<DIV>There is some loss, energy that's released as heat from the mounts movements, more with softer. The percentage loss is pretty small, but can be measured in the higher rpm ranges say 15K to 30K range. The measurements I made were in the 10K range and weren't obvious within the limits of a model tach (Futaba 8), probably even less important in the 8K range we now operate.</DIV>
