I have a blade 400 that I have been hovering now for a few days and feel like it's set up fairly well. I am using a DX6i Tx and my question is, the difference between it gaining altitude rather quickly and dropping too quickly seems like it's less than 1 click on the left stick - it's really hard to maintain a consistant hover height. I put 0 pitch on the blades at mid-stick, Norm throttle curve is 0, 50, 80, 90, 100. Norm pitch curve is 45, 48, 50, 75, and 100. Not sure if those have any effect on this but thought I'd let you know where I was set at. Any thoughts on what to look at?
Thanks.

Not sure about the DX6I but on the DX6 I removed the back panel on the transmitter and removed the detent or steel spring that ratchets on the throttle stick. Others have placed a small piece of heat shrink tubing or fuel line over the rachet arm (this way keeps a little tension on the stick). This will give you a WAY smoother throttle for heli flying.

Never thought about it being a mchanical issue with the transmitter, but that makes sense. I guess that's why the heli version of the DX6i has the smooth throttle stick. I am using my Tx that originally was used for my planes, and it clicks. I'll try and see if I can do what you did. Thanks.

I would have to agree with that comment as well, on my heli DX6i it really does take just the smallest hint of a bump to change altitude significantly, and i've seen how big the ratchets are on the plane versions, so if everything else is perfect that would be more than enough to screw stuff up. Here's to hoping it's your only problem!

Removing the ratchet action from the left stick should help some. Remember simple physics play here too. Takes more energy to climb than to descend the same distance as gravity is pulling against you.

I adjusted the metal detent strip on the back of the throttle so it is smooth now. I'll fly tomorrow and see how it does. Thanks.

Helped a lot, thanks!

Excellent!

Most radios sold in a helicopter specific version have the ratchet action disabled on the throttle stick. I'm used to even flying my planks with a smooth throttle stick these days.

you can reverse the strip that ratchets, and bend it backwards a little and put it back on upside down, that will allow you to be able to still adjust the tension, and take the ratchetting motion out...

Do you have a pitch guage, (if not get one) if its too sensitive, change the pitch settings from +12 -12 to something a bit lower like +10 -9 That should help alot for learning....

also make sure to fly in idle up, otherwise the tail can get away from you....

did you set you mid stick to zero with the throttle hold on, or the motor disconnected? the dx6i has 3 different pitch curves. i used to set my hold curve to my normal mode curve so that i would not have to disconnect the motor, so defiant check that. also, check your high stick an low stick are at your desired end points in stunt mode. if not you may need to adjust the pitch setting on your swash mix.

personally I fly with 10, 0, -10 in stunt and 10, 0 , -5 in normal.
