I normally run the S9551 in my other on road cars, but I bought a 'budget' S3050 for my mini, to see if I get into it before I spend heaps of money on it....

When the S9551 is hooked up, but NOT powered up, I can move the wheels (and subsequently the servo) left to right without any resistance at all. I cannot move the S3050 at all.

I powered it up and it seems to work ok. Is this normal? Am I going to come into trouble soon?

Cheers
