DT750 Brushless Outrunner 750kv http://www.hobbyking.com/hobbyking/store/__6247__hexTronik_DT750_Brushless_Outrunner_750kv.html work with HobbyKing Red Brick 20A ESC http://www.hobbyking.com/hobbyking/store/__25112__HobbyKing_Red_Brick_20A_ESC.html Title: Re: will hexTronik DT750 Brushless Outrunner 750kv work with HobbyKing Red Brick 20A Post by: satyagupta on February 24, 2013, 03:03:13 PM yep it should work, i am using same motor with 20A esc does not get too hot, but yes bit warm not very. But its very good combo

In Electrical Engineering the Basic Rule is LOAD IS THE KING. You can easily overload by using oversize prop in diameter and/or pitch. Title: Re: Brushless motor compatibility Post by: profoundr on March 02, 2013, 10:53:34 PM means i can use it :headscratch:
Title: Re: Brushless motor compatibility Post by: santhosh-r on March 03, 2013, 08:45:13 AM You can use a higher amp ESC with a manufacturer recommended prop and motor combination..
Using a higher amp ESC will never harm a ESC but the advantage is the heat produced will be less. Title: Re: Brushless motor compatibility Post by: KALYANPRODHAN on March 03, 2013, 10:00:37 AM You can use it with limitation imposed by Prop. Do not use prop except 11x3.8 or 10x4.7 to be in safe power range. More safe prop is 9x5 prop (Static thrust near about half).
You can cross check the power requirement and hence the current from below. http://personal.osi.hu/fuzesisz/strc_eng/index.htm Title: Re: Brushless motor compatibility Post by: rcpilotacro on March 03, 2013, 11:13:08 AM Kalyan, incomplete info, what about battery ? did you check with him how many cell batt he is using, 2S, 3S , 4S ? Depending on the batt used for a particular KV motor the prop will be different, higher the number of cells, more is the voltage and therefore more is the RPM and like Kalyan says More load. Most motor data gives you what prop to use with what cell.
@Kalyan More Safe is also called Safer , a comparative statement ;D Title: Re: Brushless motor compatibility Post by: KALYANPRODHAN on March 03, 2013, 08:39:48 PM My English is getting worst day by day and violating rule by moderator is indeed a crime (Bad English).
So I stop posting now till new plane build thread. Don't blame anyone. :D :banghead: Title: Re: Brushless motor compatibility Post by: profoundr on March 04, 2013, 11:43:06 AM i m using a 3s battery :)
Title: Re: Brushless motor compatibility Post by: rcpilotacro on March 04, 2013, 02:33:07 PM 11x4.5 is ideal and let me tell you about DT750, it is one of the good motors, the shaft length is high though and needs to be trimmed (If you want to that is), 11x3.8 is good too, both will give you ample power for a tri
