We shall call this the first to keep the records strait. This is the bird I will try to build.

Hey John, definitely a good idea to make the electronics accessable. They're not on my Dr.1, but that was due to intense lightness being required! All my other aircraft have removable servos / receivers / ESC's, etc. My servo's generally go in the fuse, above (or underneath) the wing (which is generally removable). I usually have balsa cross members in the fuse that they rest between, and use the supplied tiny self tapping screws to screw the servos into the balsa members. I really like the HS-55 sub micro servos, but there are great even smaller ones available from companies like bluebird now (check out www.bphobbies.com for all these supplies...). My favourite way of doing removable wings is with a combination of small dowels and tiny rare-earth magnets, or nylon screws. Receivers / ESC's are generally held using velcro or double sided tape. One thing to worry about is heat with the ESC's - they can get pretty hot, and do nasty things like cut the motor if they get too hot. It's a good idea to have a good air flow over them, so in the cowl can be a good place for them. What motor / ESC (speed controller) / battery are you planning on? How will you actuate your control surfaces? I like the pull/pull threaded method of doing them, it's super light.
