Guys,

I did try a search on this but got too many returns everytime.

It seems that when the 262 gets up to speed on take-off, it pulls uncontrolably to the left. I have tried everything to get it to straighten back up but the rudder and wheel brakes won't start responding untill the speed get below about 60 kph. Once it gets to below 60 kph, it gets back under control.

Anyone know why it starts pulling left? I have checked, both engines on, rudder centered, etc.

Ok, both engines are on, but are they both SELECTED?
Otherwise, when you give throttle, you accelerate only one engine even if they're both ON...

If both engines are on, check the RPM gauges for the engines.

Sometimes when you select both engines and set the same throttle %, they will have different RPM for some reason. If that happens I just turn the engines off, then back on again.

...it might also be the case of the tailwheel not locking... It seems to be a bug and has been addressed...

...otherwise, I second that "both engines selected" suggestion...

the thing with same engine throttle but differen't RPM's has happened to me, and really is frustrating for takeoff because you have to control each engine individually in order to avoid a fiery death.

Also, make sure you have both motors selected (the worst is when you take fire, and shut down a flaming engine (usually stops the fire!) but forget to select the good engine when you are down, and come into a landing trying to throttle down with no success . . . man, that is not good.

Thanks to all of you guys. I DO actually have both Engines selected but I will keep an eye on the RPM's and let you know. Could it be weather?

Could be weather...I nearly had my P40 blown over in a nasty crosswind during a rainstorm in one of my pilot career games.

Try several different settings on the weather to see if its wind related (or turn off wind in the realism settings).

I find that by starting your number 2 engine first instead of your number one engine gives me the least problems, and once each engine is started pull you power to 0% and start the other and to the same with the power then select both engines, and letem rip, but not to fast or you'll be R.I.P.

Usually i start the left engine first, let it wind up for about 20 seconds then i select the right engine, and let it wind up for about another 20 seconds then i select both engines in preperation for the takeoff. Flaps are lowered to either combat or takeoff positions and a slow smooth acceleration to approx 85% engine power is applied. Using rudders to keep teh aircraft aligned down the centre of the runway, i let the aircraft gather speed until it reaches it's optimal acceleration period(usually in the last 1/4 of the runway) before applying full throttle and lifting off just before the end of the runway. Once i feel clear and safe (ie accelerating no fires) i raise the gear and throttle back to approx 80% power. Throttling back allows the engines to stop overheating though the need for flaps is required by this move. As the engine heat returns to normal i will raise the flaps and increase throttle to 85% and nose down a little until a stable speed is acheived.

That;s how i manage my takeoffs in the me262 and it works about 95% of the time in all conditions, occassionally i rush egine startup and get a rapid acceleration of one engine.

It does help to positivly select both engines ...

... I have keys mapped to Select All, and to Select None.


Once both engines are on, and When you want both engines ....

Select all
Move the throttle to 10%
Move the throttle to the setting you actually want.

If you actualy want 10% ... move it away from 10%, then back to 10%.

I find that the throttle settings dont take, unless I change them .... this is true of all multi-engine types, not just the Me262.



Avoid setting throttle to zero on the 262 - you can stall the engine, especially if it's cold.

My guess is that the pull to left/right on take-off is caused by a stalled engine - one that did ignite sucessfully, but has since gone out.
