I must say that I am a littlle disappointed in the performance, quality out of my new SUPERTIGRE 75. I am flying it in a 4* 60. Absolutely no verticle power whatsoever. The engine does not want to shut off when the carb is 100% closed.Also, while flying the other day, my plane started making a loud rattling sound. I hurried and landed to discover that a washer had come loose inside my muffler??? Cant fly without a muffler.
The RPM listed for this engine is 15,600. The most I can get out of it is 10,000. Supertigre says this is normal. I have'nt been flying r/c that long so maybe my expectations were just too high. Think I will just spend the extra money next time and go with OS.
Almost forgot, the glow plug was bad right out of the box too.
