Yep it is a pretty serious position to take. But this jet crashed 100 metres from the boundary to an the local air museum, full of families enjoying their Sunday afternoon. There was no one where it actually crashed, but on a different day there would have been a fair, again with families having a good time. To make it clear, this crash position was about a mile away from the flying area, well beyond the normal flying boundary because without a fin the model was out of control. The pilot was complimented for struggling to avoid crashing within the boundary of the air museum.
Serious! I'll tell you what serious is. Serious is standing in a coroner's court explaning to greiving relatives why their loved ones were killed by a model jet. That's about as serious as it gets Mike.
In comparison, banning our members from using a perfectly good servo (I use them in gliders myself) in a situation that the manufacurers never designed it for, and for which we have evidence it is not suitable for, does not really compare now does it?
Members are quite free to use this servo in non jet applications where we do not anticipate problems.
