I just spent some time in the tail of my -3 recently and this is what I did also. Lots of smaller peices of styrofoam "board" with some thin wood on top (the real thin backing board type stuff) with a bunch of blankets/padding on top of that.

BTW: The time I spent in the tail was to modify it to carry my ski's (documented at Ski Truck Epilogue) - can't wait for the ski season to start!!!

If you follow VANs directions while you build there should be no need to crawl into the tail cone. I didn't need to for my build and everything worked out.

This may be true during the build process (I'm not a -12 builder). If talking about after the build, there is a need for inspection and maintenance back there. Probably could be done with inspection panels though. Inspection panels would kind of take the adventure out of the event though!!

I have followed the plans to the letter...never strayed out of order at all. But I'm thinking there is a need to get back into there, after the main plane is built, to install some of the Skyview avionics components? As some have pointed out, you don't have to go in there very far, but I will need to enter the tailcone a few feet for component installation. This is per the plans, to install the ADAHRS box, I think (**edit: yep, just as Dave points out in his post and photos)...I'm not that far yet, but there is an ADAHRS bracket at the very top of the tailcone- a few feet in, that gets something hooked up. I'm hoping that I can kind of reach that from the cockpit, as did Dave and others.

Thanks for the replies and ideas, everyone!

What we did: It turned out not to be too big of a problem crawling back there. We layed down strips of foam on the closest tailcone bulkhead and then place a board on top of that. Since we had already run our control cables we were careful to place them between the strips of foam and not squish them into the bulkhead. There is also a plastic control cable guide that is attached to the bulkhead, and it sticks up above it about a half inch. We were careful not to lay the board on this, and were also careful not to shift the board when we were laying on it.

What we should have done: If you can, leave the tailcone off as long as possible. It will be alot easier to access the tailcone and the fuselage section if they are seperate.

Support your tailcone before you climb in it on a sawhorse or other retaining device!!

Talking Foam Blocks

I made Styrofoam to put in the tailcone. I used 1" foam,stacked to 3 inches.
I used white glue and let the panels dry under weigh of books or wood for a couple or more days.

It is easier if you find 3" foam but this is what I had.

Cut to shape once the foam is ready on a band saw, put the foam in and do what you need to. DO NOT fly with this foam in the aircraft.

I failed to mention that I followed the advice of a rather sharp fellow builder who suggested that it would be easier to mount the ADAHRS box to the mounts and then rivet the whole assembly in at once. He was absolutely correct!

I took a different approach, I added 4" inspection ports one the side near the tail (for counter weight access) and along the bottom centerline for wear plate access and autopilot servo inspection.

Sounds like GREAT advice, but I have already riveted the mount to the top of the fuse. I'm not where I can view the plans, but if IIRC, that's just held on with a 4-6 rivets. Sounds like I'll remove the bracket if able, mount up the ADAHRS equipment, then re-rivet!

I should have left the tailcone off, but again, I just followed the plans. If I build another one I'll leave the tailcone off for sure until some of these steps are done!

Thanks everyone.
