White Rose offers multiple models of tail wheels. Some models feature carbon fiber springs and others titanium springs. Within the two spring groups are three different spring dimensions. All tail wheels have identical yoke and wheel assemblies. The wheel, yoke, spring and steering arm are all included when you buy an assembly.
The longer carbon fiber and titanium tail wheels are 10.5 inches long and will lift the back of the fuselage 4 1/2 inches off the ground. The assembly weighs less then 3 ounces. The carbon fiber spring is 3/16 of an inch thick and 7/8 inches wide. The titanium wire is 1/4” in diameter. These tail wheels are intended for aircraft in the 35% to 45% size category.
The tail wheels with the shorter springs are 9 inches long and will lift the back of the fuselage 3 1/4 inches off the ground. The assembly weighs less then 3 ounces. The carbon fiber spring is 1/8 inch thick and 7/8 inches wide. These tail wheels are intended for aircraft in the 25% to the 30% size category. The extra large carbon fiber spring is 12” long and lifts the back of the fuselage 6” off the ground. It is thicker and stronger and aimed at the larger heavier 40 to 45% airplanes.
All tail wheels come ready to accept a steering arm (supplied) for those who like to use springs from the rudder horn or push rods. White Rose also drills a 1/16 hole through the yoke to accept a tiller arm or direct drive steering method. Pre-bent tiller arms are available. If you plan on using steering springs there is a great little kit that includes the springs, coated wire cables.
The standard tire is a softer compound similar to Du Bro. Also offered is an optional urethane spoked wheel that is molded directly onto the hub. This stuff is tough as nails and will take lots of abuse. Industrial conveyor systems, roller coaster wheels and skate boards all utilize urethane tires. The draw back to the urethane is the noise on hard surface runways but you will never wear it out.
White Rose is supplies tail wheels drilled through to accommodate an optional pivoting tiller arm. This solves the problem some had with breaking the tiller arm due to continuous bending stresses at the point where it attached to the yoke.
