is there a way I can test my hump packs?I got a feeling from sitting in the garage over winter there not holding 1600 anymore.
Using your battery charger, discharge it to 4.5 volts and then charge it at about 0.5A and see how many mA it takes to charge. It should be close to 1600. If it's less, you might need a new pack.
It's never too late to have a happy childhood.
I needed a new one after winter. My hump pack from the previous year only lasted 1.5 hours
Easy, put it on the truck and see if the steering servo has enough power to move the wheels for a few minutes...
