На Мустангу је хладњак био врло осетљив (као и на Спитфајеру).
Погодак и обичног зрна би довео до цурења течности за хлађење (гликол мислим), после чега би се мотор прегрејао и зарибао прилично брзо. Због тога је код нас пало доста Мустанга при нападу на циљеве на земљи, а већина пилота преживела, јер су знали да су оштећени и имали времена да се склоне и слете безбедно.

XP-51G, један од прототипова тзв. ''лаких'' мустанга.
 Citat:... North American XP-51G-NA 'Mustang' experimental AAF fighter - 5 bladed propeller... https://airandspace.si.edu/collection-objects/nort.....photograph Citat:In early 1943, joint discussions were held between British authorities and North American Aviation dealing with the subject of what the next generation of Mustangs should look like... the structure of the Mustang was considerably heavier than that of the Spitfire, and it was felt that a considerable improvement in performance might be obtained if structural weight could be reduced... In January of 1943, North American Aviation suggested to the USAAF that they build a special lightweight version of the Mustang. It was agreed that a thorough redesign would be carried out, mainly to reduce weight but also to simplify systems, improve maintenance, and enhance performance without changing the engine...
The project was given the company designation NA-105... the last two of the NA-105 airframes would be fitted with Rolls Royce Merlin 145M engines obtained from England under reverse Lend/Lease. These aircraft were designated XP-51G and bore the serial numbers 43-43335/43336...
Work on the conversion... began in January 1944, with the Merlin 145M engines arriving in February. Five-bladed propellers were fitted, but the XP-51G was otherwise similar to the XP-51F. The date of the first flight of the XP-51G is a matter of some dispute--most sources claim that first XP-51G was flown by Ed Virgin on August 10, 1944, but the manufacturer credits Bob Chilton with the first flight on August 12, while other s claim that Joe Barton may have taken the XP-51G up for the first time on August 9. The second machine followed on November 14. The engine was the Rolls-Royce Merlin 145M engine rated at 1910 hp., driving a Rotol propeller with five wooden blades (almost identical to the propellers of the Spitfire XIV). However, the XP-51G flew only once with the five-bladed propeller during a 20-minute flight...
Neither the XP-51F nor the G ever proceeded any further than the prototype stage. The Merlin 100-series of engines had not quite reached the stage where they were fully ready for production. In the meantime, the Packard Motor Car Company had set up its own development program and had come up with the V-1650-9 version of its license-built Merlin, capable of delivering a war emergency power of 1900 hp at 20,000 feet with water/alcohol injection. Packard said that they could deliver this new engine starting in late 1944. Consequently, this engine was chosen to power the next production Mustang, which was designated P-51H. Neither the P-51F nor the G were developed any further, although the work on these two airplanes was invaluable in the development of the P-51H... http://www.joebaugher.com/usaf_fighters/p51_12.html

husky ::EOD ::bojank ::To je standardno, dosta pilota je trazila od mehanicara da urade grupisanje na manjem rastojanju.
koliko se sjećam piloti u tražili grupisanje na 800 ft nešto ispod 250 m.
Sve je bilo individualno od pilota do pilota...
Iako je pisano pre vise godina mozda ce nekoga zanimati.
Nije nista od pilota do pilota. Avion se unisanjava po shemi i priborom koji je predvidjen .
Nema niti je bilo niti je moguce unisanjavanje po zeljama.
