Roll of death during tic toc

[BladeScraper]

A couple weeks ago my buddy (the original owner of this Nano) came over and wanted me to look at it. It was doing the same thing (or at least, a similar thing) except during front flips. Was perfect during back flips but if I front flipped, it front flipped itself into the ground... couldn't figure it out so he put it back in the box. Then he came over yesterday and we flew again and he just gave me it. I just needed to figure out the flip issue. I changed the swash and it flew fine... I thought I had fixed it.

Since then, I've been flying pretty hard with my Nano BL with Mild V2 conversion and doing tic tocs, funnels, piro flips, etc. Perfect performance and nothing other.

But earlier on my last battery it started acting funny. I would start doing a tic toc and it would roll itself into the ground. It looks like the 300X right roll of death but to the left.

It only happens when I give left roll, not right. It looks almost like a servo link came off but upon checking, its perfect. AR guide is still in the slot and stuff. I can fly hard 3D all battery if I don't do any aileron tic tocs...



Servos are all perfect (other than a little dirty) and there is no binding. No loss of bind issues.


What could be causing this?

Check the solder joints going to the servos. Mine did that when they started to break loose. When you throw it that direction, it causes the servo connection to come undone for a split second. However, the servo itself takes a few seconds to reinit. Which means it doesn't respond to the input needed to keep it from diving.

Why would it switch from front flips to rolls? And ONLY when doing a LEFT roll and ONLY during a tic toc

G-forces and a servo that is going bad... that is my bet!!

I think it was the servo itself. Not the wires/soldering. Because the left servo for some reason got stuck before it got all the way down (i.e. left aileron). I would assume this is the cause. Anyway, after changing the servo it works perfectly

Thanks guys
