I have the Mars rover. I have the Mars rover. With the Spring motor. I've sanded and lubricated all moving parts with paravan. And there is still too much drag for the motor to run on its own. I think the problem may be between the flat drive here and the 2 gears that are set at 90° off of that, But it could be just an accumulation of all of the moving parts. Is there something I can do to make parts move more freely possibly a different Lubricant?

I have been modeling for over 20 years I have been modeling for over 20 years, mostly involved with model train layouts. There are no words in the dictionary that would accurately describe your puzzles. I am so impressed with your product. I find myself unable to pull away from my workstation. I am currently building the train and passenger car puzzle. Your materials and instructions are wonderful. I have large numbers of people involved with my train layout and they will “all” be exposed to your product. Very impressive.

Great concept but it comes with way too… Great concept but it comes with way too many fragile tooth picks and they need to be cut down to size. The small holes make it impossible not to break the toothpicks. My 14 year old son who has successfully built other models found this extremely frustrating and did not complete it.

Looks good Christmas present so not sure how it will eventually work out, but looks great. Very fast delivery. I'm looking forward to my dad starting assembly.

I received the 3D Spider kit as a…Birthday gift I received the 3D Spider kit as a birthday gift. I was excited to get going on it right away. I have built other kit's in the past. Opening I was surprised to notice that there was not word in English indicating inventory nor was there any instructions.. The You Tube video was just as bad. How many rubber bands are there suppose to be used, and how many are extra. I still do not know how many bands go on the hooks that drive the legs. It is a great product just missing a lot of information.
