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 th...
I built my first RC when I was 13 years old. It looked great. It flew like a brick, from my hand (the launch pad) to the ground, in what now I would call a deadly spin. It took me several years until I went back to building models. Our first son was my assistant. One of the things I knew, was there was a need to “misalign” the engine in the longitudinal axis to compensate for turning tendencies. Then I earned my PPL certificate, and I could say I had a better understanding of adverse yaw, and left turning tendencies (no, I am not talking about politics). And that was when the lightbulb went off: sometimes, airplane designers, tweak engine mounts to offset the left turning tendencies. This weekend, we work in N333ST, our TSI. Arthur and I were in awe when we noticed how the offset looks like. You can easily see the engine mount itself (view from the top), and once the engine is mounted, it clearly points to the right.
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, ...
