I was tentative as hell , first working on my Rocket , it all seemed daunting with the management systems and other people's horror story's ! If it broke then I would have to find a way to fix it , as couldn't afford dealer prices . Also I may mention I am compooter stupid . After buying a laptop and interface cable ,
@warp9.9 kindly had the patience to walk me through it , after getting the poor guy to explain it 3 times he put it in child language and ureeka . I got it !
I guess what I'm trying to say here is feast on the advice and experience offered by this community and you too would very soon be surprised how easy it is to do virtually anything mechanical on the rocket . It certainly enhances ownership and saves you a shed full of dollar !
