Brushless outrunner electric motor firewall for use with most motors with a 16mm x 19mm bolt circle for direct mount, or 34.5mm X-mount bolt circle. 16mm x 19mm mounting locations are slotted to accommodate any motor orientation. Ribbed flanges provide extra surface are for adhesion. Can be hot glued directly to foam board without the need of adding tape for reinforcement.

Can be used for most Flite Test Simple/Swappable series models using FT Power Pack B and Power Pack C electronics.

Can be printed in PLA, but I highly recommend using PETG or other stronger materials (ASA, ABS, Nylon, etc.) for improved strength and heat tolerance.
