Upgraded a Modulus ECS-10 with these flywheels (also using meishel 2.0 motors, OFP cage, rewire and volt mod @ 7.2v NiMH) and the performance blew me away! They're a quantum leap over the standard flywheels! Do not underestimate the performance gains you can achieve with these!
brill bro 11/10
These things are a quantum shift from the standard wheels. Running RM2 motors with standards and 3 li-ion (don't care have a stash of 20 of them) the noise is just ridonculouos with these little gems it is so quiet, no one expected the speed these put out with the noise they made 11 out of 10 - can we get them with angled grooves to impart a spin ??
