All parts get a wash first thing to remove some of the fiberglass dust. Slight sanding of edges needed on Centering Rings to fit MMT and Booster section.

I did not. It came with Wildman's new tubing also.

I'll be curious to know the weight difference in the tubing - have you weighed anything yet?

Yes, I put weights on the first post. The molded nosecone weights 22.2 oz. Not sure how much the PML fiberglass nosecones weigh.

Weight difference really isn't much. My old stuff is 25.2 oz./foot, your new stuff is 21.2 oz./ft. No big gain there.

I'm using wood for the aft CR along with tee nuts to secure the trust ring. CR in picture is only tacked on with CA. Will go back and epoxy later. Thrust ring can be unscrewed and used on another project along with Aero Pack if desired.

How long are the tubes? That payload bay looks pretty short, especially comparing it to the coupler and shoulder lengths.
Edit: read the first post. Could be deceiving in the photo, but the payload looks shorter than half of the 60" booster.

Yes, that's just the angle the photo was taken. Booster is 60" long and payload is 30". Coupler (E-Bay) is 18" with a 6" switch band.

I wonder why the payload section is so much shorter than the Darkstar? It's is 48", guess I just assumed they would be the same.

The website show the Ultimate Wildman and Darkstar the same size (60" booster and 30" payload). Maybe Tim gave you a longer payload.

Heh, I never even looked to see what the DS was supposed to be. Guess I got a bonus!

Wasn't totally happy with placement of aft CR so I reset it. Glad it was only tacked. It's now epoxied into place. Also epoxied tee nuts. Top two CR notched for Kevlar bridal which will be attached next.

My Darkstar has a 60" booster and 48" payload. Bought a year ago with the heavier fiberglass tubing.

I've noticed that with some older Ultimate kits. I think Tim must have changed it because now the payload section is only 30".

Had a chance to work on an OpenRocket file today. It's not complete but close.

Seeing several Cheese-a-roni motors (H all the way through M impulse) blow last year has got me steering clear of them whenever possible...
Jeff - good looking build! My only comment so far is to check and see if your payload section will be long enough to fit your main chute. Wildman seems to enjoy short payload sections. (Edit: I just realized you have a 6" airframe, so nevermind!)
If you end up flying a smokey motor just make sure you won't have the clean the pad afterwards.

My thoughts exactly. My Skyangle XXL, inside of an XL free bag (not XXL, so it's snug) fits pretty easily in my Hawk Mountain Proteus payload bay, and that's a 48" tube. My guess is that he will be fine, but it may be tight. Recess that nosecone bulkhead into the shoulder to make room!

I don't have the chute yet. When I do I'll check if I have enough space. Not sure why the payload was shortened, good thing I don't have an inferiority complex.

I plan on recessing the nosecone bulkhead (which I'm making removable) about 2". I want enough room yet for the nosecone shear pins to be just above the bulkhead.

Motor mount tube is completed and ready to be installed into booster.

I've never used a deployment bag either. Too many variables IMO...

The picture below is from SC Precision's website. The red is the thrust plate, orange is the aft centering ring, and green is the booster body tube. What a thrust ring does is transfer all the motor thrust load to the body tube rather than through the motor mount tube and centering rings.

I always assumed that with the TTW fin attachment to the MMT and BT, that kind of direct transfer wasn't needed. If you thrust against the MMT, the fin attachment transferred thrust to the BT. To me, that didn't seem to be a weak point that need to be by-passed. Am I missing something?
