You are correct sir! Just looked it up to be sure and these are High Power capable! :cool: :clap:
Ed this gives you an additional group to market these to.

I would suggest that you do what you can to "tighten" up the fit between the coupler and the body tubes. The push pins will hold the coupler solidly in the fin can. Use strips of aluminum tape until...

I had forgotten you had the Aeropoxy. If you have the Bondo kit I am pretty sure you can use the any resin with the fiberglass in the kit.

Depends on what brand motor you are using, Aerotech/Estes Pro or CTI. CTI reloads are pretty reliable when used with the supplied igniters. Aerotech/Estes Pro single use or Aerotech reloads depend...

Madcow has some really nice tail cones too.

+1 on this.
Get some hobby 30 minute or laminating epoxy from a hobby shop or from an internet store. You and your family will be glad you did.
I use AeroPoxy and you can barely smell it even when...

I am going to try these weld nuts from McMaster-Carr in my next ebay.

I hope that by alining the tabs in a Fore and Aft configuration there will be no need to bend them.
They come in...

I lined the inside of my coupler with two wraps Kevlar for added strength and did the balloon thing too. :D
My Endeavour puts all of the...

If your club is like most you have different pads at different distances depending on installed Impulse and rocket complexity. I would think if you flew from the "M" pads it would be much safer than...

I was told that some Fiber Glass airframes were made on tapered mandrels not straight like paper tubes. So the ID can vary from one end to the other. Plus there are always manufacturing "tolerances"...

I already have a Slimline 38-to-29mm adapter but mine will do both Hobby line and High power. This will allow me to dedicate that one to High power only.

Not from me. I am impressed that all three certification organizations are pooling their resources!

Does OR compensate for Base Drag? Base drag will make a short fat rocket more stable than it looks. I know with RockSim there "cheats" that will add it into the simulation of short fat rockets. I...

I like to as far aft as I can with the lower button. The forward button ends up around the forward end of the motor mount. If the mount is really short I try somewhere around the CP If you end up...

If the forward closure/bulkheads for the Loki motors are threaded couldn't you mount a bulkplate far enough forward of the longest motor you plan to fly and use different lengths of all tread for the...

I have used the Panic beepers and the magnetic window/door alarms with no problem. Mine are tied to the recovery harness and activate when the parachute pulls the pin out or magnet away on...

Mount a short section of tubing that will fit over the OD of the switch and is long enough to almost touch the ID of the AV Bay. This will guide your screw driver to the target.

My 6" Ultimate Endeavour Phred on an M3100WT 10-24-12. I thought I had already posted this.

Especially since I beat this deceased equine forever. :facepalm: Need to go take my meds. :neener:

I have two RRC2 Minis, a Raven 2 and a Raven 3. A Mini and the Raven 3 stay in my L3 bird the others move around. I also plan on buying at least one of the new RRC3's. The current number of flyable...

I could not find a listing for a Long delay for the I154J any where I looked. No vendors and nothing on the AT website.

Scott my advice is worth what you pay for it. Sim it with both chutes and above all consult with your TAPS.

Mason
AT does not list a delay grain for the I154J that is "full length." Check this drawing of the I154J-M.

Are we talking Cub scouts or Boy Scouts?
Get parent involvement with the build phase if at all possible. One it will let Mom and Dad know what is going on and two you may find resources you didn't...

According to the AT motor assembly drawings for the I154J Short and Medium delay the spacer would have been 0.188" for the short delay and 0.063" for the medium.

I drill a hole in the bulkhead large enough to insert an 8-32 well nut. I build the charges, pass the wires through the hole, connect them directly to the electronics, insert the well nut and...

I figure you can get one in there but it looks like there will only be about 16" of airframe to put the chute, harness and protector in.
I also questioned if it was necessary especially with a...

Looking at your specifications I am thinking an 84" (7') Rocketman parachute might be overkill, especially in Argonia with an all fiberglass rocket.
His descent rate chart shows that with a...

Speeding up the cure is one thing but increased strength is the other.
When I was making the fin stock for my L3 rocket I layed up, vacuum bagged and cured four 12"X24" sheets of 1/8" nomex core...
