Full throttle issues.

I have a QAV-R 5 " and when I give it full throttle the nose wants to dive forward and slightly towards the left. I'm new to this sport so sorry for rookie questions! but please can anyone help me with this problem? thanks in advance.

Welcome @n3il, a little hard to envision, can you post a video clip to show it?

 

[n3il]

THank you @HighTechPauper and yes I will make a video but will have to be tomorrow. Its night time now.

10-4, will keep an eye out for it. This one could be a tough one from the sounds of it. It almost sounds like a bad esc or esc calibration, or bad motor, causing right rear to be spinning faster than left front when you punch it. That could cause the symptoms you describe possibly.

Ok..will try recalibrating ESC's. the motors are new, they sound good when at idle but then again I have no clue if that matters or not. So ill get the video uploaded and take it from there I appreciate your help so much!

Don't thank me yet, but I got my thinkin cap on... could be so many things from vibration to faulty FC to cold solder joint etc etc etc. We'll see if the vid gives any clues.

If you are running DShot, dont bother calibrating, DShot doesn't need cal. If OneShot or Multishot then maybe that will help, I doubt it, but it probably cant hurt to try.

Could be a tuning issue

Could be a tuning issue

You're right Vv, could be as simple as a tuning issue, you or Green will need to help with that I'm guessing, not my forte'... yet.

Nose dipping means D is low
