Seriously???are the centering rings plywood?
I believe the previous version also had ply rings.I am happy that Estes has finally decided to start using some plywood rings with some of their larger rockets!0
All the PSII builders kits had plywood rings. I dont know about the PSII kits like the Ascender that were basically big E2X kits.I believe the previous version also had ply rings.

The "So Long" is minimum diameter, so has no centering rings. Balsa surface mount fins, FWIW.It does, here is an original in a bag. All the non-E2X PSIIs back then used plywood rings, except the Star Orbiter.
The E2X PSII used Plastic Rings and they take H power in my tests with the Ascender.
Anyone know what the new SO-Long uses?

I know that the old kit had them, so did the other old PSII kits, or at least plastic ones, like the trajector. But lately Estes has been using cardstock ones in a lot of their PSII rockets (Black Brant, Der Big Red Max, Doorknob, etc.). I am glad they brought this one back with centering rings that will stand up to big motors.They used plastic rings like this on the motor mount that the fins locked into, good for H flights so far in my tests at Jean dry lake 8 years ago. Their elastic shock cord was to mount in a plastic hood on the side of the body tube by the nose. That would rip out.
Here is what I did to them to make them last for recovery that is replaceable

I used Plastic Weld on the edges. No issues after a couple dozen flights, even on G motors.
One of our club members glassed his original PS II version, and used a 38mm mount (I think). The space in the nose cone was set up for a tracker. The rail buttons area good idea, just remember to use spacers to clear the edge of the nose cone. And don't forget to balance properly. Since the CP won't change, the CG has to be tested for the weight of the motors you want to use. Also, Dragon Rocketry has a nice 4 inch diameter carbboard version set up for 38mm.I too got my kit over the weekend. After checking it out, I immediately realized this needs to fly on high power motors.
Possible mods include glassing the tube and adding rail buttons. Anyone else considering this? I’ll never fly it on BP motors.
Yes on buttons. Be sure to stack them to clear the nosecone shoulder. No glass really needed. I fly my 1st run kit on F-G motors all the time and.I too got my kit over the weekend. After checking it out, I immediately realized this needs to fly on high power motors.

I have had a similar experience.I originally installed the launch lugs that came with my BRM. I got a lot of rod whip, and, on the advice of my LSO, I added rail guides. I have never looked back. Some fields still ask me to launch from the rod and after I ask them if they really want me launching the BRM on a G80 from the rods, they usually (all but one time) assign me to a rail.

I've flown mine on G-H motors, all composite. No glassing, tape over the fin leading edges, nose cone modified to allow weighting for larger motors.
Oh, and I 3D printed rail guides that look more like the scale lugs.
I have had a similar experience.
Have had no issues. Upgraded the shock cord with a Kevlar mount to the top of the tube, 6' of 550 Paracord for the rest.Yes on buttons. Be sure to stack them to clear the nosecone shoulder. No glass really needed. I fly my 1st run kit on F-G motors all the time and.
Now that I know that BP motors are recommended, I may shoot one off on an E16 or F15 at the next mid power launch.
We'll see.
