1. My Quest launcher with a fresh 9 volt won't light them either.
2. My 12 volt system melts the wire off at the clip attachment points.
3. If I cut the brown paper binder and separate the wire leads I have a better than 95% success rate with 12 volts. All my good flights this summer have been with snipped new style igniters. Can't explain why, but it works.
Great looking Thunderchief!


You'd likely take the ThunderChief comment back if you were as close as I was to it on Saturday, but thanks. It was a frustrating build. The tube connectors were ill-fitted and very noticeable with copious amounts of sanding. While I was working on it, someone spilled a glass of water across the kitchen table and it soaked everything sitting nearby, including the instructions and the decal.
As for the igniters, I'm going back to dipping my own, likely later this week. I've used up all the ones I did previously, and I had great success with them. Might try using some of them dipped in the melted ping pong ball solution just to see how they do nekkid.

The 9V and the current “starters” are a bad combination for sure. The little 9V battery just can’t muster much current. As you learned, if you hold the button down long enough it will eventually get hot enough to light the motor if the bridge wire is tight against the propellant.....

For a handheld controller the good ol’ Electron Beam (or a Solar Controller) with four good AAs in it (Duracells or such) is much more reliable with the soon-to-be-reformulated Estes “starters”.

I suspect all of this is no surprise to you, however.... Interesting Erik’s bit about separating the leads. Maybe that helps get the bridge wire consistently tight agains the fuel?

The old four cell was what I tried to use previously. No joy on that front whatsoever.

So was I. We have a club launch this coming weekend, but it's pretty iffy as to if I'll be able to go or not. I had the need.

It was actually a squeal, followed by "OHMYGOD, WHAT WAS THAT?", so there's that.

What a great post (apart from the initial launch issues/frustrations)!

Good looking models, a pretty fall day, suitable venue, and even a semi-interested audience. Can't ask for much more than that for yourself, and for those for whom you became an informal model rocketry ambassador.

Pity that even more interest was not shown by any of the potential STEM students out there on the field...

I typically launch with the Tripoli guys which isn’t a problem of any kind, they always put up a multi rod LPR pad and everyone seems to get a kick out of all my smaller rockets going up, but next time I have a chance to fly with the NAR club I think an all Semroc & Centuri fleet would be a hoot! I have both but more Semroc than Centuri. Looked like a fun morning - nice pix 👍

Estes has promised improved starters - mentioned late last year before the pandemic heated up and again during vNARAM...hopefully they actually are improved and we start seeing them soon.

At ejection there was a flurry of activity aloft, and when the dog barf settled the Vector V came out of the cloud clearly tangled in the shock cord and Kevlar. The whole hot mess landed hard in short center field, and when I got to the tangled pile I found one of the fins had broken off in the melee. I walked the whole outfield looking for the bright red fin, but found nothing.


Good looking Vector V - mine needs seams filled and painted. One of the kits I wanted as a kid but never bought for some reason. I did build a fiber fin Moonraker but don’t remember if I flew it more than once. Nice thing about loosing a V V fin is it’s fairly easy to replace - card stock is cheap and plentiful!

Hey, at our age, I'll take what I can get.

Being a Semroc kit, I think this one was balsa, but that shouldn't make a difference. Next time it flies you won't know there was an "event".
