After replacing bearings motor gives about 3 kg. thrust on 90mm 5 blade EDF, 6S and 100A ESC. Good out-runner motor for 90 mm. EDF, but not of the best quality bearings.Have just bench tested this motor. 6 blade, pulled 74A and 2.6kg. Motor did come off a little hot, but for this price it is a bargain. The motor came with good balance also.Came in a box, looks nice and ood machined. I use it on a 75mm EDF at 6S and works good. Unfortunately I do not have measure-equipment, but I am happy with the power of that motor.Durable with extreme performance even if overloaded ... see the web for evidence ... highly recommendedATTENZIONE NON SO SO DIEPENDE DAL MIO MOTORE CHE NON FUNZIONA, MA CON UNA BATTERIA 6 CELLE E VENTOLA 90mm 7 PALE SI BLOCCA.
PROVATO CON 5 CELLE E STESSA VENTOLA 1400W.
Ciao a uttiA top quality motor, can't fault mine and a super price for what it is. Mine is on a 90mm 7 blade fan and it has impressive performance with very smooth running giving a good jet like sound. This relies on getting a balanced fan unit of course, A five cell Li Po is used.I gave it 5 crowns even tho it came with out motor screws which you really need because I don't know what strange thread pattern it is. I ended up re tapping mine to 4mm and its ok now. This motor makes great power and seems pretty well balanced. Ive put it in a flyfly 90mm 6 blade fan and mounted it on the back of a Multiplex Funjet. Using a Redbrick 125 esc with a 6S 2600 40c batt. Estimated speed is about 120 mph maybe a little more. Great little motor!This is very good motor. i use this with haoye 3.5 inches 7 blades in my homemade jet on 5S and it has 2.4 kgr thrust with intake ring . 86 Ampere at full throtlle. Thank you HK!!
Good motor for the price, make sure you set your ESC timings for mid range, I'm using the HK red brick 100 amp ESC and it defaults to inrunner 1 degree. I changed that to outrunner 7 degree and 8 KHz PWM 24 volts 1750 watts static with a 6 blade fan.Con edf haeoye 7blade f 84a max e 1700watt a 6s 4000mah zippy 40c. Spinta 2,4 kg. su Mirage flyfly peso totale 2,0kg. un p caldo alla fine ma siamo in estate.
With edf haeoye 7blade ago 84th 1700watt max and a zippy 6s 4000mAh 40c. Thrust 2.4 kg. Mirage flyfly total weight of 2.0 kg. a little hot at the end but we are in summer.
