Status: offline 		Hi, I have installed an ASP 91 2 stroke based on flyers comments about weak performance with a 60 size engine. Has any one increased the fuel tank size to match? If not, what kind of flying time can I expect with the original tank??

Status: offline 		I was having trouble getting reliable runs with the ASP so I ordered an OS 95 AX. When it came in and I went to install the OS, I discovered that the muffler bolts had come loose which would explain the poor running. I installed the OS since I had it and it runs very strong. I set the timer during my first flights for 5 minutes and had over a 1/2 tank of fuel left. I upped the time and still had lots of fuel after a 8 1/2 minute run. I think that I can get a full 10 minute run but not sure yet. I have video segments of the plane which I will post if I can edit them to look reasonable.
