Hi, I'm pleased to display my latest model. New Holland LS150 Superboom Skidsteer Loader. Uses 2 x XL motors for drive 2 x M motors for lift and tip Lift is by worm drive gear box to gear racks inside the cab Tip is by a driveshaft powered by the rear M motor. This shaft runs up the boom to a worm gear just in front of the cab. Battery box fits perfectly inside cab and helps to maintain traction on front of machine. This model has all the power of the bulldozer, maybe even too much power! Can be jerky at start of each movement, due to no speed control on transmitter remote. This was not difficult to build. Very basic gear train. On the whole, I am very pleased with the results. Comments to: mtomb@tesco.net
