I bought this kit because, well because it only cost a couple bucks. Didn't realize it wasn't an 18mm kit until I sat down to build it. So didn't have appropriate motors at the first launch opportunity. I had to trade an 18mm motor for an A10-3 to launch it. I'm not sure why this thing has a payload container, as its carrying capacity in both weight and volume is nearly zero. Construction is a snap, took about 10 minutes. | ||||||||||||||||||||||||||||||||||||||||
