In between 2006 to 2008 we built a fully functional radio controlled scale model of a Russian submarine Project 971, Bars class, the NATO classification code "Akula". This, and other, fabulous submarine models are produced by Alexander Engle KG. In our opinion Akula is visually the most appealing design of a modern multipurpose submarine of the Cold War era. Details about our RC model construction can be found in this article. Model has fully functional forward and reverse run, dive and emerge function plus periscope depth run (what is in submarine models the most desired regime – with model just under water level and periscopes peaking above). Further it has functional rudders with automatic leveling and operational position lights. This submarine model can dive approximately 1 meter deep and she still emerges afterward ;-)

Wooden static scale models of the ships: Santa Maria, Golden Hind, Havets Vinthund and Vasa. Built from IGRA kits made in Czecho-Slovakia in 80's.

The ADORE static paper model in scale 1:200 of the biggest ever built submarine - the Russian Navy nuclear ballistic missile submarine Project 941 "Akula" (Shark) class, NATO designation Typhoon. Length 175m, beam 23m, draught 12m, height 28m, submerged 48,000 tons, speed submerged 27 knots (50 km/h), endurance 120 days submerged, test depth 400m, crew 160, propulsion 2 × OK-650 nuclear reactors 190MW (254.800hp) each. Seven ships built, 3 are still in service (Dmitriy Donskoy, Arkhangelsk, Severstal). Armament: 20 × RSM-52 SLBMs (range 8,300km), 4 × 533mm torpedo tubes (type 65K torpedoes or RPK-7 Vodopad missiles), 2 × 650mm torpedo tubes (type 53 or RPK-2 Viyuga), 1 × Igla SAM.

Plastic model of Schnellboot ("S-boot" or "E-boat", "Torpedo Boat", "Enemy Boat") in 1:72 scale - the German torpedo boat from World War II. Plastic Airfix kit was equiped with RC elements (functional motor, rudders and position lights). The fastest boat of its era. A short video documenting the funcionality of the rudders is in this link. And a 90 seconds long video demonstrating seacapability of Schnellboot's model is in this link (20MB).

An eight-channel transmitter Robbe/Futaba FX-18 working at frequency FM 40MHz, channel 56, crystal 40,735. Transmitter is expanded with Robbe/Futaba FX Multi-Switch-Prop for another eight channels. The frequency 40MHz is by General Authorization of Telecommunication Authority dedicated for all types of RC models. It is preferrable for models of RC submarines which require good underwater penetration of RC signal.

In Akula is installed an 8-channel receiver Robbe/Futaba FP-R 138DF 40MHz FM. Receiver is accompanied by decoder Robbe/Futaba Multi-Switch-Prop 12+2 for eight more channels.

In Schnellboot is installed smaller sized 8-channel receiver MZK Octava 40Mhz FM.

Our fastest model building so far is the Hummer M1025 a 1:12 scale RC model from Tamiya (#58154) with all 4 wheels drive. We built it in four days as this enjoyable set contained almost all one need for building. We opted for the only purpose this vehicles should have had – the Red Cross Disaster Relief. The original Hummer H1 was a specially equipped disaster communications vehicle donated to the American Red Cross by the manufacturer of those cars the AM General. Our model is a “what if” of a car in the Slovak Red Cross service (Slovenský Červený kríž). A little modification of the kit was a use of a multi purpose light unit for cars from Modelcraft and an addition of the wind-shield wipers.

Our first aeroplane display model is from Eduard plastic kit in 1:32 scale with an additional "Big Sin Set" of the Messerschmitt Bf 109 E-1 fighter. It was one of the first modern small interceptors designed in mid-1930s which later became a workhorse of the WWII as it was produced in very high numbers. This Bf 109 E-1 is our interpretation of the 13th fictional aircraft of the Squadron 13 of the Slovak Air Force - one of the smallest aviation units regarding quantity of owned aeroplanes in WW2, but nevertheless with a quite high number of 215 confirmed victories (16 unconfirmed) during their short operational period on the East-front from October 1942 to November 1943.

King Hualer is a RC semi-scale kit from Tamiya No. 56301 of a US truck in 1/14 scale. Each axle is supported by a realistic ladder frame chassis and paired with front and rear metal leaf springs and coil spring dampers. The front-mounted motor provides power to four rear wheels via propeller shaft, mirroring the system used on actual road-going trucks, and utilizes a 3-speed transmission. The Multi-Function Control Unit (MFC-01) adds lights, sounds and vibrations. We enhances this model with a smoke emitting unit.

