A 35 mm rocket fin is good enough for the mega brushed motor. Make sure to get the name brand Rocket like the one below. There are a lot of copies that don’t move as much air. I don’t know if the stock 3S heat sink will work because it probably would cover the motor vents at the back of the can. So a basic powerhobby fan mount will work. I stick with the name brand powerhobby because the look a likes, which run a good bit cheaper, are made from softer metal and tend to strip out. I prefer the fan blowing directly on the motor. Heat sinks on rc motors impair cooling from what I’ve found.Would like info on motor heat sink and fan for 550 MEGA in SENTON 4x4 V3
a lot of products out there which ones are good
