  1. Original from the factory, Rotax 912 Muffler. Exhaust pipe size is 1.250" Tail pipe is 1.75" and muffler OD is 4"

     This has approx 30hrs. of use on it. I added the flat strap between the muffler and tailpipe per Avid SB.

    $300 shipped to the lower 48

  2. Thanks Chris. I didn't use certified scales when it was weighed but I came up with 667. As far as gas goes I assume you mean 6 GPH? If so I don't have the fuel flow option installed but, if I remember correctly for flight planning purposes I was burning under 5 gph at 52-5300rpm and cruising mid 90's.

  3. It's time to sell the Avid Bought by my father in 1990 and stored shortly after for 20 years. I bought the kit in 2011 and received A/W in 2014.  Serial number 846 which makes it a model C but has many MKIV upgrades including the baggage compartment and dual wingtanks.  I raised the roof during construction to give an additional 3" of headroom and extended the aerobatic speedwings.

    Painted with Stewart Systems Ekopoly

    mid 90's 912ULS with approx. 350HRS since new. Engine was inspected at LEAF when I bought it. (have log book entry)

    Ivo medium 3 blade prop

    Dynon D60 

    Garmin GTR 225 com.

    Garmin GTX327 Transponder

    EIS4000 engine monitor

    PS engineering intercom

    AeroLed Nav/strobe and LED landing light

    Cabin heat supplied by engine coolant

    Upgraded Matco master cylinders and brake pedal geometry

    ACK406 ELT

    Electric trim

    Full interior with sale (not installed) including fiberglass pan seat and sling seat.

    It's configured as a tri-gear currently but has a set of taildragger main gear with taller tires and a Matco 6" pneumatic tailwheel included that were installed and flown briefly.  The conversion also received FAA approval and has the proper logbook entry to switch the gear anytime. 

    Tow-bar for short distances and full set of wing braces included

  4.  Like the others with engineering backgrounds are saying, just dress out the scratches, and patch over the fabric, and you'll be fine.  I say this with confidence as an ex-professor of aerospace engineering, and designer of a couple of my own hang gliders with tubular spars, where it was my butt on the line.  The Avid (even the STOL) wings are quite strong.  My STOL wing, with me flying alone, is good to better than 6 Gs based on Avid's static test.  I nust admit I have not analyzed, so don't know about the H-stab, though.  I don't know if anyone has bent one as yet, though, but I doubt it.  Oh yeah - but it's not my butt...

    Really???? 

    Almost a .070" gouge out of a .083" thick spar needs some definite surgery to make that safe.

    You guys recommending smoothing that out need to look at the first pics again and take note the amount the digital caliper is open. 

    The original post stating .006-,007" doesn't come close, apparently using that mode on the caliper throws people off. You can barely see a .007" gap between the caliper jaws.


  5. I added three feet. I think that makes it the standard long wing length. If your wing is already built it wouldn't be the best idea to extend it more than 3' if you've built in the washout that the plans call for. The 2" of washout adds a lot of drag and extending beyond 3' could make the negative performance outweigh the benefits of the longer wing


  6. I used Avids instructions when I extended my aerobatic speedwing. Use a 12" piece of .083 spar with about a 1/2" strip cut out lengthwise. mark a line at 6"and put a slight taper on both ends. squeeze with hose clamps and insert into the spar 6" I found a drill pattern online but there wasn't anything special about it. Pay attention where the slot is located and don't drill to close to those edges.

  7. here's a couple pics. just make a template from cardboard and cut a notch that will fit under the rear brace tube. I have about a 1/2" overlap in the center and there attached with some 1/4 long sheet metal screws into the tubes

  8. To make a long story short, after a recent diagnosis of Rheumatoid Arthritis, being 6' 2" tall and having joint pain issues in the knees I'm considering selling my 2014 Avid model C approx. 60hrs. with raised skylight and turtledeck. 912ULS(350ish hrs.) extended aerobatic speed wing.

    The plane is setup as a Tri gear now but I have the complete setup for tail dragger including a set of main gear and matco 6" tailwheel. The conversion to tail dragger was complete and approved by the local FSDO after I completed phase 1 and is noted in the logbook, including W&B.

    The Kit was purchased new from Avid by my father in DEC. of 1990 and stored after a couple years. I started construction in 2011 and first flight around June of 2014

    I know the value will be nowhere near whats been invested but I'm looking for opinions on how to value this.

  9. I've got the 3 blade 72" Ivo medium on my Avid with 912ULS and it's smooth as glass.

    Thanks Birddog.  How does it perform and have you been able to compare it with 912's using other props?

    I'm not sure how it compares to other Avids but I have it adjusted for max 5500 climb RPM at 1500FPM solo and cruise at 100 at 5000RPM.

    I've used two different wood props, a Warp and Powerfin on other light planes and the Ivo seems to be the smoothest.


  10. I'm not sure which came first, the aluminum or the fiberglass but they served the same purpose which was to make a smooth surface over the false ribs on the top of the wing.

    This sold almost immediately via PM.

  11. I moved them out on my extended speedwing. The wing tip is still flying long after the root has stalled if the wing was built to the plans(2" washout if extended) giving roll control at a lower speed.

    If the wing was built with little to no washout initially it probably wouldn't make a big difference where there attached.
