Hello!!!
I'm starting to loose my patience.
The tail once seems to be ok for a while, but after a while it starts drifting. Let's say it like this: weaking battery seems to have more influence to the tail motor than to the main motor. Its so annoying because i need to land and trim it to fly again. I tried everything- changing pitch curve, mix ratio in rx, sensitivity in radio. Its a total disaster because i think i got it and then the battery ends and with a new one i must start all over again.
Now what i did. I removed the v-cable between esc's and soldered cables. I gave power cables for esc's directly from battery. I also compared with my friend's 4g3 the tailrotor and main rotor revs and it seems they work similar. Although at normal mine seems to rev faster. He gets 2600 at half throttle and 2100 at max and mine 2900 and 2700.

I think throttle curve could help here a little but at my manual it says i can't change it- 2605A rx.

Could someone please help me?

So, I'm almost home. After fine tuning od the RX gyro sensivity and pitch it's pretty ok. But right after take of it has too strong tail so i give some full throttles one after another, the main rotor slows down a little and it is ok till the end of battery. Does it sound ok for you guys?

Walkere electronics have always been questionable at best...

Friend of mine sent his Novus back to Tower for a refund....

He got fed up trying to make the tail hold position..

There is a ton of information on the set-up of this heli on RCG's. If you go to buildem336's 4G3 DBL vid, you can see what the proper set-up can do for this little heli.
