Hi !

My first model was a CL-215 (it still exists but does not fly any more) motorized with 2 OS .20 Max and at 1/14 scale (ws = 2040 mm). It was not under powerred because very light (styro + balsa wood + Kraft paper < 3500 g) and I would build the B-29 with same materials.

Hi !

The B-29 is my favorit plane and I would like to build a 1/14 model. Is there someone who make it ? My project is whith 4 electric engines for propulsion and approximative scale propellers (dia 14"). I have made an ugly draft for the forward cabin from some revues and internet plans because nothing does'nt exist on this subject with good accuracy ( only Tu-4 drawings have great dimensions !) ... May be someone could tell me if something exists for a better result ?

Regards

Quite interesting reading with this regards :
"Warriors and wizards : the development and defeat of radio-controlled glide bombs of the Third Reich" by Martin J. Bollinger.
Successes and limitations on both sides are shown very well. E.g., when the principles of the German glide bombs already were
known to the allies during the first phase of its use, it nevertheless sometimes was diffcult to equip even just one convoy escort
with a jammer.

I was able to finish this yesterday, actually.  Each of the systems deployed prior to early 1944 were capable of jamming only an individual frequency, and there was no way to coordinate in a timely manner among the equipped escorts. The highest number of escorts so equipped in an engagement prior to Feb 1944 appears to be three. Which means if nine glide bombs were launched, a maximum of three were capable of being jammed. It required the manual interception of the signal and manual tuning of the jamming equipment to same.
The location of the antennae on the Hs 293 made jamming from the frontal quarter difficult.  The ideal location for the escort jamming was between the glide bomb and the attacking aircraft. This was difficult when the most frequent use was against picket escorts and stragglers.
The USN decided against jamming the intermediate signal (as the RN did successfully with the type 650) because it was adjudged to be too easily side stepped by a change of the IF, which the Germans did not do operationally but was entirely within their capabilities.

Only one in nine glide bombs launched and observed to be responsive to control hit targets. Including mechanical failure, interception, etc, the number falls to one in twenty-four glide bombs leaving German airfields were adjudged to hit their targets.

Alot of technical problems would've been shared by the  BV 246 (mulitpath interference, weak signal strength at maximum operational [hence frequently terminal phase] distances, stalls during aggressive maneuvering).

Overall the jamming was not considered effective, especially early.  Disappointed that they gave only a brief discussion of EO and wire guidance which were both developed but never operationally deployed.

Frederick Forsyth, The Devil's Alternative, 1979

United States

USS Moran
Warship of unspecified type/class
Only detail provided is that the main gun armament is two 5 inch guns, one forward, one aft. This armament would fit either the Spruance or Kidd Class Destroyers.

United Kingdom

HMS Argyll
County Class Destroyer?
Details as per the real ships.
Note: Author refers to this ship as a 'Guided Missile Light Cruiser' but the limited details he provides best fits the County Class. However at one point he describes the ship as having identical gun armament to the USS Moran, given that the Royal Navy does not use 5 inch guns, nor a fore and aft gun layout, I suspect this is a mistake on the authors part.

HMS Cutlass (P274)
Scimitar Class Fast Patrol Boat
Real ship, details as in service
Ship was sold to Greece in 1981, novel extends the ships service to 1983.

HMS Sabre (P275)
Scimitar Class Fast Patrol Boat
Real ship, details as in service
Ship was sold to Greece in 1981, novel extends the ships service to 1983.

HMS Scimitar (P271)
Scimitar Class Fast Patrol Boat
Real ship, details as in service, novel extends the ships service to 1983.
Ship was sold to Greece in 1981

France

Montcalm
'Light Cruiser', class not specified
No other details provided.
Note: Name clashes with a  F70 (Georges Leygues) Class Frigate that was completed in 1982, it is possible this was the ship intended, but the author provides no details beyond the name/type to allow confirmation.

Holland

Breda
'Missile Frigate', class not specified.
No other details provided.

Germany

Brunner
'Missile Frigate', class not specified.
No other details provided.

Plot summary: The story runs between 1982 & 1983, the United States and United Kingdom have received intelligence that the Soviet wheat harvest has failed dramatically due to a series of errors of during the production of a seed dressing. Realizing that they have the Soviets over a barrel, they negotiate a hard deal for the wheat needed to stave off starvation in Russia, knowing that as they do so there is a faction of the Supreme Soviet willing to go to war to take the food they need. Then two Jews flee to the west and the Soviet negotiators make their return a precondition of the wheat deal. Before any decision can be made on this unexpected demand hijackers take over an oil tanker off the Dutch coast and threaten ecological catastrophe unless the two men are allowed to go to Israel. Now it is the West's turn to face an agonizing choice...

... What would be the point of that configuration? 

Perhaps to be able to carry objects, that need more ground clearance ? At the rear fuselage, there
seem to be struts and the wing center section looks thicker, than the standard wing.

I always understood that the British MoD used a series of computer generated randomly chosen words for their operational codenames.  While the US DoD used names which had a PR purpose,  as well as a security reason.
