I've made a bunch of clip-whips, I had to, because I always forget to get them from the pad, too busy chasing the rocket.
clip-whips work great but I think the Q2G2 is the best thing in igniters, ever. they are low current, so wire them in parallel, and even the crummiest clip leads on the crummiest old club battery will work.
I made a 7x18mm BT80 model of the rocket on the cover of Alex Ryder adventure "Eaglestrike".
on that rocket Q2G2 igniters (in parallel) always got all 7 motors lit, every time. 7 ejection charges is a lot for thin cardboard so it only flew 7 or 8 times before burning up.
gonna build another one. there is nothing like the sound of BP clusters, and it's beautiful at dusk and at night.

Unless you're planning on just launching one rocket with a cluster of model rocket motors, the best technique is to create a whipclip with several leads. I've made these for up to 5 engines. Tag or color one alligator clip of each set so you don't get them mixed up on the pad.Also, provide some slack so the when the first motor lights it doesn'tpull the rest of the igniters out before they light. You can also usea small stand or stake and fasten the wires up a bit; again to providesome slack as the rocket moves up the rail/rod. Then, during launch ask the LCO to push and hold the button until the rocket clears. Quest igniters are alright. The tips are fragile and the way they are secured in the nozzle (with the small tube) can be difficult to get them to stay. The nozzle on Estes C engines is small compared to A's and B's, so inserting the Quest igniter into the nozzle with the tubewill be difficult. Hey, you could glue it in. That would be cool; likea giant noddle being blown to bits with an M-80! Best to use an Estes igniter with the correct plug, check the resistance after installing the igniter, and use a whipclip arrangement. And, remember to recover the whipclip after the launch. In the past, I've made whipclips using 20 Ga stranded wire and small alligator clips from Radio Shack. Chris, other than the joke, did anyone respond to your question aboutwhen set-up starts? Usually, it's when the trailer arrives, and people start setting up. If you haul the trailer, it would start when you sayit's going to start. ;-) Richard ------------------------- To: roc-chat@xxxxxxxxxxxxx Subject: [roc-chat] Re: Clusters From: Chris.J.Kobel@xxxxxxxx Date: Wed, 29 May 2013 08:17:17 -0700 I believe TR-6 discusses clustering techniques.

For three??? Nah. Waste of good black powder. :) Now for 12... now yer talking. Chris you can find the old 60's tech report from Estes on clustering. It's simple and shows the wiring of the estes 'starters'. However I two have heard the Q2G2's are great for clustering. They fit just fine. Instead of using the plugs you use either the protective tube that comes with them, or little balls of wadding stuffed behind them. --------------------------------------- Jeff Gortatowsky, Redondo Beach, CA | Twitter: JeffGortatowsky | Yahoo: indanapt "(Scientific) Skepticism is not a set of beliefs, it is a set of methods for asking questions about reality." -- Doctor Steven Novella ------------------------- FROM: Lakestake Rocketry <lakestake@xxxxxxxxx> To: roc-chat@xxxxxxxxxxxxx Sent: Tuesday, May 28, 2013 2:58 PM Subject: [roc-chat] Re: Clusters Nobody going to chime in on flashpan ignitiin?

When using C-size motors how do you wire them as a cluster? Meaning...since they use those tiny little wire igniters how do you get them all wired together? Thanks.
