got my blitz tonite, and can't wait to run it this weekend. i am correct in assuming it is lipo ready out of the box?? eventually i want to go brushless, so if i could buy one battery for both now and later, could you guys recommend one. the brushless systems i am looking at is the castle creations mamba max pro 5700 system or the hpi flux 5700 system. any help would be great. thanks
