I had a Tower Hobbies .46 and it ran like a champ. Remarkably powerful and it fly my Kaos .40 with authority in its factory state. I wouldn't hesitate to buy another one. There was some RCM article published some years ago that ranked the engines (the .46 and .61) pretty high on performance and quality. It's what convinced me to give them a go and hadn't regretted my decision ever since.

But like most engines, if you take care of them and tune them right, they will last a long time. Neglect them and it will be a short lived experience. The OS engines seem to handle neglect better with their added quality engineering.

i know my engines and take care of them and that's why they last as long as they do... Hobby money is tight these days, so the extra effort helps stretch my limited dollars..
