Redesigned my Lazy-J and went out and maidened it this evening. The original design has an under camber wing like the FT Simple Scout. For the redesign, I set up the wing similar to FT’s Mini Tutor. With a 2205 motor and a 900 maH 2S battery it jumps right off the ground. It has great handling for a three channel airplane, and it was even zippier with a 3S battery. Sadly, it weighs 298 g with the 2S battery, so it needs a remote ID module. I suppose I could make it smaller to get it under 250 g.

If you want to cut weight to stay under 250g there are a couple ways to do it.
The least impact on appearance to get a little weight out is by peeling the paper from the inside of the fuselage. The paper inside doesn't add much strength in most designs. By my calculations, the paper on one side of a sheet of Adams foam weighs about 8 grams per square foot. So it's not a lot of savings, but it can help.
In most planes, though, the biggest weight is the electronics and battery. If your motor and battery are more than sufficient, you could always go for a smaller, lighter motor and a smaller battery to match.
And the simplest, quickest solution but will remove some functionality is to remove your landing gear.
Even with remote ID, I bet it's a blast to fly.
