Deathbunny, limp servos when off, that has nothing to do with being digital. It is often from the coreless or brushless motors being used. Good analog servos will do the same thing. Cheap digitals that use 3 pole motors generally won’t go limp when off.
Ahh that makes sense. All the non digis I have used were cheapos and the digis all pretty high end. I just assumed it had something to do with them being digi, didn't realise it was different motor types. Thanks
