Default Hacker M-30 16 motor question

I have a Hacker 30-16M outrunner [sorry I got the numbers wrong above.] that is rated for 3s. It is a 1060KV motor. My question is this....can I prop down and run it on 4S? The motor runs a 10 to 11 inch prop on 3S but I would like to bump it up to 4S on something like a 9X6 or 8 inch prop if possible. I was wondering if the RPM's or higher voltage would be too much for it to handle. The motor resides in my Formosa II.

Thanks,
CTD

It should handle that just fine as long as you keep the amps in line.

Hi, a 4 to 5 pitch prop will work fine, 9" or 8" Dia. any more than that, and its going to be a rocket on 4 cells I cant fly my funtana 42" w/s with more than a 11x5 prop, the motor is a 3548 1000kv outrunner on 4 cells,its Fast, can only fly it at Half throttle, or i will rip the wings off of it and it takes off in less than 10 feet, straight up Take care, Chellie

I'll have to try a few props on it and see. I was kind of worried about exceeding the rating for the motors RPM. I don't have a tach to measure the RPM. I'll have to borrow one. More later.........

Hacker A30 Series
Select motor:
Select gearbox:

A30-16M







Designed for 25 to 35 oz. Parkflyers and 3D-Aerobatic models with 2-3 cell LiPoly batteries










Idle Current:1.6 amps
Operating Current:22 amps
Peak Current: 33 amps
Peak Watts:350
Resistance:0.038
RPM / V:1060
Battery:3 LiPo
Shaft Diameter:5.0mm
Shaft Diameter w/GBn/a
Weight104g (3.7oz)
Weight w/GBn/a








This is from Hackers website. They dont state a max RPM for this motor. I tried a 7X5 prop and it pulled only 17 AMPS at about 280 Watts. I don't have a 8 inch prop to test and my 9X6 was way too high on AMPs it jumped up to beyond 44 AMPs even before I got to WOT so I backed off. I don't want to smoke this motor they aren't exactly cheep motors.

your motor is only about 1000 kv/rpm you wont hurt anything, there are motors out there that are 5200kv/rpm the bearings will take the rpm, no problem there, just keep the amps with in reason, and you will be fine, hope that helps, Chellie

your rpm with a 4 cell will be about 14,840 14v x1060kv =14,840 thats nothing

I had a 5300kv motor on 14v 14V X 5300kv = 74,200 rpm LOL

Lots of guys are running small cheep outrunners in EDF applications at upwards of 50K rpm.

Chellie's right. The Hacker will only be seeing about 17K max with no load at all, so it will be fine

Balance the prop very well though. The higher the rpm the more important that becomes.

Thanks Chellie and Larry. I'll have to get some 8 inch props to test. The 7X5 just dont cut it in this application.

One other point - DO NOT use a slow-fly type prop. Your rpms will be way to hi for safety. Use a regular APC-E prop or some other brand that can handle the hi rpms without flying apart. Thats probably more excitement than you need
