Question,


I have started a project and a question regarding Kardan's crossed my mind, in the picture I have drawn the motors at an angle (I think its 2 degrees from the horizontal - ignore that the kardan is going through the frame, as I have not removed the material for the slots yet).


Is it better to have the H bar between the heads or not,


Is it better to keep the drive train in line and angle the shaft and motor at the necessary angle, (I seem to remember this is the preferred arrangement)


Is it better to replace the Robbe Kardan with another supplier (its M4 ), the geared motors are Robbe as well (never used and bought many years ago for a project involving a Typhoon sub that never saw the light)

It's best to keep everything in line. Plenty of forum space already expended on this one.

So having read the thread on Huco V Kardan, I will have to assemble the full Kardan and use these, I also have to angle the drive line by 1 degree to ensure the motors do not foul the hull, in fact they appear to be just over 1 mm above the frame at that point and will allow for an engine room floor, it's packing out the difference at the front and rear that will be a challenge to get the motor into position (the centre line is 40 mm + above this new floor.


The vessel is about 62% drawn with the remaining 38% still to draw, this end is more difficult, building will be a nightmare, the wife unhelpfully suggested I complete the other 3 vessels first.

If there is still the option, then raising the shaft angle very slightly may give you bore flexibility at the inboard end whils making negligible diffrence at the propeller end.
