Stavros, go to the top of the class!!

It all works this morning.

Another step on the never ending staircase of learning. I assumed that because the battery charge light went steady, the battery was charged. Oh silly me >:(
I shall have to make sure its always charged overnight before using it.
Now though, I've found another problem :'( :'( One of the prop shafts is bent, and is causing a lot of resistance to the motor. So now it looks as though I'm going to have to replace them after all, which i have tried to avoid.
I hate refurbing old stuff. Its much simpler to buy new, isnt it?
Thanks again for all the advice.
Bob
