Steve has made some mods to his Pro2 Landing Pad to make it lighter and able to work with the hc-90's. It's basically the same idea, but now you can put any plate you want on the bottom using the three 3/8th or two 1/4-20 tapped holes. With the 7" Pro plate attached it is several ounces lighter than the 1st version (bringing just under a pound). With no plate attached it's about .5 lb.
I just picked up his protoype and it's nice. The production one will put the plate about 1/8th inch lower for more clearance for the hc-90 (I have to smear Lisagav on the batt to squeeze it in to the front spot). I don't set my rig down regularly unless it's on my cart's foam pad, but it's nice to have the ability to do so without putting all that weight on the batteries. Using the new "foot" I'm also playing with the ability to move the front battery lower/adding a fourth battery (for beastly cameras) or moving the front battery way forward for lcd's (like Hugo's rig). I'm not a fan of adding dead weight so this will give me some options to fight the dreaded knee-banging post.
I'll fly around with it for a week or so and make sure all is well and report back. Here are a few snapshots:
