Been gone for a while and sub 250g question.

[Indy durtdigger]

Hello all. Haven't been around for a while and as with the way of things my flying hobby got back shelved for a bit. See a-lot of new names as well as a forum makeover.
My question about the weight limit on the planes that won't require the upcoming RID or other permits is as follows. I've been poking around the forums off and all on day and done some searches but have not been able to answer my own question. Has anyone began compiling a list of build plans for planes that fall into this category? The way things are going these will be the only way some of us will be able to stay in the hobby for a while longer at least.

I haven't seen a list compiled yet. I can safely say that without modification, all or nearly all of the FT planes are too heavy. I've been looking more at smaller builds recently as they fit my flying fields a little better.
To that end, I just finished a little build based off the Phat Phil; a little balsa plane from Flug Modell. I scaled mine down 80% and built it out of 1/8" XPS sheet. Came in at 100g.

I've been looking into the XPS material. There is a You Tube channel I watch (NUMAVIG) that makes planes exclusively out of that stuff. Makes lots of minis that should work quite well. Last plane I built was a Crack Yak styled park flier that's sub 250g but barely. Enough so that on someone else's scales it may not be.

A lot if early electric foamies were made out of 1/4" "fan fold" insulation foam. For mine I took some 1" thick pink insulation foam and shaved it into 1/8" sheets with my wire cutter. Worked great. NumaVIG was definitely an inspiration when I was looking for ways to build light.

I’ve designed a little racer from that type of foam that can be built under 250g. I’m afraid I’m trying to sell the plans (but cheaply) as I lost my job last year and I’m trying to make my hobby cost neutral. There is a build video as well as plans.
