Title: Grumman Piston Twins - XF5F Skyrocket and F7F Tigercat
Post by: ysi_maniac on June 21, 2012, 08:33:41 AM
Tigercat is quite sleek that's why I think she deserves sleeker engines like RR Griffon. Wings have been a little enlarged too.

A "simple" up-engining with a pair of R3350s, perhaps using Skyraider cowls?  A more ambitious racer version with R4360s?

To begin, what if the USN decided to actually procure the XF5F as a carrier fighter:

R-1820 was fine for initial flight testing.
Operational F5F with R-2800 engines entering service in early 1943 would wreak havoc on IJN.

I do have, as a future build plan, a centaurus powered FAA Tigercat in Operation Musketeer or Korean War era markings.

I might do up a French Navy one staying with R-2800 engines to go alongside it.

Does anyone know if Tigercats carried unguided rockets under the wings in real world practice?


I also thought the Tigercat might look good on floats as a bush plane. Considering that many found use as real world fire bombers, it wouldn't be hard to rig up a cargo capsule in the same fashion as the under fuselage retardant tank.

I liked the lengthened nose (but not the nosewheel) and spinners of various makes of this Grumman twin.

An obvious variation is a production Grumman P-65 in USAAF squadron markings.  I wonder how it would've evolved separately from the F7F?

The USAF would have stuffed cameras in the nose instead of a radar unit and used it instead of the F-51 complete with NMF and white polkadots on a red background.   ;D

This is a no go as the F-5E (the P-38 one that is not the Northrop one) nose is actually pretty big and there is nowhere to really append it on the stub-nosed Skyrocket. I'll have to go through my spare nose jobs but failing anything else I can always mount a podded radar in the vein of the P-38M and make her a nightfighter.

That is most unfortunate.  I recently experienced something similar but was trying to mate up a resin 1/32nd scale F-5 camera nose conversion to a 1/48th scale Lockheed Ventura and discovered that it was not going to work as I had imagined.  I might try to use the parts from the Academy P-38 kit that includes the BTO, F-5, and night fighter parts instead but that is still undetermined at this point. 

Might I suggest that for your own project that you expand your search to include something more rotund in cross section?  Perhaps the nose from the de Havilland Mosquito will work for your project, it has the more circular cross section that could mate up with the nose of the Skyrocket.  Looking for something that is not in the same scale as your Skyrocket might also work to your advantage.  Scale-O-Rama!

Well I've looked at a Ju-290, A-26, B-25H, P-38J and Mosquito nose but none have the right contours. I've also investigated using an inverted 1/48th Mosquito Merlin cut to fit (you had to be there). None of them look as good as that F-5E nose so I'm going to use the F-5E nose dammit!   >:(

I've cut grooves into the nose to get it to sit down onto the leading edge of the wing and am using bits of sprue to create a bridge between it and the fuselage which I can later fill in. So far so good. If it works, I'll start a build thread. If not, I'll be open to ideas and/or inspiration!

Folks:

I found yet another use of Ta-152 wings: F7F. Heh heh heh.  >:D

But I suspect to obtain sufficient power at 40,000' plus altitude, superchargers are  necessary mandatory.

How would you modify the Monogram F7F to incorporate superchargers? Push the engines forward but mess with the C of G?  Extent the engine nacelles back? Mount them on top like the P-38?

Engineers, please break out your slip sticks and fill my brain with laplace and fourier translations.  ;D

I would not push the engines forward, that adds more headaches unless you've got an equivalent weight to balance things.  Are you going with mechanically-driven superchargers or exhaust-gas-driven turbo-superchargers?  This make a big difference in potential layouts.  Too, in either case, will you be using intercoolers to get the temperature of the supercharger flow down?  This, too, makes a big difference in efficient component arrangement.

I'm not at all certain that you need to extend the nacelles, they look to be long enough now.  For one idea, you might want to look at the Japanese heavy high-altitude fighters from WW II.  ISTR that at least one had the turbocharger at the aft end of the nacelle with the exhaust pointing aft.

The F7F was powered by a two-stage supercharged R-2800, so what extra supercharger
are talking about adding? The F7F-3 version had a service ceiling of 40,700 feet, so any
big gain over that would probably be a matter of changing blower size, ratio, etc. None
of which would create much in the way of external appearance, except perhaps some
sort of enlarged air intakes. Possible, but not something that would necessarily happen
as Grumman and P&W seemed to work well together on creating extemely clean installations
in that period, which is demonstrated by both the F7F and F8F.

Stick on the long wings and just tell folks the blower system was tweeked for higher altitude.

Not sure if this for the XF5F or the F7F but it appears that tail perspex from the Frog Shackleton with a bit a styrene shim and PSR could give the F7F a glass nose.

