Installation Tips:
Rudder, Tail- and Sailplanes

for 1/200 scale FBM sub



These upgrades mount into the tailcone halves (parts 95 & 96) of the Revell (or Revell/DE) Andrew Jackson kit (ex-Renwal Ethan Allen, Andrew Jackson etc.), which look like this:

Note the part, outwardly identical for left- and right sides, includes a heavy, fixed stabilzer for the horizontal tailplane, followed by a thick, wedge-shaped base, with a guide hole in it. And two thin (halves of) rudder posts, just forward of similar (half-) guide holes, both top an bottom.

Identically for each tailcone part, remove components as follows:

1- Remove the wedge-shaped base at left, carefully scoring, chiseling and/or sawing flush with the surface, taking care also to preserve the circular guide hole for the tailplane mounting shaft. Smooth/finish the newly exposed surface area, as this will be visible when the diving planes move.

2- Remove the heavy tailplane stabilzer - again, carefully scoring, chiseling and/or sawing flush with the surface - but DO NOT YET clean up the inside edges of the newly-opened hole (see Step 5).

3- Chop off both (half-) rudder posts, as indicated.

4- Test-fit the tailcone assembly, with tailplane upgrades inserted and connected by the linkage piece from the kit (part 100, not shown):

5- With tailplanes aligned (and level, when horizontal) test-fit each leading stabilizer upgrade, as shown (arrow). Its trailing edge should fit snug but not binding against the tailplane leading edge (hinge) - adjust/sculpt its boat-shaped "foot" and - only as necessary - carefully and very conservatively trim and bevel the inside of the cutout to produce the best fit, again taking care to preserve support around the shaft of the tailplane. Verify the stabilizer, when seated and butted as above, presents the top of its foot flush (or nearly so) with the tailcone, while extending to exactly the same length as its tailplane, and then secure in place.

6- Trim/grind the top of the stabilizer foot flush with the surrounding tailcone, and fill/surface any remaining gaps, as necessary for a seamless blend between the two.


The rudder upgrade replaces the single piece (part 101) of the Revell (or Revell/DE) Andrew Jackson kit (ex-Renwal Ethan Allen, Andrew Jackson etc.), as follows:

=> STATIC INSTALLATIONS (repositioned slightly more accurately): skip to Step 9<=
Note that (unlike the kit part, at left) the upgrade comprises a much larger top rudder, and smaller bottom one (right - not to scale), and that the connecting yoke of the kit is duplicated - to function identically with the tailplane linkage (part 100, not shown). If you are installing these upgrades to move as intended, ensure the inner surface of this yoke is completely smooth and free of any remaining casting wafer, pits or other defect(s). Fill any of the latter with the strongest/stiffest available filler - for which gap-filling superglue (cyano-acrylate) is recommended, as this area is subject to focused stresses.

7- Test-fit the tailcone assembly with the rudder upgrade in place, carefully adjusting the tailcone hole (as opposed to the rudder shaft junctions - again, due to high stresses), as needed to achieve proper alignment and motion.

8- Optionally as desired, further strengthen the rudder shafts (greatly) by removing and replacing them with lengths of brass rod or hardwood dowl, ect., installed where indicated (right), including firmly into the central yoke. (If you break a rudder, e-mail and Matt Stein Models will make it right!)

9- Optionally as desired for a more accurate - though non-moving - location of the rudder(s), cut one- or both of them free, fill the tailcone hole(s) as necessary and reposition per your references on the particular FBM sub-class.


The sailplanes upgrade replaces the stock sailplanes (identical parts 118) from the Revell (or Revell/DE) Andrew Jackson kit (ex-Renwal Ethan Allen, Andrew Jackson etc.), as follows:

Note each side of the kit sail includes a thick, wedge-shaped base (inaccurate) for each sailplane, containing a circular guide hole.

10- As shown at left, remove the wedge-shaped base, carefully scoring, chiseling and/or sawing flush with the surface, taking care also to preserve the guide hole, if mounting the upgrade planes in this same locaton - otherwise fill the hole. Smooth/finish the newly exposed surface area, as this will be visible when the sailplane moves.

11- Optionally as desired, insert a locator pin or central connecting shaft, provided by the builder, into the base of each sailplane, at the location of the punch-mark (arrow, at right) which is molded into each casting, for this purpose, and attach the planes.
