The HW has a 6 litre header tank on the back if the firewall which supplies the main fuel pumps. The two feed pumps are located between the fuel selector and the header tank and their purpose is to keep the header tank full. Without a feed pump running, no fuel will be pumped into the header tank a...

I'm not familiar with the HW, what is the "feed pump"? Is this another pump that's different from the Rotax fuel pumps on the firewall? Because those are powered by the engine directly.

There's been a fair amount of discussion of this either here or in the sling builders facebook group. The conclusion, as I recall, was that the intent is that by sandwiching them between the parts any pullout force is transferred through the rivnut face onto the spar. If the hole went through everyt...

No, but I've tried using Duralac for this purpose on the tail, I think it's a similar product. I've also been dipping rivets in it. Unlike corrosion X, which is an oil-like substance, it cures to a slightly flexible layer, so you have to apply it and then promptly assemble. It gets pretty messy, esp...

I had the same issue on my rudder, most of the dimpled holes so far have not needed any further drilling so of course eventually I forgot to check and ended up wondering why the rivets wouldn't go in on some holes. On the VS skin I did notice that if I didn't debur the holes before dimpling, the riv...

It sounds like you have plenty of space but one thing to consider is that the fuselage can't easily be put away once you've started it. I'm going to build the wings first and then hang them from my ceiling. Once the fuselage comes together there will not be room for the wings where I'm building.

I'm only done with the empennage and I can't tell you how long it took in hours but it took muuuch longer in calendar time than I expected. Not because it's a lot of work, but because of all the questions, missing tools, do-overs, and then just life getting in the way. If you know exactly what to do...

Technical said it should go under? That seems really weird. I'm about to rivet my elevator tip skin and the instructions say "cleco [tip skin] on part 21 and the skins as illustrated" (my emphasis). Not only does it make sense aerodynamically that it go on top, if you put it under it seems...

I have a few more: Paint scheme - will affect upholstery colors and interior paint. DIY wiring or purchase built harness - I don't know what the lead time for places like Midwest Panelbuilders are but they seem pretty busy so if going with a pre-built harness, an order needs to be put in sufficientl...

Sling and Aviation101 recently posted videos of flying to Canada. I thought you needed 12” tall number for flying internationally. Is that not true for Canada or is it just not enforced. I think you need 12" numbers if you're transiting an ADIZ, but apparently there is none at the Canadian bor...
