David Andersen, has been a scale aircraft enthusiast/ designer for a few decades.  His adaptive technical research make him a precise but humble line judge at many Scale R/C Contests.

Those of us privileged to know and interact with him have learned that his scale passion is infectious and provides insights as to what "Scale Aircraft Modeling Really Means".

Kawasaki Ki-45 "Nick"

Ki-45 RCU Build Thread

David's latest offering is an Exact 1/5th Scale Kawasaki Ki-45 Toryu.  Suitable for R/C competition, a museum static display and/or everyday enjoyment at your R/C flying field!  A variety of unique Scale Paint Schemes were documented that allows you to build a one of a kind aircraft for yourself!

In December 1937 the Imperial Japanese Army Air Force issued a requirement for a two-seat, twin engine heavy fighter.  A design team headed by Tako Doi went to work and came up with an aircraft not dissimilar to the Messerschmitt Bf 110 ... the Kawasaki Ki-15 Toryu.  The word Toryu means "Dragon Killer", which was the purpose of this aircraft who's specific design was intended to be a superior night fighter for Japan's home defense against US bombers.

David's 1/5th Scale design is an excellent flyer with stable flight and landing characteristics.  The aircraft can be powered by two 50cc gas motors but a few flyers are building theirs with equivalent electric motors.   Flight Video

Brief History

The first Kawasaki Ki-45 Toryu (dragon killer/slayer) prototype flew in 1939, a cantilever mid-wing monoplane with retractable tailwheel landing gear.  A slender fuselage provided enclosed accommodation for two in tandem. 

Design Specifications

120" wingspan, 1676 sq. in., 86" Length, 40cc to 50cc Engine,  built-up balsa & ply, prototype weight: 45Lbs, 7 plan sheets.

Problems followed with the engine installation, and it was not until September 1941 that the Ki-45 KAIa entered production.  Armament of this initial series version comprised one forward-firing 20mm cannon, two 12.7mm machine-guns in the nose, and a 7.92mm machine-gun on a flexible mount in the rear cockpit; there was also provision to carry two drop tanks or two 250kg bombs on under-wing racks.  This type entered service in August 1942 but was first used in combat during October 1942, soon being allocated the Allied codename "Nick".  The Ki-45 KAIa was joined by a new version developed especially for the ground-attack/anti-shipping role, the Ki-45 KAIb.  Standard armament comprised one 20mm cannon in the nose, a forward-firing 37mm cannon in the fuselage, and one rear-firing 7.92mm machine gun, plus the under-wing provision for drop tanks or bombs; a number of alternative weapon installations were tried experimentally, including the use of a 75mm cannon for attacks on shipping.

The Ki-45 KAIa was, for its day, heavily armed and proved quite effective against the USAF's Consolidated B-24 Liberators and when these bombers were used more extensively for night operations, the Ki-45 was adapted to attack them.  This is when the night-fighting capability of the type was discovered, leading to development of the Ki-45 KAIc night-fighter that proved to be one of the most successful Japanese aircraft in this category.  Ki-45 Toryu's remained in service until the end of the Pacific war, production totaling 1,701 including prototypes, being used for the defense of Tokyo, and in the Manchuria, Burma and Sumatra areas of operations.

 Mitsubishi Ki-15 "Babs"

For a brief period in 1937, the Mitsubishi Ki-15, code-named Babs by the Allies, was the fastest production aircraft in the world! The Ki-15 Karigane (Wild Goose) is a two-seat reconnaissance aircraft with a top speed of 300 mph.  Construction began in December 1935 and the prototypes exceeded all expectations.  About the same size as a P-47 Thunderbolt but only one-third as heavy, its range was four times that of a Spitfire and its ceiling was 6000 feet higher.  No fighter could catch it at the time.  1937 Newsreel Video

David’s New Design is an Exact 1/4 Scale, suitable for competition and/or everyday enjoyment at the flying field.  David finished his award winning model after the second prototype version, named Kamikaze-Go.  This unique aircraft has a colorful background which is highlighted in the "Construction Summary" downloadable from the Mitsubishi Ki-15 Babs menu.   1/4 Scale "Babs" Flight Video

Focke Wulf TA-152H

David's 1/5th Exact Scale Focke Wulf TA 152H goes beyond just enlarging his previous successful 1/6th scale version. This design is an exact scale version which brightens the aircrafts flight characteristics and incorporates several enhancements that allow you to use a broader range of equipment and transportation options.

The 114" wingspan allows for greater flight visibility, while the scale airfoil lets you feel why Dr. Kurt Tank's original design was considered to be the finest  performing propeller driven aircraft ever delivered to the Luftwaffe!



Design Specifications

114" wingspan, 1426 sq. in., 86" Length, DA 50cc or similar, 6 channel radio recommended, built-up balsa & ply, five plan sheets.

Lavochkin La-7


Grumman Lynx





The Lavochkin La-7 was a Soviet fighter aircraft of World War II. It was a refined development and  of the Lavochkin La-5, and the last in a family of aircraft that had begun with the LaGG-1 in 1938. Considered the last "Grand Piano", it was evolutionary rather than revolutionary. The two highest-scoring Soviet aces flew the La-7, one of them; Ivan Kozhedub was the top Allied ace of the war.


The Grumman light aircraft line was acquired by Gulfstream Aerospace in 1977 which formed their light aircraft division, Gulfstream American. After completing a major redesign of the AA-1B the new AA-1C was born. Two versions were marketed, differentiated by avionics and the external trim. The Lynx was targeted at private owners while the T-Cat was the flying school trainer.


Arado Ar 96 was a German single-engine, low-wing monoplane of all-metal construction produced by Arado Flugzeugwerke. It was the Luftwaffe's standard advanced trainer during the Second World War. For of you unfamiliar with this aircraft, the Germans use it much like we used our AT6/Harvard's. This is an extraordinary scale subject that flies as well as it looks.



Design Specifications

96.5" wingspan, 1704 sq. in., 3.7-4.8 cu. in., 6 channel radio recommended, built-up balsa & ply, five plan sheets.


Design Specifications

98" wingspan, 1642 sq. in., 3.2-4.6 cu. in., 5 channel radio recommended, built-up balsa & ply, five plan sheets.


Design Specifications

86" wingspan, 1060 sq. in., 1.5-1.8 cu. in., 6 channel radio recommended, built-up balsa and plywood, six plan sheets.

Pete's first race was at the 1930 National Air Races in Chicago. Winning five of the first seven races, Pete became one of the most successful racers in any form of motor sport. If you're a Thompson Trophy era aircraft fan you'll love the way the Pete handles both in the air and on the ground! The Howard Pete competed against the Gee Bee, TravelAir Mysteryship, Laird Turner etc.


The Focke Wulf TA 152H, a World War II Luftwaffe high-altitude interceptor fighter. The Ta 152H was a development of the Focke Wulf FW 190 aircraft, but the prefix was changed from "FW" to "Ta" to recognize the contributions of Kurt Tank who headed the design team. The TA 152H was the fastest (480 MPH) propeller-driven aircraft to see combat in WW2.
