No, that's been tried and it doesn't work well for multicopters. * They're only effective from quite some altitude, much higher than you typically fly multicopters * They'll still just soften the landing somewhat anyway * Multicopters are much more fragile than, say, EPP planes, * You have to make sure they don't get caught up in the props * Also you need to find a reliable way to trigger them -- for model aircraft in general and multicopters in particular, humans are way too slow and sudden high accelerations in arbitrary directions are common for multicopters.
