    Gotta love the thread tape and multi pliers on the fuel pump! Sooo much fun to be had with a plane like that

  2. Dusty added a post in a topic Strip it the rest of the way down?   

    I was hoping  a few would chime in on this one as I have wondered the same! My 1.5 mm screen is due for replacement,the support won't be going in unless there is a flutter issue.

  3. Dusty added a post in a topic 912 install on KF4 prep/planning/pictures/advice   

    The latest tanks are too tall to fit without shortening, I had to reuse my old tank which doesn't appear to be modified. I guess rotax may have enlarged these tanks for extra capacity?

  4. Dusty added a post in a topic Facet fuel pump   

    I use a facet 4 psi pump. It is turned on before startup to test its pressure. Start is with it off to check the mechanical pump pressure. Takeoff and landings the electric pump is on. The pressure with both running is 5.2 pound,I also have a bypass on both pumps with a one way valve so if one pump blocks it is bypassed by the other. I currently have a problem with my facet as with the bypass clamped off I have severely restricted fuel flow,these pumps can give problems. My first aftermarket facet lookalike pump failed internally and wouldn't make more than 1 pound pressure .Yes I am paranoid about fuel flow but have witnessed an early 912 pump fail resulting in a forced landing. The 582 pumps appear to be nearly bulletproof with only the pulse line giving  problems. So for me the jury is out on this one!

    That has solved a mystery for me as my fox 3 needed long arms to get the elevator to full travel.
    thanks.

  6. Dusty added a post in a topic Done getting bit in the ASS by toe brakes   

    Sorry to see your bird bent, yes the std brake setup isn't the best. My fox 3 had a similar setup so I adjusted the brake peddles forward ( toward the bulkhead) as much as possible. The later 4,s have a better setup, whether this is practical to retrofit a similar system so the "active" brake becomes more effective when the rudder is being used.

  7. Dusty added a post in a topic convert fr 582 to 670   

    The 670 combustion chamber is quite different to the 582 but for simplicity reasons and dual plugs the 582 head is used,although not ideal there are plenty flying in this configuration. I believe if the 670 is bored more than 20 eversize the 582 head needs machining. Rotax Rick was experimenting with a dual plug modified 670 head,best give him a call. I never got to finish my 670 for my fox 3 but the chap who purchased her is committed to finishing what I started, so any feedback from others will be appreciated and passed on.
    cheers

  10. Dusty added a post in a topic 2 stroke piston options??   

    I fitted with SPT ceramic top Pistons with Teflon skirt coating.definatly more power.400+ hours  with no problem,just don't use the supplied caged bearing. A complete kit including gaskets was about the price of a single rotax piston. Also don't use the single ring piston option. eBay.

    Ivo prop motor
    Has anyone experimented with different motors? I have fitted the high pitch blades to suit my new gearbox ratio but can't depitch enough without the original 25 year old motor stalling. I could order from ivo who are great to deal with but due to my location there is a two week delay . I am looking at a 540 size 32 turn motor locally,this is a high torque motor that looks to be a direct replacement.
    any thoughts or experience on this subject?

    If you go down the road of using the icom internal intercom you will be pleasantly surprised. It is a great intercom.

    A word of caution on using egt for carb balancing. These gauges are not generally accurate enough. Swapping the probe position front to back we'll give an idea of how matched they are. They may be close, but you need to be sure.

    A garden weed sprayer (the type with a flexible hose )is the perfect cheap solution for bleeding brakes.

  18. Dusty added a post in a topic Need help   

    If your C of G allows,I would reccomend replacing the single spring with multiple springs as springs do break. A single will leave you stranded where a multiple will only sag. As an aside there has been a few discussions on maule v's Matco tail wheels !

  19. Dusty added a post in a topic First Flight   

    Fly. Or don't fly,the area in between isn't a place for newbies. However, time spent taxiing at a brisk walking pace is invaluable as it lets a pilot get a 3 point sight picture firmly ingrained,and is good practice for getting more comfortable with the machine.I find the tapered cowl on a kitfox is one thing that really throws first time KF pilots,A small felt pen mark on the windscreen is a good aid for setting up a true approach.check whether  it is also legal to taxi an aircraft,as taxiing here is classed as p.i.c so needs to be authorised by a suitable instructor.

    Kitfox 3 & 4 are different as the 4 has more rake angle at the cowl,but would serve as a good guide

  21. Dusty added a post in a topic Starting my Homemade Hackman   

    Don't panic yet Vance,my setup needed multiple turns initially.the restricter orifice to the air cleaner has a huge impact on sensitivity,as already stated ,start big and work back to a smaller reference orifice.now up to 10.000 ft is covered in just less than one turn.

  22. Dusty added a post in a topic Engine   

    Rotax have put a lot of thought into their oil injection system (ever noticed the little casting bump in the intake!)it works real well.  We had an issue with one of the club planes with premature wear,the oil injection was immediately blamed. The crank was replaced and This time the oil setup was checked,yup 100:1 AVEREGE oil mix!!!! . PLEASE all 582 owners check the oil is being delivered in the correct quantity (70:1 is good) these engines are incredibly reliable if set up and treated well.

    I may be wrong but try a 582 vent nipple from the head? It was awhile ago.

    The jet size definatly needs to raised up from standard.
    If on the test flight the EGT's start to get too high be prepared to ride the choke a little the keep the temps under control.
