Looks good bryris. I may be off from the pick but the wheels look a tad small. If they are at least 3", then good job! If they are smaller than that you may want to change them out. Wheels smaller than 3" tend to try to push through the grass rather than ride on top of it. Creates losts of drag and makes it hared to take off. If your runway is paved, then they will be just fine.
