The top at the cabin frame and the bottom at the extrusions are set, leaving the two side ones to worry about. I wish to keep working at the fuse, not having an engine mount at this time.

If you have the mount then you can use it to sanity check the position of the lower frame rails and the nose gear shelf. In my case I had to do some slight repositioning and trimming to get everything to fit just right. If you have access to another builder's engine mount then try to borrow it, otherwise I would order it/fabricate it first. Good luck!

I am talking about the location of the firewall in respect to the 2 side skins. Once all the holes are drilled in the side skin at the firewall rivet line it will be positioned, possibly incorrectly.

Can someone confirm my visualization that the servo arm retracting should result in nose up trim?

I did have to do a fair amount of trimming on the bottom lugs of the engine mount (the new-style ring mount) to get them to fit between the rails, and had to make shims to fit underneath the rails to take up the slack. I suspect thats pretty normal. The other points on the mount fit fine without adjustment. All else being equal, if you know what engine you're going to use I'd go ahead and get the mount now. It will come in handy again when you mate the forward fuselage to the back half. If that's a problem, forge ahead without it.

With retraction the Tab is moved down which raises the elevator which pushes the tail down and the nose comes up, yep you are right. Bob Spudis In a message dated 8/3/2009 11:46:19 P.M.
