PROJECT TED NO. PTR - 1115

FM-2 vs TONY I TYPE 3

CLIMB: The FM-2 is superior at all altitudes.

SPEED: The FM-2 is slower at all altitudes.

TURNS: The FM-2 is equal or has slightly smaller radius of turn.

ROLLS: Approximately equal at low speeds. FM-2 slightly superior at high speeds.

ACCELERATION: The Tony I is superior.

ZOOM CLIMBS: The Tony I is superior.

SUGGESTED TACTICS: Attempt to capitalize on the following advantages of the FM-2 over the Tony I type 3
a. Greater rate of climb.
b. Superior high speed roll.
c. Equal or slightly smaller radius of turn.

Avoid the following disadmantages:
a. Less speed.
b. Less acceleration.

TAIC REPORT NO.17 November 1944

COMBAT EVALUATION OF THE ZEKE 52 WITH F4U-1D, F6F-5 AND FM-2

REPORT BY U.S. NAVAL AIR STATION, PATUXENT RIVER, MD.


A6M5 Zeke 52 vs. FM-2

CLIMB: The A6M5 is about 400 fpm slower at S.L. Equal at about 4,000 ft., 500 fpm better at 8,000 ft., became equal again at 13,000 ft. and was slightly inferior above 13,000 ft.

SPEED: The Zeke 52 was 6 mph slower at S.L., 4 mph faster at 5,000 ft. and progressively faster above that.

ROLL RATE: Equal below 160 knots and FM-2 superior above 160 knots.

***TURNS: Turns of the FM-2 and Zeke 52 were very similar, with a slight advantage in favor of the Zeke 52. The Zeke 52 could gain one turn in eight at 10,000 ft.**************************************

DIVES: The Zeke 52 was slightly superior to the FM-2 in initial acceleration, after which the dives were about the same.

MANEUVERABILITY: The Zeke is remarkable at speeds below about 175 knots, being slightly superior to the FM-2. This diminishes with increased speed and the FM-2 has the advantage at speeds above 200 knots (230 mph.).

SUGGESTED TACTICS:
a. DO NOT DOG-FIGHT WITH THE ZEKE 52.
b. Maintain any altitude advantage you have.
c. To evad a Zeke 52 on your tail, roll and dive away into a high speed turn.

The General Motors FM-2 Wildcat VI, Jeff

FM-2 WILDCAT

The following performance information is probably typical of most FM-2s fresh off the flight deck. However like all fighter aircraft, it could be stripped and cleaned for slightly better performance if the need were to arise.

I just very recently was directed to this excellent site. The following information can be found there.

From the little I have read to date, the FM-2's over all performance was a

surprise to the A6M5 pilots. The maneuverability difference from all earlier models

of F4Fs and the newer Zeros was greatly improved by the FM-2's new gained power.

At very low and medium altitudes the FM-2 had a distinct advantage in climb. This

was a nasty awakening for late Zero pilots.

 

America's Hundred Thousand:

Page 494:

     " The (FM-2's) generous wing area led to a moderate wing loading compared

to some (most) other US production fighters and the FM-2 could therefor out-turn

them. The type could give a good account of itself in aerial combat properly flown;
one corsair pilot found it hopeless to try and stay with an FM-2. But escort carriers

with FM-2s never purposely sought combat with Japanese fighters.

     There were no particular diving limits with the FM-2: terminal velocity dives

were allowed with or without wing stores.

     The FM-2's maximum maneuver limits were 7.5g up to 7,700 lbs. and 7.0 up to

8,200 lbs.
