There seems little point in criticising Lima 'pancake' motors time and time again. This will achieve nothing. Lima no longer exist, so where exactly are the criticisms directed, and 'what' do you want 'who' to do about it?
Repeated criticism is not going to magically remotor your locomotives with the superior offerings from Bachmann and Heljan from recent years.
You have your lemon and have 3 choices:

1. Suck the lemon.

2. Stand with your lemon looking lost.

3. Make the most of what you`ve got and get on with it.

I am going for option 3. I have a large number of Lima motors in my fleet, and for the time being they are here to stay. A point worth remembering is that no one motor seems the same, Some have better running charactersitics than others. Some need more TLC, but some run as sweet as a nut, even at slow speeds. Likewise, most Lima pancakes are very noisy, but 'some' have an acceptable level of noise reduction. Look after what you`ve got, and always keep your motors oiled and cleaned. Here`s a tip that some may find useful:

I was thinking back to school days, and how we marvelled at the idea of a potato being able to light a light bulb or power a clock.......
With no potatoes to hand, I settled for a trusty lemon. I decided to change the chemical energy in the lemon into electrical energy. Inserting a copper and a steel wire makes a circuit and allows a small electric current to flow. One lemon produces about 0.7 volts of electricity. At that voltage the effect is totally harmless, but connecting your Lima motor gives enough power to give it an extra bit of bite, and this charge should hold for at least a month......
As we all now, pancakes are always so much better with a splash of lemon!
