Default What happened with G50 FM ?

After final patch it has become unflyable, stuttering all the time.
Or doing something wrong?

Check mixture and decresase it the higher you fly... last Saturday easyly climb at 5000m, 340 IAS... lot of fun against Wellies !

I already tried this, flying low with full and zero mixture, still stuttering.

As funny as it sounds you may be running the engine too cold, try closing the radiators some and see if that helps at all. Also make sure to adjust prop pitch, it's very finicky.

I did this as well, strange thing is that the temperature of the engine remains 0 degrees.

IIRC you have to press a button/turn a dial near the engine sensor on the dash to get the reading.

The G.50 and BR.20 are very finicky. If they're too cold they lose power and shake. They need to be ran hotter than you think.

Yes you select the cylinder head to see the temp. If it is at the top you haven't select one and wont see a reading.

Ok found the switch. Radiotors 20% open and engine temp around 200 degrees to run smooth. Thanks.

Salute

The G-50 is actually one of the best modelled aircraft in the Sim now. It now has WEP power modelled, which can be used for limited periods.

The G-50 has a radial air-cooled engine, As people have mentioned, you need to make sure your Cylinder head temperatures and oil temperatures are correct before you attempt to take off.

Oil temperature is controlled with the oil radiator, which is normally opened to about 25%, cylinder head temp is controlled by the air vanes which open at the back of the engine to allow air flow, these are controlled by a player with the same input as a glycol radiator.

Oil temperatures should be approx. 70 degrees C prior to takeoff and somewhere around 70-80 for inflight and avoid going over 90C. Cylinder head temperature should be 200 degrees C and many people run it about 220 degrees. Try to avoid going over 250C for longer periods, and don't go over 300 C ever. If you let the oil temperature drop below 60C or the cylinder head drop much below 200C, you will get missing on the engine, this is probably what most players report.

Start up is done with oil and radiator vanes closed. There is no fuel cock, you don't need to open one, there is a standard dual Mag, with three positions, 1,2, and 1+2 (use the last) and you should give the manual fuel handle a few pumps. Crack the throttle about 10-15%. You can reduce the heat up time of the engine after the initial start, by increasing throttle slowly till the engine starts to miss, then backing off, and repeating. Obviously you need to keep your brakes on while doing this. Keep a close eye on your oil and cylinder head temps when warming up. You need to select a sensor to monitor your cylinder head temps, the multi position switch is on the right dash, each position monitors temps at two cylinders, usually I set it to the middle position and leave it there. You may need to open the oil rad during warm up, before the rad vanes, the cylinder heads usually take a little longer to warm up to proper operating temps and oil can overheat while you wait.

Make sure you open the radiator vanes prior to takeoff, usually approx. 60%. Pitch on the constant speed prop is set to full fine, 2520 rpm, boost to either max throttle, 740, or WEP, 840, although you really don't need to go WEP for takeoff. After takeoff, reduce pitch and rpms to 2400 till you are trimmed out, then 2250 rpm for continuous running or climb.

Beyond the engine temperatures, the G-50 also must have its gas mixture managed.

Mix should be 100% on start and takeoff. As you climb, you will need to reduce mix to allow for the less dense atmosphere at higher alts. Usually you need to start reducing mix around 1000 meters. Again, the engine will start to miss if you don't adjust the mixture, but even before it starts to miss, rpm will drop. Adjust the mix by watching your rpm gauge and adjusting for max rpm.

The G-50 is a fun plane to fly, it has a lot of elements missing on other planes, for example, full trim for all the control surfaces, including elevator, rudder and ailerons. You can trim it out perfectly for hands off flight.

It does not seem to suffer from any altitude issues, other than the fact it was designed primarily as a low alt aircraft, it flys well at 4.5 thousand meters, where trimmed out at cruise settings, 2000 rpm and 650 boost, it will cruise all day at 320 kph indicated.

Maximum power, using 2520 rpm and WEP, (840 boost) can be used for only a short while, I recommend a minute or less. The engine is only capable of generating this boost at lower altitudes. Normal combat power is 2400 rpm and 740 boost, with sustained power at 2250 rpm and 740 boost. Low cruise at 2000 rpm and 650 boost. In all these, you need to be aware of your oil and rad settings, you can cool your engine too much as well as overheat it.

The engine seems quite thirsty at higher boosts and rpm's, watch your fuel, gauge on right side of seat, you need to pass your mouse cursor over it to get a reading.

The G-50 has flaps which are deployable in increments, you should use partial flaps for easier takeoff, and they are also useful in combat.

It can be a little tricky to land, make sure you use full flaps and watch for the low speed stall, you need to maintain some power otherwise the plane has a tendency to drop out from under you.

The plane also does have a nasty stall, you have to be careful not to pull too hard in turns. With flaps it will give Hurricanes and Spitfires a go in turn contests, although I would not rely on this, the excellent rollrate is perhaps more useful.

It is slower than all other fighters in the game, with the exception of the CR42, Gladiator, and perhaps the 110 at certain altitudes.
