so i started to take leaves as i got the pleassure of real RC modeling..and i got ample of stuffs from MBMH...then my main head ache was motor blow out..so i started to alter my motors for me...the main dis advantage of a toy motor is its magnets..some motors from Mabuchi, and Johnson is far better ,sure, but mass produced chienese motors are good for nothing..so we cant allow the motor to heat up, as the property of the magnet is reduced..so my research shows, that, if a toy motor heated up,the torque is diminished..so i found a solution..wind motor for great torque, and use a gear box, with reduced voltage..as we know Voltage = IxR, its too easy..an automatic conversion is done by itself...so i got a high torque, with less amps,for a long time..without heating up...its all got from practical experience..as you are in Bangal, i hope we can meet one day..and capacitors..my experience shows that a mere 104 PF disc is far enough for circuits within 27 to 89 Mhz of radio..and if you are too concern,you can go for 4.7 Uf Non polar electrolytic..and even then can go for a relay switch, with a instant latching circuit, that can hold the motor instantly, and then released..i will post some article here soon..have a nice day..
