I guess that was me. And I will notch my blades next time I have them off just to see. My tail rotor blades on my Trex will fold up. I had a very hard landing yesterday that broke the landing gear. The tail hit so hard it folded up the blades. You can't tell me that if they were more rigid it would have saved parts. The tail is gear driven on that one.
Have you flown yours outside? Do you kmow that a "hammer head" is?

Here's my awesome Ecoman $10 heli . I bought this thing over a year ago and have used it (and crashed it) many, many times and it has yet to break. It flies really well too, amazing that it was only $10.

Be careful Greg... You might get hooked..
Here is a landing gear break... I had totally reset my radio and never set the pitch curve, so it was linear.... Very, VERY twitchy at hover as far as positive to negative go on the collective. Resulted in a mild crash. I placed the handle of the awl in the break.
Fixed.. Notice canopy damage. That was from a heads in inverted crash.

You should be steering that out by now. (Kevin's talking about the hole wear on the pivot point of the flybar. It results in sloppy linkages between the servos and the blades themselves. Mine is also getting worn, even with lubing it.)
Wouldn't have saved parts in THAT case (large bird with gear drive tail)
On the mSR, I'm convinced that notched leading edges (or excessively pivoting blades) reduces blade damage during a rotor strike, BUT transfers the stress to the grips instead, with a twisting force that rips the screws out sideways. Pull back against a notched blade and think about where the stress forces will act. Notching makes the blade come to less of an "instant" stop, by allowing the hub to continue rotating at full force for a split second before the blade brings it to a snap-action stop. It looks like it would make the stresses on the grips and the blade mounting screws more severe.
I broke my first set of grips 5 minutes after the blade-notching experiment.
I flew outside once, knew there was too much wind, did it anyway.
One over-banked turn, slammed into the driveway sideways.
Second launch, wind picked it up and carried it nose-up 50 feet, so I panicked and cut it.
Came down like a feather and hit the frozen snow. I went back inside.
I really need to borrow the high school gym for a while.
OK, I give up, what's a hammerhead?'89 Hydrostream Vegas XT, '90 Merc 2.4 Bridgeport PCU EFI

If anyone's looking for a small little camera that would fit on an RC/ heli, and actually takes decent video....there are lots of guys on the RC heli forums using this. I ordered one yesterday from ebay...$12

Obviously those cameras are made for the mid- and larger-sized heli's, not the pocket micro's... Very cool though.

I can steer it out no problem, letting others (first timers) fly it has cost me 2 tail motors cause it wont hover like it used to
my blade grips look like new they must still be in one piece because i bought a spare set after being told they were the weak link
