To do it rite you need a large 40%TOC airplane that was built strate and true by a profesional custom builder.You must make sure that you have taken hours to perfect your setup to be geometricly corect. You must make sure you spend the time to program and mach all your didgital sevoes in perfect sincronisation so that there is no BINDING!Make sure you have redundancy on your baterys,recivers,and switches.Also some KS tuned pipes are mandatory to get that extra edge on power. When all of this is done, your plane is balaced and moter is runing like a top fuel dragster you are all ready for the madin flighit !!!!Now you aproach the flight line knowing you have done your home work and spent countless dolars and hours on constructing a TOC comitition plane and you cant help but think about the 2000 pionts of failure as every one is comenting on the craftsmenship of it!!After your plane is all trimed out ,You must make sure what you are going to do is pemeditated befor you do it.Remember It always leaves a good impreshion to do this in the midst of a power manuver like in the botom of a knife edge loop :tip ,its more impressive at full throtle and make sure your moter is under proped to get maximum prop rip and make shure smoke is on!!Now ,make sure that the point of impact is at the botom of the knife edge loop and is centered directly over a paved runway.When done in this fashion with great precision it can leave quite an impression!!![sm=thumbup.gif]