Our interpretation of the Revell plastic model of Spitfire Mk.II "Aces High" in scale 1:32 with the faithful decals for the Aces High song version as featured on the legendary 1984 Iron Maiden album Powerslave. Added photo-etched parts sets of the interior, seatbelts and landing flaps from Eduard. Painted with an unusual “Night and White” bi-colour camouflage on the fuselages and wings under surfaces.

Bell P-39D Airacobra in 1:32 scale from Revell plastic kit - the principal fighter of USAAC entering WWII. Interestingly 5578 P-39s, half of production, were used by Soviet Air Force in East European front. This P-39D belonged to 8th Fighter Group in 1942 stationed in Milne Bay, New Guinea. The first fighter fitted with a tricycle undercarriage. Innovative design from 1937, with GM Allison V-1710 liquid cooled V-12 piston engine behind the pilot, fitting central Oldsmobile T-9 37mm calibre cannon. Carried also 4 Browning M2 12.7mm machine guns in nose and wings with additional 2 of 7.62mm. Bell Aircraft company decided to leave-out advanced turbo-supercharger (installing outdated single-stage, single-speed), which later prevented P-39 from performing in high altitudes. This model also features 227kg fuel drop tank as no space was left in the fuselage for a fuel tank. The standard fuel load was therefore carried in wings, resulting that the P-39 was limited to short-range tactical strikes in a low to medium altitudes. Model was built during 2017.

This Ford F-350 High Lift model from Tamiya (#58372) in 1:10 scale with a Pick-up Truck MFC-02 (lights, sounds, vibration) is our second RC car which we build in 3 days (plus modifications over time).
The MFC-02 is also an electronic speed controller, therefore a separate ESC is not required. To control this RC model we bought a 6 channel Carson 2,4 GHz Reflex Stick 2 transmitter with a receiver. As the MFC-02 needs only 4 channels the remaining 2 are not used for now. We also got 2 servos Carson CS-6 and 100 ml Tamiya spray paints TS-17 Gloss aluminium and 2 cans of TS-19 Metallic blue (note that the instructions recommends TS-51 Racing blue and TS-75 Champagne gold). Black plastic parts are painted with 23 ml acrylic X-18 Semi gloss black. Final coat was done by Tamiya spray paint TS-13 Clear.
Since we have now more batteries to charge, we got a charger YES I-Peak 665 allowing us to charge batteries within 1-2 hours instead of a whole night (with the simple charger we used so far). And, since there is more fun with always available full batteries, we soon got also SkyRC RS-16 charger with 16A eFuel power supply. This power source can run both the RS-16 and YES I-Peak 665 simultaneously at 5A. And for the trips far away from home, we also got CARSON 4A Quick-Charger.

On a request of our son, as he became a fan of Transformers’ BumbleBee, we have re-painted the F-350 to BumbleBee’s yellow-black color scheme in 2018.

A Wingnut Wings 1/32 model of, often overshadowed by its more famous Fokker or Albatros Great War competitors, Pfalz D.IIIa airplane. For us it is one of the most elegant WW1 fighters. As so many of the contemporary aircrafts were heavily personalized. For this anti-camouflage is responsible pilot named Max Holtzem of Jasta 16b group, who perhaps surprisingly, later become a flight inspector on the P-51 Mustangs assembly line during WW2 in America.

In summer of 2014, we finished the plastic Wingnut Wings model in 1:32 scale of an Albatros D.V WWI fighter, as it subjectively seems to be one of the best looking Albatros Flugzeugwerke GmbH designs of the Great War. Its single spar lower wing allowed greater visibility for the pilots but was also the cause of numerous and fatal accidents. Despite this, it was manufactured in greater numbers than any other previous German flying war machine (only surpassed later by the Fokker D.VII). We chose an early color scheme of Eduard Ritter von Schleich (total 35 victories) as a remembrance of his famous “up-nose” pose photo beside his Albatros with the Bavarian lion as his personal marking. Interestingly, when his best friend Leutnant Erich Limpert was killed in a dogfight, Schleich ordered his plane to be painted all black. These black planes soon led to Schleich being dubbed 'The Black Knight'. Demobilized in late 1921, Schleich worked as a peat farmer, and later as a Lufthansa airline pilot. Later, sadly, he joined the Nazi Party in 1931, and at the same time became a member of the SS-Fliegerstaffel, a paramilitary flying organization. He was given control of the Hitler Youth flying programmes, and promoted to General. With the creation of the Luftwaffe in 1935, Schleich returned to military service as a Major overseeing the training of “air reserve” units and of dive-bombing pilots. After the war captured by British forces died in custody in 1947, aged 59 years.
