Boy thats cheap alright, makes me think of the saying, "you get what you pay for". I've had some experience with Raidentech and they're pretty good to deal with, as long as they have what you ordered in stock. Although, in their description they state weight as 500 grams, that's only 17 oz, that's imposssible. I'm frugal and even I would look at it but wonder if the $40 would be spent more wisely elsewhere. I just put together a Tower 40 ($70) and think it's pretty good, but others would disagree with me. I do have 40+ years of modeling experience so I do have an advantage. If you're a rank "newbie" and just testing the waters to see if you like flying RC Aircraft, you might get discouraged with a really cheap ARF. You might want to look at some of the RTF electric foamie trainers. I'm not saying it's bad, I haven't seen it, but remember cheap can be very agravating (hazardous & crashes due to poor materials and design). One question I have is the covering a MonKote type, for easy repairs.

One thing I"ve learned in my 40+ years of modeling, you can be frugal, but just the cheapest solution can be the poorest solution.

Your 40fp and radio, if in good condition, are a good motor/radio combination to have for a start.

You're wise to ask and do your research. Good flying to you. It's really fun.
