Since Eggtimer altimeters are cheap and I like building them I generally use a dedicated altimeter in each rocket, In face I tend the build the eggtimers first then look for a new rocket for it., I have more altimeters then I have rockets to put them in.

I have an old North Coast Rocketry Enerjet 2650 clone and the Rocketarium Trident T263 is also a clone of the 2650.

I couldn't disagree more. A browse through the 2022 catalog shows many new challenging kits that have introduced or released since 2019. But Estes like the rest of the hobby industry has to find a market to stay viable. A stroll through the nearest Hobby Town (I don't consider Hobby Lobby a...

Acetone, but make sure it is 100% acetone, some acetone has 10% water in it.

If you are not going above F the 40/120 case is the way to go. It more different reload options then any other case. I use mine more than any other reload case I and I have a lot, my casings range from 18mm all the way to 54mm, but I have not yet flown the 54mm casings

I never had a problem with A3-0T when they were available, they have plenty of thrust for a booster.

When I was practicing for S8 RC rocketglider for the World Championships I would take D12-3 and scrap out the ejection charge, no glue needed. They worked fine that way, but yes it is not recommended by the manufacturer so not certified.

Estes started die cutting some time ago. The 1974 Custom Parts Catalog Custom Parts Catalog (spacemodeling.org) included die cut fin sets, but Estes has switched tp laser cut fins, much better then the often crushed die cut fins. I also started when Estes gave you fin patterns and you cut your own.

The Space Plane ejected the engine for two reasons, to make it lighter and so that you could hold the elevators down during boost. One the engine ejected it released the elevators to flip up to flight trim.

Everyone has struggled with escape tower on that Mercury capsule since the days it was produced by Centuri. At least it was composed wooden dowels like the original Estes capsule

I think the threading is different between a 29/40-120 and 29/240 he may have damaged the casing forcing them on.

the Biggest I can recall were some A Supperocs built for NARAM-22, over 20 feet tall, I don't remember exactly, But I don't recommend any that long they went about 6 feet in the air and had to use boosters, because 2 second delay was too long.

BMS will be there all week (up to M if you need larger let him know beforehand). Apogee will be there, if they don't have what you need at the range they can bring it the next day, since they are located in Colorado Springs, and Moto-Joe will be there for the weekend...

For my competition gliders I use contest Balsa (less the 4 lb/cuft for the wings) the lighter the better, Hard balsa for the fusilage and c grain medium balsa for the tail feathers. Then finish by painting with 50% thinned Sig clear light coat and covering with true Jap tissue.

Estes had you make a clear tube of flexible plastic, by wrapping it around the tube, then you glued the clear fins to that. If your going to be at NARAM I am planning on refurbishing the one that I built more then 40 years ago and flying it at NARAM

At one time it was included in the catalog as a center insert. Starting in 1969 https://www.ninfinger.org/rockets/nostalgia/69est048.html
