Unstick problem

Some time ago, I read a tip which detailed the parameter to 'tweak' in order to get an aircraft to unstick at roughly the correct speed.     Can anyone give me a reference?    I have one just now which doesn't look like it would ever unstick regardless of how much 'up' elevator and/or 'up' trim is applied.      They just don't build runways long enough!

I've never heard of that. Mine unsticks fine as long as I've done the calculations correctly.

did you tell the FAT@$$ back in 23B to get off the plane?? that might be the problem.

also, are you trying to take off with 100% fuel and an overload of luggage?

Make sure your auto pilot is off

Make sure your auto pilot is off  :o before you start your take-off roll


...and don't forget to manually trim the Aircraft correctly for take-off.....Take a peek at your Elevator Trim Wheel setting.... ;).... ;)....!

My technique for quickly "unsticking" in my GA Piston Props, is to spin the Elevator Trim Wheel for a slight "nose-up" position, accelerate smoothly down the runway, and then apply one notch of Flap once up to speed...

This is often enough to catapult the Aircraft into the air, and climb all by itself, without any further assistance from me!... :)...!

(Just remember to cancel the Flap(s) once in the Cruise).

Excellent technique for short-field take-offs!... :-*...!

Thanks to all who took the trouble to reply.     Very interesting.      Unfortunately, none told me where I might find the tip I referred to.

Which is the one and only Aeroplane that you are having trouble with?

...link to the Download...so that we can try it out, for any errors in the design...;)...!

If it's not rotating at the calculated distance down the runway and your numbers are all good, it sounds like a CG problem and one of our more enlightened members can probably provide the fix.
