    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

    My folks left England about 400 years ago - Maybe they couldn't get their Davinci glider certified there?  ;<)  EDMO

    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

    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

    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
