RE: Is a person who turns their radio on without the pin responsible for the cost of the crashed model?
Yes they are. If you have a frequency control board there is no wiggle room. It a simple case of right and wrong. If you are wrong your wrong- no if's, and's or but's.
If you allow a person one honest mistake - why not two or three - they didn't mean to do it!!
We all need to be responsible for our actions-right or wrong!!
