Pros: Everything shown in the pictures came in the box and it arrived on schedule. I like the quality of the engine... it's made of a good quality metal and the scale of the device is perfect. I'm looking forward to getting it to operate as indicated.
Cons: I haven't been able to get my engine to run, yet. I'm hoping to figure out the problems soon. The instructions that accompany the kit are almost useless. They are missing important steps in assembly and operation of the engine. There are no online videos that show you how to set up your Sterlingkit engine step by step. Also, the instructions should include "Troubleshooting Tips." I suggest that Sterlingkit get an American Ex-Pat who is familiar with the engine and who can speak good English to re-write the instructions and then do NOT copy the instructions on a office copy machine because the pictures are too dark to be useful. The latest problem I have is that the little muffler will not stay in the hole designed for it. Finally, the engine doesn't come is a simple battery holder and connector; you are not told online that is needed to provide the spark, but the engine won't work without it. You either have to make one yourself or buy one at a hobby store or online. I will update this if I can get the engine to run.
My husband was thrilled to receive this as a Christmas gift. He has been "tinkering" with it since opening the box. I was really happy with the purchase.
good looking engine and fast shipping.
Machining, detail and craftsmanship is excellent. Happily impressed.
Like it very much
