    Not enough to know about, I get to many projects going. Hope to get back to it before to Long.

    Nice!
    Hopefully I'll get my plane done and we can get out lake hopping someday!

    Mike Hair did my exhaust. Nice guy.
    How many hours do you have on the 670?

    I also changed to premixing, partly to insure I always had enough oil and partly weight and C.G.as the engine and exhaust system is heavier. Mike Hair is my neighbor and helped me build the 670. I then helped him with the build of a 720 (670 bored to accept Polaris pistons). I ran my 582 for 700 hours trouble free but was getting concerned about the high time. I also had a leaking oil injection check valve for the latter part of that and thought this is a way to eliminate this problem.

    I think that is pretty bad ass.  Bend a tube and you unbolt it and slip a new one in.  No chemicals to deal with in the covering etc.  When you end up with enough duct tape on it from field repairs you just unlace the covering and zip on a new scheme.  Not too much in the video showing TO and landing performance though.
    Outside the box thinking and creativity in bringing new products to market gets a forward nod from me!

    Getting a length of 1" or 1.5" aluminum channel to lay across the ribs makes it really easy to clamp and glue the false ribs into place.

    I can bend some up if you want one but it wont be chromed.  I get home the 20th and can knock one out for you.

    Ron Davis asks for pre-mix as a warrenty term, so I am pre-mixing at 40:1

    Yes - There have been instances where air pressures on large unshielded horns have even reversed the forces on the controls - This becomes more critical with faster flight - Usually this is corrected by cutting back the horns shorter, or also putting a solid part of the stabilizer in front of the horns to make them sheilded.  The weights in the horns may help prevent this.  EDMO

    I had to remove all of my MK IV false ribs (both wings) due to the aluminum leading edge being a real mess. With a heat gun and patience, I was able to remove them all, clean up the spar and then put them back in place. A taut line from wing tip to root made placing them back at the correct height pretty straight forward. And then I replace the aluminum with a thin veneer of plywood.

    The starter takes a heavy amperage - the battery will need a quick charge from the alternater after you start engine.   The length of charging time depends on how long you have to use the starter to start the engine.   Disconnect the tender before starting.   EDMO

    Are you going with oil injection or premixing.

    RJG,
    In my opinion, the rudder is facing into the wind most of the time, so wind forces will not help balance in any way.  Hope I am understanding you correctly.

    Yes. My assembly manual calls them nose ribs.

    ahhhh, so it only will show charging if the battery is a bit low? It has been on a tender all along so Maybe its fully charged and not charging then

         Would the horn itself (being in front of the hinge pivot point) catch air and lighten the elevator/stick and rudder/ peddle forces
    thx rjg

    Was trying to figure out what you were talking about, I'm guessing you mean the false ribs? (the little ones between the big ones)  JImChuk

    Yeah, I've got 3 or 4 broken ones. Haven't got that far yet.

    They should be same height as main ribs - guess someone didn't measure when gluing them in - it should fly OK that way, but shrinking fabric may possibly put enough pressure on them to bend or break them.   The easiest solution that I can think of is to glue some 1/8" thick capstrips on the tops of the main ribs to make everything even.  The nose ribs break very easily - just how do I know that?   I have mended lots of them!   EDMO

    Vance, did you have a chance to check if you had a control stick? If you have one I am interested in buying one. I have a Granddaughter that I want teach.  Thanks

    Nose ribs
    Just noticed that the nose ribs on my wings are about 1/8" taller than the other ribs. Do they have to be sanded down? Lot of sanding.

    Turn off all accessories before you start the engine - the ammeter should move to positive as soon as engine starts, then as soon as the battery catches up on charging it should move back to about neutral or a little above.   EDMO

    Ok, so I turned on the master and then one by one all of my accessories. The needle went down a tiny bit for everything I turned on, so I guess its working. Guess Ill start up the plane this week and see if I can get the needle to move up with some RPMs. I started this plane for the first time a few days ago and noticed the needle didnt move but maybe my accessories were sucking up as much as the little generator puts out at relatively low rpm.

    With the way I have it built if should easily handle 1200 lbs now I see no reason to fly like that but 1050 should cover all the weight I need.
