ok, so here's the problem: When I throttle up, everything seems fine, then once in the air, even just one foot off the ground, the 4 in 1's light turns red, even on a full battery pack.

I recently replaced the spindle, but I'm pretty sure I put everything back correctly, and even if I didn't I dont think that would affect the 4in1. I tried reducing the gain to no avail, I made sure everything was plugged in properly in its proper place, but nothing seems to work.

Is this something normal that I havent noticed before, or could it be a broken 4 in 1?

Can you only go one foot off the ground or more? Are your blades tracking and do you have enough positive pitch? I just stopped caring when the light came on. As long as the helicopter goes up it is fine. Just come down when you can't go up any more.

yes I can still fly, and I checked the pitch of the blades, their fine too. Nothing else seems to be wrong
