    I can read those dimensions - What's wrong with this one?  EDMO

    From what I understand, they will accept even a hand-drawn picture - Cant you write in your own measurements on the drawing?  EDMO

    Doug,  How many gallons do each of your tanks hold?  I can see a huge twisting stress difference in your short tanks and the long tanks that Avid showed.  The long tanks don't look like a good idea.  I second the motion for short plastic tanks - weight difference should not be a problem - just cost of tooling up to make them.  Somehow, other kit makers have managed to do that. 
    Kitfox and Avid used to buy their tanks from the same maker - Ron's Fiberglass.   EDMO

    I would be totally happy if someone kept good records of their Kitfox performance with either droop trips or the Hoerner tips, and then took them off and put flat plates on - then recorded the new performance.   I think it would be somewhat like shortening the full-length wings to make speed wings.  EDMO

    No reason not to try for the best of both types of performance - Guess that's why Kitfox changed to the Riblett airfoil and gained cruise speeds while STOL remained the same.  EDMO

    Extending spars and adding another rib with a flat plate 12 or 18" outboard keeps you from losing wing area, so it should be the same as adding squared tips, although the drag factor is maybe not as good for cruise speeds.  I think Steve is more interested in STOL performance than tip drag.   I agree,  the Piper-type Avid rounded tips are not good performers.   EDMO

    I forget how long the droop tips are, but let's say 16" each, so you are losing 32" of wingspan which will decrease the amount of lift - there is also a drag factor involved.  A tip like the Hoerner tips, or an extension cut at an angle on the bottom, would be better than just a flat plate which does nothing for lift or shedding the vortex away from the top of the wing to reduce drag.  There have been wind tunnel tests to prove this.   If the flat plate was better, then the short-wing Pipers would have done that long ago instead of adding the expensive squared Hoerner type tips on their birds to get better performance.  See my post about their findings.   EDMO

    I think I must be related to Sgt. Schultz:  "I know Nuh-thing!"  Ha!  Sometimes I need someone to help bring me back to what I should know already!  EDMO

    My Big One Joey - somehow totally forgot that there was FG under the fabric on Avids - I even owned a pair at one time and sold them!   Must have confused them with Pipers!  Thanks,  EDMO

    Avids didn't have FG tips - Is he wanting to use Kitfox tips on an Avid?  I've got a set of used droop tips.  EDMO

  15. EDMO added a post in a topic INVERTED TAIL RIBS QUESTION   

    Leni,  I know folded width probably wont matter to you because you don't trailer - But, have you figured how much you would have to shrink the 35b, or if you do, to fit your bird?  I think those are about 10" longer chord than the 51" Avid including the flaperons/ailerons.  I've got about 14 aileron ribs for the Pipers/Maule - Maybe D&E made - ridicules how much they want for those!  EDMO

    Don't you have to have a 2-blade hub to do that?  You could do the same with Warp Drive and 2 hubs.  EDMO

  18. EDMO added a post in a topic Pouring lead into the rudder??   

    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

  19. EDMO added a post in a topic Amperage reading- 912   

    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

  20. EDMO added a post in a topic Nose ribs   

    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

    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

  22. EDMO added a post in a topic Step 2, Build Magnum!!   

    Seems like I usually needed 2 rings instead of 1 - One to put my hand thru and one to look thru to see what I am doing, or see how bad the bleeding is!   In Avschool we had to safety a turnbuckle inside of a pipe that we couldn't see thru - They had to sterilize mine from all the bleeding I did!  ;<)  I love the new turnbuckles with clips instead of safety wire!    EDMO

    Yes, you can get 1.25 and 1.5 with the same bolt pattern - But those size axles on factory planes may have different bolt patterns - usually the 1.25 (Cessna?) are a square pattern, and the 1.5 (Piper?) are a rectangular pattern.   I have had both patterns.   Check Grove catalog for patterns they sell.   Should be simple to make mounting plates with no holes and let the buyer drill them to match their axles if they choose to do that?   EDMO

    Grove makes several sizes of bolt-on axles with different bolt patterns too - Not to mention that there are used Cessna, Piper and other bolt-on axles you can use with their wheels or others.  I totally agree that the original 3/4" axles are not going to last if you are heavy and bumping rocks, etc.  Isn't that is what Bush Gear is for?
    BTW:  I have some new Kitfox 3/4" axles if someone needs them - may have a set of Cessna or Piper axles too - forget what size.   Check Kitfox prices and send me a PM.   EDMO
