  1. Yamma-Fox added a post in a topic Help with Fuel lines, filter, gascolator please   

    Thanks Ed.  Yes my plastic header tank outlet is about 2 inches up from the bottom.  I Assume that there is NOT a bottom feeding pickup hose and weight in there.

    Thanks Jim.  That is where I was going, straight lines to header, remove firewall gascolator, fine filter just before carbs with the fuel pressure guage tapped in between fine filter and carbs (showing any flow problems through filter on the panel readout).
    Anyone disagree with this plan?
    Little out of my area of expertise on this one.
    Thanks!

    Help with Fuel lines, filter, gascolator please
    Ok.  Redoing all the fuel lines, vent lines, filters. 
    The prev owner was running fram G2 clear plastic filters on the run from the wing tank to the header tank.  At first look I liked that idea to keep an eye on any junk and keep the rest of the system downline clear.
    But at second thought I wondered if I were to get a big enough slug of water in the wing tanks, would that possibly quickly clog up those filters and cause a problem?  If so wouldn't it be better to let any water go into the header and sit in the bottom?  (where there is a large area for water collection below the pickup line)
    Is there a general consensus on using filters in the line between the wing and header tank?
    Question 2:  is a gascolator required?  I would like to bypass it and use clear filters instead.  It just seems redundant since the header tank drain point is the low point in the system, and I'll have filters in other locations.  I aslo do not like the drain point in the engine compartment.  I've had em seep in other planes and never liked the idea of fuel dripping that near the muffler!

    RX-1 IGNITION :
    Been waiting for the mount to come back from the welder, so I've been digging into other things on the plane.
    One is wiring ignition power to the ECU.  There is a single wire for that and I believe it is the only power source to the ecu, making it critical to keeping the engine running.
    I decided to power it from two sources, each switched and CB protected.  One source will come directly off of the engine magneto (alternator coil), prior to the main fuse for the charging system.  The other power source will come from hot battery direct. I will put a surge protector on the magneto side in case the engine's voltage regulator were to fail.
    I will also will diode protect each power source to prevent backfeed if I get down to one source (example that if the magneto were to fail I would want to switch the master off to conserve the battery, but would not want my panel being fed backwards through my ignition hot battery wire).
    So that is my plan.   Any electrical engineers out there (or just people smarter than me!) please speak up if you see me going wrong!

    Yep, those subarus are something!  The only one of the 16 I blew the motor on was an old undermaintained 1978 1600cc.  It was my fault and not the cars

    You had a pin that exact size in your hardware!  Wow man!
    I'd fly it like that, but my "imo" aint worth much..  lets hear some sage advice from guys like Jim, Ed, and others.
    The washer stop would give me more pause, since it could bend and get jammed in there.  But that is so dang unlikely.

    There's at least 3 guys here that have subaru parts for sale, so id bet you'll find your part.
    Mine is a NSI subaru that I am looking to sell to a NSI guy that wants a complete engine as a parts wagon!

    My wife has had a passion for studying alternative cancer treatments. In her briefing to me of what she has learned, I am convinced that there sure are many great avenues out there.  So many in fact that it would be hard to choose a plan.  I really do believe that some of those ideas are sound, and can tremendously supplement and increase the effectiveness of the big pharma / medical methods.
    Please take some time to research those options, and I'll put a prayer in for ya... for healing yes, but even more a prayer that you will find your way to the plan of attack that will be the most effective.

    That's a nice compliment to my first attempt at a motor mount.  Thanks!
    But like with Leni's new bush gear design, I would want to test this out a bit, prove it out, and look for possible improvements before considering having other people copy it.
    There are a lot of KF 5-7s out there, and I think the 4 uses a very similar mount.  I've also heard that the RX-1 and Apex use the same mount, so it is possible there may be some interest in it I guess.

    New plane for me, not real nuts about the door latch.  Works great, but it is a little tough to get to and open from the cockpit  in a hurry (egress).  On the to-do list to modify.

    Flashing and buzzing panel indicator light.
    Found this while researching for an oil level low light.
    Might be a nice upgrade to warning lights for critical items.
    Flashing and buzzing would be good for me since I'm always looking out the window when I'm up flying!

    OIL LEVEL LOW WARNING LIGHT 
    I checked the oil dipstick in the yamaha oil tank.  It has a float switch integrated in the dipstick that senses oil level.  The two electrical leads to the dipstick have continuity when the oil is low, and are open when oil is adequate.  Looks like it would be simple to wire up a panel indicator light for low oil.

    CARB CLEANING AND RX-1 SHOP MANUAL:
    The most common question on the RX-1 snowmobile forum seems to be regarding rough running old sleds.  The canned advice I see a lot is "clean your carbs and post us in the morning".
    I posted a reprint from an expert in the snowmo forum on how to clean these carburetors.  I also posted the RX-1  APEX and C Box service manuals here:

    RVSimons did a beautiful job of cleaning up my carbs and supplying me with new orings for float bowl covers and main jet towers.  Thanks Vance!
    I decided to go totally new in there and also bought the needle and seat kits which includes orings on the back side of the seat.  If they get crusty (see pic), pressurized fuel will leak around the seat and flood the carb.  My sled had that trouble and I just cleaned em up.  In the plane I want new.

    I'm a moron, but I was able to hit my very first fitup nuts on with the first grind!
    Trick #2  is to make templates for both ends of the tube, wrap them on the tube and tape them up so they will still slip off.  
    Next sleeve the two paper tubes together and fit them up on your work (paper tube only, see pic).  Spin and slide them till they line up and contact perfectly, then tape the two halves of the paper tube together at that alignment and slide them on the raw tube.  
    Mark the tube with a sharpie and grind both ends perfectly in one shot.
    For longer sections of tube, I made my paper tube template with an extra section of rolled paper between the cope templates.

    RX-1 ENGINE MEASUREMENTS  (with Skytrax adapter and c box attached)
    For anyone considering this motor, here's some rough measurements:
    Total length is right about 27.75" from back of motor to prop hub.
    Total height about 18
    From engine top to prop center is about 7.5"
    Width about 13" (without exhaust or airbox)
    Some tilt of the motor could be done (my install will be fairly vertical (see pics).  Tilting would make overall height slightly less (16 maybe) and width a little more (15ish).  Tilting would also bring prop center down and left slightly.
    In my install, I am aiming for the prop hub to come out exactly where the subaru did.  This will require a hood cutout and "bubble" on the top to allow for the cylinder head to protrude about 2.5 inches (the subaru cowl was sloped down alot since that motor was a boxer: wide and not tall)

    TUBE COPING / FISHMOUTH TEMPLATES
    Starting in on the mount.
    You smart guys already know about this, but for anyone like myself who didn't know:
    Go to the site below and enter your tube dia, thickness, the angle of the joint, and the mating tube dia.
    You get a printable template that you can trace to make a perfect grind on the first try.  Way too cool!

    And another quick tip from the sled heads.  Get sst socket head cap screws to replace the phillips heads holding float bowls on.  The damn phillips ones round out waaay too easy.
    Size is M4x8
