Default RE: Picorare Build Thread

As well as almost finishing the wing (front fuse section missing), Ialso completed the fin/rudder assembly with the fin tip and subfin installed, shaped and the rudder fully hinged now. As can be seen on some shots, Imanaged to be careless on just one pass of 80 grit and needed to use a little filler on the fin sides to even things out. Working on such small surfaces with very little wood tolerance makes things tricky not to mention that the airframe is practically weightless (it has to be held down with lead shot so it can be worked on).

I mounted the wing in the back with two 6-32 nylon screws and recessed nylon washers but will replace these for 8-32 screws as the former feel a little flexy - wouldn't want the heads popping off (in flight or when umounting the wing - that would be a PITA - requiring them to be drilled out)! The front two dowels will be installed next, now that Ihave popped off the canopy and have access to the front of F2 (whew! - tricky to align right without access.) Then, I'll work on the wing fillets.

I can also proceed to mount the canopy which I'll actually do with a single 4-40 x 1/2" screw and blind nut in the rear (instead of magnets which I don't have) through small 1/16" plates. The front will have two dowels into the nose ring.

Once that's done, there won't be too much more Ican do until I receive the motor as I want to delay mounting the stab until Iproduce the tuck lines (for ease of sanding). The latter require the final fuse width and side to canopy continuity to be finalized. I'll probably go ahead and install the control horns in the rear awaiting linkages. My list of things to do prior to covering is actually 15 items long... I'm sure I'll manage to add a few more things (there's always something).

Below are some assembled progress shots (plan in background on wall is of 60 size Tipo). Getting close!
