This subject of Tx's getting damaged by being switched on without the aerial extended keeps on coming round, especially related to simulator use where you power the Tx on but don't normally extend the Tx.

One commonly suggested solution is to remove the Xtal so that the RF circuit won't resonate and try and dump a load of power into the collapsed antenna.

However, think about this a bit more... Hands up ANYONE who hasn't at some point been fiddling about with a servo setup or testing a motor one night and accidentally left their Tx switched on ALL NIGHT? OK, how many people have had their Tx damaged by this action? Exactly - no one.

I'm sure the Futabas/JRs/Hitecs/Airtronics of this world consider this possibility in their designs and safe guard against it or they'd be seeing mountains of returned, toasted Tx's !!
