I noticed the other day, to my surprise, Hobby Lobby in Manchester, NH, is carrying Estes Rockets, including the Pro Series II. The benefit of this is, generally, they have a coupon for 40-60% off one item, which you can use once per day.
Thursday I was able to pick up an Estes Leviathan for $36, along with a few F and G motors they had in stock ($14 for the F's, 16 for the G's). This is my first venture into composite motors, I figured I'd bring it up.
Are there any local vendors in Southern NH/Northern MA that have higher power stuff available? I remember there was someone who was selling motors at the Amesbury launches.
