He is using mine with the aluminum horn, but it's not that. I haven't had an issue with it when I run it in my TA05 and another guy borrowed it last week with no issues in his TC6.2. Plus it would not steer straight if it was the horn. But good call... Wait a minute.... Did I let him use my horn?? Hmmmmm hehe. Damn it I'll have to go look. hehe
