Zur and Razer,

Are there any major differences in the performance or flight characteristics of the P-47D bubble canopy and razorback versions?

If not, I was wondering how much work it would be to turn the razorback into a D version first and THEN make a C version?

Razer-
I still need the list of work to be done on the C. Can you send it to me? Thanks!

Sorry, been kind of busy.

1. Front cockit frame needs to be changed to a C model.
2. Lower LODs on the fuse need to be changed to the C model (just move the polys to simulate the razorback version. theres no need to do new models.
3. Update the FM to be the C model.
4. Update info for the C model and redo the loadout for C model weapons (could be the same i don't know)
5. anything i may have left out.

Does the P-47C Razorback use the P-47D FM?

The D model razorback and bubble version have the same flight characteristics, wing, elevator, and rudder structure from what I've read so far. The only difference is the alcohol injection in later D models which isn't modelled yet in SDOE. But the earlier model bubble versions didn't have it either.

If this is true there are only minor changes needed to the razerback (if it uses the current p-47D FM) to make it a D razerback.

Then we could go about making it a C version.
Found the changes needed for the loadouts, too.

One other note, from one source, when carrying lots of fuel (i.e. 2 wing tanks and a belly tank) or a heavy bomb load, only 6 guns were armed to save weight. Have you guys run across this too? This was the first time I've heard about this alteration.

If so can the loadouts be altered to 6 guns when loading the D with bombs & rockets?

Personally I would prefer an early D model razorback over a C model any time. The performance at altitude was broadly similar in both models, however the D introduced water injection giving the R2800 an extra 200hp for a limited duration. And just as importantly, introduced the paddle blade prop which dramatically improved the climb performance at lower altitudes.

The early bubble tops lacked the tail fillet - later retrofitted to earlier models and then introduced later in subsequent versions. Because of this they were noticeably less stable in the lateral plane, the early P-51Ds had similar problems following the introduction of the bubble canopy.

As most of the fighting in SDOE is at low level and as the P-47D (in bubble top form) is already a limited dogfighter, I would rather see the superficial change to the an early D than an FM modification that would go with a C model. The C would be serious out classed in fighter vs. fighter combat in all but hit and run engagements.

The 8th AAF used it to great effect in the above role, but they were operating at high altitude where the performance of the P-47C was in many areas comparable or superior to the Fw190As, Bf109s and Bf110s it encountered. Unfortunately SDOE does not model these differences at altitude very effectively.

Thanks Yard. Saved me lots'o typing.

Just to add as previously noted:

*engine rating
*lateral instability (not horrific but less than say a D)

Also the tail unit on early (non-filleted) Cs had been know to break.

If ya need "specs" let me know and I'll post the numbers I've got to compare the two.

Yardstick,

Actually the water injection wasn't initially added to the D. Thr write up I saw listed the serial#'s of the d model aircraft shipped without it and the starting numbers of the series that shipped with it.

The rest of your post is along the lines of what I was thinking too, although I would still like to have a C for doing bombing missions along the coast and in France.

I guess I'm wierd cuz I like the looks of the razorback version better. To me it somehow, looks meaner.

As far as the loadouts go, most of the shackles placed on later D's were field fitted to the razor back. It looks like the only changes needed here would be to have additional loadouts that reduce bomb load and xtra fuel capacity for early D models.

"already a limited dogfighter" Them's fightin words , come on, (ducking and dodging, punching the air) I'll murderlize ya

Actually, fast was surprised that I was able to get on his tail and stick there when he was flying an Fw 190 on newbie night. Were were fighting from ground level to 4000 ft. Sailor was there. There are some tricks this bird can do that surprise a lot of people. And because of the wonderful job Zur did, they're the same tricks used in the real P-47D.

This plane is the best allied B&Z fighter in SDOE AFAIK. And eight .50's can chew a plane up pretty badly. You'll get hit in a dogfight, but like the real P-47, if it's airframe damage, you're still very much in the game.

Okay, I now know where to start here, seems like a D Razorback would be desired before a C model.

Zur, can you send me the info on the D you have rather than post it?

Thanks.

According to 'Thunderbolt' by Roger Freeman, the D-5-RE was the first production Thunderbolt fitted with water injection. However some earlier versions were fitted with the kit prior to its indroduction into the production run. I think Bud Mahurin lost an aircraft when using water injection because he forgot to manually switch fuel tanks and flooded the cylinders with water.

The D-22-RE introduced the Hamilton Standard paddle blade prop.

there are major differences between P-47C thru P-47D models. yes they use the same basic wing and elevator etc, but there is a large difference in weight and hp. early P-47C had only 2,000hp and weighed about 12,500lbs late d models were 1-2000lbs heavier also D models had different hp ratings that varied from 2,000, 2,300, or 2,600hp. fuselages were longer etc etc. there are many differences just among the D models. all pre dive recovery flap P-47s should have problems in a dive with compression. late D models had dive recovery flaps added.

Ummm

Just so there's no confusion, the question is not about the differences between the C an D models. I already know that will require some major work.

The question was whether the FM's of the D Razorback and bubble canopy versions are similar enough to only require some minor tweaking of the model Razer released so it can be released as a D model razorback first.

This appears to be so.
