This is an example of what people are trying to explain to you. If someone isn't asking you specifically for advice, don't give it. It is very easy to come across as condescending if you do.
Edited by emsgoofAs for your MC80, a trick is to go speed 2 and got 1 click towards the board center and click at 2 to go 1 towards the more edge. Oh and deploy the MC80 about distance 1 or so from the board edge, you should have no more problems.
