I gave it its first run today.
It did not sink so that is good !!
It sits very low in the water, but that is normal to me from my full scale hydro days as a safety diver.
If I hit full power it appears to pop up out of the hole easily.
If I try to slowly accelerate then it want s to do a submarine impersonation. O.k so full power from idle is the go then !!

I set it up to run with the tail-shaft angled a little down to produce lift on the rear. I suspect that this had the effect of not letting the prop run up to full rpm.

I have now set the tail shaft at 0 deg (flat) and will try that in the morning. It is very wet here right now and I hope that the weather will clear so that I can get a few runs in the morning before the sail boats turn up, they seem to have some sort of “ownership” of the pond. [&o]

Btw my hand made water cool system works, a nice trickle of water out the side shows that there is flow…………..cool !!
