Wow... Figures, I just ordered, received and wired up one dna 30 last week into an Arlo. Thankful that I ordered enough parts to make 2 Arlos. I will be on the prowl Tuesday for the dna 40. Still like all my Mechs (tubes and boxes) but to be honest they have been sitting for weeks since I made 2 OKR T10s. If this works as stated in the PB interview and others here have said the T10s may be the next to be sitting around the shop.
