shanksow, it will not fly that good without the plastic half moon thrust tube that you can make out of any light plastic and c.a. it in place. then take the plane out and try to fly it. this mod took me 5 minutes to do with some plastic that I had in my work shop. If you look into the back of the plane all of that high velocity air after the fan is wasted in that big open aera. you have to cut this area down to the same size of the fan. I did put the cheater hole in the wing. This mod will not make it a speed demon, but it is lot better than the stock. go to Re: http://www.teamrcpilot.com/ and at bottom of the page will take you to see my mods. good luck [email protected]
