Title: direct drive small brushless trike
Post by: pankaj on January 23, 2011, 04:58:41 AM
since the Kv of motor of is pretty high it slips very much in starting  :( but its speed is pretty high :thumbsup:.

Then buy one of those cheap rickshaw toys that you get on the street and put the top shell on this thing.. You'll have the most unique RC vehicle in India.. my guarantee! :)

It obviously has to slip, else the motor would burn. BTW nice toy to play at home. Ever tried running it on a carpet? It will be fast for sure  ;)

it's an on-road vehicle ...  :giggle: :giggle:
btw this thing needs very precise control  :'( as the motor is directly mounted on servo.so i have never tried running it fast but it runs good on road at medium speeds.

You can do DR physically, by putting the linkage rod on the innermost hole on the servo arm, and outermost hole on the control horn side (or however it applies to your setup).  Basically, you want to get the minimum movement on both sides of the linkage rod, for full deflection of the servo arm.

thanks Anwar sir  :bow:  :bow:
but in my case there is no linkage rod ,as it is directly mounted on the servo horn using L strip .

thanks
