Help! Skyline not working right

[SkylineGT-R_man]

My Skyline isn't working right at all. It works good when I have the controller right next to it. When it goes maybe three to four feet away, it starts to stutter. Like this ...!...!...!(the ! means it gets a little bit of power). when it goes a little farther yet, the power completely cuts out. This is my second Skyline, the first did the same exact thing. When the second would work long range, it would get smoked by my friend's less invested and less powerful Supra. All the mods I have done to it are: Stage 1 & 2, suspension & steering, tires, metal bearing kit, and rechargable batteries. My friend's Supra doesn't have Stage 1, metal bearings, and sus. & st. Their are rumors on the recall on all Skylines, is this true? If it is will they take mine back and give me a new revised Skyline even though mine has some "battle scars"? Or, will they just give me a different Xmod? If so, will they take my body kit and Skyline starter kit without a receipt? If anybody that reads this thread that has information, please e-mail me any info. Thanks.
