Default Looking good

Hey Jereme.

That must feel awesome to have on gear and all ready to roll around

Keep it up!

Jereme, I saw some of these new front ends ready for shipment a week or so ago at Vans. I was sure I saw your name on one of them! I wasn't sure so I didn't let the cat out of the bag.

That thing looks sick!
Must be one of the first RV's with one installed.

Great times!

You bet! Although now I have to stand on a bucket to finish my wiring. lol A good leg workout never hurt anyone though.

Haha that's awesome Kent. I'm sure there are a few that beat me to it but I think Dreed is the only one I know of right now. I was really surprised how easily it went on. The weldments were all nicely done and the powder coat even seemed a bit better in the sense that it wasn't inside holes very much that prevented bolts from sliding nicely in. Now I just got to finish boxing up the old one to send back.

Default Wing Incidence

Hi Jereme,

It is good to see your project progressing, it must be very satisfying for you.

A comment - when you come to install your wings and set the angle of incidence you will need to ensure the top longerons are perfectly level both longitudinally and from side to side. That is the reason I left my fuselage in the build stand as I knew I had the right levels with no movement after I installed the wings. I only put the fuselage on its landing gear after I had set the angle of incidence and drilled all the holes required, plus removed the wings again to install all the anchor nuts.

With your project now on its landing gear the longerons will definitely not be level longitudinally. Plus when you install the wings the weight of the wings will deform the tyres further. Therefore you will need to compensate by adjusting how the fuselage is sitting to ensure the longerons are level in both axis as per the instructions.

Keep up the good building and I will look forward to future posts.

Cheers,

Thanks for the great comment Gordon. I did have it all leveled before it went on the gear (for other steps during the build) but with building in a one car garage and no way to put the wings on I figured I would just re-level it when I get it to the airport. Some day I will be able to build in a bigger space. haha

Looks great Jereme! Sounds like yours may have been a little easier than mine, but I am super happy to have made the switch. Nothing against the old design, but this seems much better.

I think the only reason I was slightly earlier was being so close to the mothership.

Cheers!

Jereme: For the firewall-mounted items other than the engine mount, are you mounting them on top of the fiberfrax-titanium sandwich, and if so,

1. Are you worried about the fasteners loosening up without a direct fit against the firewall metal?

2. Did you find you needed longer bolts to accomodate the extra space the fiberfrax takes up?

3. Any concerns about electrical grounds? Is your firewall ground directly against the firewall?

I was planning on only applying the fiberfrax to the areas of the firewall that don't have stuff on it.

1. Are you worried about the fasteners loosening up without a direct fit against the firewall metal?

No I'm not worried about it, the fibrax compresses quite well and is only 1/8" thick. The bolts are also torqued to their normal spec. I also put torque seal inside where I can inspect the bolts.

2. Did you find you needed longer bolts to accomodate the extra space the fiberfrax takes up?

Yes there were often times where I needed longer bolts but just barely. I probably would have been fine with the Van's specced bolts but I have found they sometimes spec on the small side with hardly any thread showing.

3. Any concerns about electrical grounds? Is your firewall ground directly against the firewall?

I am using a 48 tab forest of tabs ground block found here. This bolts through the firewall sandwich of stuff and connects it all as one ground. The titanium is also electrically grounded via the myriad of bolts and rivets holding it on too.

I was planning on only applying the fiberfrax to the areas of the firewall that don't have stuff on it.

I'm sure this would probably be enough surface area protection that you would get the protection benefit but then again I haven't tested it. DanH would be your guy to ask on that one.
All good questions Draker, check the red text above. Hope this helps.

After a bit of travel for work I am back to building. I have actually been doing things here and there but not much to show. I did however get a couple antennas installed.

You can see here the ADSB and XPNDR antennas installed in the aft fuselage. A little over two feet apart so they are good to go according to Dynon.

I also got the ELT mount installed on the left side of the fuselage. Don't let this fool you, it was a really PAIN to install this! Barely enough room to drill and rivet the bottom flange of this bad boy. I installed nutplates as accurately as I could for the ELT. Time will tell if it bolts right in. I wonder why Van's hasn't updated this mount for the ELT most people actually use these days...
