Depends on the dehydrator, but 3-4 hours of smoke and 8 hours in the dehydrator, give or take a couple.
I think with any kind of jerky the less fat the better. Your ultimate goal is to remove the moisture from the meat. If you like it chewy, take it off a little sooner. Ground jerky will start crumbling if you go too long. Snack sticks take a little bit longer. But, it's all still tasty with the right seasoning! I'll pick at a batch the last few hours until I'm happy.
One last note, I'm a pepperhead. It's never to hot for me...I add ghost or habanero pepper powder to my marinade and put a healthy dose of crushed black pepper on top about half way through the drying.
