Good morning..i have sketched my tug, on expanded polystyrene, by last night. its span in to 4 feet, and 11 inches wide. but i hope i must reduce one feet to get a chubby appearance. here i do not have any powerful motor...so after searching few hours among the toy motors, i couldn't find any one. so i purchased two identical old VHS HQ VCR from a scrapyard. i took off the motor from it, a brushless , based on PWM technology. its based on 9 volts DC, and can deliver up to 3/4 Hp as my early notes teaches me. so to drive it i have to wire a PWM circuit this night based on CD 4020, along with IC NE555. so i can simply control the motor from, stop, clockwise, anticlockwise, and brake, as we found in VCR.its a hard job to do..only then i can go on...then willing to add a simple high pitch prop from a brass sheet..i will post you all pictures to you as my work progress...so now a request...may i save some photographs from you..? for only a reff:..? please...
