I owned a stinger as a second plane. It flew great, was light weight, and fun to fly. Some things I noticed about VMAR (my brother also owned one of the vmar sticks)--
Poor quality wood. Doesn't seem like real balsa. Some Viatmanese knock off
Poor hardware--they want you to use the ez-connectors for basically all controls--what a joke.
Poor covering--stick on kind. When we peeled it off to recover it after a crash, the color stayed on the wood. The new white covering wouldn't mask it, looked awful!
Instructions--didn't really need any, so can't give any feedback there
Service--pretty good, I guess. I also ordered the vmax .52 to go with it, and my brother ordered the .46 to go with his stick. His .46 was DOA, with a stuck throttle body. They replaced it, but it took a month. My .52 ultimately threw a rod after two flights in the air (and an extensive ground break-in, as per instructions). They replaced it as well, but also took over a month. I sold the replacement .52, before even breaking it in. The owner of that engine still enjoys it today.
I think they are hit and miss. Poor quality wood, poor quality hardware, Poor quality stick on covering, but they will fly. Mine died in an unexpected landing, but the wing lives on in a modified alpha fuse. nice wing!

Order one if you want it, but I guarantee you if you hold a VMAR model, then hold a hanger 9 or goldberg model, you'll notice a difference--like driving a Taurus, and then getting into a Lexus. yes, both cars will get you there, but there is a definite difference in quality. What does quality give you? better rebuildability, better survival in "hard" landings, and so on.
