Re: Scale Models - Aircraft, Battle Tanks & Ships
Things like sand paper or hobby knife can be purchased locally but everything else needs import. Airbrush- artmaster is an Indian brand that is good for broad works but detail jobs are best done with precision airbrushes and they need to be imported- infact I recently lost 9k on a gun after it got lost in custom due to covid related disruption :/
Covid has caused major issues in my supply chain.

1:72 Convair F-102 Delta Dagger 0-61409(56-1409), 156th Fighter Interceptor Squadron, Florida Air National Guard, United States Air Force (Hobbymaster)
The Convair F-102 Delta Dagger was designed to be an interceptor aircraft and act as the core of USAF air defenses in the late 1950s. The F-102 first appeared in service in 1956 with the task to intercept Soviet bombers. The official name for the F-102 was “Delta Dagger” but the most common term used was “Deuce”.
A member of the Century Series( F-100, 101, 102, 104, 105, 106 & 111), the F-102 was the USAF's first operational supersonic interceptor and delta-wing fighter. It used an internal weapons bay to carry both guided air to air missiles and rockets( FFAR - Fin Folding Aerial Rockets).
The prototype YF-102 made its first flight on 23 October 1953, at Edwards AFB, but was lost in an accident nine days later. The second aircraft flew on 11 January 1954, with a dismal performance. Transonic drag was much higher than expected, and the aircraft was limited to Mach 0.98 (i.e. subsonic), with a ceiling of 48,000 ft (14,630 m), far below the requirements.
To solve the problem and save the F-102, Convair embarked on a major redesign, incorporating the recently discovered area rule, while at the same time simplifying production and maintenance. The redesign entailed lengthening the fuselage by 11 ft (3.35 m), being "pinched" at the midsection (dubbed the "Coke Bottle configuration"), with two large fairings on either side of the engine nozzle, with revised intakes and a new, narrower canopy. A more powerful model of the J57 was fitted, and the aircraft structure was lightened.
The Original YF-102 with its straight sided fuselage:
The re-designed YF-102A with pinched fuselage, narrower canopy and redesigned intakes:
The first revised aircraft, designated YF-102A flew on 20 December 1954, 118 days after the redesign started, exceeding Mach 1 the next day. The revised design demonstrated a speed of Mach 1.22 and a ceiling of 53,000 ft (16,154 m). These improvements were sufficient for the Air Force to allow production of the F-102, with a new production contract signed in March 1954
The production F-102A had the Hughes MC-3 fire control system, later upgraded in service to the MG-10. It had a three-segment internal weapons bay under the fuselage for air-to-air missiles.
Armament consisted of six Hughes GAR-1D Falcon radar-homing, or GAR-2 Falcon infrared-seeking, air-to-air guided missiles, or a combination of both, carried in two internal bays. (The Falcon missiles were re-designated AIM-4A and AIM-4B in 1962.) The missile bay doors contained launch tubes for twenty-four 2.75-inch (70 millimeter) unguided Folding Fin Aerial Rockets (FFAR). The Delta Dagger was not armed with a gun.

The F-102 was later upgraded to allow the carrying of up to two GAR-11/AIM-26 Nuclear Falcon missiles in the center bay. The larger size of this weapon required redesigned center bay doors with no rocket tubes. Plans were considered to fit the MB-1 Genie nuclear rocket to the design, but although a Genie was test fired from a YF-102A in May 1956, it was never adopted.
So, how do you try and escape after firing an air to air nuclear missile at a formation of high flying Soviet bombers? Here's the answer. Could it have worked for the escaping F-102 pilot( F-106 in the illustration)? Well, let us just be glad that we never had to find out.
The F-102 received several major modifications during its operational lifetime, with most airframes being retrofitted with infrared search/tracking systems, radar warning receivers, transponders, backup artificial horizons, and improvements to the fire control system. A proposed close-support version (never built) would have incorporated, in addition, an internal Gatling gun, an extra two hardpoints for bombs (in addition to the two underwing pylons for drop tanks that were fitted to all production F-102s), bigger internal fuel tanks, and an in-flight-refueling probe.
There were 889 F-102As manufactured when production ended in September 1958.
The F-102 served in the Vietnam War(painted in South East Asia camo), flying fighter patrols and serving as bomber escorts. A total of 14 aircraft were lost in Vietnam: one to air-to-air combat (to a VPAF MiG-21 using a K-13 missile), several to ground fire and the remainder to accidents. The F-102 was employed in the air-to-ground role with limited success, although neither the aircraft nor the training for its pilots were designed for that role. The F-102 was equipped with 24 2.75 in (70 mm) FFARs in the fuselage bay doors. These could be used to good effect against various types of North Vietnamese targets in daylight but the NVA AAA was a big threat. At night it proved less dangerous to use heat-seeking Falcon missiles in conjunction with the F-102's nose-mounted IRST (Infrared Search & Track) on night time harassment raids along the Ho Chi Minh trail.
The F-102 and TF-102 trainer were exported overseas to both Turkey and Greece. The Turkish F-102s saw combat missions during the 1974 Turkish invasion of Cyprus. There have been claims of air combat between Greek F-5s and Turkish F-102s above the Aegean Sea during the Turkish invasion. A Greek internet website editor, Demetrius Stergiou, claims that the Greek F-5s had shot down two Turkish F-102s, while the Turkish side has claimed that their F-102s had shot down two Greek F-5s; however, both Greece and Turkey still officially deny any aircraft losses. The F-102 was finally retired from both of those air forces in 1979.
The F-102 left U.S. service in 1976, while the last QF-102A / PQM-102B drone was expended in 1986. No F-102s remain in flyable condition today, although many can be seen at museums or as permanent static displays as gate guardians at Air Force and Air National Guard installations.
