Tail kick on punch outs 600l dominator castle hv80 spartan vx1e I have tried messing with the gov gains a little not sure what way to go with it everything else is pretty good just get that kick. I’m running almost 13degree cyclic wondering if I should maybe bring that down to 12 and messing with the precom on the spartan idk

Mabey one day i will actually land one of these things !!

The tail kicks out ? Only on hard climb out.?

Try raising the tail gain first until it starts wag and back it off a couple % and then the pre comp if it still doing it.

After all of this if it still doing the same try larger tail blades and restart the procedure mentioned above.

In that case raise the precomp a couple of points at a time.

Btw what HS are you running when this happens

Had this problem, as said I adjusted tail precome either left or right, you have to play around with it.

The 600L Dominator needs to be running at least 2300 rpm? What rpm are you running?

As a result be careful using an 80A ESC on there, the combo kits come with a 130A ESC.

The heli is way over geared if you ask me and would be better suited to running 10s 3700-4000mah instead of 12s 3300mah. Your 80A ESC would be happier and you would get much longer flight times.

The problem when a heli is over geared and you don't want to run crazy head speeds is exactly what your seeing. The motor has too much left in reserve and when you give it a handful of pitch that big torquey motor will try and spin that heli round in a heart beat, coupled with the fact that the tail isn't spinning as fast as it's meant to so has greatly reduced thrust. The only answer is to run loads of tail pre comp and/or run longer tail blades. You may also need to turn your governor gain way down.

You could still just about run 2300 rpm on 10s. You would gain at least 20% more flight time.

I would think an 80A would not be big enough, would it not overload easily if not careful with collective management, the 550 L came out with a 90 esc and now moved too a 100A esc.

If your model helicopter is over geared as Richard mentioned. Then about the only option you'll have is to lower the collective from 13 to 10 / 11 and use a lot of precomp.

Maybe going 10S isn't a bad idea . Though you might need a higher rated esc. I would need more details about the available gear ratios.
From my personal experience 9:1 - 10.5:1 is more ideal. I find 11:1 is to much torque and inefficient ....too much spin

I'm assuming the 600l runs mod .08 tail ratio like the 600e Pro. If so I had issues with blow outs ect.. I upgraded to the 3 blade setup setup problem solved no blowout no kick no nothing solid!

3blade head and tail or just the tail I was looking at that two also what size blades were you running? The tail actually holds well just on punch outs it kicks like 10%

Why do you think they changed it?!

Nope. Lower voltage with THE SAME gearing actually reduces current draw, if you were to run 10s AND gear it up further so it ran the same max headspeed then yes you would need a higher rated ESC, but this idea uses the same gearing which actually reduces top end power, lets the motor and ESC run at a more efficient higher throttle %, thus reduces current draw. You can carry more battery capacity for the same weight 3300 12s vs. 4000 10s, thus greatly increased flight time. It's a win, win.

Gear ratio is fixed on the Trex 600's.

Upgrade the ESC and run a higher head speed (thus tail speed) and say good bye to flight time OR get yourself some 5s 4000 li-po's and reap the huge benefits, if you are not happy I will pay for the 5s 4000's!

There are plenty of ways to stop the tail kick on punch outs, I just suggested going 10s as it will a. stop the tail kick b. give you increased flight time and longer lasting batteries.

You can increase the tail thrust by adding longer tail blades or 3 blade tail or using higher tail gear ratio gears from another Align model (I forget which, either 600N, original 700E or 700N). Other ways include running higher head speed, increasing gyro gain, increasing tail pre comp and turning gov gain down.

Good post to bring this up.
See how many of you old dudes remember.
We used to use Revo mixing
Now we have all these badass Gyros doing the work

I just thought I'd throw it in cold day here and home

Lets do the time warp againnn !

Tail pre comp in the gyro is kind of the same as Revo mixing but instead of a throttle to tail mix it's a pitch to tail mix.

The big difference is the old computer radios was it set up right you would spin around in inverted.. and not expecting it.. now we're having fun

Yes you would need equal throttle and pitch positive and negative to avoid that.
