Engine compartment pictures of a Van's built RV-12iS

I was in Sebring FL this week attending some Rotax maintenance courses at Lockwood. On Friday I was lucky enough to catch their RV-12iS during an oil change. I grabbed a bunch of photos and put them in a google photos album:

There were a couple of things I thought worth noting: there's a piece of tubing attached to the throttle cable a few inches prior to where it attaches to the throttle body. I know of at least one person who has detected a location where their throttle cable was rubbing its way through the powder coating on their plane. I also noticed some RVT on the pitot tubing just aft of the plastic block the rigid portions passed through right behind the propeller hub.

I've also attached a photo of the beautiful layout of the wiring around the fuse box. Mine isn't nearly as pretty as this one!

Thanks for posting these. I'm in the process of routing hoses right now. It's nice seeing an example of how someone else has done this.

My throttle cable was routed -under- the engine mount support tube.. instead of -over- it. After about 300 hours, I noticed it touching, along with what looked like brown rust around the area. I threw a plastic tube on the cable -- just like Lockwood's plane.

Finally this week, I re-route the cable the proper way.. there is still potential for rubbing, so I left the tube on. Here is the damage it did. Its mostly powder coating that wore away.. but it did start to eat into the metal. I'm going to continue to monitor that area, but I don't expect anything to develop.

The pictures of this firewall forward installation are of an S-LSA RV-12iS built by Van's Aircraft Assembly Division. This is an example of the high quality work done by the Van's AAD team everyday at the Aurora, OR facility.

Most impressive thing I notice is how much more slack they have in some of their wiring and probes than what I was afforded.

This is super helpful and timely for us at HP Aircraft since we have been approached for a possible aircraft design using a Rotax.

The engine mount is quite unusual, at least for us in the Lycoming world. It is not clear from the photos how the nose gear strut attaches to the mount and/or firewall. Could someone post a picture that shows how that works?
Also would be super helpful if someone could post a picture of the engine mount hung on the firewall with nothing else attached.

I'm curious what the structure is like behind the firewall in the RV-12 to carry the engine mount loads out to the fuselage longerons.

I'm also curious about what looks like a gas cylinder attachment brackets in front of the battery. I'm guessing that that has something to do with the induction system, since there is no duct attached to the throttle body. Is the mount for a filter canister or something like that?

That is interesting Bob, because the production SLSA airplanes are built with the exact same parts that ship in the ELSA kits…..

That is the mount for the oil tank.
Likely removed for cleaning during a 100 hr inspection.

Ah, thanks. I see the oil lines now too.
