I am not sure what this is. Do you mean the radio with telemetry monitoring on the laptop.
A quarter or 1/8 turn locking mechanism that locks the whole center mechanism is at the top of my list but some of my original attempts have proven unreliable. That will be real quick. Still requires some work to get a reliable repeatable device designed.
I prefer the battery locked in like you have it but maybe some better thumb screws or the electric screwdriver would be ok.
You do have to unscrew the lid to access
the compartment where the batteries are stored.
But it seems pretty easy to me. I keep a palm size rechargable drill in the case. I do the battery change now like a pit crew, so it only takes a minute. The way I designed the lower hull allows for a power distribution board to be screwed to the bottom . I then formed the two shelves forward and aft to support one or two batteries side by side. I could form the bottom so that it would allow the batteries to be velcro'ed or strapped to the bottom of the hull
.
Is it easy to replace the batteries, or do you need to dismount the apm to gain access?
Very nice design.
Hey Everyone,
Sorry I am just now speaking up. I am glad to see you like the design.You can see in the image the lid fits with the GPS in place. I often fly with it off if it is not raining. It would probably be a good idea to protect the GPS. I imagine with the uBlox I have coming in the mail I will be fkying with the lid on rain or shine.
I had also planned on using an arming plug like the one you see here until I came across the switch while picking up some fuses.It was specified for 25 Amps @ 125V, which seemed reasonable to me. But I think I see it as a weak link. I think I will probably go back to the arming plug.
HUGO Specs:
I will try and get an expected shipping date soon.

They don't really need to handle as many as you might think. The rating is usually given assuming the load is on but in this case nothing is drawing the amps until the motors are running. Then the switch can handle more amps since it's contacts are closed.
Mark, is the Aerotestra for sell? Didn't see anything about that on the blog.
As boards mature its going to be all about looks and simplicity.
Looking great! One question, Is there any anti-spark feature on the power switch? The reason I ask is that you can get a lot of spark when connecting batteries, and sparks builds soot and ruins the switch over time. With normal battery connectors this isn't normally a problem, since the spark only affect the tip of the connector where it first connects.
Beautiful frame.
You and Aquacopter are definitely heading in the right direction and I like the panel access on yours better.
I take it Kydex construction like theirs as well.
I know your working on your website, but a little info like size, weight, motor size and max loaded weight might be good.
Vacuum forming has great potential for these things.
