www.horizonhobby.com has ALL the r40 option parts in stock. better hurry!
well, we dragged two R40s tonite on a 200ft straight. my r40 with the OS TR Turbo was equal to fastharry's r40 with a 3 port RB turbo. i was running hpi fuel (prepping for the worlds) he was running blue thunder race formula.
bang for the buck i still love the os tr turbo.
now to run it against a 5 port rb and see
