alright delete this thread before word gets out to everyone!!!! I dont want hobbyking raising the prices on us. My son and i plus a few other guys run the A spec shorties and saddle packs. even the zippy batteries have worked well for us. on most of the items even if you get a bad apple its still cheaper to buy the second one than buying one of the big named components, and until one of the big manufactures comes knockin to run their products ill be using Trackstar.
