Perhps you can answer this for me 8scale. It is my understanding that the brushless motors are more likely to incur damage from vibration in off-road racing situations. Given this and the fact that brushless servos tend to be larger than their coreless counter-parts, how do you justify the use of brushless servos in off-road surface applications? Are these drawbacks less significant than detractors are willing to admit? I also understand that brushless will run cooler than a coreless servo, to the point of no longer requiring heat-sinks in some cases. Is this enough to justify their use?
