1 hr. mostly contemplating my navel...

My progress slows when I'm not certain about things...  When it comes to the firewall, everybody seems to do things a bit differently - which means I have a hard time deciding which way to proceed.

Many builders seem to have either factory people nearby, the ability to visit the factory or have experts on hand...  I have none of these, so I thrash a bit...

Contemplating how to connect the diode to the starter solenoid.

Contemplating how to connect the diode to the master solenoid...  Which I have yet to decide where to locate.

The manual says to mount the starter solenoid with M5 rubber mounts, but those are not to be found in my parts packages.  So, I bought these, but I'm not sure they're suited.  Too high?  Probably should be double male, not male/female.  What did other people do?

Maybe the height is OK, but I still think I need double male (which were not readily found on Amazon at least).

My ANL 50A fuse on a holder.  I just ordered a waterproof (ish) ANL holder, which I think would be better.  Should come tomorrow, so we'll see if it's suited.

Finally got around to creating a new factory photo page showing pictures they've sent me focusing on the Sling 4 firewall.  Very useful!

It's here and on the Factory Photo menu pull-down above.

Enjoy!

Also, Mike (Mojogrip) has his full video review of the TSi:

2 hrs. on the firewall.  Thanks to Kerry for helping yet again!!!  Helps to have moral (and mental and physical) support sometimes....

Loosening that nut on the wheel of the servo enables you remove the cable so you can install the servo.  Note that the nut assembly has a small part inside, so be careful when removing it.

I had to trim 1/4" off the bushings to allow for enough threads to be available on the other side.

Starter solenoid location.

Sorry for the blurry photo...  Best place for the master?  The TCU location would be better...  Hmmm...  I'd consider putting the solenoids under the battery box, but that area I think will be busy with fuel lines and other cables.

Garage door open and fresh air in! 😁

2 hrs. on firewall forward.

I did find the fuel pumps, TCU, Turbo Servo and ambient pressure sensor (I kept calling it a temp sensor, but it's a pressure sensor).

Found the Turbo Servo (on left) and TCU (right) in a box with all the cabling coming out, which is all attached to the engine.

And the fuel pumps were in a smaller box inside the larger box.

The ambient pressure sensor was also in the box with the TCU and servo.

The engine 😁

Starting to put on the various parts...

This unmarked bag seems to be the package containing the hardware for the turbo servo attachment (though a few part numbers are different).

Looks like the servo can't be put on now because the cable attached to it doesn't seem like it can easily detach at either end.  True?  It does seem though like the bushing is longer than it's supposed to be as the nuts wouldn't have threads showing.  Looks longer than the manual photo for sure.

The ambient pressure sensor in place.

Bottom view of that.

Starting to get there!  The brake line is temporarily in place obviously as there's no grommet for the pass-through.

So many things getting in the way of working on the plane.... Work... work... work...

But, I should be able to get back to it on Saturday for sure.  Time to start installing parts on the firewall!

Meanwhile, you can enjoy this short Avweb video on the Sling guys non-stop flight from Torrance to FL!

I heard from two people (thanks!) that the Turbo Control Unit and Turbo Servo are attached to the engine in the crate, so I need to go look for those (I'm sure they're there).

That leaves the fuel pump and ambient temperature sensor as still needing to be located.

EDIT: If the temp sensor comes with the Garmin stuff, how is this different from the OAT?  Same thing?  I have that.

Also, I'd like to know where to get compatible fuel hose as I don't think I have sufficient length.

.5 scratching my head...

The engine crate had 4 boxes in it:

1. A large box containing the oil tank
2. A very small box containing just a few parts (e.g. regulator and some wiring)
3. A box containing an alternator and some related parts
4. A box containing engine oil

The factory tells me the following should be with the engine, but I don't see these:

• Fuel Pump - It seems I have some tubing in my FF kit, but not the pumps themselves
• Turbo Control Unit
• Turbo Servo

I've asked Jean at TAF USA.  Anybody else have a clue?

I'm also looking for the ambient temperature sensor, which the factory tells me should have come with the Garmin avionics...  I don't see that either...

The alternator box

The oil tank

The tubing for the fuel pump... But, no fuel pump.

So, the Rotax comes with the starter solenoid on the right, but I had, from Aircraft Spruce, the one on the left.  I'm guessing the "standard" one on the left is for bigger engines?

The one from Rotax fits in the space on the firewall as described in the build manual.

Anybody know what this is?

Close-up of it.

Did do something "useful" and drilled the mounting holes for the screws in this last carpeted piece.
