+1 on that Keith! It's less of an issue if the caller and pilot work together all the time where pilot and caller both know the plane and all its systems well. But that's certainly not the case with most of the participants at the paltry 3 competitions I've been to. We find a willing pilot from another class (or even our own class) to call for us. Now it's even worse -- the caller doesn't know your bird at all, you're distracted after competing and your caller is hurrying to get ready for their round. No one is thinking about ensuring the plane has been rendered fully safe. A simple plug removal (or re-insertion of a pin flag) is easy to do quickly and takes < 10 seconds to explain to a caller.<div>

<p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Dave, you're points are correct, but you're not taking into account a malfunction of the speed controller itself. They have been know to malfunction, so the safest approach, as Earl suggests, is to assume that anytime the battery is connected to the controller the motor may go to full throttle. Until you unplug the battery the thing is hot and dangerous regardless of your fail safe or switches on the transmitter. <u></u><u></u></p>
<div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">Regarding pulling the disconnect (whether under canopy or via external arming pin), step over the model between wings and stab (just like we used to run up the glow models) and reach down to pull the plug. If it goes full throttle the back of your legs will stop forward momentum.<u></u><u></u></p>
</div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">I see far too often that people switch off their radios with the plane in a potential dangerous position.
