I built the Scion and Executioner where I had to cut fin slots. I have built about 6 or 7 scratch built kits where I had to cut fin slots. It's a lot easier when you have a template from the manufacturer. Having the customer cut the slots significantly reduces costs. Use a straight edge and sharp blade. I use a 6" metal ruler as a straight edge. If I can do it, 99% of you all can do it.Wait, so they required you to cut the fin slots...if true..that stinks!
I have the instructions for the Eradicator. It looks like an interesting kit to build. The Sirius website lists the skill level as Level 2. I would consider it a Level 3. Your posts will prove to be very helpful when the time comes to build the kit.Yes all 4 fins at the same time.
That's what I do. Just make sure the paper is well-glued to the ring. I like the resulting fit in the body tube to be a bit on the tight side, so the paper and glue joint will be under compression.Thanks for providing the URL for the thread. The thread deals with the lose fit of the CR's on the MMT tube. What about the lose fit of the CR's inside the body tubes? Would it make sense to glue paper around the CR's before gluing or epoxying the MMT assembly inside the body tube?
Since the kit is the Eradicator, I am working with 1/8" plywood fins.That's what I do. Just make sure the paper is well-glued to the ring. I like the resulting fit in the body tube to be a bit on the tight side, so the paper and glue joint will be under compression.
Oh, and this solution presumes thick centering rings. Would be tough to do with cardstock or even fiber rings. I almost always use 1/8" thick light ply rings where it works well.
I recall them being a little loose. I don't remember how much though.Hi bobbyg23, your Eradicator is looking real good. I forget if I asked if you had the same problem with your kit as I am. The centering rings fit loosely in the body tubes and the MMT tube fits loosely in the centering rings?
