''The stern planes, bow planes, and rudders are all cast resin parts pulled from tools formed using the kit parts (modified to enlarge and lengthen their operating shafts and bearing pins) as masters. Now, I must make this absolutely clear: use of another parties commercial product to form parts sold by a second party (me, in this case) is both illegal and immoral if permission by the owner of that product has not granted clearance for such use. Mike Caswell secured that permission from the company front office.
NEVER pirate another man's work! Not even for your own private use ... too often such 'private' copies wind up finding their hands of 'friends'. You want to see kit manufactures and after-market outfits leave this hobby in the dust? Just keep stealing from them like this, and they will go away.
The three sets of control surfaces, rudders, stern planes, and bow planes made use of different type linkages to translate axial motion to torsional motion. The bow plane employed a traditional cast metal bell-crank that made up to its pushrod with a typical Z-bend. The stern plane employed a very thin-sectioned bell-crank that girdled the square sectioned stern plane operating shaft, it engaged its pushrod through a magnet-iron slug combination. There rudders were operated through a three-gear mechanism that translated axial motion to identical motion of the rudders.
Note that the stern plane and bow plane linkages, like their real-life counterparts, are arranged to work underneath their respective torpedo tube nest.''
