Parts in "Strong & Flexible" material to complete the model of the A61 Rmah in 1:200 scale:
To complete the model oft he Rmah Auxiliary, the following sets of 3D prints are needed:
- Rmah hull (in "Strong & Flexible") - this set
- Rmah superstructure (in "Strong & Flexible Polished")
- Rmah deck (in "Strong & Flexible Polished")
- Rmah details (in "Frosted Detail")
If you want to build a static model, all parts are included in the above sets of prints If you want to build the model as a functional radio controlled model, the following parts are available to complete the functions (further parts, e.g. the RC system, are needed):
- Rmah propulsion & steering (in "Strong & Flexible Polished")
- Rmah crane, radar & ramp (in "Strong & Flexible Polished")
To complete the boat as an radio controlled model, further components are needed. It requires the advanced skills and experience to complete this. For the drive, the following parts are needed:
- one 4 gram servo for steering (recommended: ES-07 by Modelcraft)
- two motors N20 (DC Ø 12mm x 15mm) for main propulsion
- two shafts of 150mm length (recommended: Graupner 409)
- two propellers of no more than 13mm diameter (recommended: Prop Shop STD/0550/4/LH/BR and STD/0550/4/RH/BR)
- coupling hose (recommended: Robbe R 1386)
- micro motor M700 (7x16mm) for bow thruster
- worm gear for bow thruster drive (M0,3, worm gear and 18 teeth gear for 1mm shaft, recommended Sol Expert S3 worm wheel and Z18031 gear)
The auxiliaries A61 Rmah and A62 Alfaq were built as multi-purpose vessels / auxiliaries fort he United Arab Emirates. They are designed as RoRo ships (roll on, roll off), but can also be used as minelayers and for other supply tasks. Some sources on the web also suspect a possible ASW (anti submarine warfare) duty that, however, has not been confirmed. Both were built by Nobiskrug shipyard in Germany in 2013.
The originals are 58m long, 11m wide, and have a draught of 2.4 meters. They are driven by twin screws (four blades each, no kort nozzles) and twin rudders. A bow thruster improves the general maneuverability.
Photos are available online e.g. here:
The model is designed in 1:200 scale. It is consequently set up to enable radio control functions (RC), both for the two shaft, the rudder and the bow thruster, which is designed to be fully working. Additionally, the radar, the main crane, the RoRo ramp a the stern and lights can be set up to work. However, this model is not set up to be ready to run, but it requires refinement and it only suitable for skilled model builder.
