Tail expectations

[stockracing]

My tail is setup with 401/9254 combo and is rock solid during hover, fast forward, slow backwards flight, even with some crosswinds. No wag at all. The ball links are about 14mm from center of the arm. Limit on the gyro is between 80-100 and 0 delay. The tail slider has no binding, as well as the tail control rod.

However, during collective punch outs, whether mild or hard punch outs, the tail swings out to the right. With this issue, I always have to give it a little right rudder to hold the tail. Is that how it's suppose to be? Although I haven't tried inverted punch out if it'll be the same.

I am using the stock batman tail blades. The headspeed is around 2000rpm with an OS 50. Pitch curve is +/- 12. I can hear the engine a loose a liitle bit of headspeed when this happens.

Am I expecting too much from my tail?

Try increasing the gyro gain a little, and some carbon fiber tail blades!

fwiw...Are you using a governor ? If not, try about 20% cyclic to throttle mixing..Gain should be around 70%, travel left/right maxed out mechanically...set it up at neutral with 2-3 degrees of right t/r....

make sure your in heading hold mode "AVS" , tail kickout happens in rate mode...

Mine does the same thing but only on hard collective. Mild collective its fine.

Yes its in HH
Yes its between 80 and 100 on limit.
Yes its 70% gain in the radio.
Yes I have a govenor.
Yes I have the tail maxed out mechanically.

Same story, plastic blades, HS at 2000 with os50 and +/-14 degs. Mine is not bad but it will drift a bit. I notice it more in ail tic-tocs but it shows up a little in loops also. The tail already has a little shake back and forth (not a wag) in hover. Maybe a hunt? Anyway, if I turn it up it gets worse and I am afraid I will burn my servo out.

Think I am gonna try a shorter servo arm to see if that will help. A buddy has a 600E with carbon tail blades I can try also.

do you have the pro or the sport model?

[rototiller]

I have the sport.

Get the QuickUK thrusted tail and either the white carbon align tail blades or the radix 92's. With that much pitch (12-14) you guys might want a little more headspeed also, try 2100-2200. Get the metal grips before winding the headspeed up though :)

ive seen this before , make sure your tail is rotating in the correct direction. if looking at the heli from the passenger side (right side) the tail blades should rotate counter clockwise so the blades rotate up into the main blade downwash. if the tail blades rotate clockwise then the belt is 180 deg off.

stockracing....What regulator are you running? I just put a HD one on and my tail has cleaned up a ton !! No more little hunt. I will play with the gain next chance I get to see if I can turn it up some. That would kill the little bit of drift I have. I was too busiy playing with the new found speed of the servos (6V) to notice the tail :D

Agree with above... CF tail blades and make sure Revo mixing is inhibited!!

I got my tail problem solve last weekend. I'm not sure if that's the correct solution, but it stopped the tail from swinging out, no matter what I do.

I kept all linkages and settings the same except for the limit setting on the gyro. When I was having a problem, my limits were approx 95 to avoid binding on either side. I bumped it up to maybe 110, but it binds and both ends on the ground. I've heard people do that and was told that even though it binds on the ground, it will never bind up there. So, what the heck, I tried it and sure it was locked in.

You might also want to make sure that your Gyro is on a flat surface, that "H" mount seems to have lots of people mounting them in a slope.
