GTT70-EFI Drone Engine Product Description
The GTT70-EFI is a professional two-stroke electronic injection gasoline engine designed for RC enthusiasts. It has a compact structure, exquisite appearance, stable performance, and abundant power.
The newly designed fuel pump has self priming capability and adopts closed-loop pressure control to accurately control fuel pressure without returning to the fuel tank. It provides RS232 communication protocol and real-time acquisition of engine operation data.
The GTT70-EFI 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. 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.
GTT70-EFI is suitable for RC aircraft with takeoff weight of 10-15kg and fixed wing drones with equivalent takeoff weight. Equipped with NGH electronic injection system, it is suitable for fixed wing drones with takeoff weight of 10-15kg.
Provide two configuration options for electric start/non electric start.
