Yeah, kindda has the Innodyn flavor don't it? Some things they've got going for them is they have pictures of all their inventory waiting. You never saw that from Innodyn. Another thing is that Ack is an already established company with other products. I have also corresponded with them and got a prompt response to my query. If I had to take a stab at it, I would guess that some other competing companies may be influencing things since Acks 406 ELT with GPS encoding is significantly cheaper than anybody else's. Ack may be keen to this possibility so that's why they're going to be present for the last test and there with their equipment too. I dunno, but I wish they'd get it approved soon, It's one of the last items I need to purchase in order to be complete on the fuselage. Now, where is that BD-10 equivelent? I want one.
