Description
LR4 Plus 4-inch long range frame
The LR4 Plus is a 4-inch carbon fibre frame designed for light long range. It has a 177 mm wheelbase and weighs 54.3 g, with 3.5 mm arms and 1.5 mm for the other parts. With 4-inch props and 1505 motors it flies a long time on little power.
It has two towers: the front one takes 16 × 16, 20 × 20 and 25.5 × 25.5 mm flight controllers and the rear one, 20 × 20 mm, holds the video transmitter. That keeps the flight controller apart from the video and cuts interference.
