### ⭐⭐⭐⭐ Aligning the Electric motor drive gear
*by K***A on December 19, 2020*

As mentioned by most all reviewers, this engine model was a bit difficult to complete. The actual motor parts are fairly straightforward and assemble easily. However, the actual plastic this is crafted from is unusually brittle, and will crack if you draw down too tightly on the screws. Was able to get it together in slightly over 2 hours, but getting it to actually RUN by way of the small electric motor was considerably more difficult. Major issue with POOR alignment of the electric motor pinion gear and the "flywheel" get on the motor model. When mounting the small electric drive motor to the back of the model you could easily see the pinion gear barely touched the flywheel drive gear. Applying power to the drive motor resulted in much gear grinding as the crankshaft end piece flexed enough to completely disengage the gears. Used a Dremel to sand down the electric motor screw mounting pins and was able to get a more substantial alignment of the gears. However, with battery power applied the crankshaft end would flex "UP" and away from the pinion gear causing it to slip. Fortunately, using a small plastic bushing from a TV wall mount kit was able to fashion a bushing which slips over the flywheel spacer bushing and is large enought to ride along the outer rim of the flywheel ring gear providing just enough DOWN force to hold the flywheel gear in alignment with the electric motor ring gear. Motor now runs nice and smooth. Kit maker needs a serious redesign of their drive motor gearing, and consider adding a small plastic bushing to hold down the crankshaft end so it maintains alignment with pinion gear when power is applied to the model.
