Frank;
The new shaft was fixed in place with Araldite then packed with grease as so many others have done on here. The original Kort was retained, the prop was a Kort type, with maybe 1-2mm clearance (slack I know) as Mark so rightly said. 151 putty seems to be rather poor stuff compared to proper araldite (another lesson learned!)
For the battery I pair of Plywood U snapped pieces, both fixed to the hull with Araldite, to keep the battery in said frame I used a short but firm luggage strap.
Part of me is beginning to wonder if I should have had an additional U frame running along the keel as well as the two across the beam...
I agree she did go down fast, I am wondering if the battery slipped just enough to drop onto the poxy bungs?
If you do have any spare bits for the dickies, drop me a PM pretty please!
I admit I am rather taken with then.
Also, Frank, many thanks for taking the time to help me work out where I went wrong.
Mark;
Thank you
that coupled with Franks ideas and suggestions do point to the bungs failing in a truely spectacular way.
I will definitely plate over the inlets on the next one, along with using a decent filler such as Milliput
Thanks to both of you, I'm feeling a little more positive now about it.
