So I'm embarking on this adventure for carrying mine. I ride a Yamaha FJR.
Originally I bought the backpack with the intent of carrying it while riding. But then I got to thinking that I have the top box for a reason. I checked it out, and the Phantom can fit in it. So I got to work. A trip to Hobby Lobby and a package of soft foam. This is what I cam up with.
I built it with 1 inch layers. The top box is tapered towards the bottom so the layers allowed me to work my way up, using the most space possible. But I worried about it bouncing out. So I bought a Yamaha brand bag for the top box that zips up. I cut another foam piece that sits on top and then I zip the bag up.
I haven't cut out the sections for the batteries or the remote yet because I'm attempting Version 2.0 now. It was apparent early on that the white foam would get dirty real quick and look bad. I couldn't find foam in any other color that soft. The charcoal foam I found online was much more expensive.
I took a sample piece of foam and dyed it black. Turned out OK, so I started over. My first attempt, I tried to cut the hole for my P3 each layer as I worked up. It didn't work out as well as I'd hoped. This time around, I plan on building the block first and then cutting out the necessary areas. I dyed 12 layers worth last night. I only need about 8, but I wanted some spares.
I'll do a full write-up when I'm finished. That is if it turns out halfway decent.
