Hey guys my Name is Mike. I have had my UL1 for about 2 months and this video is my 3rd time taking it out. First time I took it out I dropped a prop off of the flex shaft and waited for the wind to pull it in. The 2nd time I had the Grin Racer 3 blade prop but couldn't get it too plane out possibly due to my 5000 ma batteries being placed right at the very front. I moved them back about 1/2 an inch and this is the result. BTW. I know it would rather turn left. As you can see in this Video.UL1 Superior Grim Racer prop upgrade. http://youtu.be/86DXl8xTln0
