I've been training on the La-7 for the last few days and attempting to wrap my head around the concept of propeller pitch. So far I've used it either all the way on or off until I noticed recently that I was getting stuck on the runway (propeller pitch was accidentally left on "0" from an earlier flight).

So it occurs to me, rather than think about pitch angles I would try to use it like the gears/clutch in a manual transmission.

Bingo! Need to go up a hill? Go down a gear and floor it. Leveled out and want to top the engine out? Gear up. Set it to "0" and it works like the clutch when you just want to coast in for a landing but need to keep the engine running in case of a "go-around".

the projectile weights 330g ... i remember hearing that 1g tnt blows a pig paw apart. now what will 280g do...?"
you are talking about the entire shell the projectile is 3cm in diameter and about 4,5cm long, that is coresponding to my thumb and littlefinger combined http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

So what your saying is basically, decrease pitch at Hi speed and Increase at low? (otherwise I am confoozed http://ubbxforums.ubi.com/images/smiley/53.gif) - thats what I do and it seems to work - although I keep my Pitch at between 65-85% most times, unless really fast then I drop it back....

@Urokai... I think you are in the wrong thread for this mate http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif

A good article about the various means of prop pitch control is Those Marvelous Props (http://www.avweb.com/news/columns/182082-1.html) at AvWeb. La series use the constant speed type.
