    Default Anyone lengthen the stock pacer landing gear

    Has anyone lengthened the stock pacer landing gear.
    I'm not talking about the Trimmer gear or cub style gear .
    But the gear used on the 22/20 and pacer [Univair style gear]
    If so how much did you extend it and how did you do it?
    Any other modifications guys have done to the Univair style pacer gear ,I would like to hear about it.

    THANKS

    In my forum searching, this old thread came up, so because I too am interested in this modification I thought I’d bring it back to the top of the pile..
    so has anyone done this?

    Trying to extend a Pacer gear would be problematic. The attach fittings are only 12" apart, the longer you make the gear, the smaller the included angle at the bottom, and the more the landing loads would be for wheel spin up and braking. With such a short lever arm, I suspect you would need to install much larger tubing in the fuselage to absorb those loads!. In comparison, the PA-18 gear attach fittings are 21. 5" apart. Lengthening that gear will also reduce the included angle, but that angle is greater to start with.

    Thanks for that input sir, I guess the decision to make is either stick with the standard pacer gear or go with Trimmer’s design beefing up the lower fuselage and using Supercub gear. Just doing a Tailwheel conversion on a Colt experimental. I intend to fly it out of our ranch prairie airstrip but won’t be doing any sand bar operations or STOL comps

    Are you wanting more prop clearance? I think you are on the right track with the extended Super Cub gear. The streamline tube on the stock Pacer gear would be a weak point when extending. It is usually what fails on standard gear. One thing about the Pacer is with the shorter fuselage taller tires raise the nose higher. I bet 26" Goodyear tires gain you as much or more than 3" extended Super Cub gear with a lot less work.

    Well that’s exactly my thinking too, I intend to use either 8.50’s or the 26” tundras with a lot less invasive work on an otherwise damage free history on this colt frame (apart from the lower longeron corrosion that was professionally repaired) Any thoughts on Airframe Alaska’s T3 tailwheel setup?
