Schultz Repair time

[RandyatBBY]

Are you all saying never to leave a lipo plugged in with the transmitter off? I never heard that before. I know not to leave them plugged in to an esc because the esc is drawing current all the time and will drain the battery below a recovery point but never heard the other. Is this true of all ESC's or some sort of strange rule about Schulze's? I never leave a battery plugged in anyway but still good to know!

If it was a castle HV yes but the Schultz was great in that respect. No The repair was not right or else it would have been a better run.

Hmmm maybe some chinese parts infiltrated their stock.

It will be interesting to see if 650 kv 67MM Prop and five inches of pitch on 10S2P Is too much according to schultz. I will be running the Monster 2000 this weekend. If the $189. ESC does it shultz is in trouble.

5" of Pitch? You are probably pulling over 150 amps. More like 300 at start up and we all know multi poll motors are harder on the electronics. I run a 3060 550kv motor with a 67mm prop in a mono. 60mph. I know it pulls 150 amps average.

I think you are gonna pop the other controller too!

But that is with a inrunner this is a outrunner amps drawn are much lower.

I disagree. Watts out is still amps in!

Generate 8000 watts still takes about 170 amps. Probably 300 at startup. (at 35 volts)
Inrunner, Out runner or a light bulb for all I care.

Outrunners typically use less Amps to produce the same power as inrunners. I fly big 50mm diameter outrunners on my airplanes swinging a 17x8 prop and only use a 55A esc on 6S! Never even gets warm. I wouldn't even think of an equivalent load on a 1515/1Y for example with anything less than a 180A ESC!

Outrunners are less efficient that in runners at THE SAME POWER LEVEL, gobs of data to prove that all over the web.

Well on friday I will go back to my tried and true method of testing. I will start with a small prop and go from there.

That is true providing that the two motors are made of the same quality components. You cannot take a Scorpian outrunner that has an eff. rating of approx. 87% and compare it to a Feigao/Pulso/Keda Chinese inrunner. It wouldnt be fair to the inrunner. At best they are something like 80% eff. and thats giving the motor some. Most of the data I have seen actualy puts them at 78%.

But if you take a high quality inrunner like a Neu, Lehner or Plett that uses the better compenents you end with as much as 92% eff. So it is true outrunners typicly are less eff. but only on an equal construction comparison. Take a look at the dyno data on the Neumotors home page. Look at the data on their 2215 inrunner and their 1900 series outrunners. Your going to find each one very, very close in eff. ratings.

There might also be an issue with the controller sensing the motor. I still think you get what you pay for within reason. None of my Schultzes ever puked an inrunner.

[RandyatBBY]

Time to have it fixed again, five years later it is. Any one have a way to get a hold of Schultz now?

Randy,

I will forward you an email to your gmail account about the specifics Matthias asks for these days.

Thanks Tyler

[david hall]

Tyler, would you mind sending that information my way also?

Thanks
