For those that have use a NACA vent to provide an air inlet for the overhead console, would you recommend installing them at this stage. My assumption is that it would be much easy cutting the holes prior to riveting the tailcone together. My second question is has there been consensus on the best local to place the vents yet? I'm also just starting to start looking at NACA sources. Van's has one for $6.25 and ACS has several, but all are over $30. I was caught off guard by the price differences.

We placed ours just behind the baggage bulkhead. Again no science, just the shortest distance and it's the same place one of the very first OH console installers placed his with good results. We waited till late in the build to add the vents but well before the canopy was attached. Wait... The canopy still isn't attached. Darn. If you want to see some detail of our OH console visit: http://www.painttheweb.com/rv-10/console.htm Good Luck, Robin ________________________________ Message 8 _____________________________________ Time: 03:02:07 PM PST US From: John Gonzalez Subject: RV10-List: Van's cowl vs James cowl I am wondering whether a few builders can comment on the results that they have had with the James' cowl. What I am looking at is the overall quality of the James product vs Van's c owl or compared to other Van's fiberglass products. I am not so interested in the speed improvement debate, but quality and whe ther by using James made more work for the builder because Van's made the F W package for the Van's cowl. Also, I believe if I have energy left at the end of my build that I will be doing a plenum for the engine and I might be interested in molding it for others and the James has those nice intake rings. A nice plenum made of 50/50 carbon/kevlar with high temp resin would look c ool and I could realistically do that...energy remaining. What did van's credit for not taking the cowl with the finishing kit?

I am pretty sure it was right at $800 for the cowl and spinner parts. The tough sell is the spinner kit. If you are going with the hartzell the larger spinner kit is more than the James Cowl itself. I haven't heard any reports about improved speed, cooling, or what have you. Come to think of it I haven't heard any reports about the James Cowl at all! -Ben _____ From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of John Gonzalez Sent: Thursday, December 13, 2007 3:01 PM Subject: RV10-List: Van's cowl vs James cowl I am wondering whether a few builders can comment on the results that they have had with the James' cowl.

To me cost is secondary. My wife requires a ton of blowing air in her face when she flies. If installing an overhead vent is what it takes, then that's a mod that will be done regardless of price. I almost had to install air conditioning, but she has since relented on that requirement. There two methods.

You want something low to the ground while you work on it, unless you plan to skip to the gear install first. You're going to be climbing in and out a whole lot and leaning over a bunch before it's up on gear. How tall are you???! I used two pallets fastened together with casters on the bottom, and it was still a little tall. I put a carpet scrap between the pallets and the fuse. BTW, If you plan to skip to the gear install, make sure you've done any soundproofing to the subfloor and floor pans under the gear leg brackets. I and others had to remove them to get the subfloor work done, which in itself involves a lot of bending and leaning, so you want a short stand anyway.
