Vibration can be a real concern for a large-scale, single cylinder engine, but the DLE-85 keeps it in check with an included vibration-dampening engine mount. An extension on the exhaust minimizes the need to modify the cowl and and helps protects the engine and muffler in the event of a hard landing. The included ignition module can accept any input voltage in the range of 4.8 to 8.4 volts. Giant-scale pilots will appreciate the DLE-85’s impressive power and performance.
