Foamo - a mega brushless flywheel select fire blaster!

Update 11-02-2026: Fixed lipo door and lower back heat inserts pockets.

Here is my take on a brushless mega blaster. It does around 130 fps at 25k rpm. It has select fire, semi and full auto. It also features a pre rev mode, just to make the spinup even a little faster.

It is the first blaster I've built with the Mega Brushless Core I've designed, so feel free to start designing your own mega Brushless blaster shells with the core.

Spinup time is around 130 msec at 25k rpm, but can be substantially lowered to around 80 with the pre rev mode. 

I'm using the m'f'n stock available on thingiverse to house an 1800 mah lipo. You can squeeze an 850 mah 4s in the back, but these tend to get a little warm, which I personally do not like. But if you're okay with that, do it. All at your own risk ofcourse.

Please note, the original mega mags are not compatible, due to having having weird plastic lips ;) You can grind those down, but I would recommend using the Titan magazines instead:
