....but but... I like dangerous tools :) Well done! I think the idea of only cutting the top layer is really good and kind of counter intuitive but from what I see I like what you are doing better than if the material was completely cut through.

Thanks for watching!

Great video, but you have to add the maiden flight at the end. Really kills the video without it. Cheers.

[@reedinspace2286]

Thanks for watching. I'll post a video soon. I have to wait for the weather to cooperate!

[@edwarddranetz171]

Very nice, can you do some vids on cutting technique and design mods..🛩

[@reedinspace2286]

I'm definitely open to ideas for videos. What specifically did you have in mind?

[@Droanly]

Ok so you can't cut foam board complete with a diode laser. I wonder if the new 70-watt modules can cut it completely.

[@reedinspace2286]

I'm thinking it has more to do with the wavelength of light than the power. I can blast through black foamboard easily on low power. More power with a diode will probably just melt the polystyrene. I wouldn't mind trying though.

The adams ready board flight test foam board is stronger and water resistant. much better then the flimsy white board

[@reedinspace2286]

Yep. I agree.
