READ THE NOTES/UPDATES SECTION BELOW BEFORE DOWNLOADING THIS!!!
Even if you do not wish to install landing gear right away you can still mount the front skid and install the blank plate which performs exactly the same as MarkQ's original front skid. Then when you are ready for landing gear you can easily slide the servo/wheel mount into the slot, plug in the servo and bolt on the rear gear and go. Takes less than 3 minutes to convert from skids to wheels!

I am not specifying the control linkage since there are so many options for this. You probably already have something that will work laying around.
FRONT:
The black control arm that comes with the front gear linked above will get the length cut down past the slot and you will need to drill a hole for the servo linkage. (I am working on a new design that will make this easier and not require the steel collar, check back and read the notes section for further details.)
REAR:
There's 2 choices for attaching the rear gear to the belly mount. In my case I used the hexagon nut mount with hexagon nuts with .360" flat to flat (23/64" wrench size).
OR
Choose the drill (#7/.201") and tap (1/4-20) version. DO NOT GO ANY BIGGER, remember this is not a solid piece! (another reason to have at least 4 vertical shells!)
In both cases, USE NYLON SCREWS to hold gear to belly mount! This will allow them to break in a severe landing rather than ripping the gear off the plane!
You will need to drill 2 new holes slightly larger than your nylon screws, and 2.75" apart on your aluminum gear (1.375" from center) See notes below if your screw heads head the curved part of the gear
Gluing pieces to fuselage:
Once you have everything fitted and are satisfied, use either E6000, or Uhu Por to glue the front skid and rear belly mounts into place. Once this is done you may then cut the foam out to fit the servo for the front gear. If you choose to make the front gear permanent I suggest you also glue the servo house to the foam to help strengthen this area and prevent tear out on a rough landing.
Note: I changed out the wheels that came with my gear for larger wheels since I use a grass runway.
Please let me know if I missed anything... There is a lot going on to remember!
