TAKEOFF!!!

Change the weight. Lighter will make it go faster, heavier will make it go slower.
 
Thrust - engine Horsepower, Prop parameters (pitch, dia, efficiency, rpm......) Not forgetting drag & releasing or applying the brakes.....!

Do you ask this as a developer or as a pilot?
Is this about a specific aircraft or about takeoffs in general?

Just to add to the tips above:
If you are flying a taildragger, raise the tail as soon as you can.
If you are flying a tricycleplane, do not raise the nose until just before you want to leave the ground.
This way the aircraft will be parallel to the runway and have the least drag.

If you at a higher altitude, adjust the mixture to get the best power out of the engine.
 
Thrust

Tell us what aircraft/model you are talking about. But generally you can mod prop/turbo prop/jet engines to give you more 'static thrust'. Too much and you won't be able to keep it from moving, and when landing you will need to add more drag to flaps, or increase spoiler drag or you won't be able to get under 200/300/400 kts (depending on engine type) so you won't be able to make 'normal' landings with it. I am curious which airplane you are dealing with as I can help you mod it. Also, if you crank in +4.0 of up pitch trim it (any) will take off on it's own at 'x' kts (watch out for STALL!) although this 'trick' does not depend on higher speed(s) but (mostly) 'dynamics'. If you want to 'fiddle' with specs here is the sections to adjust:
------------------------------------
-type 1 //jet

[jet_engine]
thrust_scalar= 1.3 //*** increase to 2.5?
------------------------------------
-type 0 //piston

[piston_engine]
power_scalar = 1.3 //*** increase to 2.5?

[propeller]
thrust_scalar = 1.3 //*** increase to 2.5?

------------------------------------
-type 5 //turbo-prop

[TurbineEngineData]
fuel_flow_gain= 0.011 //Gain on fuel flow
inlet_area= 1.0 //Square Feet, engine nacelle inlet area
rated_N2_rpm= 33000 //RPM, second stage compressor rated value
static_thrust= 158 //*** increase to 350? //Lbs, max rated static thrust at Sea Level

[turboprop_engine]
power_scalar= 1.0 //*** increase to 2.5? //Scalar on Turboprop power
maximum_torque= 1865 //*** increase to 2990? //Maximum torque available (ft-lbs)
