I had read the thread on proboards about the crash...that was written before the problem was found with the pushrod. I would hope that's been fixed in the newer kit issues (?). I know there is a fix on the Hangar 9 site.
Keep in mind, too, that the crash was a cooperative effort between pilot and plane.
I'm not all _that_ experienced, but when you get into trouble inverted you pretty much want to grit your teeth and land inverted unless you're waaaay up there.
Since I have "ZERO" experience, I'll ask about props: What difference would the 3 blade have over a 2 blade? Faster?
All else being equal -- uh, wait -- all else never is equal.
If you put on a 10-5 3-blader in place of a 10-5 two blader, and all the blades are alike, then the 3-blader will load the motor more. If the motor doesn't bog down from it, it'll produce more thrust (note the "if"). If that 10-5 two-blader was the right prop, then the three-blader will probably make the whole assembly sick.
Two blade props give you more thrust for the power (generally), are a lot cheaper (generally), and need to be bigger diameter for the pitch to load the motor the same (generally). It's actually the bigger blade disk that gives you the higher thrust efficiency -- but at the same time, you're reducing your ground clearance.
In the absence of guidance from experts, I would get a handful of two-bladers that seem to be roughly equivalent to your three-blade prop, with varying diameters and pitch. Then I'd experiment to see which works best.
But if you're an absolute newbie, I'd recommend that you just fly the plane as designed at first, and do the refinements when you're a bit better.
Am I learning ANYthing?
Yes, but you need to get out and fly!!
