The question is not quite as the title says...
A while back (about a year now) i nearly tempted fait and brought a fast electric ARTR kit... needless to say it never happened in the end due to other commitments, and a few phobias with Li-pos'.
So in a change of mind recently... I decided to import the Delta Force 26" hull from offshore electrics...once its here i will do a build log on putting it together from a FE noob's point of view this is not a ARTR kit its being built from the hull up.
Now while i wait for it to arrive, i have a few questions that need answering as some of the answers i've heard are not really answers more along the line of statements of what i SHOULD do but no real explanation as to why it should be done like that.
So here's my first questions on surface drives.
Strut or stinger, which one and why?
Rudder Offset, i need to know why these are recommended over a 'in line strut rudder' (that's rudder directly behind the prop for other noobies), other then that 'in lines' cause drag, my arguing point with those is yes they may cause drag, but to what extent is is noticeable & if thats the case why do many single proped CATs run with with them and not have offsets, or is it down to personal choice, hull design?
Sizes of stingers, struts and rudders, what it a recommended length from transom of these drives? There are several available ranging from very short 40mm lengths, up to 150mm so what is recommended for the mid size boat and why?
All help is appreciated, but please explain your answers and not just make statements such as 'its like that cos it is' or 'that's 'the way I've always done it' as they really don't help me or others learn the reasons behind these item's and there uses.
Many Thanks RR
