Having read all of the comments to date concerning the 3.0 version, what I've come away with is that approx 30% of the respondents are experiencing coupler and engine wobble issues.
Versions 1.0 and 2.0 did have coupler issues but they didn't have any wobble related issues.
Thus something changed at the factory while producing Version 3.0 - either there may be a bad assembler or quality control of the gauging of the wheels has slipped.
Additionally what I found concerning - one individual who was experiencing wobble also didn't have enough power to pull an average consist. It maybe that there was to much friction at the contact point of the wheels to the track which then reduced the remaining available power to pull cars.
The engine now starts smoothly but may coast a bit to much, especially in reverse, when trying to conduct coupling maneuvers causing minor crashing.
Also the horn sounds need to be addressed as they are anemic along with upgrading the Nylon gears to being metal.
Overall many of the respondents found the engines' ability to pull excellent and were quite pleased about its ability to pull consists on a grade without any issues.
Nearly all of the respondents seem to agree that some form of conventional control would make this product a homerun.
Overall Menards has done an excellent job considering this is their first attempt at releasing an engine with remote control capabilities.
I and I imagine many of you have found these Beta releases very intriguing.
The excitement that it has created on this site is amazing and fact that 200 units sell out within a couple hours also goes to show how broad ranged and powerful this site truly is.
Let's hope that the shortcomings will be fully addressed and the improvements implemented prior to a full blown production release.
