Right tip done

Completed the right tip.  I've decided not to install lights, as far as I know they're not required for RAAus rego and I don't plan to fly at dusk.  In any case, I can always make an access point in the tip later if required.

Really don't know why they didn't make the entire tip out of plastic, it would have been much easier to install than a separate nose tip!…

Spar Web Doubler

Cut out the spar web doubler today. Used a dremel saw and smaller dremel tool to do the cuts on the .063 thickness aluminum. Went through a number of cutting wheels!! Also measured and cut out the upper and lower spar caps. Now I need to find a bending brake to take care of the 90 degree bends for the spar tips and doubler. Maybe I can build one.

bottle nose root ribs?

Root nose rib 75-w-4-1 drawn out does not match to root rear rib 75-w-4-2

if I where to make the nose rib x=0 and y=90 instead of 80, and do the same to the rear root rib, it would look more like the drawing of the nose and rear rib together, on pg 75-wa-1

Any suggestions…

Wing progress

Last week I disassembled the wing, deburred everything and primed the joint surfaces. 

I decided to rivet the rear structure - rear spars to rear ribs, rear strut bracket etc - but not to rivet the ribs to the main spar at this stage, in case any shims were needed to pack out the nose ribs.

Riveted the lower trailing edges and lower rear skin to the framework, turned the wing over (carefully!) and clecoed the nose ribs back on.

This week I clecoed the nose skin…

More CH750 Spar Work

Another decent weekend and I was able to get out in the garage. Got the lightning holes drilled for the spar. Also got the spar tip and the spar root doubler cut. Finally, I was able to draw the pattern for the spar web doubler. I expect I will have to machine cut it. I bought some cutting wheels for my dremel tool. Will see if I can do a rough cut with it and then file it down to specifications.

GoPro wing mount

Has anyone attached a GoPro camera to the wing of a 601 XL? I am looking at ways of doing this - I hear the 3m adhesive mount will be strong enough but it would probably take off the paint when trying to remove it at a later date. Any advice?

Wing Spar Work Continues - CH 750

After realizing that I cut the original wing spar form from the wrong thickness metal, I was able to take advantage of a warm Saturday to cut a new form with the correct stock. I was able to use the original stock as a guide as I cut the form with an Olfa knife. It wasn't easy but I got a straight and clean cut. The form in the photos look ragged but I left the protective coating on.
