Yep - can't beat the reliability and user friendliness of the OS32SXH with a good tuned muffler

If you are using muffler pressure be sure that no fuel is at any time is transfering from your fuel tank through the pipes pressure nipple into the tuned pipe. This raw fuel will be immediately drawn into the cyclinder and flodd the engine everytime you turn the engine over and the exhaust port is exposed. This syphoming will happen anytime you hold the heli in a position where the tanks center line is above the pressure line nipple (while transporting the heli, carrying to pit area, or at any time while holding the heli).
