Hello all, and thank you in advance for the help. I inherited a nitro rustler from a friend. I donít have a hump pack for it. Iíve been running 4 aa alkaline batteries in the rustler. Running the stock servos. How long will these last before they should be changed? With the lithium aa last longer? How long? Whatís the best overall option? How long will the same batteries last in the controller? Thanks everyone!
