  1. saskavid added a post in a topic Matco tailwheel issue   

    Ok then that idea is shot. didn't realize the bearings sit on a tube independent of the bolt and nut influence to side loading. In terms of bearing life I do know some of the chinese manufacture bearings that I've used to replace worn ones on my combine have demonstrated fractional service life compared to the ones they replaced. 
     
    Jim: just out of curiosity how much play is there between the pipe and the bearings laterally when everything is assembled?

    Just at a glance I'd say/guess over torqued axle bolt and created an excessive side load on the bearings. looks like there is a grease type wetness in the wheel and the race covers.In terms of matco using any of our ideas...I know with the original matco front wheels on the avid where the inner race wants to spin on the axle because of excessive seal drag the best answer is some kind of plastic spacer between the inner races to moderately pressurize the bearing and overcome the drag. Matco's best answer is to just add unnessicary drag by tightening up the wheel nut until stops spinning on the axle and that the added drag of doing this inconsequental to the energy profile of the aircraft. They don't consider that the added nut torque with added vibration and conditions of side load will slowly over time with use lead to base metal compression of the alloy wheel with the super hard bearing cup pushing into the magnesium alloy or whatever it is.. Of course this is all just theoretical observation on my part.

  3. saskavid added a post in a topic Avid Heavy Hauler Statement of Conformity   

    It just effects the legal ability of the aircraft to carry people who would be labeled passengers. A basic ultralight can't carry passengers. The advanced one can. Basic ultralight can carry passengers provided the other person has a pilots license or the purpose of the flight is to provide dual instruction and the person flying the plane has an instructor endorsement.

    So did you sell this plane and buy it back at a later date?If you are the builder if the plane any you have visual records and a log of the work you did you might have a chance of working with a designated inspector and getting it signed off into the experimental category. Mine is basic ultra light started out its life as an experimental. Was told it was possible to go back with some work and inspection and such.

  6. saskavid added a post in a topic "E" type rudder Pedals   

    So avid aircraft to my knowledge never made an "E" style rudder system. Denny aircraft did introduce a rudder pedal brake pedal system with the model 4 that they referred to as the E style. What factor of geometry are you looking to improve? How the rudder pedals work and fit to your body or improving the performance of the brakes?

  7. saskavid added a post in a topic rotary valve oil being pushed out the reservoir bottle on 582   

    Is it an inverted mounting condition? the level in my reservoir does increase a bit when the plane is at operating temps but retreats when it cools back down but isn't forcing it out the top of the bottle....

    A 65 fastback with cragar ss rims... I am absolutely green right now just looking at it.... This is going to be an amazing plane when you are finished and flying.

  9. saskavid added a post in a topic Engine Mount Rubber   

    So someone with more knowledge then me will have to chime in on what I'm seeing and going to say. I am seeing what avid called the dyna- smooth engine mount that was introduced when they were producing the mk4. I thought the aluminum "channels" were supposed to bolt solid to the engine and the only place there was supposed to be rubber is in the ends of the channels where they bolt to the engine mount?

  10. saskavid added a post in a topic 109JB got another wrecked Kitfox   

    So I'm just going on memory here but I had a conversation with a rotax tech named Bob Robertson a long  while back and If I'm remembering it accurately at full throttle the needle is no longer having any influence on the fuel mixture only the main jet is. With regards to idle I just let the hacman make the idle mixture work. If you land somewhere a thousand feet lower elevation after dialing it in with jet changes it will possibly be a bit leaner than ideal.

    Sorry Tjay what I'm trying to ask is was the mixer on the antique 1930-1940 museum plane like an early kitfox/ avid style or the newer kitfox 4/7 you built for your plane?

  12. saskavid added a post in a topic Flaperons   

    So it was the same mixer as the early kitfox/avid or the newer mixer you built?

  13. saskavid added a post in a topic 109JB got another wrecked Kitfox   

    To my memory the commercial hacman did start out taking the "reference" air from inside the carb air filter and at some more recent point has went away from that to using an independent filtered port . The hacman I made for my own use some time ago was done with the independent filtered port and increased main jet size because it is a model C avid with the carb intakes walled off from the rest of the engine and exposed to a more pressurized atmospheric condition.

  15. saskavid added a post in a topic Avid Mk4 aerobat - wing replacement question   

    One thing to keep in mind as well when and if you are going to redo the holes for positioning the flaperons is the angle between the flap bracket and the top of the wing is at the trailing edge is supposed to be 54 degrees for a speed wing, manual specified and for the inboard and outboard brackets is labeled critical.

    You could try scratch doctor and an orbital buffer. I've done it once. Help get rid of the surface oxidation maybe so the light doesn't catch the fine scratches so intensely. Worth a try that won't have you out of pocket that much...

    Sad . Was a good looking plane at one point.

  18. saskavid added a post in a topic Bush gear failures   

    One thing you could try is to put a couple of pucks in the lathe and machine a bit of an angle into the face of one end on a couple of the pucks say to produce an included angle of 150 deg. instead of perfectly flat.... for say 50% of the face of the puck. put them top and bottom of the puck stack and it might soften initial travel a bit.

  21. saskavid added a post in a topic Rotax 582 RaDIATOR CAP Woes   

    So I am just pondering the cap/psi change and wondering what is going on?Back in the day I thought they wanted a lower psi to protect the rotary valve seal and keep from blowing antifreeze into the rotary valve oil. Think mine is actually a 10psi on my plane but just wondering why the move to a higher psi.

    guys were running fuel with 5% ethanol in polyester resin tanks and having no issues by having a 100 to 1 mix of 2 stroke synthetic oil with it.... might be possible to stop some of the degeneration by doing this in a lesser ratio that won't be detrimental to the motor's functionality.

    Well you have had exposure to creativity that is for sure and that is Half the battle and will get you 5% of the way there to building an aircraft successfully. Having an aircraft like an avid has taught me more about physics than I could ever glean from just classroom programming, and if it is there to be had for you you will get it the same way. Remember that Dean Wilson never formally finished high school says a lot about the man he is and what the education system basically isn't doing.
