Awesome little fan. Used 2 of them on a twin fan mount in a TA05 IFS-R on a hot Aussie day. The fans helped keep the car competitive to a winning position in an ultra competitive 8 minute final 540 class. While others were slowing due to overheating the car kept up consistent race lap times right to the end. I've tried other fans and lap times slowed usually on the last couple of laps. Not this time. Motor finished with plenty in reserve and will easily race again. Good investment. Race winner. Made my son very happy.
