Default RE: Here's A Simple & FREE First Foam Build Plan! (Part 2)

Hi all and nice to hear from everybody. Here's hoping Saucer Guy or Fisher chime in sometime. Miss gabbing with them and hope all is well for them too.

Thanks for the search tips. Will try that.

(Editing this post to put the new link in for the plans....found it yesterday by way of clicking on his web page on the first page of this thread I think and then it's near the bottom of page links on his webpage....Let me see if I can dig it up directly to re-edit/post here in a sec...)

OK, got it...Here's his new location for his web page...


And here's the plans on that page...


The dimensions of the plane aren't critical. Many of us have changed things to suit our particular wants with say a 2nd or 3rd build as needed when severe wrecks caused us to build again. For instance, I shrink the length of the booms and also increased the size of the h-stab, elevator, and ailerons/elevons (whatever they are called....man forgot the name of them at the moment). Same deal with the v-stabs. If you look through this thread (good luck with that ) you'll find people listing their new dimensions they used.

I know I probably did with the last build of this plane that is current intact in my hanger and waiting for it's next chance at a flight. I found by shortening the booms and increasing the control surface areas a bit that this plane grabs air even better at super low speeds and will spin around and turn the other way on a dime. It's a unique little aspect to it, where you kind'a give a little nose up and hard left or right and it seems to turn right around like a kid kicking a skateboard around like that. Saved me more than a few times from taking a header into a tree or such.

Not that you need to change the original dimensions. It'll fly great and do all this stuff with stock sizes listed, but if you do use one aileron then for sure oversize it to help with rolling doing tricks I would say.

PS- Be sure to check out his build log of other planes. That guy really has built some incredible planes out of EPS, many of which are just renditions of this dual boomer but with a nice twist on the final design. I'm going to re-look those over here in a day or two to see what else he's come up with over the last few years, as well as refresh my memory on his prior designs. We all owe this guy a debt of gratitude, as he's made one rock solid design that has so many unique traits to it like no other plane IMO, and also is very durable even without the major strength mods I always do to my planes.

One thing that I got stuck on early on when learning scratch building was trying to pin down every little detail to the original plans to follow precisely. Truth is that you've got way more freedom in approaches to building these planes. Have fun at it and don't feel you have to do the steps as listed. Do what makes sense to you and don't worry about not following any kind of protocol. You'll figure out what works best for you after a build or two. I know I did, and was able to let my hair down, so to speak, after getting over that sort of thing.

Look forward to future pics and builds from everybody. Even if they aren't this particular design, all foamies welcome here, especially EPS stuff. Oh hey, by the way, a friend I showed how to hot wire is going nuts these days with EPP foam. He says he'll never go back to EPS. I prefer EPS for the less weight factor, but truth is if I had EPP laying around I'd probably start using that too on some builds where extreme durability without as many needed custom strength mods to EPS needed. Mainly for me sheeting the bottom or both left/right sides of the EPS fuse works wonders for strength, as well as a carbon tube arrow shaft (cheap at Walmart when on sale) to strengthen the wing. Some tyvek tape (found in the foam insulation isles at home improvement stores) works wonders for sticking well to foam and protecting leading edges and such.
