I'm getting ready to fire up my savage x for the first time and I'm wondering about the glow plug ignitor and hump pack charge times? I know there's smart chargers and all that, but I just have the wall plug in chargers and I want to run it for now. How long do I charge the HPI 1200mah hump pack for? Also how long do I charge the glow plug ignitor for? I received no charging instructions with these items. I don't want to over charge them and ruin them! Thanks in advance!
