I have a lot of mods I need to do to the bottom cowl.
I am removing the two scoops. Those have been replaced by NACA scoops on top.
There are also the exhaust tubes in the cowl that point straight back. The original plans/design call for exhaust that points straight down out of the cowl which were really draggy. The tube mood was an improvement but the in-cowl exhaust style is the lowest drag solution.

That said, there are two designs (by CustomAircraft.com in El Cajon) to choose from.
The Long-EZ version (33804-1):

and the Cozy IV version (33702-2):


Dave Adams brought up some good data assembled by Mike Melvill that made the Cozy IV exhaust design the #1 choice due to the position of the exhaust outlet. (Thanks Dave!)

So they are now on order and I can get back to modifying the cowl knowing that it will be one mod vs. a two-stage process.

So the scoops come off, the tubes come off and I may have to fabricate a blister for each exhaust pipe. This will be a good winter project.

Bill, I was looking over the issue with the Hydraulic Cylinder in the keel for the nose gear. I think your suggestion is right on the money.

I can cut the top off the keel aft of the stick and with the nose gear in the raised position, I should be able to get to it, no problem.

The access holes (as laid out in the plans) were never cut out, Once I get past this step, I can decide if I need to epoxy and glass it back together or install a series of anchor nuts so it can be removed in the future.

The keel is different in the standard/RG. It only runs from the forward canard bulkhead to the forward face of the front seat(s) bulkhead. It does not have the gull wing doors like current versions do. Instead it has a single (clam shell) door that terminate at the longeron. That along with the front seat bulkhead might explain what the keel didn't need to run the full length of the cabin.

Good to see you in Longmont last weekend. Spending a little time with 4 canard guys was definitely beneficial for me.

Good luck, Tom!

Well, it's easy for me to say "why don't you just cut a big hole there...", because its not my plane! Ha!

But seriously, that's what's nice about a composite plane, you can just cut a neat hole in foam/glass at an angle, then flox it back together. A few plies of BID for strength, a little micro and paint - Voila!
