Hai.good evening,yes sure..but by this time i manage to overcome this problem respected friend.instead of using transistors, now i am using mosfets in parallel, the BUZ series is the best option for me, and its driven by a PWM circuit, based on IC NE 555. so i can get more than 5.6 volts, on a 6 volt battery.its variable control is varied by the servo, that is why i always use a sliding control,instead of a rotating one.and almost at the lower end of the variable control,motor stops . for this i use 1 Kilo ohm, instead of 5 K ohm,and in that lower extreme end i placed a DPDT switch,as the servo arm touches at this switch, yes indeed for reverse.to control the speed at reverse i uses a 12 ohm, 5 att resistor. so working nicely..here in my country the hole RC stuffs are costlier, in vain, and i am not willing to pay many thousand dollars for a simple stuff, as i can make efficient RC systems by RX TX 2, or 6 B ICs,needed crystals, from 18 mHz to 49 Mhz,all driven by power transistors,or can make even simply by using a FM mike with an FM radio board..how much channels..? thats all about to me...now i am concentrating hole of my ability in electronics to make my crafts worthier.thanks for the valuable advises.
