Hi Fellow Summit Owners!
I just made the transition from RC Helis to RC Trucks and the Summit is my entry to this side of the RC hobby. While I was waiting for the Summit to arrive at my doorstep, I got a bit anxious to get it up and running right away when it arrived. I had two Dewalt XRP DC9096 18V NiCd packs (15 cells each) that I use for my impact wrench so I harvested the NiCd cells from one of them and made two 2500mah 7 cell packs and charged them up. As soon as the Summit arrived (and the UPS guy was a bit jealous and asked if I wanted to refuse the package... ) I soldered the additional Traxxas connectors I ordered on the NiCd packs, plugged them in on the truck and fired it up. And then I hit the throttle! Awesome!!!
After running these a few times, alternating between the stock PowerCell 7 cell 3000mah packs and the 2500mah Dewalt XRP NiCds, I'm getting longer runs and more power from the Dewalt NiCd packs. I guessing the NiCds have a lower impedance (they were used to remove lug nuts on my full size truck in their former life). These are Sanyo NC-2500SCR cells.
Yeah, I know NiCd is old school, but I thought it interesting that they seem to outperform the stock PowerCells. (3000mah NiMH vs 2500 mah NiCd).
This is an awesome truck and forum! Can't wait to get this thing upgraded to brushless and LiPo (when funds allow). I suppose I'll start with the Dewalt motor since I have an old 12V Dewalt drill laying around. Looking forward to lots of fun on this side of RC "land".
