I own a 66. If I had to do it all over again, I would have zero reservation getting a second one. To be upfront about everything I did have an issue with the fuel pump, it was replaced without question and over-nighted to me the day after Peter recieved my email. I had a second issue with the engine that resulted in a service call to the manufacture. I am not 100% sure what the issue was because of the language barrier. Something became miss-aligned and needed to be factory repaired. I had my engine back in less than 10 days, that includes a trip to Canada, then to Germany, Back to Canada, and finally to me...all at no cost.

Finally, I did have a temp sensor issue...the sensor WAS NOT defective. The issue was me and not properly calibrating the system.

Some of my problems were my fault as I was coming up on a learning curve. As my experience increases, my "problems" are decreasing. The engine runs flawlessly and makes a ton of power. I have over 3 hours on it now and have nothing but smooth sailing from the day I got it back from Germany.

Add to that outstanding customer service and support and I would give the 66 or any of the Behotec engine line. Peter at AltecareRC really took great care of me and he will be getting my business in the future.

That is my experience, I hope it helps.
