Mosquito, how to take off?

[Bestmann]

Hi pilots

 

I am unable to take off with the new Mosquito. It pushes me around in circles to the left and right. Differential braking and splitted throttles on my TM Warthog make no essential difference. Is there a good guide or video that explains how to do it correctly? I have quite some flight experience on most of the other multi engine planes of the sim. This one really puzzles me. It is way worse than the Ju 52 which I thought to be the greatest challenge on take off. )-:

 

Any ideas are appriciated.

 

Thx

The best I've been able to figure is to treat it like I do the Spitfire.  Hold the stick back, throttle up quickly and smoothly and get the airflow going past the rudder ASAP. Stab left/right brakes as needed until rudder control becomes effective. Let up on stick to center position slowly until ready to lift tail.  After tail lifted, rotate to liftoff at correct speed.  Probably totally incorrect takeoff procedure but, I get about a 75% success rate with it.

One good thing about this Mossie is it does not nose over with the slightest touch of the brakes.

dont forget that differential braking on the mosquito only come from using the rudder pedal plus brake lever.  Unlike every other twin in game. As mobile bbq says means alongside the poor/non existant rudder control at low speed it needs to use brakes early in run to keep straight and for me a steady application of power (I found its easier than rapidly applying), I get airborne pretty much every time.

IRL the airplane had a tendency to pull/swing to the left. As a result pilots would lead with the left throttle. See this post.

 

 

However this model does NOT behave like the real thing on the ground. For that reason I physically link my HOTAS throttles to get symmetrical thrust as I advance the throttles.

 

I use 15 degrees of flaps, and I set 80% rpm prior to brake release as that will give me ~2800-2850 rpm (normal climb rpm setting) when I set ~80% throttle which is really close to 9 lbs of boost. So without holding the brakes, I initially push the throttles to ~25% allowing the airplane to start rolling then smoothly push the throttles to 80%. In this manner I only tap the brakes 1 or 2 times on average between that 25% and 80% throttle setting.

 

It seems to me that the biggest challenge is getting your speed above ~50 mph. Once I'm above that speed I can relax the amount of left rudder and stop tapping the brakes.

During take off, my L/R breaks are just not responding with the Mossie, anyone else experiencing this ? I use a Thrustmaster 16000M, buttons 4 and 5

British a/c use a lever for the brakes like a bicycle, and you need to use your rudder to get the brakes working on the side you need.

I have brakes on an axis which would seem like the way to go. Been a while since I've flown the Mossie in GB, but I was able to get it off the ground and land pretty consistently without groundlooping. The Mossie is more demanding in DCS  ?

Try increasing the RPM to 3000, remembering to reduce at the right time of course. In the Spitfire, it's easy to ground loop when taxiing if there's not enough air flow over the control surfaces. Having higher RPM helps.

Brakes on mossie need to be set to a button, as its lever operated.  I'm flying a mossie career atm and take-off is simple:

 

1) Max RPM

2) Slam that throttle up to 100%

3) Nose down ASAP to get more airflow over the rudder

4) Rotate

 

To course correct if required tap the brakes while using rudder to deflect to the required direction.

I have a brake lever on an axis. Why would a button be needed if an axis is available?

Been spending a lot of time with the Mosquito and also had difficulty taking off. Since there is no Requiem video, I consulted the pilot notes for the FB6:

 

https://zenoswarbirdvideos.com/Images/Mosquito/MosquitoFB6Manual.pdf

 

Official procedure for taking off was:

 

-RPM = 100%

-flaps = 0 or 15 degrees

-throttle = gradually increase power

 

You can use differential throttle or brakes to keep the AC moving in a straight line. The problem as I see it is that there is a lag of a few seconds before the AC responds to differential throttle input/brakes, so if you keep differential throttle/braking on until the AC reacts, you will be overcompensating and ground loop. What you have to do is anticipate the AC and use small throttle or braking input. Once you get the hang of it, it is quite easy. Practice makes perfect.

 

Now one issue I can't figure out is why the AC has a tendency to turn right when taking off. The torque effect is correctly modelled since if you fly level with aileron trim at neutral, the AC has a tendency to roll counterclockwise which is what you would expect with two propellers rotating clockwise. Having spent a lot of time with the AC and comparing it with the pilot notes, you can also see that the IL-2 Mosquito is a very good reproduction of the real AC.

I tend to use RPM at about 40-50% at the end of the runway. Go gentle to full throttle and then feed in the RPM whilst dancing on the brakes to keep her straight. Other squad mates do it differently so find a solution that works for you and your set up and stick to it.

[ROCKET_KNUT]

Tried this method yesterday on CB:

-line up on the rwy.

-set pitch-, roll- and yaw-trim to neutral,

-set flaps to half,

-set rpm to max.,

-apply brakes,

-apply full throttle rather quickly,

-once the brakes no longer hold the a/c, release the brakes,

-make corrections as described above,

-look smug and wave to the crowd as you thunder down the rwy,

-once reached 60mph bring back the stick to neutral whilst accelerating further,

-take off at around 100mph,

-tell yourself what a great pilot you are...?

It worked much better than the cautious approach I tried earlier this evening.

If this technique works for you then by all means use it, but realistically you always lead with RPM when adding power (and lead with throttle when reducing). You want fast acceleration and airflow over the tail; that is best done with high RPM. Which is pretty much why you almost always push your props up when in the pattern (or a fight).

 

Splitting the throttles helps and is fun if you have the proper controls.

 

Mossie is a fun plane to fly, both in IL-2 and the "other" sim.

Necro-replying because this topic has recently come up several times in the WW squadron ...

 

Because on the Mossie, and several other aircraft (Spitfire, Hurricane, and anything without toe-brakes that use that convenient brake axis control) the brake axis does nothing. The brake button (lever in real life, like a bicycle's hand-brake lever) in conjunction with the rudder is what provides directional maneuvering on the ground. It's a bit fiddly at first, but once you get accustomed to the process, it becomes easy ... second nature or muscle memory.

I have brakes on lever in three flight sims where there are Spitfires and in two with Mossies. I use lever in conjunction with rudder pedals. Very convenient in VR.

[Spidey002]

I used joystick gremlin to split the axis on the paddles on my TWCS throttle. I use the left one as a brake lever for British planes (I use toe brakes on my TFRP for American planes).

I'm going to have to try this next time! I always have trouble with taking off on the Mossie!

I assume the references to RPM refer to Prop rpm setting. However, I can not operate the rpm levers, they are linked to the throttles and the keypresses to unlink do not work (R. SHift+p and L.Shift+i). Also, is there a cockpit guide anywhere?

[ilmavoimat]

It doesn't help that torque reaction pulls it to the right instead of to the left as it should.

you may have simplified engine operation settings. The mosquito does not have rpm linked to the throttles. The only way that will be occuring is via simplified/easy/automated (cant remember what it is called)engine setting enabled 

[deldalton36]

Thanks, I will check that. Good of you to help. TA!
