I'M FINALLY IN THE PROCESS OF BUILDING MY UCD46. MY QUESTION IS SIMPLE HOW DOES ONE INSTALL THE WHEEL PANTS,TWO #8 WASHERS AND THE WHEEL COLLAR IN SUCH A SMALL SPACE. DO YOU USE THE STOCK TIRES OR THINNER TIRES??MY PLANS ARE TO USE HI- TECH 475BB FOR ELEV'S AND RUDDER AND FUT 3003'S FOR AIL, AND A MAGNUM 80 FOR PWR AND A FUT-8U RADIO.
