ASP Super 52 update....
 

I am trying a new ASP Super Series 52 in a Tiger 2. Ran 3 tanks though it before it was barely reliable. Found out that I needed to run ""very rich" in order to prevent deadsticks during a flight. The engine looks like an OS engine clone, but it is very different. is Now after about 10 more tanks of flight time, I finally started leaning the needle valve. The engine runs very reliable and the power is coming on strong. I am getting over 15K on an APC prop! I am beginning to have a lot of respect for this engine! It just took a long time to break in I guess. Later, Fast!:D
