Experience is little. I might have been wrong on the TRX thing. I think TRX is a engine model? The truck is a Traxxas T-Maxx 2.5 not 2.5r the original 2.5. Tell ya what How about a picture of it. That way you all can see what it is and I don't have to try to explain things I'm not really sure of. I attached 3 pictures. Hope they work.

Thanks again
