  1. wypaul added a post in a topic Gear swap... Number 3...Bush Gear part deux   

    Thanks for the update Joey.  I noticed that you did not show the cabane (vee), was anything done to it to beef it up in the new version?  Also was your first set of springs the yellow ones?  I have the Highwing version and it shipped with the yellow springs.  It did settle about 5/8" when the weight of the plane was on it but seemed somewhat stiff.

    I haven't quite figured out this new format and have trouble figuring out where to make the attachments yet so I will try this again.

  4. wypaul added a post in a topic 912 Carb Balance   

    Chris,

    I will be the first to admit that I am new to the business of carb balancing so my views are open to change as I learn more about this. What the CarbMate indicated after balancing the carbs with the neutralizer spring in place is the balance remained in balance through the range of throttle movement with slight flicker to the right at one point. My guess is that the balance tube will handle that slight change. When I get a chance I will check with the Mate hooked to the primer lines and the balance tube in place to see what happens. One other note is that the spring does not neutralize the throttle springs totally but does reduce the pull substantially. The carbs will still go to full if one of the throttle cables going to the carbs fails. Will check to see what happens if the cable to the splitter fails by disconnecting it.

    Good point on the full throttle AV8, saw your post after I posted above.

    If you look at the picture that I posted of the cabane failure you can see that the cross tube failed and deflected downward.  I think the simple added tube may have stopped the fuselage damage but without actual testing there is not a way to tell.  One thing for sure the cabane, which is a truss, would be stronger.  I am sure that infilling the seat truss would have been more important is limiting the damage to my fuselage and that is in the works.

    I have added the neutralizer spring to mine and would be interested in why you think that this is a bad idea.  My setup allows the carb springs to still maintain slight pull.  By the way AV8r3400 I didn't catch your first name.
     
    I don't think that the engine would run good with 2 cylinders on one side doing the work.  My thought is to do what several others have done and buy the pricey split cable that ACS sells.  Others might sell this as well.

    I have the Jabiru 3300 on my Q-2 and the spring was removed so it works as a push/pull setup.  The throttle throw is very short and the movement of the throttle is short also, about an inch or so.  This could be increased but haven't seen a need to do so.  It now has over 600 hours and works great.  It has the standard friction aircraft cable.
     
     
    Dang, I talked myself into ordering one today.
     
    Doug I don't know why the Rotax and Jabiru are setup that way.  At least with the Jabiru it is a single carb so it won't shake the engine off the front of the airplane.  I wonder if Bing may require it or maybe the lawyers had a hand in it as was mentioned already.

  8. wypaul added a post in a topic Fuse length and new gear   

    Jim I see what you are talking about. Maybe a plate coming down from the seat truss that could bolt to the cross member on the cabane. I am going to do some infilling of the seat truss and also in the small triangle on the bottom just ahead of the gear attachment point where mine bent and kinked.

    Have you purchased springs for your gear yet? If so did you get the springs that were mentioned in the Yahoo Group file from McMaster-Carr. My gear came with a stronger yellow spring(Die springs are color coded) and I am thinking that it may be a little to much spring. I did find the red spring at a better price here:

    Also I talked to Mark at Highwing LLC about the added king post in the cabane that we have been talking about. He is going to talk to Lowell, his partner but thought that it would be a good idea.

    I think that Joey remove his bush gear but I am not sure. Maybe he would comment about his experience.

    We have hijacked this thread, maybe we need to start another thread so the subject can be search easier.

  10. wypaul added a post in a topic Fuse length and new gear   

    I will take the release off of the tailwheel before I try this again. My first thought was to convert to the tri gear but don't really want to do that.

    David I looked at the video of the Grove gear test and I am considering that route. What does it take to use the Matco wheels and brakes or are different wheels required for the swap?

    I hate to give up on the spring gear but I really have all the experience I want repairing the fuselage. I will be doing some reinforcement of the fuselage while I have the fabric off for repairs.

    I have some photos of KF brake setup with the MC mounted to the floor and different pedals. I would like to see what is working for others so I am not spending time reinventing.

  11. wypaul added a post in a topic Fuse length and new gear   

    Ok I have some more photos of the damage to the fuselage.
     
    I wish I knew for sure but from what I know is that on landing as the plane was slowing down and then the ground loop.  I did bounce the plane a little on touch down so the question is was the gear damaged in the bounce or in the ground loop.  My thinking at this time is that the tailwheel released and caused the ground loops but I really have no idea.  I set the bakes so they were very hard to reach this time so I am fairly certain that I did not get on the brakes.
     
    I have 800 hours in a Q-2 TD which is pretty twitchy on the runway, with no ground loops so I am baffled with the problems that the Avid is presenting.

  12. wypaul added a post in a topic Fuse length and new gear   

    Jim, that is correct.  In addition the bottom longeron was bent ahead of the gear attachment fitting.  Also as I mentioned the top member of the cabane cross member buckled.  I am not sure if this happen in the ground loop or if it happened in a slight bounced land.  The good news is that it stayed on its gear due to the wider stance and did not get the wing.  I am 2 for 2 on the ground loops/ fuselage damage and now thinking about the tri gear.  I will do some fuselage beefing this time to take care of the weak points in the gear and the fuselage.  I have a picture of the damage to the gear now and is attached.  The other pictures will follow. 
     
    I think that the spring on the gear is to strong for the weight of the plane.  This is the gear sold by Highwing LLC but I think that the Airdale gear uses the same spring.
     
    As you can see the cross member could benefit IMHO from a brace going from the top center to the center of the vee and also a heavier top tube making this a much stronger truss.

    Leni, I have the new spring gear and the bent fuselage.  I was wondering if you have any progress on your idea for a fix.  I have the fabric pulled away and can get a good picture of the damages tomorrow.  I had hoped that the cabine vee would help carry the load but the side to side bar, top of the vee buckled allowing the side of the lower fuselage tube to buckle inward.

    CarbMate
    Just completed carb sync on my 912 again this time with the CarbMate.  Last time I built a manometer and spent a couple of unpleasant hours getting it sync-ed .  This time spent about 15 min and it was a breeze.  If you go this route save your money and don't bother with the Rotax hose kit that they sell for about $60.  You can adapt your own with a couple pieces of hose you have at your shop.

    Jim the brakes are Airheart brakes. I have them on my Q-2 and they work well if mounted so they float properly.

  20. wypaul added a post in a topic Fuel Tank Coating   


    I used the Caswell sealer and would recommend it. I have not used fuel with alcohol but this stuff will stand up. The mix is critical so get one kit per tank. I used one kit for two tanks but the mix was a little off and it took several days to setup. I do have a ongoing test with 1 1/2 years of the epoxy soaking in Gasohol and it is holding up.

    I have been trying to get a hold of Brett myself to place an order for the Bush Gear, gave up and ordered them from Highwing LLC.

    I put an inspection ring in when I covered the fuselage. You can add one now and touch up the paint or another option is removing the horizontal stab. and fishing in a new longer bolt.

  24. wypaul added a post in a topic Bush gear   

    I am wondering about the Bush Gear, for those of you that have been using them for a while now, what do you think? Is this a great mod? Does the gear's wider stance make a big differance? Joey and any other users, what's the verdict? Anyone have Brett's cell number, I recall it being posted a while back but was unable to find it in a search.

    Hey Brian the level is checked at the third hinge rib which is the one closest to the strut attachment point on the wing. Also remember to level from side to side. Chapter seven in the build manual explains the complete process. There is an earlier manual(B model I think) on this site that you can download or I can scan that chapter and email it if you don't have the manual.
