Yesterday, I tried my 1st launch since Aug. I had 2 out 3 ignitors fail. Removal of the ignitors revealed they broke. Now when I did my 1st launches in July and Aug 3 ignitors failed. So out of 5-6 launces I have had 5 ignitors failure. Yet as a BAR 15-20 years ago I had maybe 3 failures (broken) in 2 dozen flights. Now I know as an engineer wire will not degrade over time, unless you use it/bend it etc. I installed all ignitors at Home, Engine vertical on a bench, being careful and insuring completer insertion. Is it the Plug? When a newbie had issues earlier this year, one response was to forget the plug and tape,. I defended the plug by saying they are great and very few issues. So much for that opinion. These are the old black pyrogen ignitors and I hate wasting them. 2nd Question- since most clubs use car batteries has anybody just gone back to nichrome wire (Black Powder motors), make a loop in the wire, insert and use wadding or tape to hold. Nichrome works perfectly on 12v lantern batteries. If yes any idea of the gauge?
Estes, please ship redesign ignitors as promised.
Unrelative topic...my one flight was a Black Brant II on a B6-4 engine...beautiful flight to over 300 feet (guess). The B4 engine I tried in July....was underpower. So go built a BB II and fly it on B6's and maybe a C5 and forget what used to be said.."Launch it and lose it"...on a D engine.
