Extreame Left Roll / Yaw On Takeoff.

[mmaruda]

You must have some autorudder or take-off assist one. Firewalling the throttle?! That results in the plane being all over the place on my end, and adding just 10m/s crosswind = terrible, terrible damage.

 

My current take-off parameters for a smooth run are: trim 5 degrees rudder, slight trim to tail, lock the tailwheel, manifold pressure no more that 30 with a steady and very gentle increase after reaching 50 mph. That requires a lot careful rudder operation.

 

Moving the throttle 50% up, not to mention firewalling it before achieving a significant speed results in Toktyo-drifting all around the runway and eventually crashing. The Mustang is one wild pony!

Well I found my answer, there is an auto rudder check box under special. I guess I should have read the readme. They snuck that one in.

Just learning this myself. I have found the best takeoff is to do it exactly like the flight manual says as opposed to the training mission. I suppose the training is trying to make it easier by limiting you to 51"mp and says so. But the manual says go the full 61" and 3000 rpms. Push the throttle forward swiftly but not too sharp. Keep the tail down at first and let it up slow right before 100 mph. It takes off smooth with no wing drop at all. The higher power is easier.

It's very specific and depends on your skill. Gentle TO - have 35-40", gain 60-80 mph, gently rotate and add MP gradually - is better for initial education because it's easier to keep the plane straight with rudder.

 

Full throttle TO requires more or less fast tail raising to avoid 3-point TO. Fast rotation requires accurate and coordinated rudder input - add right rudder as you are rotating then, as the plane is at two wheels, rudder input must be less than before rotation (P-factor decreases as AoA decreases).

Yes that's of course true. I found that the more I practiced the more I could just put the throttle full forward and go. There's some language in the manual I found helpful "this power setting should be reached as quickly as possible" like don't jam the throttle forward but don't hesitate. With practice it becomes a real smooth takeoff. My own learning experience was once I got to this point takeoffs became really easy.

It took me maybe four or five takeoffs before I was able to do do it remotely close to right, but by the tenth or so, I became able to do a "immediately firewall it" takeoff with minimal yawing. Yo-Yo is absolutely right--it is critical to raise the tail as soon as you have the airspeed to control the gyro yaw (maybe 60 MPH), so that you don't fly off the runway in the 3-point attitude and stall as soon as you leave ground effect. (And even if you manage to not quite stall then, it's extremely dangerous because you will stall and crash if you have an engine failure at that AoA and altitude.)
