RoyBob -> Blade 400 Sudden Spin Down (5/11/2008 6:50:21 PM)

I've search the forum to see if there's a discussion about this already and can't find one, so my apologies if it's been asked and answered before.

I was hovering with my 400 using a 3s2200mah lipo. About 6-7 mins into the hover, the heli suddenly lost headspeed - as if the throttle were cut back.

This is not the same behavior as the low voltage cutoff where throttle is gradually cut back.

The heat sink on the ESC was quite hot, making me wonder if there's a thermal issue with the stock ESC.

Any other experiences like this?

Make sure tail drive belt is not too tight. It will cause alot of drag and could cause what you are describing. I run my belt as loose as possible without it slipping.
