Default Hovering issue..

Hey, I'm practice my hovering, getting ok.. What am I doing wrong though. I can hold it still for about 10 second and then it starts shooting off in another direction..??

Practice, practice, practice. Hovering is like standing on a ball.

You are probably over correcting, do you have some EXPO in the radio?

It just takes time, soon you will be able to hover in your sleep.

Do a lot of sim time,

Craig

You have it in good trim, right? So that when you take your fingers off the sticks it doesn't fly right off? That can make all the difference in the world... Just a thought...

To be honest... I havent adjusted any settings on the controller. I'm still flying everything stock settings.. I guess I need to play around a little with the trim switches on the dx6i huh..

Oh wow...first off go to Adjust list D/R& Expo settings and set your D/R to 70% and set your expo to +15%. This will tame it down quite a bit. You may even want to go lower than 70 that's just what worked for me. Dual rates slows down how fast the controls move and the expo makes the sticks less sensitive around center. I highly recommend John Salts stuff for taming down the 400 to make it more beginner friendly.

This book is well worth the $15 I've gotten my moneys worth many times over out of it.

I agree with Avidflyer,but, I like 30% expo. The very best thing that you can do to improve your hovering, besides practice, is replace those stock cyclic servos with HS65MG's. When I did this, it stopped all that "wandering off" stuff. The junk stockers are not even capable of centering in the same place twice in one day !

+1 for adjusting the trim.

You might also pay closer attention to the main rotors. While you think you might be holding it still, it really is the bird is just transitioning before moving off in another direction.

To me (and I'm a newbie) getting it to hold for a few seconds was one of the steps to a solid hover - but I had a ways to go before I was really solid. Keep it up and soon you will feel even more in control.

One other thing to consider is that the flybar should move silky smooth with very little drag. On my used B400 one of the blade grips would grab the thrust bearing and it made the bird sluggish and tweeky on cyclic. Landing was almost impossible to do without blade strikes.

Good Luck, Don

grease the thrust bearings really well. this will allow the rotors to move smoothly and let the flybar rock easily as well.

Yeah, your right but I actually had to drill the ID of the blade grip to get a few thousandths of an inch clearance for the thrust bearing. In my case the thrust bearing was a press in and it didn't work right.

YMMV, Don

The 2 cup washers of the thrust bearing have different inside diameters. The larger one goes on the inside closest to the head.
