Depends on the runway you use as to if those wheels are big enough. They seem to be fine for most runways I would say. I unfortunatly set my plane up for a horrible field, It is not regularly mowed and is extremly uneven. I tore a 1.5 in nose gear out once there when Ihit a rut. So I have 3.5 in the rear and 3 in the front. My plane looks silly like that fun cub but it flys from that rough field nicely now. If i had better tread my plane would look like a 4X4 plane lol. Remember to level the plane out with different size wheels fron to rear. You want to maqke sure the wing is hitting the air at the proper angle. The tape will help in keeping the hinge areas clean. I may be mistaken but basicly you will flex the hinge to say down then place the tape on the top side then reverse that for the other side.
