Pompebled.
I take your point, especially re experementing with cheaper plastic props, but, is there a direct comparison, plastic v brass ?
No one seems to state the pitch, only the diameter !
My thoughts on whether to silicone the rubbers to the metal adapters on the Robbe couplings was not because of any misalignment but purely due to the fact that the joint is quite sloppy,
not at all secure. I intended, (intend ), to use an industrial compound to, "Vulcanise", the parts together forming one completely flexible unit. This will satisfy my requirements for anti vibration and torque absorption.
The compound which I have used before to construct anti vibration engine mounts on 100cc model aircraft engines with great success is Sikaflex 292.
I am approaching the dreaded planking stage of the build, have posted a couple of photos of the stern or transom of the boat which seems to show a problem with the Amati kit.
The horizontal frame across the transom is definitely cut wrongly. Even after carving and sanding the dimensions don't add up.
Have a look at Sharkeys Aquarama build thread on RC Groups, pages 6 and 7 to see what I mean, poor chap really struggled.
