I am looking at ROAR legal ESC/Motor combos for my 2x4 Slash and my buggy. I have done a lot of research online followed up by looking on Youtube for video reviews, there is a TON of great information out there if you are willing to sift through it all. I think I have found my combo for both of my RCs, sadly not Traxxas, their BL stuff is great, but not ROAR legal.
One thing most reviews have in common is the reviewed product's unboxing, in most reviews this is about 1/4 to 1/3 of the video. At the end of the unboxing you learn that the product was packed in a box when the reviewer received it, I assume this already and really don't care to waste time watching the reviewer remove the product from the packaging, thank goodness for the slidebar! Now, if there is something interesting or note-worthy about how it was packed, then sure, throw that in there, if not, I can do without it.
So, if you decide to make a review video, we all love to hear other people's experiences with products we are interested in, please skip the unboxing.
