NGH GTT70-E Horizontally-opposed twin-cylinder 2-strokr gasoline engine

NGH is famous for producing high-quality gasoline engines, and the GTT70-E is a professional two-stroke gasoline engine designed by NGH engineers for RC enthusiasts. It has a compact structure, exquisite appearance, stable performance, and abundant power.

The GTT70-E engine is a horizontally opposed dual cylinder engine derived from the GT35 engine, equipped with radial mounting seats, and RCXEL's customized automatic angle capacitor discharge dual cylinder synchronous ignition system for NGH. Precision forged connecting rod with needle roller bearings, equipped with three high-quality deep groove ball bearings on the crankshaft; The cylinder liner is made of wear-resistant ductile iron, and the roundness tolerance of the inner hole in the cylinder body is within 0.01mm, which is much higher than the roundness tolerance of the inner hole in the aluminum alloy chromium plated cylinder liner, which is 0.03mm. In principle, the aluminum alloy chromium plated cylinder liner does not meet the environmental protection requirements of the European Union; Equipped with 2 integral welded exhaust pipes as standard, it effectively improves and reduces noise, and is highly praised by RC enthusiasts.

The GTT70-E is suitable for RC aircraft with takeoff weight of 10-15kg and fixed wing unmanned aerial vehicles with equivalent takeoff weight. Equipped with an NGH electric starting device, it is suitable for vertical unmanned aerial vehicles with takeoff weight of 10-15kg.
