Doesn't really fit most 520 sized motors (too long). Definitely doesn't fit a Tekin 520 size motor without making contact with the soldering points. I had to put some foam between the heatsink and the contacts in order to prevent a short. Even then it barely fit between the contacts and the motor mount as it was.

Do not try to install this on a Tekno platform unless you are prepared to do some serious modification with a cutting wheel to make room for the center chassis brace.

After all of the modifications I finally got this installed and on the first run both fans died. I put some Tekin fans on it (much sturdier) and even with those the temps did not drop at all. Which isn't really surprising considering how little contact this heatsink makes with the motor since mine has a built-in heatsink. Would probably work better on a flat-sided motor with some thermal interface material, but probably still not worth it.

I bought these to help keep my motor cool after i was having heat issues. These fans and heatsink brought my temps down my 25f to 30f. Im not kidding, they make that big of a difference. Especially if you run them at 7.4v. They are like turbines, blow alot of air. You can also upgrade the fans to the yeah racing aluminum fans if you end up breaking these stock plastic fans. I catch huge air when bashing and i had 2 fans break, the aluminum ones make this setup up bulletproof. You can also add the yeah racing fan cage to help keep out debris. I love these so much i have them on 2 of my Teknos and my Arrma. BEST FAN/HEATSINK COMBO MONEY CAN BUY. BUY THEM YOU WONT REGRET IT!!!!!!!!!!

Very unbalanced fans. So big vibrations, that all model is vibrate too. Both fans send into trash.
