Would that be my Old mate and partner in crime John Stevenson your refering to . ?

While I understand what your saying about " Mini and Rolls" I still don't agree.! . . . Problem is this game is not an exact science and every machine is different, even if the same Make and model using same parts.
Each machine will and does react different regards resonance, also the combination of this plus drives motors etc affects tuning and how the machine performs and it doesn't always go to plan. Which if compounded by poor components, poorly assembled and wired can lead to a very frustrating time.

You are lucky as you have I presume John helping and advising who is very experienced but others are not so lucky and they don't have the luxury to be able to turn to knowledable person when plan goes south.!! . . . I help lots of people in this exact situation and this lack of knowledge combined with poor components is the most common cause of there troubles and frustrations.
Yes often I get them working quick enough and using the parts they bought but often the machine is capable of so much more and limited by components or build quality.
Also often the poor quality electronic parts or one part in particular, Ie BOB's are the reason for there troubles and if they'd bought decent electronics in first place they'd have been working weeks or months sooner and still have all there hair.!!

I'm long in the tooth know at this game and IME there really is no substitute for quality electronics. They really do pay off in the end.
