I have had no problems in the last five years. I believe that the primary reason that Klaus wants a direct connection to the battery is to m inimize voltage drop considerations during starting. There were some insta nces of the starter pulling the voltage down at the buss to levels that cau sed problems with reliable lightspeed operation. Vince From: roger@smartdrive.com Subject: RV8-List: Lightspeed Ignition Module Completing the firewall forward on a RV-8A O-360 4 cyl. I have one mag and one Lightspeed Plasma III. I am locating the Ignition Module would like so me feedback on experiences from others. My concern is ignition noise in ra dios and interference with sensor wires. Mounting on the cold side of the firewall is difficult due to space unless I mount the module right behind t he panel causing potential interference. Has anyone experienced noise or sensor interference problems and what did you do to solve them? Has anyone mounted the module on the hot side of the firewall? How did you protect ag ainst heat and moisture? Any problems with a hot side installation? Also the instructions has the power go straight from the battery or battery side of the master relay to a =93pull-able=94 circuit breaker and allows t he unit to be turned on and off with a standard mag p-lead type connection. =93all Plasma II Plus and Plasma III CDI systems can be operated with a sta ndard aircraft key switch. A "P"-Lead (wired to the output connector) is p rovided and should be connected to the key switch in the same way as the ma gneto "P"-Lead. There is no current drain on your battery when power is su pplied via the input connector and the key switch is in the off position. A pull-able circuit breaker should still be installed in the positive power wire.=94 Even though it states there is no power draw you still have a unprotected w ire from the battery to the panel breaker that is hot 24/7 and unless you p ull the breaker=2C the wire is hot all the way to the module even when park ed. This just does not seem reasonable. I would like to know what others have done.

Dear Listers, Looking at the requirements for IFR certification of the RV-8, it looks like the only thing I don't have is an "alternate static source". This seems like it would be as simple as adding a "T" valve in the 1/4 neoprem static air tube that goes along under the left hand canopy rail. Does anyone have any suggestions on something I could just cut the tube and stick in line with a little thumb screw to switch between the fuselage or cabin source? I'm assuming this will meet the requirement? Thanks! PS - Attached are a couple of pictures from Taxi-testing and Magnetometer calibration this weekend. Cool?

I talked though the each of the things as I was checking them in an HD video I edited of the session. Thought some might find it interesting... http://www.youtube.com/MattsRV8?v=-byMWhyTwjA ..

What a great idea, Linn! Thanks. Here's what I did tonight including a couple of pictures... I added a small "T" Nylon fitting in the 1/4" tube for static air just in front of the instrument panel under the left cockpit rail. I cut a short piece of 1/4" tubing and filled it with black RTV and then put a piece of heat shrink tubing over it to form a handle. The whole thing fits nicely under the cockpit rail and from the pilot's position is just barely visible, yet can be accessed easy. In the event that icing conditions occur, the fitting can be unscrewed and the plug removed for cabin venting.
