This was an estate sale find and I know nothing about it. I found a similar one here on eBay and believe this is a "3D helicopter kit HK450 CCPM (Align T-Rex Compatible) Ver. 2". I am not finding any markings or labeling or instructions in this kit other than HK450 to give me any info. This looks like it is complete and most of the parts packs are sealed. Looks more complete than other one I found which didn't have any decals. Sold as is so examine the photos. Should make a really cool helicopter!
