Gampla Posted November 26, 2018 Share Posted November 26, 2018 So what about brushless on nihm batteries?Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Nickarla Posted December 12, 2018 Share Posted December 12, 2018 Is there a reason why no figures are given for 1000kv, 1100kv or 1200kv? With 6s the number start in the red. Will 6s be more efficient running on the lower kv? Quote Link to comment Share on other sites More sharing options...
projektzwo Posted June 26, 2019 Share Posted June 26, 2019 I’m still trying to find out how to use this chart, but I’m total noob... I’m running two 2S 7.4V 5200mah batteries (which means 4S?) and I have single 6S battery which I was using with jumper. I’m running the oem hpi scream brushless motor and the oem ESC and doesn’t matter which batteries I’m using in less than 1min I could easily make the motor and esc proper burning. Now I ordered new ESC (tekin rx8) and I’m not sure if its possible to run it with the hpi scream motor. And if I want (need) to change the current motor, what should I get I mean like specs (how many KV). Also what else is important to know to make the right choice for the motor?

mond Posted June 27, 2019 Share Posted June 27, 2019 You can run that motor with the Tekin. The right choice of motor for a Tekin ESC is a Tekin motor :). The RX8 is paired with a T8. Depends what you're running it in though but I'd get a sensored motor to run with that ESC. Quote Link to comment Share on other sites More sharing options...
projektzwo Posted June 27, 2019 Share Posted June 27, 2019 Thank you, but Im wondering how many KV to be that motor. Also is there that much difference between tekin t8 gen2 and gen3 ? Quote Link to comment Share on other sites More sharing options...
EvilR Posted August 25, 2019 Share Posted August 25, 2019 Only just looked at this! Is the given sweet spot based on a typical rpm max rating of 60k Or is the 30k a general rule for our RC brushless motors? Ask as I’m about to run a 1900kv motor rated as rpm 80k Quote Link to comment Share on other sites More sharing options...
Robin Uren Posted January 25, 2020 Share Posted January 25, 2020 So my 6s outcast comes stock with a 2050kv motor as far as I can work out this chart suggests this is way to high. Why would they put it in the truck if its the wro g spec? Quote Link to comment Share on other sites More sharing options...
Robert Madigan Posted May 2, 2020 Share Posted May 2, 2020 Hi, new guy here 👋 I’m new to the world of RC cars and bought a Tamiya Dark Impact DF03 as an introductory car. After running on the standard kit for a week I decided to upgrade to a brushless set up. It seemed to go alright but after 10 minutes I started incurring a repetitive problem. It will run for 10 minutes but then cut out. I can hear the transmitter and receiver working together but there’s either no motor movement or is stutters. If I leave it for a few mins it then seems to go again before cutting out again. I’m running a LiPo 4000mah 50C 7.4 2S, a 4370kv 9T 820W brushless motor and a 60A 5.8v/3A ESC. Any ideas? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
