For the price these are a no-brainer. I picked up two to run on my arrma speed Buggy in a pinch and they ran great. Move plenty of air and lasted through several hi speed flips and even an 88mph cartwheel for a few hundred feet. Unfortunately I had a Nasty +80 airborne "adventure" into a concrete berm that finally totalled the fans and half the car. I would highly recommend

Probably the strongest fan for the price. Will hover by itself type of strong. But the fan will pop out if you land upside down hard, but it could just be me putting the shield at the bottom instead of the top but for reals this fan is strong. (for the price) I haven’t tested high end expensive fans yet :)

I would love to find a reasonable priced fan but unfortunately I don’t think this one is it. Missing multiple blades after it’s first qualifier, even with the included screen. Clean as a whistle inside, had to self destruct.

I bought 2 and both immediately failed. Did not get 2 batteries out of either.

well will have to say? for the General Conditions? i think will work very good!!
however? for "Me" it did not hold up in the rigors of racing? and the fan blades had broken,
more than likley could have been placement? but since i am using the Kyosho MP10T and TKI2 series cars
i run the Kyosho Placment adaptor for Fans, could have been the Wiring running under it? but in end it had broken?
i think in general? should hold up great in most applications, in 1/8 scale? it could break in some conditions?
since i have gotten a all "Aluminum" custom one Prototype, (Alloy fan blade and outer case) and have had no problems?
so in some cases for 1/8 scale? may want to look around? but in general this one works very well!! held up for a day of Qualifiers and Mains, but the fan blade itself one fan blade broke off and other had Cracked and chipped,
so in 1/8 scale cars can be pretty bumpy!
i will say in Fairness! there was no "Cover on the Top" my purchase? it did not have one in package? and had to use for that day, like what may see on most ESC's for example? and since they spin at a very High rate!! a Small Pebble could have been caught in it? so as i said in general it was good!! but would get a Cover for it?
as this would help greatly i feel and may have not ever Broken?, off road 1/8 scale can be very Unpredictable!!
hope this can be of some assistance?
