Fuel Tank Pressure Test

-



Today we used this ingenious gadget to pressure test the fuel tanks. You simply block all the ports to the fuel tank and pressurize the tank to 1 psi and wait. You then apply soapy water to all the seams. If you don't see any bubbles, and the the tank holds pressure for an hour or so, it passes.


We immediately founds a small leak, but it turned out to be a bad seal in the pressure tester. After that was fixed both tanks passed the test, and are ready to be installed on the wings.

Customizations

Before we started our build we selected  several custom options for our plane. Strangely enough, there is no list of all possible options. We just had to keep asking to find out (HINT: someone at TAF should make a list). Anyway here are a few options we selected as part of our order:  Split Rear Seat - This will allow for three passengers and luggage. We also plan to make the rear seat removable because we most often fly without any passengers and lots of luggage. Extra Long Seat Rails - My family is really tall, so we asked for extra long seat rails. This will allow them to move the seat back a few extra inches to accommodate for those long legs. Foot Pedals - The standard it comes with really cheap looking rudder bars. It turns out there is a option to get custom aluminum Sling branded pedals. They are on backorder. Besides the options from the factory, now that we are building we have learned about many small modifications that other builders are making. Here are some that we are

IPad panel mount

A few weeks ago I got the new Apple iPad mini. The smaller form-factor is perfect for the Sling TSi. However, I don’t want it to be floating around on my knee, so I have been looking for a good way to mount it somewhere so that it is hands-free and does not obstruct the view or the instruments. I think I have found a good solution.  I  got a tablet mount on Amazon (link   here ) with a short adjustable arm and   attached the mounting point to the left of the panel (see below). The panel is made of aluminum, covered in leather. I used self tapping screws with plastic washers, but you could use rivnuts. Here it is with the arm attached.   I don’t like the tablet holder that came with it (too bulky), so instead I used another mounting point (Amazon link here ), and some Velcro to attach the arm to back of my iPad cover. That works great, it does not come off easily, it is height adjustable, and it does not take up much space. I also added a small metal tab to hold back the front cover, so

Floor under Back Seat

For some strange reason, there is no floor under the back seat. I guess Sling expects the back seat to cover any cold air leaks and stop stuff from falling into the space below. This seems really sub-optimal, dangerous, and needs to be addressed. Without a floor, the seat belt buckles can be pushed through the seat and fall into the space below which houses many important linkages that are needed to fly the plane, so that could be bad. Also there is a huge amount of cold air leaking into the cabin from underneath the seat. To fix this I decided to add aluminum floor panels under the rear seats, to close up the space. They are mounted with rivnuts, covered in carpet, and easily removed for inspection. The final result shown in the first picture.  It is an easy build; you need a rivnut tool, metal scissors , rubber mallet, and a few others. Measuring, fitting, and installing requires various advanced yoga poses, but it is doable. First I made a cardboard template for the two panels, meas
