    Advice Needed: Windscreen Hoop - Carbon Rod or Uni Cloth?

    …Or something else? Planning on a “low profile” windscreen hoop for the Rocket that will also provide some measure of rollover protection. Notional dimensions are a 1 inch wide X .500 thick composite hoop bow. Think of it as a sub scale landing gear hoop or crossbow arch. It will be laid up...

    Aviation Hoarding

    Like many of you, I collect aircraft stuff and hang onto it forever because I “…might need it someday”. Old radios, hardware, oil coolers, instruments…. Well, many of you are familiar with my Pacer project that was for sale for YEARS at fire sale prices and ultimately I donated it to charity...

    Reno. 14-18 Sept. Who's going?

    I am. Despite saying "this is the year" for more than a decade now, last time I was there was 1974. I'm flying the Rocket in on Thursday morning and leaving Monday. Anybody else?

    Smaller Pitot/Static Tubing?

    OK. We all know that 1/4 inch tube is the norm here but why? During the rebuild of the Rocket I asked this same question after running across some really slick 1/8 inch pneumatic tube and push lock fittings from MSCdirect.com. Its been flying for a few years now with zero issues. What...

    What Does Your Airport Do For the Community?

    With the increasing focus on the “evil” of leaded fuels and the occasional crash, comes media coverage of GA ops and airport closure discussions. Much of the time this coverage paints GA as nothing more than an exclusive “rich man’s” sport, and frankly, most of the arguments from our side found...

    Parts Wanted WTT - Garmin GNX-375

    In a bit of a jam here... Looking to add a 375 to my L-39 to get it ADSB compliant ASAP and apparently the lead time for this unit is 7 months. I found this out only AFTER I placed the order today. If anyone has this unit but is not planning to fly until July, I'm happy to keep my order on...

    Importance of Preflight... New One on Me!

    Flew the Rocket to breakfast this morning and after walking out from the resturaunt I notice a Raven standing on the cowl, apparently interested in the spinner. Curious, I thought - it must be interested in the polished aluminum. As I get closer, the Raven flies off and I go straight to the...

    Question for the Chute Riggers...

    First off, I'm not intending to put anyone on the spot for regulatory guidance here, just an opinion of what to expect: My L39 has cold seats, but the seatback chutes are in place and form the primary restraint interface to the jet. When we ferried the jet to SoCal a few years ago the chutes...

    Oil Cooler Equivalent Area - Rule Of Thumb Duct Losses?

    Ross probably knows this right off the bat... Given the typical aircraft header style oil cooler (Stewart - Warner, Airflow Products, etc) of a theoretical aperture area i.e 6x7 = 42 inches, how much area is lost to purely mechanical intrusion? Some of it is easy to calculate, like the...

    14/28 VDC Conversion - Basic Theory Question

    Ok, my electrical engineering accumen ends at basic ohms law, so please bear with me for some very basic questions. My L-39 is a 28 VDC system. I'm using two 12VDC AGM batteries in series to replace the insanely expensive 28 V Mil spec Concorde. The airplane is wired like a car in that the...

    High Intensity LED Strobes (ACL) - Whats Available?

    Background: Im already running LED position and landing lights, but my ACL system is still based on the familliar HID power supply and flash tube "strobes". The flash tubes are discrete units mounted outside the OML of the tip and I'd like to keep it that way. I have a bad power supply and one...

    Low Drag Cabin Air Exhaust - Whats Optimum?

    I know a certain record setting RV-4 builder/racer that found speed by sealing up the elevator pushrod at the aft fuselage bulkhead. It seems that cabin vent air was working to the back of the fuselage and exhausting at the rudder and elevator hinge line - creating measurable airframe drag...

    Ignition Timing Fun On a Dyno - Lycoming

    Some may know about my governor failure and major prop overspeed on my Rocket last year. Well, the mess is nearing resolution and a significant milestone was reached yesterday when the rebuilt engine ran across Ly-Con’s dyno. Since this engine has a fully programmable SDS EFI system, this...

    Do Free Image Hosting Sites Exist Anymore?

    With the loss of Tinypic, my ability to post pictures on various boards has disappeared. Im looking to upload, copy the link with the "IMG" code, then make my mark in any BB that allows it. I thought PhotoBucket was the functional replacement for Tinypic, but apparently the ability to share...
