My son received one of the Estes Hydrogen rockets as a gift a while back, and we finally got around to trying it yesterday. Everythingseemed to function fine, but the rocket wouldn't launch. I'm guessing that the igniter is bad, because I could never see it glow red (as the instructions state). Is the glow visible during the daytime? Anyone have any suggestions on debugging this thing? Are there replacement parts (e.g. the igniter)? Estes is shut down until the new year, so I can't ask them.
