Tough to get on, it fit my armma kraton and notorious great. Definitely worth the price

Big enough to fit 2 50mm fans. Gotta keep that motor cool

Had to Dremel to fit my 6s exb

Now I can run my limitless until the batteries are dead without overheating the motor. I do have the fan installed also.

Purchased for my Infraction Mega getting the Brushless ESC from my Vendetta and a Firma 6500kv before running the RC. This was a good fit. No issues with the part or shipping.The low rating is for Product Support on the Vendetta!The Issue –On initial run the RC wouldn't hold a line. This is on 3s with the stock gears. After initial run I found the rt rear tire had rubbed the body.The Struggle -After some investigation I spun the tire on a balancer and it had an rolling/out of round issue. Contacted Product Support and was told tires are a ‘wear item’. I can accept that, however during the trouble shooting with Product Support the agent asked for a 'video of the axles themselves spinning without the wheels on so we can determine that it is in fact the axles'. After sending the video, Product Support’s response was ‘Thank you for the video. That is normal play in the axles’ and ‘That is a normal amount of play in the axles from the factory’. So normal play in an axle that allows the tire to rub the body and RC not hold a line, stops support. Advertised as a 'Speed Basher', I could not ever try to send an 6 pound out of control missile at the advertised speed of 70 mph anywhere for *safety. *safety opinion… always slow test before you try to do speed runs with any RCThe Proposed Solution -To send the RC to the service center. (Shipping time to, 5 day SLA and then shipping time back)(Not sure if it would be back in time for some Christmas ‘Speed Bashing with the kiddo’s)The experiences -I've been in the hobby for about 8yrs, this is the first year to venture away from Traxxas (14 total). I even own some WLToys (4 total)…lol and the 2 issues were resolved with credit to replace the parts Product Support will…As soon as support closes if your emailing them they just shut down without any closure… leaving you guessing if they are in need of emergency help or a burger. A nice touch would be to inform the customer you have been emailing with all afternoon that support is closing and someone will contact you before you need emergency help or you having to make contact back into Product Support. *Generate a system email to all active issue customers of the pending closure of Product Support and an auto reply once closed.If you are chatting with Product Support online they will ghost the chat leaving you to restart with a new agent in the chat. Almost like faking a network issue to close the session on their side and all the customer can see in the chat is the Agent has left the chat. Wait but this is generally after they have greeted you and ask for a moment to review the chat session. *Solution – only the customer can release an agent from a chat. Even if there is a network issue the agent must rejoin the session.Being told by Product Support to use higher quality tools. Sadly the tools I was using were purchased from Horizon Hobby.I had an issue with my Drag Limitless. My ask of HH/Arrma was to just replace 1 part. It took almost 3 weeks. I replaced the part myself ~$11 and in the end HH/Arrma product support replaced the part. My speed Limitless had no issues. I get it it's a hobby but it matters when a single RC is ~$400 per RC.

This heatsink is for the Kraton 8s and takes a 50mm fan. Hobbywing makes one. I bought to go on a Hobbystar 4585 which is a weird size can. I had trouble finding a heatsink for it but this looks like it will work.
