Hi
Thanks for you offer of help, I have bought 2 DoD's from ebay which both looked reasonable in the photos however, upon receiving the purchase,s one was quite knocked about with quite a bit of detail knocked off and in a box,this one is on MFA geared motors 2.5-1.
The second seems to be a lot better in the detail stakes and has never been on the water,and has MFA belt drive motors which are brand new but 1 of which has had the alloy motor pulley substituted for a brass gear pulley, but the main issue is the prop shafts have been fitted very poorly,instead of having the shaft exposed to the A bracket, the brass tube has been butted up to the A brkts instead.
So all in all I have some quite major work to complete.
However I have been very fortunate to obtain some back issues of Model Boats from 1994 that have a very detailed review and build of DoD. Many thanks for you offer of help
