Got the flap mounts designed and printed. Did the outer ones today, I'll print inners tomorrow. Wasn't quite happy with the inners but they're good to go now

Not much done the last few weeks. Been out if town a lot and work got intense too...

But today I got a new nosegear plate cut. Hopefully more progress tomorrow.

Got the hatch covers cut along with the pieces that will become the "spludders". Plan is the bag the spludders halves to a piece of window glass with low vac pressure so as not to crush the foam - EPS doesn't do well with high vacuum...

Also got the main landing gear mounting plates cut

working on the back end a bit - lots of work goes into the CAD for this model before it happens in reality... but i did take some screenshots

clean and dirty flight modes depicted from several angles. didnt set all the colors right yet...

Little bit as often as I can...

Got some new flap hangars printed and fitted. Thanks Mike for printing them out for me - he printed them out of carbon filled PLA - should hold up better to heat, and they are printed slightly hollow - so they ended up about 30% lighter too.

Mike is one of the guys printing complete 3d printed planes, on the bleeding edge of the hobby, and just happens to be on my way to and from work here in San Diego. He will print you parts or a complete airframe if you like, hit him up if you're interested. Super cool stuff, the future of scratch building really, or at least a large part of it.

Mike's handle here on rcgroups is "electric-2000"

Finally got the flaps sanded in so that they retract all the way up.

Not much progress this weekend. Was at the shop quite a bit but we had some major cleanup going on. Time to purge some stuff.

Hi !
Are you using a 3D mill to "sculpt" so clean foam pieces ?
Impressive work, congratulations

As PittSpecial, I also can't wait for the maiden

Wow this is one of the cleanest and professional foam build I ever see, and the aircraft locks fantastic.
The only sad part is that the build process is difficult to replicate because the lot of machinery involved.
Anyway a pleasure to follow

Btw, Can you post more details about flap mechanism?

yea im using a CNC router for cutting the foam parts out - the process goes like this:
design plane
divide plane into chunks that will be easily machinable on a 3 axis CNC router
cut foam pieces on CNC router
assemble chunks with stiffeners / spars where necessary
sand parts to match eachother (should be pretty close already tho because CNC routers are pretty accurate
apply lightweight filler
sand smooth
glass with whatever weight cloth is appropriate (i used 4oz for most of this plane, which is kinda heavy for this size airframe... but i do NOT plan to be kind to this airframe)
sand
fill
sand
prime

theres still a lot to do for 3d printed components too... but im working that
