P-40C Flight Testing
Finished the Service Ceiling and Absolute Ceiling tests last night:
Starting with half fuel and full ammunition:
Service Ceiling 32,700 feet
Absolute Ceiling 33,900 feet
Actual reported Service Ceiling for the P-40C was 29,500 feet which I believe sounds a bit too low.
I am reasonably satisfied with the results.

speaking of tanks and switches,
(yeah, it's a stretch)
Ivan, as I recall, long ago,
you were looking for a multi-position fuel tank switch
for your Dauntless...or am I dreaming?
did you ever find one?
I may have good news.
Hi Smilo,
Attached is an image of the SBD-3 Dauntless fuel selector. This is kinda goofy, but I would be satisfied if there were a gauge that could select Left Main, Right Main, Left Aux, Right Aux. The Reserve is a standpipe reserve in the Left Main tank.
Thanks.
- Ivan.

Hi smilo
Are-you the smilo12334 (spurious numbers) that is, among others, trying to talk some sense into the bozo who pretends on YouTube that the Mossie was all-metal, British only pretending it was wood to intoxicate the Germans into loosing time and money into building one? If so, a word of advice; don't loose your time into a desperate cause.
That guy is to place with those who believe that earth is flat and, believe it or not, one phenomenon who affirm that Hiroshima and Nagasaki were not nuked but flattened with "classical" incendiaries! I've seen him being kicked-out of at least three forums. He tends to be very crude with those who try to say otherwise.:isadizzy:
Hi Ivan
I have such a gauge that can be switched on Right-Main, Left-Main, Right-aux, Left-Aux, Normal (all) or Cut-off. I think it works only with 302-1003 "FS98 style" sections, but I'm not sure. I will try to test it with a tweaked "CFS1 style" tanks air file. It's a modified gauge that I used for an "extravaganza" F-16A panel of mine. Jet air files are only working with FS98 air files as CFS1 has only piston engines.
Incidentally, I have found HERE and HERE documents that describe the fuel capacity of the Mosquito B Mk IV and B Mk IV ii as being 536 gallons (I presumed Imperial) internal. Interesting fact; it goes down to 500 gallons with the "bulging bomb bay" version. Central main tanks gone?
It would also mean that the tanks were different between B Mk IV and FB Mk VI. Maybe the FB version had smaller wing tanks to increase roll rate? (I'm hypothesizing here...)
The range would have been barely enough for a Berlin bomb run, which fits operations reports.

Hi Hubbabubba,
Let me know how the gauge testing works out. Also, where did the gauge come from?
The unpainted screenshot below shows the changes from your comments about the bleeds. Note that the split between the fin and tailcone has changed. The red triangle above the front of the wing fillet cures the fuselage bleed problem.
The other screenshot shows what the P-40C changes look like with the original P-40E paint. The untextured major components are the most major rebuilds in which not only were the polygons changed, but the entire component was deleted first. Looks like a roadkill to me.
I also checked out the roll rates for the P-40C. They are an almost exact match to the documented results up to 350 mph IAS. I did not test beyond that because of the severity of the dives needed to get to that airspeed.

nope, I am not said, smilo1234.
I do not argue politics, religion,
or war denials in public forums.
the effort is an exercise in futility.
attached is a picture of the seven position fuel switch that I have.
I believe it was created by Chuck Dome.
I do not have the skills to change the gauge,
but I would imagine that redoing the gauge BMP
would not be that tough.
so, I had a thought about mosquito fuel capacities,
what if the air file was changed to reflect
the quantities with the wing slipper tanks?
granted, the tanks would not be visible in the model,
but, the long range mission could be accomplished.
the whole package could be renamed,
Mosquito B Mk IV LR
LR being Long Range
kinda hokey, but what the heck

Here's an aircraft that has been awaiting flight testing and a new panel for a few years. It differs from the Corsair uploaded here in that the canopy is different and the wing bend has been relocated inboard along with the landing gear. There are some dimensional inaccuracies though.

The P-40C has spent the last week or so in the paint shop. The P-40C is much fatter than the P-40E, so a few textures needed to adjusted.
The rudder was rebuilt to minimise a bleed that Hubbabubba found. The problem was that the NEW rudder extended past the bottom of the texture. In order to texture this, (0.bmp) the fin and rudder needed to be moved up. They collided with the main gear struts and the tail wheel. The tail wheel was moved.
As you can see from 4.bmp, there isn't a lot of space between the fuselage textures and other pieces here. Because the fuselage is deeper, the wing fillet needed to be moved to another texture. From the earlier screenshot, you can see that the top of the razorback section of the P-40C extends past the top of the texture.

As a general texturing note, it makes sense to lay out textures in such a manner that a single continous line can be drawn for the entire length of the fuselage. Putting a "Lightning Bolt" on the side of the aircraft might be impossible otherwise. This would be the vertical dimension that needs to be tweaked.
Also, the Fore-Aft dimension should be tweaked in places that might have a national insignia or emblem so that the emblem CAN be drawn easily. I haven't done the fore-aft check yet on this aircraft but the intention is there.

Been on vacation for the last week. Didn't do anything on the P-40C until last night. Did some layout of the panel lines on the fuselage tonight. This is mostly done. Wing panels need to be adjusted some. Exhausts and Radiators also need textured still. Note the goofy texture on the far side wheel? This texture file is shared with the control panel which still needs textured. I didn't want to lose the instruments, so I shifted things around temporarily. It will be done another day.
Time for Bed.

Painted the Exhausts last night. Also adjusted the AIR file for neutral pitch with the flaps down and "Nose Heavy" with landing gear down.
After the adjustments, I took a fairly long (half hour) test flight. I found another half dozen issues that need addressed. Most of them were fixed this morning.

Exhaust pipes looks great from that angle.
Bravo!

Hi Hubbabubba,
I still need to paint the Exhausts a darker shade on the bottom. They did end up looking better than I thought they would.
Here is some detail that you might appreciate:
Originally, I had not glued the Nose to the rest of the Fuselage. The Exhaust was glued directly to the side of the Nose.
I found that I was getting some bleeds from the Wing Fillets through the Nose from the opposite side, but only from Below.
This morning, I threw in a fore-aft glue part between the Nose and rest of the Fuselage. After THAT, the Exhausts bled through the Wing Fillets. After reworking the glue parts for the Exhausts, the bleeds pretty much went away.
BTW, I forgot to mention, the trim changes with flaps and landing gear were from the Pilot's Manual for the P-40 Tomahawks. The original flight model didn't have these traits because I didn't know about them.

Notice I am still going lower? I am just lining up on one lucky Daisy at the end of the runway.
BTW, I reworked the fuel tanks to put them in the order of their physical locations:
Reserve
Main
Fuselage
I also changed the bitmap on the control panel to put a letter (R-M-F) next to the switch position.
I had fun crashing it last night: Belly landing (plane sinks into the ground), and nosing it over to check scrape points. Also tested the clean stall speed: 85 mph or so. Adjust the stall warning to 13.5 degrees so that it now comes on just BEFORE the actual stall instead of after.
Still Working.

I guess it's that time again. I am considering the next project to build.
So far the short list has the following:
Mitsubishi J2M3 Raiden 21
Kawanishi N1K2-J-Ko Shiden-KAI
Messerschmitt Me 109G-10 or K-4
Yeah, I know everyone has built a Messerschmitt, but I want to own one. I don't believe I have ever seen a good Raiden or Shiden-KAI.
Any other suggestions?
