  1. 1avidflyer added a post in a topic Replacing a Whelen strobe unit   

    I have a few sets of them myself.  It's a shame when you look at the cost of these things, but I guess time passes by and technology improves and stuff gets left behind.  The thing is the light out on the wingtip is pretty good, and mainly it's the big power supply for the strobe that is the problem in my opinion, especially if you can go with LED light bulbs for the nav lights.   I have some fire alarm strobes like what you would see in a hospital or other type public building.  They run on 12 volts, as well, but have a smaller strobe light.  They weigh next to nothing though, just a circuit board, and some gizmos soldered into it. Would be nice if I knew if they would trigger the whelen strobes.  I'm very ignorant when it comes to electronics, (some would say "in many other fields as well"  but we wont listen to them at the moment.  JImChuk

    Replacing a Whelen strobe unit
    Just wondering if anyone ever made a modern unit to fire the whelen strobes.  There is a lot of stuff in that whelen power box, and it sucks up a lot of juice.  Must be a better way (besides LEDs)  I would like to keep the wing tip units, but get rid of that power box if possible.  JImChuk

    The rib tails should be strong enough for flight if there is no damage or rot in them.  The very first Avid A models didn't have the flaperon counterweights, and there was a report or two of flutter.  All Avids after that should have had them installed.  If the rib tails are in good shape, I wouldn't worry about them, but look them over real good if there is any doubt.  JImChuk

    Avid did some testing after one of the owners ended up going down after his Mikuni pulse pump failed.  With ram air tubes on the fuel caps, the 582 engine would run on gravity feed alone  and push fuel through the  pulse pump.  The more things on a plane, the more things to go wrong....and at least in my case, the biggest possible problem is sitting in the left seat!

    Bing 64 (like used on the 912) and bing 94 that Jabiru uses cannot take a lot for fuel pressure or they will start bypassing the float valve.  That is the problem I had before I got rid of the mechanical fuel pump.  That was the reason for a dead stick landing.  Rotax's newer 912  fuel pumps produced more pressure then the early ones, and that is why they now want you to use a return line back to the tanks.  Can't say for sure on the type 54 like is used on the 2 strokes, but I suppose it is limited on the pressure it can take as well.  JImChuk

    I have an electric fuel pump on my Avid MK IV.  Engine is a Jabiru which has a mechanical fuel pump that I eventually removed because it was making to much pressure.  I only use the electric pump for take off, and let gravity and the ram air tubes in the gas caps do the rest.  It worked tonight for .6 hr, and has for the last 2 or 3 hundred hours.  I never ran one with the two stroke engines though.  JImChuk

  10. 1avidflyer added a post in a topic I need a Kitfox 4 wing rib   

    The flaperon ribs were made from thicker plywood.  Just looked at my manual, and it says the trailing rib web is made from thicker plywood on the flaperon ribs.   I believe you are right that it was 6MM thickness.   I may have a loose rib that I can measure.   6MM is pretty much 1/4" and you can get that from Aircraft spruce or Wicks in 12 ply.  I would probably use that on all of them if it was me.  JImChuk

    Allen, how did you do back when you were flying my Kitfox 4?  JImChuk

  12. 1avidflyer added a post in a topic Avif vs. KitFox actual versions comparison   

    The earliest Kitfox 4 had a gross weight of 1050,( later ones are 1200).   Avid C with the heavy hauler wing option was 1050 also.  The Kitfox 4 and later use a wing that doesn't have a uncambered wing, and cruise faster because of it.  The Kitfox 4 has 2" more headroom then the Avid (at least with the Avid MK IV, but I believe the C model is the same in this regard).  Also, the Kitfox 4 is about 9" longer between the wing and tail then the Avid.  That should help the ground handling some.  Flaperon mixer controls were very similar in the Kitfox 1-3 and the Avids.  Kitfox 4 used a different system, and it helped to eliminate some of the adverse yaw.  Also it opened up the area behind the seat for a better baggage area.  Wingspan on a standard wing Kitfox 4 is 2' more then a standard Avid Flyer.  Kitfox is likely to be somewhat heavier then the Avid Flyer.  If they were the same price, and equally equipted, the Kitfox would be a better buy.  JImChuk

    It does look nice.  I think you will miss it when it's gone.  JImChuk

  15. 1avidflyer added a post in a topic Avid Model C - Gross Weight   

    I've never seen or heard of a MK IV that didn't have either a heavy hauler wing, or speed wings.  The C model with heavy hauler wings has a gross weight of 1050 as I remember, but improvements in the fuselage on the MK IV caused it to be raised to 1150. JImChuk 
    PS  Avid supposedly eventually said the gross weight was 1200 on the MK IV, but that was probably because Kitfox 4 went with 1200 lb. gross weight and there was competition going on
