+1Your 2150 KV.
I guess it could be sumd up like, heavy=lower kv, light=higher kv?Kind of a loaded question. It’s like “I have 2 V8 engines a duramax and a built 350. which one will make the trip up the mountain better?” . I think it will depend on other variables which is best for your uses.
Honestly, it goes over my head..theres different winds, with different targeted rpm ranges ect..Basically lower Kv means less rpm with the same voltage. 3.7v x 2150kv= 7955rpm 3.7v x 2600kv= 9620rpm. So that’s 2021 rpm less per cell “with standard LiPo”. So my question is how do we get more torque with less kv? In theory couldn’t we use higher kv and just gear accordingly? Or is that too much strain in the system. I do believe the rpm limits of the motors play a huge role in the decision making as well.
Duramax will always win... lol.Kind of a loaded question. It’s like “I have 2 V8 engines a duramax and a built 350. which one will make the trip up the mountain better?” . I think it will depend on other variables which is best for your uses.
Also what about different grades of motors, example: if you had high end 2150kv and a cheap motor 2150kv wouldn't the high end have more rpm ?? therefore giving more power, not sure would that be torque or speed ??Basically lower Kv means less rpm with the same voltage. 3.7v x 2150kv= 7955rpm 3.7v x 2600kv= 9620rpm.

My understanding is the high end motor will be more likely to run at the advertised rpm, the lower end less so,ie, I've heard the blx/spectrums typically run slower than advertised by as much as 200rpm. Don't quote me, I don't own an analyzer,but I know I've read it somewhere.Also what about different grades of motors, example: if you had high end 2150kv and a cheap motor 2150kv wouldn't the high end have more rpm ?? therefore giving more power, not sure would that be torque or speed ??
A stock TpPower motor will normally have a rpm limit of around 60000 rpm whereas a cheap motor may only be 45-50000 rpm..!!
What happens then
Agreed!Duramax will always win... lol.
Not biting..Duramax will always win... lol.
Thats funny, I was really thinking about diesel vs gas, but I am a Chevy guy. Having said that, I wouldn't turn down a Cummins or Powerstroke either!Not biting..
JK, a brand is a brand..if it works, I like it
Also, the lower quality motors use lower quality bearings, lower quality copper for the windings (which increases I2R losses) which all contribute to higher temperature motors and lower RPM's. At least that is what I have read.My understanding is the high end motor will be more likely to run at the advertised rpm, the lower end less so,ie, I've heard the blx/spectrums typically run slower than advertised by as much as 200rpm.

Then QC comes into play, quality of materials, assembly and so on.
The actual rpm rating isn't a big deal, you never really want to hit max rpm anyway as the top efficiency of the motor is generally at lower than max rpm.
7.3 is the brushed motor of diesels. Just sayinHooray 7.3PSD!!!
In the long haul, Cummins wins. 6 banger baby!Agreed!
