Am I not seeing this correctly or is the right side of the fuselage frame not properly triangulated? Picture an upward load at the front landing gear attachment; the door sill area is basically four-cornered. I would at least put a full sized gusset over the whole area or add a diagonal.
Correct, but that's how the plans show the door area, also as this a 'scale build 85%, the door is smaller than it looks, all gussets on this build are twice as large as original to give bigger bond area, and there is a gusset on the inside of the door opening, it's not perfect, but that's what I'm working with.

Spent the morning in the hangar, weather here in the UK nice and warm for the time of year, Managed to bond in the 'hardpoints' for the lift strut and jury strut onto the front and rear spars, and fixed the wing root attach brackets to the front spar, plan to get both wings finished by month end, then can mock up for control system to ailerons, that are not built yet. More pics to follow in the next few days. Now have a choice of engines from a ROTAX 447, ROTAX 562, or a Hewland 3 pot from an ARV, Hewland looks good at this point.20200725_125508 (1).jpg

You learn more every time you start on the next phase of the project, I forgot to pre drill ( undersize ) the nose ribs. So when I went to drill through the rib and skin the drill started to wander and my line of rivets will be slightly 'off'. But as this is the first of 6 nose skins, 3 per wing, so now the next five should be much better and quicker fitting. Had hoped to cover by xmas, but will wait until early spring now, but rig the a/c and finish control system, morse/teleflex cables.

And thank, Alan, so much! Wonder if the issues were the same back then.

Spent a few hours down the hangar this week, and finally finished the Leading Edge D-Box, fairly happy with the results (first time wing builder), but the nose profile was a bit of a bugger as the ribs themselves were not that well made, so took a lot of 'adjusting', Went to take some pics, but battery on camera died, so that will be done Monday, Weather only 2-4C so bit chilly, but at least not bonding again, yet !!!!

Guys, just had a mad idea, that on paper seems to work !!!! As the hangar is looking like a tip (Dumpster in the USA) we plan to have a massive clean up and clear out the area that the airframe is sitting above. Plan is to store airframe upside down, but this allows me to rig it with the wings at ground level, saving the hassle of putting up high trestles to support the wings, but the major benefit is I can use cable/string to get exact strut lengths, as they will be in tension. I've just bought a laser level too , so can sort out washout,dihedral,alignment,etc, and this will all fit under all the other aircraft as there all high wing. Simples.
