Once&future, the technique should work equally for trigears as for taildraggers.
First trick is to judge getting your tail as close to the fence as possible as you come around followed by full power at a point about 20deg from takeoff direction (varies with aircraft and thrust).
The idea is you already have overcome tyre/wheel rolling resistance plus start and acceleration of the 'mass' and the bonus is that the prop is being moved into undisturbed/clean air, rather than turbulant/dirty air as in holding brakes and releasing, plus as noted, no rock damage.

Thanks, I use the rolling takeoff quite often but always to the left because with my bird using p-factor to get it around 180 degrees is advantageous. It makes sense that it would help straighten out the right turn, the harder part is beginning the right turn :) especially on packed snow and ice! I'll play with it both directions now that we are back to bare ground.

Judicious use of throttle until one is assured of making the beeline down the runway is advised :O

Wasted runway, Maule.com makes a good point. I saw two examples of it yesterday, not a shortfield situation but still bad technique. The first was a Beechjet that was 'position and hold" at least 1000 ft. down the runway. I have no idea what they were thinking. After he took off a G 4 lined up with about 250 feet of pavement behind them. On a 200 ft. wide runway there is no excuse for not being able to comfortably line up, without dragging the brakes, within 100 feet of the end of the pavement even in that class of airplane. ( I was next and used 23 ft..... :D )

Along with being sort of narrow and a little brushy, this spot is also kind of short. Will Crash make a J-turn here I wonder or power up with some brakes?

This was field approved out of the FAI office. It's pretty much a no brainer. Get in touch if you want more info. IT's not hard, and makes a world of difference. ...


I'd like to hear more about this. How about starting a new post to explain/discuss the mod?

I'll post a picture. First, I'll have to TAKE one, of course. Might be a day or two.

And, that runway that Crash's airplane is on in the weeds is plenty long enough to leave without holding the brakes.

If you like your prop (and it's hard not to at the current price of props) DO NOT hold the brakes on stuff like this, and run up to full power.
