|IT RUNS !!
I asked the supplier how to wire things. He also told me to put a capacitor 47nF in it against receiverproblems. Today the sendchristal arrived. I had some startup problems but now it runs, speed is indeed adjustable, it can crawl but with noise, and it goes forward and backwards. It is able to push a few cars up a hill. Still I'm not quit satisfied. I will have to sophisticate things, but not sure what, to make it more smooth running. As soon as my daughter and sun explained me how YouTube works I show you a small movie.
Have to go now, more to come..
