4M Project Kits 3640 Review by J. Hoffmeister
I echo a previous reviewer's experience. With the rubber gaskets we were provided, I do not believe that the laws of physics will allow assembly. I am fairly adept at assembling this sort of thing, but have given up on this product. When the directions warn you that assembly will be difficult, take this warning seriously. I also note that the "pulleys" provided with my unit are different from the illustration in the instructions. This makes me wonder if the company has changed the sourcing for this product and, consequently, there were quality control issues.
The very first thing that the instructions state is that the product is not a toy - this is exactly correct. Do not purchase this item thinking that there will be fun involved.

My son recieved this present as a gift. He has thoroughly enjoyed it and would recommend it to others. We have only had it a short time, but so far so good.
4M Project Kits 3640 Review by K. Brubaker
My son is a paper airplane nut, so he had to have this kit. Unfortunately, after the better part of the afternoon we've been unable to get the launcher built. The motors need to be inserted into two circular holes on the plastic base, and are very difficult to push through. Lots of force is required (much more than my 10 year old is capable of exerting), and the delicate wire connections on the motors are getting all bent up. The instructions suggest lubricating the motors with dish soap to facilitate the process, but in our case it didn't help. I've tried enlarging the holes with sandpaper, but again, without luck. At the moment my fingers are bruised and sore and my son is disappointed. I suppose if I keep sanding away at the plastic base it may come together eventually, but I must say this item seems more like it was devised to frustrate than educate.
I returned to have another go at this kit a few days after writing the previous review. I finally got the first motor inserted into the base, but the gasket around the second just couldn't bear up to the stress and broke as I tried to slide the motor through. Perhaps I can affix the motors with silicon gel. That should work, if I build a rigging to hold the motors in position while it dries. More likely, I'll just throw the junky thing away.
