On Friday, December 12, the FAA certified N746 SC, which I am almost sure is the first Javron kit to fly. This cub has an 0-320 E2D with a Catto prop. Here are 3 short videos that I took. http://youtu.be/dG4TkJdGGNMhttp://youtu.be/iqMNqQKMo90http://youtu.be/mHePJSvPtxo

Well done! We want some close ups and details, I've been waiting to hear about this one.
Evans Plunge is still here. Not a bad place to go if you have kids.
Larry took a lot of pictures while he was building, and scrutinized virtually every part to try to make his Cub light. I'll see if I can get some pictures with details.

Here is a partial list of things up front to keep N746SC as light as possible.
MSD ignition wire and Denso 14mm spark plugs
Carbon fiber plenums instead of standard baffling
1.5 inch exhaust system into 1.75 inch mufflers
Aluminum intake tubes on engine
Vans filtered air box which gives filtered air with carb heat.
6.5 lb starter and small starter ring gear
B &C 8.5 amp alternator
Titanium firewall
Aluminum oil cooler
Matco wheels and brakes tubeless tires. These will be replaced with the Desser 22 inch pillow soft tires.
This just a partial list that is pictured here. I sent Jay at Javron a more complete list. The empty weight came out right at 10 lbs. + under 900 lbs.

This is a really slick airplane. When he posts some of the construction photo's it'll give more insight into what can be done.
Congratulations, Larry!

Here are some photos that I had.....
A little background on Jay DeRosier and his company, Javron. For those who might not be up to speed.....
(edited from a previous post)
Jay owns a machine shop. That is really his primary business but he is an airplane nut (like so many of us on this site) and several years ago he was at Oshkosh thinking it might be fun to pick up a little extra work. Well, he met Nick Smith, they hit it off, and a few weeks later Jay was welding up PA-12 kits for Nick Smith. When Turbine Cubs (now Backcountry Cubs) bought out Nick they contracted for Jay to continue welding up fuselages including the PA-18 model. Jay welded about 60 kits together and the feedback in this period was exceptionally positive. Backcountry decided to pull everything into one location and so they no longer needed Jays services.
After Backcountry discontinued subcontracting to Javron, Jay thought it would be fun to get back in the business so he built all new jigs (as opposed to using Nick Smiths) as close to the original Piper drawings as possible. Jay is a machinest by trade so he works in thousandths of an inch. His jigs are all super-accurate and to Piper specs. So any part you buy from Atlee, Stoddards, Univair etc. will fit with Javron stuff. Jay is trying really hard to get back as close as possible to the Piper specs. Nick beafed up a lot of stuff. Jay is going back to the original as much as possible.
So...... you can purchase a kit from Javron which is comparable in parts count to Backcountry but it will be closer to a Stock Supercub than say Backcountry. The Backcountry Cub and SQ2 kits are pretty highly modified Cubs with a specific mission goal. Javron will have some mods but it will be closer to stock.
Javron will also sell parts, partial kits, and pretty much anything you want. So if you want a tacked fuselage (Ala Spraker) he will sell it that way. You build what you want but if you decide you don't feel like welding the seat, for example, you can just buy one from Javron. Mix and match all you want and it should fit as long as you are building from the plans/Northland CD.
Jay is VERY flexible and will build whatever you want.

Larry has built an exceptionally light Cub and done a fine job. It will be nice to see it in person.

tempdoug, This shroud is overkill and duplication. The top cowl will do the same thing on it's own.
True, but it looks very nice and clean without all those klutzy baffles and springs and stuff.
Larry/Clint,
Great looking and I'll bet great flying bird!!

Nice sound to it. Who made your exhaust.
I have to say I really like the looks of that plenum. While I understand that they arent really necessary, it cleans the "look" up so much that I'm starting to lean in that direction. Do away with 200 screws and rivets and 40 feet of rubber baffle material...
