I use mine for a SUPER fast zagi wing! 5*5 with 70-80 amp ESC 3s lipo! It puts out insane thrust with something like 220mph Pitch speed. I used a drill press and put some vent holes as there isn't any stock.

hi,can you tell me what brushless motor,esc and lipo cell to replace a 540 brush motor and 7.2v nicad in my rc buggy.
thanks!
 CHOL 37 points
Hi, the battery you are searching for is not here on this site has i searched for it, a battery that is 100x bette than the nicd is a 3 cell lipo battery it is very powereful and can make your buggy 5x faster then it used to be, the bad thing is you have to buy a special balance charge at least $18.00 from this site, here is the www.link The speed control That I recommend is a hobby king 60AMP speed control here is the link http:

would this motor fit in my stryker? if so i wonder if it would swing a 5.5 prop? any specs on this anyone?
 EUI JIN 5 points
I am using this on my pylon racer(Sunracer)
APC 4.1x4.1 would give it about 70A, 750w with fresh 3s batteries. Tried up to 4.5x4.1 around 70~80A 800w motor gets pretty hot but had many flights with no trouble. I think this is the best setup for 400class pylon racer or for speedy racers!!!

arichards1969, if yours unscrews it is different to mine! the rear cap just prises off, it is glued! shaft is very soft, it cannot be removed from magnet rotor as it is bonded and knurled! the rotor breaks when attempted! give this motor a miss!!!
RattlerinAus  9 points - 11/28/2009

Which speed controller is suitable for this motor with EDF 2.56inch for 1m. wingspan jet.
 WireD 51 points
Take a 60 or better, cause they have the same dimesions 80 A Turingy ESC. with an 80 A the esc will not get so hot

The motor seems pretty well made, I wish it was labeled in some way though. I used a Dremel to engrave the model and kv on the case. As others have said, the 9S motor is 4300kv. The 8S by this manufacturer is the 4900kv.

I tried this in the 2.68" EDF unit. I wouldn't recommend this motor for this fan myself, unless you have batteries to back it up. In a bench test, this set up drew almost 60A on a 3S pack! My pack held 10V at that draw, so the fan absorbed about 600W at about 40000rpm. At that, it gave an eflux of about 135mph and just over 1000g of thrust.

I would recommend a lower kv motor for this fan, but this motor really packs a punch!

This motor worked in a L 39 with UH 2,5"EDF and pushed the foami to the limits.10N trust/930gr weight - take off after 15m with following vertical climb. Thats the way jet pilots like.

This great little motor powered my 2,5" UH EDF. But attencion by perfect balanced rotor. The real KV is 4300/V.
This is an great upgrade set for the UH L 39, the plane take off after 30/40m from gras!! Following verticle klimb and have a thrust ~ 12N.
Great stuff for penny!
