    Thanks - That is interesting - I thought the only benefit for the HS was better elevator control - same thing for VS and rudder. If you haven't read Doug Holly's post in files about the VGs and the Harry Riblett modification, then you should read it.Good Flying,

    Parting out my Avid AF-1
    I bought a 1995 Avid that was significantly damaged on the way home (Trailering accident - Right wing unfolded and hit a tree). The gear, tailfeathers, left wing, firewall forward including the engine (532 Rotax/60 hours TT), prop, motor mount, radiator, & all instruments are undamaged.  Left wing is repairable, A purpose built Avid trailer is also available. I would like to sell it all as a package for $3500.00 firm.

    A friend of me, actually my flight instructor, has put VG's under the hor. stab approx 4 inches before the stab/elevator separation. It gave him an astonishing 20 kM/hr max speed increase at his 912 powered apollo fox. Speed was 180, is now a little over 200 kM/Hr

    Take care with the in-line fuel valves, See the topic Air/vapor lock in general. I had two engine failures due to the valves.

    air/vapor lock in avid flyer
    I am Nico van Dijk, living in the south of Spain and owner of a stol avid flyer EC-YFP. Engine Rotax 582 After flying approx 25 hours total in this plane, I had a engine failure at take-off. I immedeately did cut the engine power and could brake in time. The engine remained running. After checking about everything, I could not find any problem. In order to be more sure, took the carburetters apart and cleaned them. Nothing found, no water, everything very nice and clean. Checked for water in the fuel again, nothing. Checked the free flow at the position of the fuelpump, approx 0.7 Litres/minute, ok. So I mounted a fuel pressure meter and a fuel level alam at the header tank and tested the engine at ground, all OK. I did take-off again, EG temp ok, power ok worked very fine. A week later I flew at 5400 RPM and had en other engine failure in air. Did cut the engine wich remaied running at 2000 RPM and looked for a place to land. While doing that, I saw the fuel pressur rising to normal, opened the engine slowly and could return to the airfield. There I tested everything again and found the problem, air or vapor lock. From the wing tank I had a small fuel valve from Aircraft Spruce number 05-0104x mounted in the line going to the header tank. There is an other of such fuel valves for panel mounting in the panel in order to prevent that the carb's flooding when parked for a long time. During a test run, I saw a vapor or air bubble underneath the fuelvalve between the wing tank and the header tank. This bubble did not pass the fuelvalve and did completely shut-off the fuel flow. After a few minutes, the fuel level in the header tank lowered and my alarm went off. I knocked the airbubble wich bit by bit started passing the fuel valve. As soon as it was gone, the fuel started flowing and the level in the header tank was restored. I checked the main tank end the fuelvalve for debris, were perfectly clean. So I took the fuelvalve apart and... surprise. The connections are 5 mm interior, but the valve has only a throughput hole of 3.15 mm (half the expected flow!), leading to the vapor lock problem. The bubble and the fuel can't pass each other in this small hole. I mounted a fuelvalve with a througput hole of 6.5 mm and the problem was gone. But there is an other such valve in my panel. So also vulnerable to Air / vapor lock. In order to prevent that I did mount a Facet pump (low pressure!!) near the output of the header tank so the rest of the fuel system is a little pressurized. So far everything is fine again. Fuel pressure at the Mikuni pump only approx 4 PSI, At the Facet pump only approx 3 PSI, when both on, 5 - 6 PSI I contacted Aircraft spruce about this. I explained, but no results yet. I think that the fuelvalve should have throughput hole the same size as you can see at the connections. This situation is dangeroeus and a vapor or air lock can happen any time. When selling fuelvalves, the seller should advertise the throughput hole!!! Kind regards Nico

  14. C5Engineer added a post in a topic Width of gear   

    10" wider and 3" taller. Too many variables to give a real number on takeoff distance. I noticed it more on landing. You can fly an approach with power at least 5mph slower and not hit tailwheel first and you can stand on the brakes with no feeling that it might tip over....I have custom brakes on mine that will allow you to dump it on it's nose if your not careful.

    Width of gear
    How wide is your bush gear and how much does it raise the front of your plane. How much does it shorten your take off roll.

    Thanks

    This looks like something Steve Henry would do in his Highlander except he would of been taxiing at 30 mph with his tail up. Looks like he get's hung up in the trees at one point.

    Cord line
    What angle is your cord line and how long is your average takeoff roll. Will be building new gear and am looking to do it right first time. Since all our planes are the same but different I thought pooling the info might give me some direction in the construction of the gear. Thanks for all your advice, it has clarified and simplified my rebuild.

    Been there done that once! I also had a passenger. Some nasty winds came up while my Dad and I were visiting a one way backcountry strip. As soon as I got above the treeline I got hit with a nasty tailwind and began descending into rising terrain at full power. I finally gave up and used all the energy I had left to rack it onto her wingtip and go the other direction. As soon as I got some wind over the wings she started climbing again. That is bad bad feeling settling under power at any time but especially close to the ground! It goes against all your instinct to push the nose into the trees but you obviously did the right thing.

    Great stuff Jack....Thanks for posting! Sorry I missed your Bday party that we spoke about earlier this year things got hectic on that trip home with my 3 year old in tow. I saw some pictures of that counter rotating heli fighting the fire that was in Orofino last week. Cool design! Hope things are going well in the Valley. Say hi to Wicks, Otey, and Dean for me.
