John,
He has two of the standard thrusters for the stern (I gave him a new one a while back, and he got another second hand), and I have told him he could use a couple of washer pumps to give the bow manouverability (about £6 each), but like most of us like to do, he wanted to fit the original hardware.
I will let him cogitate a while longer and come up with the suggestion again. The choice has to be his.
I don't think it is the cost of the units themselves, they can be picked up occasionally fairly cheaply, but the cost of the little special extenders (if they are still available) that is sticking in his throat.
I suppose if I put my mind to it, I could make a couple for him. If Graupner can do it, I am sure I can come up with something.
Thanks anyway.
John
