The making and fitting of the deck, planking and cabin all followed established procedures and went smoothly. The only major challenge was the mast.
The picture of 2757 shows the last surviving RTTL (in original form) on display outside the R.A.F. museum near London. It illustrates the unusually complex mast. Ruminated long on how best to build it.
Had an unusual stroke of genius and made up a small wooden stand to the same dimensions as the base fittings of the mast. The developing mast structure could then be easily gyrated through various angles and dangles to gain access for soldering the main brass structure and fitting the styrene sections that make up the interstitial members.
This approach has the added attraction of making the mast as a single unit, which can be made readily detachable. Transport and storage become so much easier. The original mast could be collapsed, but the bracketry to do that looked difficult to reproduce successfully at small scale without machining resources.
To make the mast detachable, made up a clevis bracket under each mast leg on the cabin roof. The clevis mates with a hole at the end of the mast legs. Fitted a tapered pin into the clevis through the hole to hold the mast, along with a “keeper” bracket to ensure the pin remains in place.
The mast contains a radar scanner and the mast lights. To disconnect the wiring easily, fitted a servo style connector plug at the mast base. By disconnecting this plug and removing the pins the mast can be easily removed. Not quite as original, however, a good use of modelers “license”. The original wiring ran up the starboard mast leg, so copied it. My wiring is slightly more obvious, but is considerably simpler and much easier to service than passing it though a mast leg.
Decided to feed the electrical power to the superstructure by using springs on the hull mating with brass plates on the underside of the superstructure. The spring & plates conduct the current. Using this idea allows removal of the superstructure without disconnecting wires.
This works nicely on an installation with relatively few circuits. The main RC controlled on/off switch is the hull. The secondary circuits in the superstructure are controlled by small switches, so can select the radar and /or lights as desired.
