    Default bolt size for towbar atachment KF2

    Am going to trailer a KF2 in a couple days & am trying to collect any parts we may need.
    Going to raise tail up & support it through the tube in frame designed for the tow bar.

    Anyone know ID of that tube & length of bolt required to pass through tube ?

    Thanks

    you probably know this already but just in case, the very back tube is the up pressure hole, the front of the 2 holes is down pressure, the hitch works like a filcrum, if i remember right on my model 2 it was a 3/8" tube so a 5/16" bolt, i dont remember the lengths

    My memory says the bolt should be 3 or 3 1/2" long, 5/16" diameter. Jim Chuk

    My model 4 fuselage is 4 inches wide at that tube. With the support brackets it takes a 6 inch long X 5/16 bolt. I got a longer bolt and cut off the threads then drilled the end of the shank to incert a pin to secure it.