Possibly painful on a hard landing, too (much like the P-38 trainers the Italians did).  Just a thought, what if the F7F had kept the twin verticals of the F5F instead of, or in addition to, the existing vertical tail (perhaps much cut down).

Interesting that the Plastic Borg mentioned installing the Vickers Class "S" class 40mm S Guns on a P-40.

I have plans (only on paper of course) to install a 75mm and maybe two 40mm guns on a F7F.  The 75mm could come from a Italeri HS-129B-3. Or would the cannon/barrel be shorter T13E1 / M5 design as installed in the B-25H (the online images of 1/72 B-25Hs kits do not have a full length cannon, just a stub). So would have the US used a stock 75mm barrel as used on a M4A3 Sherman? How accurate was the short barrel T13E1 / M5 75mm? 

Yes, there was the Beech A-38 Grizzly (http://en.wikipedia.org/wiki/Beechcraft_XA-38_Grizzly) with the new-designed T15E1 (M10) 75 mm cannon (http://www.firearmstalk.com/The-strange-case-of-the-flying-Grizzly-and-its-75mm-gun-Firearms-Talk.html).

(http://www.firearmstalk.com/images/5/8/0/6/3/dscf2750-2462.jpg)

But hey, the F7F/R-2800 were proven design, in mass production so why not retro fit it? The R-2800-34W produced 2,100 HP and 2,400 HP with water-methanol injection. Same HP as the A-38's R-3350. And the F7F was 90 MPH faster.

And BTW I have several F7F kits in the stash and no A-38s.  8)


NB: Don't forget there was the Vickers P Class 47mm cannon.

The other option is the 6pdr / 57mm Molins gun as installed on the Mosquito Tsetse. It was used for anti shipping strike but I believe was originally intended for anti armour and CAS.  Also, as I understand it the 6pdr has superior armour penetration characteristics to the US75mm.

That might be good.
The front view of the Tigercat is wonderful but something always bothers me about the side view. The real world canopy cannot be quite ideal for best visibility either.

Interesting that the Plastic Borg mentioned installing the Vickers Class "S" class 40mm S Guns on a P-40.



The Plastic Borg??

Yup. The WHIF hive mind.

I have plans (only on paper of course) to install a 75mm and maybe two 40mm guns on a F7F. 

Fire all three at once and the aircraft would probably fall out of the sky.

Agreed. There will be a switch interlock which prevents the arming of both cannons types at the same time.

Thank you. I have Trumpeter H-5 (IL-28) which will be more than happy to give up 2 × Klimov VK-1A turbojets to jet power a F7F.

The wing tip tanks on the old T-33 could be jettisoned in flight. Which is a heck of a thing if a pilot is practicing CAS and accidentally hits the wrong button! Army troops get terribly mad when they actually get bombed!

Tiptank jettison was no where near the armament panel on CF T-33's... not sure about those anemically-powered US birds. :)

On the Canadian birds the armament panel is by the pilot's left hip on the side console, the tank jettison is a big button on the main instrument panel. It's mounted on the lower, fixed, portion just to the left of where the stick would be at full forward extension. Not much chance of confusing the two.

I have plans (only on paper of course) to install a 75mm and maybe two 40mm guns on a F7F.  The 75mm could come from a Italeri HS-129B-3. Or would the cannon/barrel be shorter T13E1 / M5 design as installed in the B-25H (the online images of 1/72 B-25Hs kits do not have a full length cannon, just a stub). So would have the US used a stock 75mm barrel as used on a M4A3 Sherman? How accurate was the short barrel T13E1 / M5 75mm? 



Holy thread revival!!!  A Tigercat with Beech XA-38 Grizzly (see below) style proboscis would look cool.

The barrel of the 75 used on the B-25H was a lightened, thin walled
version and was not the same as used on the Sherman.
The autoloader version developed for the Grizzly would not fit in an F7F.

Random idea:  RAAF Tigercat instead of Beaufighter. Use this sort of scheme:

And if memory serves me correctly this lightened version formed the basis of the gun used in the Chaffee.

I recall reading the USAAF trialled the 75mm against the Molins Gun and were very impressed with the Molins. Extrapolate this with the knowledge that the 6pdr that was the basis of the Molins, was subsequently rebored to use US 75mm ammunition we have the potential of a 75mm Molins gun in USAAF aircraft.  ;)

I really like that. I hope you won't be offended by a suggestion? Perhaps raise the wing slightly to a more F7F-representitive position (shoulder high) and blank out the middle section of the canopy (where the wing spars would now go through), leaving the rest as is? I think that could really turn some heads.

Japanese reply to the Tigercat - the Kawasaki Ki-108 - pressurized cockpit.  There was also a turbo version for high altitude work.
