Default Estes Majestic PS II E2X Kit

I have assembled an Estes Majestic kit.

This is the second Estes PS II E2X kit I have finished.

It was easier to assemble than my previous PS II E2X model (Ascender) due to the fact that the fins halves are already glued together.

I assembled the model with CA and 30 minute epoxy adhesives. My only alteration to the kit was the addition of a Semroc ejection baffle (EB-20). I had to sand down the rings a little to get the baffle to fit in the body tube.

I look forward to flying it soon.

Glad to know that an EB-20 can be made to fit these. Need to retrofit my Majestic, or if not that put one in an Ascender when I get that one.

Have you flown a Majestic yet? I'm wondering why E15-6 is recommended but E15-8 is not. The Majestic is very light, and I'm surprised the extra two seconds of delay make such a difference. Then again, I haven't flown an E15 or F15 yet.

I hope you have better luck with your first flight with your Estes Majestic than I did today. Yesterday, I also assembled mine with the recommended CA and 30 minute epoxy used sparingly following all the assembly instructions. I used the recommended first flight engine, F15-6 and the PSII wadding, starter and plug.

I flew in calm conditions with rod close to vertical. The smile in the picture was short lived. Shortly after it came off the rod it went unstable and cartwheeled through the air for a pretty good distance landing between my vehicle and the vehicle parked next to me and was damaged when it thumped on the ground and ejected it chute near the spectators standing nearby.

I'll be contacting Estes soon to request a different PSII kit. I'm really not comfortable repairing mine and flying it again.

Perhaps yours will fly better since you have the added weight up front with the Semroc baffle on yours. I ran it through OpenRocket last night and it didn't show stable without added nose weight but I ignored that thinking it was a data entry problem on my end and it should be stable since I assembled the Majestic per the instructions without any modifications.

Can you please post your Open Rocket File for this model. I did a RockSim on it and it showed it to be plenty stable even with a heavy G80 motor in it.

My Majestic has two flights on it - both F15-6s and both quite nice. My fins are on backward but the difference is very slight. It's otherwise dead stock.

Both flights were nice and straight with a gorgeous long, straight boost. It carried an Estes Altimeter on the second flight (which would've helped stability) but didn't on the first.

My notes say the ejection was a touch late on the first flight so I'd think an 8 second delay would be too much.

Oh - before you ask: 1307 feet.

Second afterthought: for what it's worth it was flown from a six foot long 1/4 inch rod.

You will need to 'notch' the baffle rings in order to get it to slide past the shock cord mount.

Sorry to hear about your Majestic 'flight', Steve.

I'll be flying mine next Sunday. I will post pictures.

BTW, nice hat.

My Ascender flew one flight with the F15-6 just before I flew the Majestic and I couldn't agree more, quite nice! I flew four of the F15-6 engines with 6 and 8 second delay, and one with zero delay yesterday. These new engines are great. The Ascender / F15-6 combo is just perfect and rocket was recovered just a short distance from the pad since we had minimal winds.

Thanks, you always post your altimeter flight data (and you knew I would ask).

It's become my standard launch hat. I forgot to stick my NAR and Tripoli pins in it before I left the house though.

I have several hats I could reach for on launch day but I always seem to grab the EnerJet hat!

Also good to know about the EB-20. I figured that was the one you used from one of your other posts. I need to pick up a few from Semroc.
