I am running 6s.

The only thing now is Im right up to 140% on my gyro limits where before I could only get 100%, so I may need to put on a bigger servo horn.

done that everything was reversed.

Whats wierd is Im sure my freind pointed it out to me they were on backward before I crashed but it was not blowing out, only every now and then durin very hard tic tocs, so Im not going to get to exited until I fly it, but Im quietly optomistic.
Maybe it might hold better than before and make my tic tocs not so ugly.

Its not blowing out anymore, haveing the slider moveing the opposite direction to the sharp edge of the blade was reduceing the travel enough to make it blow out, would not of thought a single half flip to inverted would use so much tail pitch but it must do.

Just for fun, can you post some pictures of the tail rotor stuff? It's odd that you'd have to build the tail "wrong" in order to "fix" the problem, especially since there are thousands of these helis flying, built as they should be, and not seeing your troubles.

Its definately the right way that I have it now, the same as my 600e and how it is in the manual, it was the wrong way before thats why it was blowing out.

When the tail pitch slider is to the right, the tail rotor give right thrust, where before when the pitch slider was to the left the rotor was thrusting right.

You would have noticed that when your tail is set up correctly you can always get slightly more right rudder than left, where the way I had it I was getting more left and not enough right rudder.

I looked in the Trex500 manual, and one diagram shows the grip control arms on the leading edge and then in another diagram it shows them on the trailing edge.
Either way its not blowing out anymore so Il leave it as is, the way it is now is the same as the main blades with the control arms on the trailing edge.

I thought most heli's have the tail grip control on the leading edge.
I always thought it was strange that my trex 250 had the control on the trailing edge for the main blades.

Every heli I have or had has the control rods on the leading edge of the tail blades and trailing edge of the mains.

I did set up the tail blades with the conrods on the trailing edge once and never could get the tail to work right.

I literally never use the word literally right.
