Killer "Rocket Fuel" bladder tubes

I am working on a new style bladder tube with graphics that is SUPER quick to build. Look for a tutorial after the first of the year.

Leading Edge Graphix

As a spectator goes there only a few things that set the planes apart from each other, they are going to see obvious geometry differences and any tape and tail covering colors from plane to plane but that is about it. When I was looking to start building my own planes one of the aspects that was very intriguing was to find a way to set them apart in a way that the general public could see. After some various ideas like painting the wood, stenciling the covering, creative taping, and a few others that aren’t worth mentioning I found a way to print right on the LE paper itself. The printed graphics offer some really neat advantages. First and foremost great looks, with the help of a graphics program the sky is the limit, colors, text, and artwork can all be printed right to the paper. Secondly the weight added for this artwork is almost zero which is a really big deal considering that it is going to get wrapped around the LE.

First create a basic layout of the paper. You can see the basic layout of the muffler area, “back” of the LE where each rib will go, top, and bottom. (My seam is on the bottom just behind the LE spar not on the “back” where the ribs are like most models)

Work up some graphics in the areas that you want using the reference lines to make sure everything fits. I like to split the screen so I can see the inboard and outboard graphics in the same window to make sure they look good together. You can see in the screen shot the active view is the outboard and under it is the inboard. This takes quite a bit of time even if you actually know what you want it to look like before you start. I am learning the software and developing the design all at the same time. As I learn new technics and get new ideas the designs evolve. Actually I can’t remember if I have done 2 sets of planes the same since I started.

Then turn off the layer with the layout lines leaving just some reference marks so you know where to cut the paper.

A couple of things to keep in mind and they will all be printer specific: you have to be able to tell the printer that you want to print on a custom paper size (in my case I use 23x8.5), the paper I use will not feed properly on its own and must be glued (dust 3M77 on a reg piece of printer paper) or taped (huge pain) to the LE paper, the ink is water soluble ( I used water and white glue for gluing it to the foam).

With some experimenting and effort you can create a unique LE. Here are a few that I have come up with.

It is hard to see in the photo but the base color has a fake wood grain, neat effect.

This is some of the new top secret stuff I have been working on this winter, do you see the bladder tube?

Check out the new Allen DeVeusky model

Allen is currently testing a new Eles1 Models prototype F2D wing. Allen feels the Cyrillic lettering helps in certian conditions. Only more testing will tell.

2011 test plane RTF

So the question has been asked many times- where should the lead-outs and bell crank be? I have asked different people from time to time and received all sorts of theories. With due respect to those I have talked to, the answers tend to sound more like folk lore than anything else. Generally a 2nd or 3rd variation of an answer given in the 50s-60s in an article about something other than combat.

Here are a few things I know for sure:
1. The drag on the lines goes up when the speed goes up/down when the speed goes down.
2. In maneuvers the speed goes down, sometimes a lot (40mph - yes you maybe going 105 in the flats but not in the turns!)
3. There used to be a formula on the www to calculate the LO position. I am sure it was based on an article published in the 50s-60s.
4. I really want to know where these should be for one simple reason- I can build my planes how ever I want and I want the BC and LO in the best possible position.

So I built a plane with an adjustable BC. In the forwards most position the BC axle is touching the back edge of the spar which puts it right on the CG of this plane, and then it can go back up to 3.75" aft. The LO positions are every 3/8" from the back edge of the spar back 3 inches.

With the externally mounted BC this is also an opportunity to try different LO line spacing and push rod throws on the BC.

Let us know what your ideas and predictions are in the comment section below.

2 builders with finished planes now!!

Here is a shot of David Owens holding Kevin Herbstreit's first complete SS. Looks like they were inspired by the holiday spirit while they were covering it!!

Reports coming in from builders

Howard Williams and Kevin Herbstreit are cranking out Streamer Shuttles of their own as we speak.

Howard was the first one to complete a SS and get it in the air. Here is a quote from his email "The heavy SS flies fantastic.  The larger bellcrank makes it easier to trim, in fact, no trimming was necessary.  A slight warp to remove and that’s it – Perfect!" Howard has reported a second SS is RTF this weekend at an amazing 229g! That is the lightest SS ever! I cant wait to hear his report on that one.

Kevin is covering the first of his SSs tonight with hopes that he will be up and ready to fly early Saturday. Kevin has David Owens at his house helping with the project so I am confident they will have it ready to go.

Bell Cranks

I flew the new bellcranks over the weekend and they work like a charm. I really didn't expect that they wouldn't but you never now sometimes. They are .070 thick which really makes a nice fit in the pre-cut slot in the center section of the kit. The bellcranks only have pilot holes in them so you can drill them out for whatever size axle, pushrod, and lead outs you are running.

The first order is all gone, so I will take requests for pre-orders for the next batch. I have to order a couple hundred so don't be shy. They are $2.00ea plus actual P+H to your address.

The Hunt for Domestic Covering

This seems to be one of the most challenging areas of the building process, finding a good source for covering in the US. I have looked high and low all over the net and have yet to find a source for the "right stuff" and here is what I have learned:

-The covering that works the way I want comes from Eastern Europe and is of course metric; .03mm or 30 microns thick. Domestic covering is sold as 1 mil or .001 (30 microns is .00118"). The problem with 1mil film here is that it is more than likely actually 92 gauge or .00092."

-The film is often referred to as "Mylar" which is like referring to cola as Coke. The film is a biaxially  oriented polyester film or PET film. There are thousands of PET films and other types that look just like them on the market and they are all different. If you add in that they can be treated/coated to have different properties finding the right one is a long shot.

- Being small fish we have to find a retailler that has the right film for sale that we can use. I have been told that the Euro covering is used as book covers, "Mylar" is widely used in the archival industry to preserve documents, art suppliers often list film, etc. I have yet to nail down the "right stuff" with this trial and error shopping. The challenges have been super high minimum orders, wrong sizes, and lack of detail about the film.

Do you know where we can get "the right stuff?" Post up some comments below.

Getting organized...

I am still working on the blog site to make it as useful to anyone building F2D planes... I added a page with the instructions so you don't have to hunt through the archive to find them.
