Clip holds on well for now.
