Default Power Up 180 Sport high amps?

Looking for a little help. I sent a customer support request on the HeadsUpRC new site, but haven't got a response after several days. Perhaps a site problem?

Anyway, I just received a Power Up 180 Sport outrunner from them, and it's pulling too many amps compared to their specs on their site. And getting warm.

With that motor, I'm using a GWS5043 prop, a HURC 7 amp ESC, and 2s 500mah 35c battery. According to their chart, it should be pulling 2.5A, but I'm reading 5.6A! They rate the motor at 3.5A max for 30 seconds, so I only ran it for a moment to get the reading.

So I'm wondering, is their chart mis-printed, faulty motor, anything I did? I'm just looking for a power system for my Zeke's Park Scale Models Mini Drake. It calls for a "10g brushless outrunner w/5x4.3 prop and a 6A esc". I thought this would be the perfect motor.

I'm never gonna get this electron thing...

Oh, and I don't know if this means anything, but the power-on beeps from the motor are barely audible, which is the only unusual thing I can identify. Is that a hint?

Well, I just checked my e-mail and got a response from them. They say they've switched vendors and had some issues including motors not performing to specs, so they'll be switching back to their old supplier, and offered me a refund or replacement if necessary.

Some motor / ESC combo's will give very loud beeps, while some others will be so soft you almost can't hear them.

I don't know what causes the difference.

Hope you get your motor figured out. Maybe the one you received is wound for a higher KV, which would need a smaller prop. Try running the motor without a prop, and see what the current is.

OK, but how do you get KV from that?

You cant... you have to measure input voltage and no-load RPM to get (an approximation of) Kv.

Motor beeps are an indication of ..... not much. They vary depending on the motor and ESC combo.

The winding quality of most inexpensive Chinese motors is erratic. Having a higher KV is not unusual, in fact I'd say it's more common than coming in at spec, one of the reasons a wattmeter is a good idea.

I'd say you can prop down, or go for a different motor.
Props in this size and motors of this size/kv are pretty particular. You may have to try several to get results you want.

Thanks guys. I tried a GWS4040, and even that was over amping it... Poking around I noticed on the site where I bought the kit this motor was destined for, that they also sell motors, and probably one that was meant for this plane... (Slaps forehead) Hopefully that'll be the one.

Hi Mech Let me turn you on to a great little motor, that can be used for a lot of applications, its a 1800KV mini motor, but this motor does not think its a mini motor you can use a 3 cell 1500mah lipo with a 7x6 APC prop and power park fliers with it or mini planes with 2 cells, it loves to be over amped, use a 30 amp ESC with it on larger planes, i use them at 22 amp all day long and they love it, this motor has thick winding on it, Berry uses them on his multible engine planes here on Wattflyers, and they are only about $6.00 each, I have a lot of these motors and have not burned any out yet here is a video from KOSH with one of these motors in his scratch built plane, use them with a small esc and 2 cell on small planes or a big esc with 3 cells on larger planes, this is one of those use for just about any plane motors

Kosh is using a 7x6 APC prop on 3 cells in this video

These motors are far more $$$$, but the 8 motors I've got from this supplier work and work well. Hacker motor specs are fairly accurate. You can run them at their specified power levels without issue. (My motors range from an A30, to a pair of 2500-3000 watt A60 units)

https://www.aero-model.com/8_81/Moto...-S-Series.html

Last fall I was working with a club member with a giant scale jet with two ducted fans. The fan units were not cheap, over $500 each. Their specs indicated they would pull 85 Amps on a 6 cell LiPo. I actually measured 190 Amps each! Not even close.

Thanks gals & guys for the tips. I went ahead and ordered the motor at their site already. I bookmarked your suggestions though for future use, especially in case that one doesn't even work out. (Though at this point, I'm starting to check out some rubber bands...)

LOLOL
Back in the mid 1980's I actually investigated the possibility of using rubber powered propellers to launch a two meter sailplane. Turned out, rubber power was not even close to the capability of even a brush type geared motor back then.

I've burned up at least two of the PowerUp 180 motors on the recommended prop and a friend of mine has burned up at least as many. It has been at least a year since then. I'm a huge fan of HeadsUpRC, but I stay away from the 180, now.

All of my landings are three point landings if you count the spinner, too

Out of curiosity, how much do these motors weigh? And how many watts were you running through them?

IMHO, anything much over 100 watts per ounce of motor weight might be pushing it, especially with some of the available low cost motors on the market.

I ran across one that claimed 180 watts per ounce after running the numbers. Motocalc.com suggested at that power level this motor would be running over 500 degrees F on its motor windings.

Follow-up: I got the motor from Zeke's, soldered the connectors and ran her up with the 5x4.3, it pulled 3.6A. The funny part: I went back to Zeke's site, and they no longer list the motor, so I can't see the specs listed, and it came with no paperwork! (Insert slapping forehead smilie here...) No biggie, I guess it'll be OK. At least it's not like 6 amps or something! I'll go with it. Now I can build the nacelle and move along. Thanks for the help.
