Speed Passion V4.0 Stock brushless motors
New from Speed Passion come the V4.0 Stock electric brushless motors. Designed to meet EFRA, BRCA and ROAR specifications the motors build on the V4.0 Modified series in terms of can design but they offer improved cooling vents for better heat dissipation and lowered running temperatures. Taken over from Modified motors is also the new end bell design that incorporates a plug-in system using bullet-type connectors over the standard solder tab design used by other companies. The motors come in a range of windings including 10.5T, 13.5T, 17.5T, 21.5T and 25.5T variants.
