Works very well to reduce motor temperatures. However, it will only fit on a 550 size motor and NOT a 540 size motor like a traxxas VXL.
Bought for Tekin Pro4 HD 4300 in a Tekno 410.3. The diameter is fine but the length is an issue. I trimmed off somewhere around 1/8" from each side. I'm using a large zip tie to prevent the heat sink from sliding into the motor power posts. It's a tight fit in the 410.3. Smaller pinions will require shaving the risers on the side to clearance the middle support brace, or remove the brace. Overall I think this is a good product although I didn't expect it to (possibly) be specifically and only for Hobbywing motors. At least I hope that it would require no modifications to fit on Hobbywing's own products. I haven't had the chance to use it yet but I expect it to perform adequately.
Bought this for my xerun sctpro combo. read the description first it is a huge heat sink and fan! I will fit the old style xerun with the long can motor.... Not the new style! It is a nicely made part and the fan moves a lot of air. I am impressed with the quality of the product but feel the description should have mentioned that it would not fit the new style motors. The description reads as follows "This is an optional Hobbywing C1 Motor Heatsink and Fan Combo. This aluminum housing heatsink will fit any motor with a diameter of 36mm and will help dissipate heat away from the motor." With that to my fault it does say "Specifications: Voltage: 5V Size: 48 x 48 x 16mm Heat Sink Diameter: 36 x 55mm" Who to blame Hobbywing, Amainhobbies, or me. I guess me...
Cools well, went with a different fan though.Gave it to a friend who uses it on an Arma.
Price and quality are good. Requires modification (grinding) to fit a Slash 4x4 (not lcg chassis) if you're looking at that application.
Reviewers generally agree the heatsink and fan cool motors effectively and that the build quality is good. The main recurring problem is fit: many reviewers report the heatsink is too long for common 540 and 550 size motors, Hobbywing 3660 motors, and some chassis such as Slash 4x4 and Losi Baja Rey, and most who used it on those applications had to cut, grind or trim it. Several noted the product description suggested broader compatibility than they found, and one reviewer said it was not suitable for 4x4 or 1/10 2WD setups without modification. Some reviewers used only the fan, and one reported the fan alone worked well. Overall, reviewers describe it as effective when it fits, but fit commonly requires modification.
