Dual Deplyoment Tips Needed

I make ejection charges using Orxl electric matches. You can find them at your motor dealer at launches. You take a small rubber grommet and slip in over the white end of the electric match. or just biuld up hot glue instead of the grommet. grommet just for neatness.

You then Hot Glue Gun the match/grommet into a tube about 2-3" long cut from the tube on the end of a pants hanger. To fill, you pour your black powder in the tube, and pack the tube shut with standard Dog Barf recover wadding. You can also push a white tape disk into the tube to cover the end of the dog barf if you wish or use masking tape.

Mark Palmer over fills his and his rockets sound like cannons in the sky !

to qoute him: "To Be safe on recovery, you either want to Blow it out, or you might as well Blow it up." all kidding aside, at least it will deploy that way, he he...

Couple tips on building the Sudden Rush.

It's a whole lot nicer and easier to use a slim-line boat tail motor retainer. Hawk Mtn. is where I picked one up and it's much nicer than trying to rig something to hold in your motor. Also, make sure to use a motor tube that will go up high enough if you're planning on using the Dr Rocket 38-54 adapter ends.

Another thing, when putting together the CPR system, do it as the instructions say. Don't screw in the caps, and then back it off thinking that tighter is better. Will cause problems with the O-ring when you tighten it up way tight. Because of the limited amount of space, it's advisable to use kevlar shock cords with kevlar protectors. Giant Leap can hook you up there.

As for the electronics, personally in my opinion, don't mess with a switch. Hook up your wires for the switch and then thread them out of a hole. When you're ready to arm it, simply twist the wires together and tie a knot close to the frame. Works like a charm and I've never had a problem using this method on co-pilots, RRC2's, or RDAS altimeters.

Another note, when hooking up your e-matches (Daveyfire N28BR), make sure to point the unit away from you. I had a freak incident where the capacitors didn't bleed off excess current and fired an e-match after I had been using the unit to just record altitude in a previous flight shortly before.

Good luck. Of all the rockets I fly, my Sudden Rush is my favorite. A J420 puts it up around 3,400'.

Here's a couple shots of mine:

Show Off!! Man, Boomer, that is a great looking rocket. I also have a Sudden Rush and I agree it is a really nice kit. Make sure to download and read the PML Building FAQ from their website. Also dry-fit everything several times before you actually build it. I agree with Boomers suggestions.

Boomer - do you have gold in yours weighing it down? My SR will hit

4500 - 5200' with a 5 grain Pro-38 motor (depending on grain type). Be aware that the Kwik-Switch motor mount does limit your motor choices somewhat - I can't get a 6 grain Pro-38 motor to fit in mine. On the other hand, I put a Slimline retainer on the 38mm motor adapter which works great with the boattail.

Good luck,

I build all my rockets like tanks. Is 6lbs. Can crank on it all day with a K1100's and not even phase it :)

It's wrapped in fiberglass, reinforced fin fillets with carbon fiber, doubled up bulk head sealing the motor tube, foamed fin can, etc. etc.
