I have been testing POSKY 762's lately, and they seem to be having a problem.

When I taxi the POSKY 762's , I use a bit of throttle, the plane accelerates to 12 knots in seconds rather than staying at a constant speed like my Overland A300 does.

What do I have to do so that it can taxi normally?

What can be the issue?
