Okay, I figured I’d take a break from scratch building and build the Interceptor E I bought a while back,
I also got the John Pursley Union Skin (not because I have any particular affectation for the Civil War but because I liked the dark blue color.)
Instructions have lots of warning about exceeding 425 grams.
I am going with mini rail buttons and I have a 6 foot 10x10 rail.
I fly in a medium size field (parking lot essentially with soccer fields on all side). This rocket likely will be flown once, maybe twice, I would like to get it back relatively undamaged.
I’d prefer to stick with the 24 mm motor mount,
Only recommended engine is E9-4.
Seems like Estes website doesn’t even LIST this motor
https://estesrockets.com/product-category/engines/large-engines/
All they have in 24mm is E9-8, or the E12-4,6,8
I am thinking the E12 would be good, was thinking 4 second delay?
So do I need to worry about the weight of the skins much? @neil_w , I think you built a Ragnirak with these, so your input as usual would be appreciated.
Are the Wing Support and Fin Support pieces really needed?
Will it screw up the skins if DON’T put in supports?
For the mini rail buttons, will just screwing them into the body tube be enough? I have the crazy idea of building and finishing the rocket, putting masking tape over the button sites, drilling a small hole in each through the tape, injecting some Gorilla Polyurethane Glue in the holes, covering the holes and allowing to dry hole side down for a couple days (figure that curing might take a bit as no air circulation.). Thought that might give me some thickness or substance to hold the mini button screws in place. ????
