The wheel are Matco wheel. I don't remember the
number for sure (I think the mains are F509), but if you tell the Matco
rep. what you're looking for, he's gonna identify the wheel for you.
I wanted 15X6.00X6 tires on my plane so I have a bit more versatility
in terms of terrain I will use.
Here is nose gear installation. Initially, I could not get proper
deflection (18 degrees), but not because of the usual reason. Most
builders have that problem because the rear stops are not far enough.
In my case, I do not have this problem as I mounted the gear 1/8"
more in front than the plans specify to accomodate a 1280 bungee. My
problem was that the welds on the vertical bolts were interfering with the
guides. I ground a radius to resolve the problem.
One evening, I was reviewing the AC43-13 manual, not being sure that I
used the proper bolts on the landing gear boxes (they were showing 4
threads with two washers). I decided to replace all bolts with
shorter ones that now fit well with a single washer.
