Title: links to videos or website dealing with the basic Flite Test building techniques
Post by: byrocat on July 02, 2020, 08:09:10 pm
I've acquired drawings for an EDF model that uses Dollar Tree Foam Board as the construction material, and am investigating how you cut the sheets to make the necessary folders and overlaps.

So, I'm asking for links that cover how to make the basic cuts for making folds as well as possible tools to use.

Downside of the original build article in RC Groups is that poster has lots of experience with DTFB and is using some advanced techniques, while I'm at the basic rookie level. OF course, yes, I do have FT kits in my basement, but they are already cut; so no real guide to know how much cutting is "enough" as opposed to "whoops, find another board and try again...."

Did some digging around on YouTube for Flite Test references and found one that talks about going from the plans to the DTFB cutouts. Reference in YouTube is "Flitetest Building for Noobs".

Now to see if there is anything on how to cut the single- and double-with slots for folding the cutouts and embedding tops and bottoms into fuselage sides.

Not going to start cutting DTFB until I've worked out how to do folding slots and such.

Finally found a tools for cutting the A/B slots in DTFB...?  https://youtu.be/rNtmTzbPxqI

Looks a lot like what I was looking for, rather than a simple block.

Some of the basics - cutting and folding plus glue guns. Looks like I'm going to have to buy a bigger glue gun to get the heat density up.

Apparently, the is (was) a matt cutter from Xacto that cund handle the two-blade slots as well as bevels.

Look for the video.  the Xacto device used to be at Michaels and Amazon Canada

Quick update on progress: have started cutting out the parts, Nose section top and bottom, elevator/stab, rudder and bulkhead basically cut out but waiting on the trimming tool for cutting the strips for folding the parts together.

Started on the main fuselage section today by cutting the straight lines. Thinking about how to cut the strips for folding the fuselage sides and top section versus the line in the plans drawing. Is this an A for B type arrangement based upon how FliteTest does their designs?

Good news is that I've ordered the EZ connectors (both mini and regular) from Great Hobbies plus got single-edge razor blades via Home Depot (or as one on my former co-workers calls it "Home Desperate") and have ordered one of the X-Acto foamboard cutter clone from off of eBay (being sent to work, whoopsie! didn't check the address before I pressed "order" so I'll have to figure out how to get into work to pick up my mail without having to spend two weeks in quarantine).

Off-topic but part of the order from Great Hobbies was one of the last of the FT X-29 FSW kits kicking around, something for this winter or maybe next year, which make six FT kits in the stacks, plus another six regular kits, plus three aircraft to be set up for flying.)

I received the printed ducted fan intake for the model from the designer yesterday, and learned a bit about 3D printing and how delicate the pieces are, especially as I would have to slide everything into place. I picked up the intake and gave a gentle squeeze to see how flexible it is. Actually quite fragile. Also, mea culpa -- my fault.

It cracked along the lines of how the section was printed about a quarter of an inch above the end.

Looks as if I'll have to flow some epoxy in and around the section that fits into the intake of the fan unit as probably run a layer of .75 ounce fibreglass cloth to stabilize this section.
