Looking great! I have started throwing paint onto mine. Masking will be fun, I think .
Does the third stage plastic transition for the new 1969 work with the 2157? Seems easier. And, what comparison between LES towers in both? Is the new one easier to build? I have an unbuilt 2157 I am getting ready to start.
Go with your plan for the fairings. They sat on top of the corrugations on the on the 1:1. Just use enough epoxy to keep them in place.These fin fairings are going to be the death of me. I have ruined 2 now with another set on order. Probably should have just bought a second complete kit for parts...
I tried following hcmbanjo's blog to fit the fairings but I am not skilled enough to get them sanded down evenly to fit within the corrugation. And if I squeeze them to fit, it buckles the bottom.
I am resigned to have the fairings sit on top of the corrugations.
My plan is to set the fairing exactly where I want it and then mark the location with a pencil. Then insert the fin with a few drops of CA on the root, get the fairing lined back up on the pencil marks and tack the fin root to the BT wrap.
From there I can take the fairing off, get the fin filleted with epoxy and then epoxy down the fairing.
I had thought about cutting back the corrugation to fit the fairings, but I have an even bigger problem if I mess that up.
I welcome your thoughts on this approach. Is there another way to approach this that I am not thinking about?
Does anyone know how much weight we need to add to the Saturn V's after converting to using Boyce's fin can? I cut my main tube down as directed to keep the lengh correct but trying to figure out the additional nose wight for the unit for the 24mm center.
Don't forget... the Boyce fin can has scale fins. Better double check the CP as well as the CG. Site says the fin can is 5 oz., might as well weigh yours. Add it as a mass item to the ORK file in this thread or do a mass override on the existing motor mount to account for it.Does anyone know how much weight we need to add to the Saturn V's after converting to using Boyce's fin can?

I cut a cowling, including the slot. I could then place the fin on the tube and hold it in place while the cowling located it. The cowling was then carefully lifted and the position of the aft end of the fin marked with a pencil on the airframe. The distance was checked and then copied to the other three locations, using a combination square.How did you measure and mark how far from the aft edge of the BT the fin was supposed to be placed?
Down under? Just a guess... or not... says Melbourne Australia!Winter is getting in the way of painting? Geez where do you live? It was 111* today here, I think 113* tomorrow or something like that.
Good catch... looks like there is an inverse notch on the opposite side as well.Mine is in decal and touch up paint stage.
I had a couple of fairing joints break when pulling off the masking tape so that will be fun fix. Using a mechanical pencil tip to push the masking tap in to the corrugation really helped!
Oddly post paint the upper section fits a lot tighter into the booster section.
Also looking at launch pics of Apollo 11 the top of the tunnel on the SIV-B stage is black and the area just to the right has a white cut out into the black stripe. Rockets of the World has the tunnel all white
