I have bean using the DD tail mod for a long time.
I finally burnt out my last motor and had to go back to the original motor and tail blade. I took it outside today to try it out, now I remember why I changed to the DD tail. It had severe tail wag and when turning hard the tail would almost stop spinning. This got me to thinking That maybe I could take some material off of the trailing end of the blades, and thereby taking some load off of the motor.
I scribed a line 2mm along the trailing end and cut along the line with a pair of scissors. Fired her up and alot less tail wag. Cut another .5 mm And tried it again, even better. each time i cut more material off of the blades there was a significant tail motor increase in speed. It's 9:00 pm will have to wait until tomorrow to try it outside.

Has anyone else tried this? Your input is much appreciated :

DAy 2:
I took the heli outside today to try this mod. in the wind.
There was a 5 to 7 mph cross wind in the back yard, fired it up.
What a difference, much less tail wag and seemed to hold a heading much better. Still could be better, so I cut 2.5 mm from the tips of the blades and tried it out again. This is getting better all the time, it holds turns much better and hardly any tail wag at all.

So far I have taken 2.5mm off of the trailing edge and 2.5 mm from the tip of each blade, and the tail motor runs at a higher rpm to compensate for the smaller tail blade.

this seams to me to be a good tail mode if you are stuck with the original motor and tail blade setup, also gives you more ground clearance.

I will go back to the DD tail when I get to the hobbyshop this week.

Thanks for the info on the new mod. I am now using the dd tail mod, but it takes about a week for any spare parts to get here as we have no hobby shop in San Angelo. If my current dd motor goes out I will use your mod to get through the week.
Thanks
