blockhandler asked:
I have two engines of 12 C.C. v run off of a car battery, continuously charged by a car alternator 50 amps operated by the engine of the mowers v. 6.5 v. A motor driving each rear wheel. I am checking with a "Futaba" transmitter and receiver 12-15 volt regulator with electronic engine speed of 50 amps to the two engines. When we hooked up for a first trial, resulted in three problems. I 'll the lists in order of importance to me but anyone who answers any of them will be Greatly appreciately for me! 1. There is no reverse function 2. When I throw the joystick on the transmitter and released back to center, the engine should stop right? He does' t. He doesn 't stop until you push the lever until the end towards the opposite direction from which the engine wants to give back. A bit like if you had even reverse, I wouldn 't have enough movement of the joystick to reach it. 3. The regulator of the speed of the engine has a "BEC" circuit of the battery eliminator 3 v. Still need to hook up my package of 4-cell battery to use?. HELP!

It would be much less hassle, and probably cheaper, too, if you paid a neighbor kid to mow the lawn while you layed in a hammock and “remote controlled” the kid by yelling commands at him like “Stop”, “Back Up”, “Turn”, “You Missed A Spot, Do It Again”. Then you wouldn’t need batteries. Just a twelve pack and a megaphone.
This sounds cool! I am in fact making My own RC lawnmower! I have the frame made it is a all electric (blade too!) here is my website for it: I was going to do my wheels with out a speed controller, but after doing the math I figured out that it would go 10 MPH way to fast for mowing lawn(IF YOU WANT IT TO LOOK NICE!)that is why my wiring diagramn dosnt have a speed controller in it. What you need to do is connect the electronic speed controller to the battery and then to the throttle channel on the radio (if it is not electronic and it is manuel throttel type like from a scooter, just connect it with a servo to spin the throttle) from the controller you would split off to two center-off momentary switches controlled by servos (take a reversable cordlles screwdriver apart to see how to wire) you shouldnt have a problem with the conttroller wearing out from the starting current because if your conttroller is 50 amps your motors should only pull 2 to 5 amps and probably no more than 15 amps when starting. from the switches it would go to the motors. now with the conttroller you should have what is called a trim pot or trim nob it should say what channel each pot controlles, moving this should allow for the controller to stop in the middle position. EXPERIMENT with it! as for the controller “BEC” 3 v battery eliminator circuit, I think this may be a switch to turn the controller on and off, thats what mine do. Please tell me if this is helpfull!
