All the horror stories aside, I have a Maloney 100 on a 1/6 scale WACO and have been very pleased with it. The plane is a bit overpowered (that's the way I like it). The engine starts with a starter without any problems and runs like a clock. Never had an engine failure just smooth reliable runs. Besides the function, I think it is one of the best looking engines ever made of this type and I also like the innovative muffler and choke design.
