Anyone using them? I noticed they had some what looked to be like really good deals on hobby wing esc/motor combos.

I've ordered a lot from them, there great. They are over seas so shipping might take a while for something like a lipo. There advertised in the rctech banner, so there a well respected company

+1 for highly reputable but unless you pay for the faster shipping, it could take weeks and will definitely not take just days. Pricing is generally good but for HW stuff, make sure you check HW NA and compare with shipping factored in.

I order a lot of products from them. Fast and reliable seller also known on ebay as Dinball.

bought two HW combo sets from them with no prob.

I just received my first order from RcMart and was shocked how fast it got to my door (in Canada). I placed the order on Feb 6th, and received the package on Feb 17th. I was fully expecting a 4 week shipping timeframe like all of my photography gear I buy from HK off of Ebay. I used the cheapest option for shipping as well, so I imagine the more expensive option might be faster, but it doesn't seem worth it to me if the items get here that quickly.

I just got my first item from them as well, the Sanwa/Airtronics MT-4S. I was shocked as well by how fast it got to me, only 10 days.
