Surprisingly, recent research has shown that the blunt training edge creates less drag than the traditional sharp edge. Larry Severson Fountain Valley, CA 92708 (714) 968-9852 larry2@...

Thanks Sam.

Here is Bob Nucholl's dissertation. Getting the wires in while keeping the flames out http://www.aeroelectric.com/articles/Firewall_Penetration/firewall.html Many of Bob's on-line articles are

My plans are in the hangar, so I can't be certain, but I believe you fill in the end gap with flox. You are correct, the end of the elevator should be squared off - that's the nature of that airfoil.

Larry, Thanks for your reply. I was unable to view the picture; I think the Q-list does not allow pics. Would the stiffener be horizontal or vertical; 1/4"x 1 or 2" plywood; 2,3,4 layers

Kevin, Hold off for a day or 2. I have sent an e-mail to Justin Mace about his electric through bulk head. It just might be what you are looking for and you won't have to build anything. It may be

Kevin, What I am doing is using stainless towel bars, They are various sizes 1/2" througn 1" tubes with about a 2 to 3" flange. I can slip the wire through the tubes and fill it with fire caulking

Sam and Ron, Ron, In my engineering days I have done a bunch of power stuff, I don't see a problem in that area. Sam, thanks for the info. The book is already on order. To the both of you,

Builders of LS1 canards, I have a question... The template is confusing in that it is unclear how you achieve the glass to glass trailing edge bond. Where the ailerons and rudder have a "joggle"

Keven, In my minds eyes I don't see a problem with the hole, but what fire rating is the phenolic? also by making plug-ins you are adding more resistance to the electric system. I would check alot

Kevin, there is no good reason to do this. Use a small opening and pass the wires through it. Only cut holes in the firewall as a last result. Have you purchased the AeroElectric

Oops... Kevin

Guys, In my minds eye I have designed a pass thru terminal block for wiring that comes thru the firewall. This pass thru will allow me to easily disconnect wiring before removing the engine and

Thanks all for the input. Looks like it shouldn't cost as ;much as I had expected. Been pretty busy recently and naturally this group has been quite active. May take a few more days to get caught

Kevin, There are standard bulkhead fittings , tubular shape with compression flange. They come in various sizes, used by electricians . I used one of these and bundled the wiring through it. The plug

Joseph You will not need the plans built firewall stiffeners as you are taking your engine mount loads into the firewall and fuselage differently using the Corvair. If you reference the photo I

I doubt the Q would fall on its side. The engine does not move that much as I could only swing mine out about 45 degrees. I was enough to get at all the accessories and I highly recommend it. Larry

Hi Sam, That's awesome! This give me an idea...... :-)
