A good quality 31 mm diameter CNC cut firwall made from strong 2 mm thick glass epoxy sheet, ready cut for Powerline type gearboxes/motors.
Available in various diameters, though it is easy to reduce the size if necessary. To attach this firwall to carbon/Kevlar/glass fuselages we recommend JB Weld as it does not soften with temperature.
