SImples

If you do not have the mechanical power then it will blow out on heavy tail moves. Either increase the pitch range and / or go up in tail blade size.....

how big is the tail servo horn spacing are you sure its not to big ?

Surely my Electric has more power then the nitro so why would the nitro need bigger tails.

I have run the electric on 715 and not had problems like this

Had exactly the same yesterday on mine Paul, 700 with YS91 running about 1950 with 105 carbon tails. I did think I'd bogged it slightly and it didn't happen again but it was quite a big collective/cyclic move so maybe justa bit more than the engin can handle

Is the electric not a quicker tail speed.

It would depend on the gearing. The electrics tail may be spinning faster on the electric

Ah beat me to it wavey!

I was using a arm with 13.5mm now using 15.5mm
Feels better on the bigger arm. Travel is 95ish now was 114 at worse

I don't currently fly any ALIGNs and have never owned a TRex 700, but I'm sure I read something recently that the electric has a higher tail speed, therefor more mechanical gain.

**moonmanflyer** · 24-12-2012, 04:39 PM

it could be mechanical maybe the hub bearings need changing, but i would think it is a vbar issue as you are running the gains silly high.
Are you sure you have the correct settings in the tx, gain needs to be adjusted via the laptop on the vbar, i would do the full setup again

Sounds the same.
It's not bogging it loading a bit.

Can any one get the tail to wag with high gain. Is 115% to much? It's in the red

**waveydavey** · 24-12-2012, 04:45 PM

I'm flying again on Boxing day I'll have a word with Andy K

**Nick B** · 24-12-2012, 05:00 PM

Had it happen on my vbar v2 700e,too much main rotor pitch,no probs since reducing it to 11.5 from 13.Still climbs faster than anything i have flown lol
