The Mohawk (OV-1) Society has an illustration, originally in their newsletter, of Grumman's COIN derivative of the Mohawk on their website, though it takes a spot of digging to find it. I did copy it and will be glad to share (I cake it we can't attach picture files directly here). It looks like you could use the cockpit and front end of a Pucara combined with an OV-1 airframe to model it. It's on my list of models to build.

Here an image of the scale model of the G134R
Of course that the true men go to the war in airplanes with motors of constant speed,picturesque names and helms in T.
(Pardon for the chauvinistic comment t - in fact I like but the design of Grumman -
but I live near where the Pucará is manufactured and I don't want to be wakened
up at 5:00 o'clock by offended pilots flying to 10 mts) ;D

Sorry gents
This is my first time on this site - great job and good work
Im glad to see that others share my interest in aviation - especially prototypes.
I have to say sorry in advance - but the Grumman Model G-134R was infact Grumman's design submission to the USMC (US Navy) 1960's 'LARA' (Light Armed Reconn Aircraft) comp - (which was won by the North American - Rockwell OV-10 Bronco design) and not the USAF's 'AX' program.
The 'LARA' program itself would be another good thread!
Some very interesting design with that comp too!
Look forward to visiting soon
Regards

The Bronco began with a specification approved by the U.S. Navy, Air Force and Army, a "tri-service" specification called "LARA" (the Light Armed Reconnaissance Aircraft), issued at the end of 1963. LARA was based on a perceived need for a new type of "jungle fighting" versatile light attack and observation aircraft. Existing aircraft (the O-1 Bird Dog and O-2 Skymaster) were perceived as obsolescent, with too small a cargo capacity for this flexible role.
The specification called for a twin-engined, two-man aircraft that could carry at least 2,400 lb (1,100 kg) of cargo, six paratroops or stretchers, and be stressed for +8 and -3 Gs (basic aerobatic ability). It also had to be launchable from an aircraft carrier, fly at least 350 mph (560 km/h), take off in 800 feet (240 m) and convert to an amphibian.
Various armament had to be carried, including four 7.62 mm machine guns with 2,000 rounds, and external weapons including a 20 mm gun pod and Sidewinder missiles.
Eleven proposals were submitted, and seven made the first cut: the Beech PD 183, Douglas D.855, General Dynamics/Convair Model 48 Charger, the Helio 1320, the Lockheed CL-760, a Martin design and the North American/Rockwell NA300.
In August 1964, the NA300 was selected. A contract for seven prototype aircraft was issued in October 1964.
General Dynamics/Convair protested the decision and built a prototype of the Model 48 Charger anyway, which first flew on November 29, 1964. This was also a twin-boom aircraft that had a broadly similar layout to the Bronco. The Charger, while capable of outperforming the OV-10 in some respects, crashed on October 19, 1965 after 196 test flights. Convair dropped out of contention.

Thanks for all these pictures of poorly known twin-boomers ;D
What a joy!

I don't know it. It Seemed not to have it, even books like "Naval Fighters 39-Convair 48 Charger" that gives quite detailed information about this model doesn't give any number.
Neither I have been able to get some detailed information on the proposal of Helio. (Helio1320)
Maybe if some of the members of the forum that write professionally on these topics requests them information he obtains some answer. I don't make it because I don't believe that they respond to an Argentinean fan that speaks English pitifully.

Seems that there was not any number. It is interesting, because other proposals have some:hesham said:
Beech PD-183
Convair Model 48
Douglas D-855
Goodyear GA-39
Grumman Model 134R
Helio 1320
Lockheed CL-760
Martin LARA
North American NA-300

Why do you think it?Dronte said:
Helio info, as written in Aerospace Projects Review V4N5:
Very similar to the Beech PD-183, the only major external difference in configuration was the location of the horizontal tail. A perceived advantage for the Helio craft was that it was to be derived from an existing plane, the Helio U-5. The model 1320 was to have a welded steel tube truss construction, with fiberglass skin panels. To aid in low speed lift, the wings were to be equipped with leading edge Handley Page slats and electrically operated full span double slotted flaps.
Span: 9,14 m
Lenght: 12 m
Height: 4,57 m
Powerplant: 2 x Garret-AiResearch T76-G-6/8 (660 shp each)
Empty weight: 2161 kg
MTOW: 4086 kg
Max. speed: 529,7 km/h
Sentinel Chicken
American 71 Heavy, contact departure 126.47
That is one NARROW track landing gear on the Goodyear design. I can't quite tell, but I presume the wingtip pods housed guns?

Also from aero February 1965:
- GA-39 based on the Duck amphibium
- the small span allows transport without folding the wings
- extensive use of plastic elements was planned
- extendible hydroski for amphibian purposes/duties
- span : 7.01 m
- length : 8.53 m
- height : 4.11. m (2.31 m up to canopy)
- span of horizontal tail : 3.66 m
- gross tare weight : 1,663 kg
- max speed : 510 km/h
- TO run (up to 15 m) : 457 m (at 590 kg payload)
Sorry, SC, no details on possibly armament in the wingtip pods.

Yeah, it was an amazing STOL. It could take off in 225 ft. clear a 50ft object in less than 500 ft and during one of the tests one of the pilots flew it at 30 KIAS at 200 ft altitude (MSL) on one engine! That Naval Fighters Number 39 on it is excellent. It also has all of the larger versions they could have developed from it in that publication as well.
